Kapal perikanan di Indonesia khususnya kapal penangkap ikan dan kapal pengangkut ikan secara umum dibangun oleh galangan kapal tradisional. Pembangunan kapal yang dilakukan oleh galangan kapal tradisional biasanya tidak dilengkapi dengan perencanaan teknis. Perencanaan teknis dalam pembangunan kapal diantaranya adalah general arrangement, lines plan, construction plan, dan perhitungan hidrostatis dan stabilitas. Biro Klasifikasi Indonesia (BKI) adalah badan klasifikasi nasional yang memiliki wewenang dalam mengatur ukuran konstruksi, cara penyambungan, dan penentuan jenis kayu pada kapal. Berdasarkan hal tersebut, perlu dilakukan kajian terhadap kesesuaian ukuran konstruksi utama kapal dengan aturan BKI. Tujuan penelitian ini adalah menganalisis kesesuaian ukuran konstruksi utama kapal perikanan dengan aturan Biro Klasifikasi Indonesia, dan mendeskripsikan faktor-faktor yang dapat memengaruhi kesesuaian ukuran konstruksi utama kapal perikanan dengan aturan Biro Klasifikasi Indonesia di Beberapa Pelabuhan Perikanan di Pulau Jawa. Metode yang digunakan pada penelitian ini adalah penelitian survei. Ukuran konstruksi kapal dibandingkan dengan ukuran konstruksi berdasarkan aturan BKI. Analisis yang digunakan adalah analisis deskriptif komparatif dan analisis deskriptif. Ukuran konstruksi kapal di beberapa pelabuhan perikanan di pulau Jawa beragam, tergantung pada dimensi utama kapal. Rata-rata ukuran konstruksi 47,68% lebih besar dari standar BKI, 52,16% lebih kecil dari standar BKI, dan 0,19% sesuai dengan standar BKI. Rata-rata tingkat selisih ukuran konstruksi sebesar 9,25% lebih besar dari standar BKI. Konstruksi yang rata-rata ukurannya masih di bawah standar BKI adalah galar balok, galar kim, dan kulit luar.

Lobster is one of the commodities that Indonesia export fisheries worth selling high. The value of selling lobster is affected by type, size, and condition or completeness of her body. Palabuhanratu is one of the centers of the lobster fishery in the South of West Java. Research on condition of fishing lobster in Palabuhanratu was done in April through November 2016 include the type, gender, number, and size (carapace length and weight) and its relationship with regulatory. Observation and measurement of the collecting is done in the lobster that come for each/sold to the warehouse by fisherman and follows directly the activities of catching lobsters. The data already obtained tabulated and analyzed. The results showed that types of lobsters captured fisherman Palabuhanratu are Panulirus ornatus, Panulirus penicillatus, Panulirus versicolor and Panulirus homarus. The majority of lobsters are caught is a kind of lobster P. homarus and P. ornatus and then followed P. penicillatus and P. versicolor. The number of the male for P. homarus, P. versicolor and P. ornatus more than females while the females of P. penicillatus more than males. The majority of the lobster weights less than 300 grams and carapace length less than 8 cm. The body condition of fishing lobster in Palabuhanratu based on the lobster fishery regulations that exist for all types of lobsters is a majority yet decent catch.

The sweeping trammel net (ciker net) is operated by lowering the net in a straight line and then pulling the last end of the net with a ship moving in a full circle where the other end functions as a circular axis (M1 method). An alternative way is for the net to be lowered and then towed by the fishing vessel along two opposing semicircular paths (M2 method). The success of fishermen using this net is determined by the swept area. Therefore, the catch for each net section can vary when using the M1 method but is relatively similar in the M2 method. This study compared the catch per net section from the same sweep axis operated with different towing line paths. The experimental fishing was carried out using 1 ciker net unit consisting of 6 pieces. The catch produced by the two operating methods was significantly different as indicated by t = -3.7852, df = 5, α = 0.05, and p-value = 0.01282. The average catch per section (n = 3) was 21 individuals for M1 operation and 47 individuals for M2 operation. The M1 method produced less catch than the M2 method.

Set net is a fishing gear to set permanently in the fishing ground. Set net othosiami was developed by Center for Fisheries Development Department of Marine and Fisheries (BPPI) Semarang; it had been operated in 2010 at the Gulf Mallasoro, Jeneponto. The data information was collected regarding productivity, compositioning and catching diversity was taken from the catching data in 2011 – 2013. The study aims were to analyze catching trend, catching composition types and catching diversity. This study was conducted on January and February 2014 at the Gulf Mallasoro, Jeneponto. The method was used descriptive method. Based on the data from 2011-2013 on September-October showed a decline catching trend while the amount of cacthing trend consist of 91 species. The pelagic fish has been identified for 31 species and 26 species belongs to demersal fish from 57 species were found. The most dominant fish was Peperek (leiognathus splendens) with 27% of fish’s identification. The diversity index (H’) catching fish period 2011-2013 ranged from 2.61 – 2.74 which regard to moderate category diversity. Furthermore, the value of evenness index (E) was more evenly 0.63 - 0.70 categorical. The dominance index value (D) showed within 0.12 to 0.15 there was no dominant species.

One of the fishery resources that have high economic value are demersal fisheries resources in deep sea waters. The results ofthis study found 22 demersal fish species with high economic value captured by fishermen. The results ofthe study found as many as 22 species, five fish stretcher 5 that can be foundin nearly all areas and fishing season. Five types of fish are: lencam (Lethrinus sp.), kurisi (Etelis spp), kerapu (Ephinephelus sp), red snapper (Lutjanus spp), bubara fish (Caranx sp). The types of fish catches were found spread around the waters of Ambon Island. The potential at Maxsimum sustainable Yield (MSY) of fish grouper (Epinephelus spp) 572.02 with 15.75 tonnes optimum effort trip. The average production of 178.919 tonnes currently. Thus the average utilization rate of groupers currently 31.27% or 68.72% untapped. If it is based on the MSY allowable catch for the fish species is 457.60 tons / year. MSY red snapper (Lutjanus spp) 146.83 wih 2.631 tonnes optimum effort trip. Average production is currently 67.704 tons. Thus the average utilization rate of the red snapper fish is currently 47.47%, or in other words the potential for red snapper untapped 52.52%. If it is based on the MSY allowable catch for the fish species is 117 464 tons / year. MSY bubara fish (Caranx sp) 270.60 tonnes with optimum effort 3630 trip with an average yield of 72.96 tons.

Skipjacks in the western and southern waters of North Maluku Province were caught using pole and line with FADs. Skipjack usually swims near the surface water and tends to be classified as a juvenile skipjack that caught during fishing activities. The study objective was to analyze biological data of skipjack including length weight relationship, growth, length at first maturity/lm and catch size, size composition and gonad maturity. Skipjack samples were caught in the waters of the western (zone A) and southern (zone b) areas of North Maluku Province, from April 2012 until May 2013. The sudy results show the value bof skipjack caught around FADs at zone A and B were similar as b=3. This indicates that the growth of skipjack in both areas was categorized as in isometric pattern. L∞ of skipjack caught at zone A was 75 cm at the age of 56 months and at zone B was 76 cm at the age of 56 months. Lm value skipjack caught in zone A and zone B was obtained by 43 cm, with a range of long-forked skipjack caught in zone A from 26.0 to 72.0 cm, and at zone B from 26- to 71 cm , The gonad maturity at zone A and B, was obtained in the similar stages as maturity stages I, II, III,IV, and V. TKG V of the skipjack caught around FADs zone A is found in March and B in July, so it can be presumed skipjack in two zones throughout the year with peak spawning occurs in March for zone A and B in July.Keywords: Biological base, skipjack, fishery management, North Maluku
