This study aimed to determine the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes and if there were significant differences in the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes using three different proportions of ingredients per treatment in terms of aroma, color, flavor, texture and general acceptability. The present investigation employed experimental design to establish the level of acceptability of the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus Japonicus) Flakes. There are three treatments subjected for evaluation using a Researcher made Survey questionnaire. These were Treatments A, B, and C. There were fifteen (15) trained panels composed of faculty of NIPSC Ajuy Campus that were purposely selected to evaluate the product. The data gathered were analyzed using the mean, standard deviation and the Friedman’s Test (Freidman’s ANOVA). The criterion for rejection and acceptance of hypothesis was set at 0.05 level of significance. The study was conducted at NIPSC-Ajuy Campus, during the 2nd Semester of School Year 2020-2021. The findings were based on the data and the results of the analysis obtained were as follows: Treatment B with 150 grams of threadfin bream flakes was found to be “extremely acceptable” and comparable with the commercial spring roll wrappers (Treatment A) in terms of aroma, color, taste, texture, and general acceptability. No significant differences was found out in the acceptability of the Development of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes in terms of aroma, color, taste, texture, and general acceptability. Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes has suggested retail price of P2.65 which is more than 100 % higher compared to the commercial spring roll wrapper with selling price of P1.00 per piece. Finally, it was recommended that continuous research and development shall be pursued in case commercialization of Spring roll using Wrapper with Threadfin Bream (Nemipterus japonicus) Flakes is considered especially in the cost aspects. A feasibility study shall be conducted first before commercialization is pursued. Other pelagic fishes shall also be ventured and tested to fortify spring roll wrapper. Although results positive results in terms of acceptability, researcher shall look into possible ways to lower the cost of the product to ensure profitability. The Municipality of Ajuy along with the academic community and research authorities to take action on making researches that shall promote the utilization of pelagic fishes in the town. This actions shall enable the economic development of the town that can help resolve poverty and shortage of food in the Municipality of Ajuy. The said activities shall also promote entrepreneurial spirit especially the small and local businesses in the community

The population structure of three Nemipterid species (Nemipterus japonicus, Nemipterus bipunctatus and Nemipterus zysron) from the Gulf of Suez was investigated. A total of 3663 specimens (2597 N. japonicus, 576 N. bipunctatus and 490 N. zysron) were collected during the fishing season 2014/2015 in the Gulf of Suez. The maximum life span estimated from otolith reading was 5 years for N. japonicus and N. bipunctatus while, it was 4 years for N. zysron. The parameters of von Bertalanffy growth equation were L∞ = 31.66 cm, K = 0.24 year−1 and to = −1.2 year for N. japonicus; L∞ = 29.55 cm, K = 0.26 year−1 and to = −1.2 year for N. bipunctatus and were L∞ = 24.69 cm, K = 0.38 year−1 and to = −0.84 year for N. zysron. The estimated exploitation rate for the three species exceeded the optimum exploitation rate, indicating an overexploitation of the nemipterid species in the Gulf of Suez. The yield per recruit analysis revealed that the fishing pressure of the trawling fleet in the Gulf of Suez, has overridden the critical level. Findings suggest that decrease in the fishing effort of trawl fishery and increase the length of the mesh size is required for the protection of the nemipteridae resources in the Gulf.

The mid-water multiday trawl fishery along the north-west coast of India generally targets adult largehead hairtail, Trichiurus lepturus. Bycatch landed by the commercial mid-water multiday trawlers operated from Veraval harbor during August 2017–December 2019 was investigated by analyzing catch composition with respect to its spatial and temporal patterns. A total of 834 bycatch sample observations from mid-water trawl fishery were examined. Bycatch comprises of 123 species and account for 53.36% of the total catch. Highest composition in bycatch comprises of teleosts (62.09%), cephalopods (35.88%), crustaceans (1.47%) and elasmobranchs (0.56%) respectively. Uroteuthis duvaucelii, Sepia elliptica, Nemipterus japonicus, Otolithes cuvieri, S. pharaonis, Priacanthus hamrur, Sepiella inermis and Saurida tumbil were the dominant species with high annual average catches; and together contributed 50.30% of total bycatch. Discards formed 6.32% of total catch and consisted of 62 species belonging to 29 families. The most common discards were juveniles of S. tumbil, N. japonicus, Platycephalus indicus, O. cuvieri, Johnius glaucus and T. lepturus. CPUE of bycatch differed significantly between the seasons with the lowest being in summer and highest in post-monsoon period. Minimum bycatch rates were observed in the offshore waters than inshore waters. Endangered, Threatened and Protected (ETP) species listed in CITES as well as IUCN were also observed. The present study revealed that quantities of bycatch landed off northwest coast of India in the Arabian Sea were relatively higher than that landed by mid-water trawlers operating in other parts of the world. Hence the mid-water trawl fishery operating in north-west coast of India and targeting largehead hairtail needs to be closely monitored to mitigate and reduce the quantity of bycatch landed by them.

Spawning potential ratio (SPR) is an important parameter to ensure fish stock reproduction, recruitment, and sustainability. This approach more efficient and effective applied to poor and limited information and data to management. Therefore, we used the SPR approach in small scale fisheries, particularly on Nemipterus japonicus species in Labuan-Sunda Strait area. This research was conducted in the Labuan fish landing port from 2013 until 2019. The length data were collected each year and then analyzed using the basefoot ecologist toolbox application. The result has shown that SPR of N japonicus ranged from 1 to 6%, and it’s relatively low and potentially unsustainable. Fish length spawning at 50 percent (SL50) ranged from 139 mm to 196.29 mm. And then fish length spawning at 95% (SL95) from 160.39 to 243.54 mm). Furthermore, in 2013-2018 monitoring activity SPR relatively low and decrease every year, and first at breeding (50% and 95%) also decrease. It means the gonad maturity and SPR could be used as an indicator of fishing pressure and sustainability.

This study aims to determine the occurrence of helminth endoparasites that infect threadfin bream from Fish Auction Place of Mayangan, Probolinggo, East Java, Indonesia. Helminth endoparasite found in the stomach, intestine (mucosa), and threadfin bream’s liver were third-stage larvae of Anisakis simplex type I. The prevalence of Anisakis simplex infected threadfin bream in sizes 10-16 cm was 5.71% and in sizes 17-25 cm was 17.1%. The differences in the prevalence of threadfin bream endoparasites in different sizes did not show a significant difference.

Nemipterus japonicus is one of the fish that caught in Blimbingsari Waters, Banyuwangi. This research aimed to determine the food composition of N. japonicus. Descriptive method was used in this study. Collecting data by survey and observation was taken out on Juli-August 2018. The samples were collected from fisherman at Blimbingsari. Data analysis used Index of Preponderance (IP). The results showed that the main food of the N. japonicus was shrimp (IP 62.55%), the complementary food was crab (IP 26.03%) and squid (IP 5.92%), the supplementary food was brittle star (IP 2.37%) and fish (IP 2.85%). Based on the composition of the food, N. japonicus was a type of carnivorous.

Because of its importance as a food source, Nemipterus japonicus (Bloch, 1791) (Nemipteridae) or Japanese threadfin bream is the best studied of these taxa, and numerous investigations have examined its fisheries, its biology and biochemistry. Despite such intensive work, the taxonomic status of N. japonicus has never been seriously questioned and it is regarded as a common species, widely distributed throughout the Indo-Western Pacific Ocean. In fact, Bloch’s description of the type specimen of N. japonicus has ambiguous collection data and lacks a designation for the type locality, though it is probably Java. In this paper, DNA barcode results based on COI gene support the existence of two geographically separated lineages of the Japanese threadfin bream, both being an Indian Ocean and western Pacific lineage, with 2.7% sequence divergence, and the results indicate a possible existing of some cryptic species. The two lineages also possess a diagnostic difference in their belly color, with specimens in the South China Sea having a silver belly, while those from the Indian Ocean isolate specimen have a yellow coloration. Based upon new collections from the South China Sea, this species from the western Pacific is morphologically redescribed and its details of DNA barcode diversity are shown for the future investigations.

The reproductive biology of Nemipterus japonicus (Bloch, 1791) along the north-east coast of India was studied during 2012-2015 based on samples from the trawl landings at Digha, Paradeep, Visakhapatnam and Kakinada. Adults dominated the landings. Significant contribution by females was observed in most months of the year. Size at first maturity for females was 15.1 cm. Peak spawning season was during August to February and September to March in the northern and southern regions. Maturity and gonado-somatic index (GSI) were found to correlate well with sea surface temperature (SST). Fecundity increased with length and weight and varied from 13,176 to 1,30,798. Ova diameter distribution indicated the species to be a multiple/batch spawner.

Japanese threadfin bream Nemipterus japonicus (Bloch, 1791) is among the most abundant and commercially important species in Pakistan. From the coast of Pakistan, four demersal trawl surveys in October–November 2009 and May–June, August, October and November in 2010 were carried out. The purpose of this study is to estimate the population dynamics and status of the stock of the N. japonicus from Pakistani waters based on the research trawl surveys from the research area. The data consist of n=784 length-weight pairs and n=7 530 length frequency with the maximum length and weight of 29 cm and 358 g respectively. The length frequency data were analyzed using ELEFAN method in FiSAT computer package. The parameters of length and weight relationship were b=2.778, a=0.032 and R 2=0.973. The estimated von Bertalanffy growth function parameters were L ∞=30.45 cm, K=0.270 year−1. Based on length-converted catch curve analysis the total mortality (Z) during this study was estimated at 0.960 year−1. The natural mortality coefficient (M) was 0.74 year−1 using Pauly’s equation (the annual average sea surface temperature was 27°C), therefore, the fishing mortality coefficients (F) were 0.22 year−1. The yield per recruit analysis indicated that when t c was 2, F max was estimated at 1.2 and F 0.1 at 1.1. When t c was 1, F max was estimated at 0.95 and F 0.1 at 0.8. Because current age at first capture is about 1 year and F current was 0.22, F current is smaller than F 0.1 and F max, which indicated that the fishery is about in a safe condition. When using Gulland (1971) biological reference point, F opt was equals to M (0.74). The current fishing mortality rate of 0.22 was smaller than the target biological reference point.

The utilization of waste from fish processing industry for production of value added products has attracted substantial attention. Tiger-toothed croaker ( Otolithes ruber ) and Pink perch ( Nemipterus japonicus ) are used for surimi production and have the potential of abundant supply of raw skins and bones. In order to evaluate the waste from Tiger-toothed croaker and Pink perch as a source of gelatin, the gelatin was extracted from skin and bones and its rheological and functional properties were examined. The skins of Tiger-toothed croaker and Pink perch yielded 7.56% and 5.57% gelatin, whereas their bones yielded 4.57% and 3.55% respectively indicating skin as an important source for gelatin production. The gel strength of gelatins from the skins and bones of Tiger-toothed croaker (170 g and 140 g respectively) were found higher than Pink perch skin and bone gelatins (150 g and 130 g respectively). Similarly, the viscosity, melting point, emulsifying capacity and stability, foaming capacity and stability, and water holding capacity of gelatin extracted from Tiger-toothed croaker were in general greater than those of the gelatin from Pink perch and the values of skin gelatin were higher compared to bone gelatin in both the species. Hydroxyproline contents in skin and bone of Tiger-toothed croaker were 7.77 and 7.51 mg/g and in Pink perch they were 7.63 and 7.41 mg/g respectively. It can be concluded from the present study that Tiger-toothed croaker skin is a prospective source to produce gelatin in good yield with desirable functional properties comparable to commercially available mammalian gelatins.

Trophic interactions in commercially exploited demersal finfishes in the southeastern Arabian Sea of India were studied to understand trophic organization with emphasis on ontogenic diet shifts within the marine food web. In total, the contents of 4716 stomachs were examined from which 78 prey items were identified. Crustaceans and fishes were the major prey groups to most of the fishes. Based on cluster analysis of predator feeding similarities and ontogenic diet shift within each predator, four major trophic guilds and many sub-guilds were identified. The first guild ‘detritus feeders’ included all size groups of Cynoglossus macrostomus , Pampus argenteus , Leiognathus bindus and Priacanthus hamrur . Guild two, named ‘Shrimp feeders’, was the largest guild identified and included all size groups of Rhynchobatus djiddensis and Nemipterus mesoprion , medium and large Nemipterus japonicus , P. hamrur and Grammoplites suppositus , small and medium Otolithes cuvieri and small Lactarius lactarius . Guild three, named ‘crab and squilla feeders’, consisted of few predators. The fourth trophic guild, ‘piscivores’, was mainly made up of larger size groups of all predators and all size groups of Pseudorhombus arsius and Carcharhinus limbatus . The mean diet breadth and mean trophic level showed strong correlation with ontogenic diet shift. The mean trophic level varied from 2.2 ± 0.1 in large L. bindus to 4.6 ± 0.2 in large Epinephelus diacanthus and the diet breadth from 1.4 ± 0.3 in medium P. argenteus to 8.3 ± 0.2 in medium N. japonicus . Overall, the present study showed that predators in the ecosystem have a strong feeding preference for the sergestid shrimp Acetes indicus , penaeid shrimps, epibenthic crabs and detritus.

A total of 30 specimens (73–95 mm standard length) of Nemipterus randalli were collected along the Lebanon coast. This species, a Lessepsian migrant previously misidentified as Nemipterus japonicus, appears to be well established in the Levantine basin of the Mediterranean Sea. The small size and immature status of the specimens of N. randalli collected from the Lebanon coast indicate recent successful recruitment.

This paper reports the length-weight relationships and morphological characters of three fishes namely, Polydactylus sextarius , Nemipterus japonicus and Pampus argenteus , collected from the Fiery Cross Reef (9 o 37’ N, 112 o 58’ E) of South China Sea during November 2013. The length-weight relationships of the studied fishes can be expressed as W Po = 1.17 L 1.46 for P. sextarius, W Ne = 0.07 L 2.73 for N. japonicus and W Pa = 0.04 L 3.05 for P. argenteus . Growth of P. argenteus was found to be positive ( b > 3) and N. japonicus ( b = 2.73) was negative allometric. Body length of P. sextarius varied from 100.36 to 119.43 mm , and the wet weight ranged from 10.04 to 45.42 g. Body length of N. japonicus varied from 88.37 to 159.54 mm, wet weight ranged from 22.42 to 128.39 g. Body length of P. argenteus varied from 75.13 to 92.07 mm, and wet weight ranged from 20.58 to 42.27 g. The study provides first biological reference in these species in Fiery Cross Reef, South China Sea. In addition, the results of the present study will offer fundamental information for resource assessment as well as for taking up further aquaculture practices of these three species.

Summary The spawning periods, sex ratio and length at first maturity were determined for six commercially important finfish species collected from Oman's industrial trawl fishery. During 1 year of monthly sampling, biological data were collected on 5586 fish. ancova was used to compare the length–weight relationships between sexes. There were sex-specific differences in length-weight relationships for three of the six species examined. One serranid, Epinephelus diacanthus, and a sparid, Pagellus affinis, had sex ratios significantly different from the expected ratio of 1 : 1. Size–frequency data revealed more male fish in the larger size classes for E. diacanthus, P. affinis and Nemipterus japonicus. Data on the development of female gonads and Gonado-somatic Index (GSI) revealed that the six species spawned at different times of the year. With the exception of female E. diacanthus, all fish had low GSI values during the onset of the summer monsoon period in June. The proportion of immature vs mature fish in the sample differed among species. For two species, Lethrinus nebulosus and Cheimerius nufar, more than 40% of the fish sampled (both sexes) were immature. Approximately 33% female and 41% male P. affinis were also immature. Management options such as temporal and area closures are discussed in light of the large number of immature fish caught by the fishery.

A specimen of the Japanese threadfin bream Nemipterus japonicus was recorded for the first time from the Mediterranean Sea. The presence of this Indo-Pacific fish in the Mediterranean is evidently due to migration from the Red Sea via the Suez Canal.

An investigation lasting 36 weeks was carried out on the frozen storage ( - 20C) behavior of surimi prepared from the fish pink perch ( Nemipterus japonicus ). Total volatile base nitrogen (TVBN), trimethylamine (TMA), peroxide value (PV) and total plate count (TPC) values of surimi increased gradually from 3.5 ± 0.1 to 5.60 ± 0.17 mg%, 0 to 2.8 ± 0.2 mg%, 0 to 0.8 ± 0.3 meq/kg and 5.25 ¥ 10 4 to 9.58 ¥ 10 4 cfu/g, respectively, during frozen storage but were within the acceptable limit. Nonprotein nitrogen (NPN), free alpha-amino nitrogen and surimi whiteness increased from 13.63 ± 0.09 to 22.35 ± 0.2 mg%, 0 to 8.55 ± 0.02 mg% and 61.83 to 63.48 degrees, respectively, with the passage of time. Moisture, crude protein, total nitrogen (TN), pH and gel strength of surimi decreased from 78.50 ± 0.14 to 76.55 ± 0.02%, 17.72 ± 0.18 to 14.57 ± 0.01%, 2.84 ± 0.02 to 2.14 ± 0.02%, 7.20 ± 0.1 to 6.05 ± 0.09, and 237 to 97.43 g ¥ cm, respectively, during frozen storage. The surimi was acceptable at the end of the 36 week storage period.

Six commercially important species of fish, i.e. mackerel (Rastrelliger kanagurta), sardine (Sardinella fimbriata), emperor bream (Lethrinus miniatus), threadfin bream (Nemipterus japonicus), trevally (Carangoides armatus) and barracuda (Sphyraena barracuda) of the Thoothukkudi coast of Tamil Nadu, India, were examined for changes in histamine and volatile amines (TVB-N and TMA-N) under ambient temperature storage (32±2 °C). Fish were organoleptically acceptable up to 15 h of storage, except emperor bream that spoiled after 12 h of storage. Histamine and volatile amines increased progressively on storage, but the rate of change varied with the species of fish. The TVB-N content of barracuda and emperor bream exceeded the acceptable limit of 35 mg/100 g after 15 h of storage while, in other fishes, their formation was slow. However, the TMA-N contents of all the fishes were above 10 mg/100 g after 15 h of storage. The TMA-N content of fish was found to correlate more closely with the sensory changes than the TVB-N content. With regard to the histamine toxicity, the histamine content was above the USFDA maximum allowable limit of 50 ppm in mackerel after 12 h, and, in sardine and trevally, after 15 h of storage. The histamine content did not show any correlation with the sensory changes or with the content of volatile amines. In trevally, it was noted that the histamine formation was very high and similar to that of mackerel. It is therefore concluded that the mackerel, sardine and trevally could cause histamine toxicity problems before they become organoleptically unacceptable.

Catch rates and sizes of Saurida undosquamis and Nemipterus japonicus were more variable during daytime. But, Pomadasys stridens were more variable in night tows. Catch rates of S. undosquamis and N. japonicus were higher during daytime and of significantly small mean fish size. Inversely, P. stridens had significant higher catch rates and the fish caught were smaller in night tows. Variability of catch rate and size of Penaeus semisulcatus and Penaeus japonicus was higher at night. Daytime catch rates were significantly lower and of smaller mean shrimp size. Penaeus latisulcatus was available only at night.

Based on light and scanning electron microscopy, one new species of philometrid nematodes, Philometra damriyasai sp. nov. (Nematoda: Dracunculoidea: Philometridae) from the body cavity of Tylerius spinosissimus (Regan, 1908) (Tetraodontiformes, Tetraodontidae), and five known species are reported in different marine teleosts from South Bali, Indonesia. The new species can be distinguished from the most closely related P. javensis Moravec, Walter & Juniar, 2012 by the absence of sclerotized denticles on the cuticle of the anterior oesophageal lobes of the mouth and smaller larvae. Philometra nemipteri Luo, 2001 of Nemipterus japonicus (Bloch, 1791), P. otolithi Moravec & Manoharan, 2013 of Otolithes ruber (Bloch & Schneider, 1801) (both from gonads) and Philometroides marinus Moravec & Buron, 2009 from the body cavity of Rachycentron canadum (Linnaeus, 1766) are reported for the first time from Indonesian waters, thus extending their range of distribution into the tropical Indo-Pacific Ocean. Philometra lobotidis Moravec, Walter & Yuniar, 2012 from the body cavity of Lobotes surinamensis (Bloch, 1790) and P. ocularis Moravec, Ogawa, Suzuki, Miyaki & Donai, 2002 from the eye cavity of Variola louti (Forsskål, 1775) represent new geographical records, and Philometra sp. was recorded for the first time from Cephalopholis sexmaculata (Rüppell, 1830). A total of 14 philometrids have been so far identified from marine fishes in Indonesia.

Fresh, eviscerated threadfin bream (Nemipterus japonicus) packaged in polyethylene pouches were dipped in 10% (w/w) sodium chloride for 1 h and subjected to gamma irradiation at 0, 1 or 2 kGy at ice temperature. The treated fish were stored under ice. At periodic intervals, quality of the fish was determined by sensory, chemical and microbiological parameters. The unsalted and unirradiated fish was acceptable up to 8 days in comparison to a storage life of 12 and 22 days for the unsalted fish irradiated at 1 and 2 kGy, respectively. Salting prior to irradiation at 0, 1 or 2 kGy gave a shelf life of 9, 14 and 28 days, respectively. Salting gave a firmer texture to the fish and prevented drip formation in the pouches during storage. The results suggested that while irradiation could significantly (P

Summary Weight–length relationships were estimated for 20 Lessepsian fish species of the Iskenderun Bay, namely, Apogon nigripinnis, Apogon queketti, Callionymus flamentosus, Cynoglossus sinusarabici, Dussumieria elopsoides, Etrumeus teres, Fistularia commersonii, Lagocephalus spadiceus, Lagocephalus suezensis, Leiognathus kluzingeri, Nemipterus japonicus, Oxyurichthys petersenii, Saurida undosquamis, Sillago sihama, Siganus luridus, Siganus rivulatus, Sphyraena chroysotaeina, Stephanolepis diaspros, Upeneus moluccensis and Upeneus pori. All regressions were found to be significant for all species. This study presents the first estimation of weight–length relationships for six species (A. queketti, E. teres,F. commersonii, L. suezensis, Nemipterus randalli, and S. luridus) inhabiting coastal areas of the northeastern Mediterranean Sea.

Ice storage of dressed pink perch (Nemipterus japonicus) and Indian oil sardine (Sardinella longiceps) for 16 and 20 days, respectively, resulted in a decrease in emulsifying capacity (EC), protein solubility (PS), relative viscosity (RV) of salt-soluble proteins (SSP) and water-soluble proteins (WSP), water binding capacity (WBC) in terms of absorbed moisture in water (AM w ), absorbed moisture in brine (AM b ), retained moisture in water (RM w ) and retained moisture in brine (RM b ), WSP and SSP, and increase in cook loss (CL). Decrease in protein solubility influenced the EC, RV, CL and WBC in both the species of fish. Significant (P < 0.05) correlations existed among various functional properties analysed, in both the fishes during the ice storage.

Three parasitic copepods (Siphonostomatoida) belonging to three different genera were recovered from marine fishes of Iraq, and are listed here as new records. The sea lice Caligus epinepheli Yamaguti, 1936 (Caligidae) was collected from the Japanese threadfin bream, Nemipterus japonicus (Bloch). It had been frequently reported from teleost fishes around the world. The second record, comprising male and female, was another caligid, rarely caught from fishes — Hermilius longicornis Bassett-Smith, 1898, collected from the giant catfish, Netuma thalassina (Rüppell). This paper features the first description of the male of the latter species. The third record was the lernanthropid, Lernanthropinus temminckii (von Nordmann, 1864) (Lernanthropidae), redescribed based on the specimens collected from the greater lizard fish, Saurida tumbil (Bloch) (Synodontidae). In order to clarify its taxonomic status, our specimen was compared with the holotype of L. gibbosus (Pillai, 1964) from the collections of Zoological Survey of India, Kolkata, and the syntypes of L. sauridae Do in Ho and Do, 1985 and L. temminckii from the collections of the Smithsonian Institution, Washington D.C. We found similarities in the morphology of the body, mouthparts, and legs 1–4 in three above-mentioned species. The prominent feature, the setation pattern of legs 1 and 2 was similar in all the female specimens examined. In the light of this, we formally relegate L. gibbosus and L. sauridae to synonymy with L. temminckii. Another important similarity is that Lernanthropinus gibbosus, L. sauridae, and L. temminckii have exclusively been parasitic on lizardfishes (Synodontidae). The attachment site of all three copepods reported form Iraq were the gill filaments.

This study reports the Length-weights relationships, and relative weights of 5 demersal fish species of Persian Gulf. Specimens were caught during fishing surveys using different types of fishing gears between April 2008 to December 2010. A total of 653 individuals were sampled. The parameter b ranged between 2.626 (Acanthopagrus latus (Houttuyn, 1782)) to 2.995 (Carangoides talamparoides (Bleeker, 1852)). The coefficient of determination (r2) was very significant for all the species. Relative weight differed significantly (Kruskal-Wallis test, P< 0.001) with best performance by Saurida tumbil (Bloch, 1975) and Nemipterus japonicus (Bloch, 1791). Otolithes ruber (Bloch and Schneider, 1801) showed 90% mean weight calculated for this species. To the authors’ knowledge, the length-weight relationships and the Relative weights presented for N. japonicus, C. talamparoides and S. tumbil are reported for the first time from the Persian Gulf, but A. latus and O. ruber have not been previously reported for the Iranian water fishes. Key words: Persian Gulf, length-weights relationships, relative weights, demersal fish species.

The complete mitochondrial sequence of the Japanese threadfin bream, Nemipterus japonicus has been determined. The circle genome is 16,995 bp in size, and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The gene order and composition of N. japonicus was similar to that of most other teleosts. The base composition of H-strand is 28.11% (A), 28.02% (T), 16.64 % (G) and 27.24 % (C), with an AT content of 56.12%. All genes are encoded on the heavy strand with the exception of ND6 and eight tRNA genes. The mitochondrial genome of N. japonicus presented will be in favor of resolving phylogenetic relationships within the family Nemipteridae and the Perciformes.

The body burdens of environmentally persistent chlorinated insecticides such as DDT and its metabolites and HCH (BHC) isomers in 14 species of marine fishes collected from Tamil Nadu (Madras, Cuddalore, Nagapattinam and Tuticorin) and Pondicherry coasts of Bay of Bengal in South India were reported. The total HCH was more dominant than total DDT. Moreover α-HCH and p , p ′-DDT were greater among HCHs and DDTs respectively. Higher concentrations of both the compounds were detected in the tissues of rays ( Dasyatis sp.), Lates calcarifer, Scomberomorus guttatus and Nemipterus japonicus .

Surimi was prepared from barracuda ( Sphyraena sp. ), tilapia ( Oreochromis mossambicus ), threadfin bream ( Nemipterus japonicus ) and prawns ( Metapenaeus dobsoni ). Washing for 2 min with a mince-to-water ratio of 1:2 and a second washing for 2 min at the same ratio was optimum for barracuda, tilapia and threadfin bream. Washing for 1 min at a mince-to-water ratio of 1:1 was optimum in the case of prawns. Gels from unwashed mince were firmer and less elastic than those from washed mince, which were soft and flexible. Addition of 2% (w/w) NaCl and 2% (w/w) corn starch to the surimi increased its firmness and toughness. The losses of total nitrogen during different washing cycles are presented. Functional characteristics of the surimi measured by their compressibility and water holding capacity are also given.

This communication gives data on the content of 10 trace metals in six commercially important fish species from the Arabian Sea.

Morphometric comparison of the samples ofNemipterus japonicas populations from four different localities on the east coast of India is made. Analysis of covariance of morphometric characters reveals significance at 1% level for three characters. Character by character comparison of the means of locality-samples shows that there is clinal gradation in maxillary length (south to north) and pectoral length (north to south). The distance function (D)2 analysis shows that Kakinada is the farthest removed from other localities, and Visakhapatnam and Madras samples are nearer to each other. Paradeep sample occupied an intermediate position among the locality-samples. It is concluded that allNemipterus japonicus populations along the east coast of India are from a single genetic population, with restricted and localized movements confined to the areas where they are caught. The observed distinctness of Kakinada sample appears to be due to phenotypic variation under the influence of low salinity.

The rate of fish invasion into the Mediterranean Sea has increased in recent decades; col- lectively they have significant ecological and economic impacts in the eastern Mediterranean. One of this species is Japanese thread fin bream Nemipterus japonicus that gradually get abundance in the Egyptian Mediterranean coast bottom trawl catch. During 2011, monthly samples of N. japonicus caught off Abu Qir area, Alexandria-Egypt, were used to estimate some biological parameters of this immigrant species. Females were more in abundance than male in the catch deviated to smaller size than male. Spawning season extended from April to November with highest activities in July. Maximum observed age was 3 years for both sexes with no significant difference between their lengths at age. Length-at-age was fitted to the Von Bertalanffy growth models. Present results of the Mediter- ranean Sea population showed lower biological (e.g. growth and longevity) condition comparing to original indo-pacific population. a 2014 Production and hosting by Elsevier B.V. on behalf of National Institute of Oceanography and Fisheries.
