Based on our research and surveys conducted among amateur fishers the composition of Ichthyofauna in Spendaryan Reservoir is presented, as well as the morphological characteristics of Scrapper Capoeta capoeta and Crucian carp Carassius gibelio, which are the main objects of amateur fishing, are described. The main factors having a negative impact on the Ichthyofauna of Spandaryan Reservoir have been identified, which was taken into consideration to propose increasing the fish productivity of Spandaryan Reservoir by importing and breeding more economically valuable fish species, thus contributing to the sustainable socio-economic development of rural communities.

We present a critical checklist of freshwater fish species found so far in the countries of Armenia, Azerbaijan and Georgia. In total 119 freshwater fishes are recorded. There are 40, 86 and 96 species currently known for Armenia, Azerbaijan and Georgia respectively. From these 119 species, seven are endemic and seven species are alien. From the alien species, only three (Carassius gibelio, Gambusia holbrooki and Pseudorasbora parva) can be considered as widespread and invasive. There are four species (Gasterosteus aculeatus, Gobio artvinicus, Perca fluviatilis and Salmo gegarkuni) that are translocated within the region. Seven species are confirmed or recorded for the first time including G. artvinicus and Oxynoemacheilus veyselorum for Armenia, Azerbaijan and Georgia, Capoeta kaput and Rhinogobius lindbergi for Azerbaijan and Georgia, Capoeta razii for Azebaijan, Oxynoemacheilus cemali and Squalius agdamicus for Georgia. In this checklist, Acipenser colchicus is treated as a synonym of Acipenserpersicus. Sand smelts of the Black and Caspian Sea basin are identified as Atherina caspia and Clupeonella caspia is treated as a synonym of Clupeonella cultriventris. Coregonus sevanicus is listed as Coregonus sp. until the situation of Sevan whitefish is better understood. Capoeta sevangi and Capoetaekmekciae are synonyms of Capoetacapoeta. The fish often identified as Capoeta capoeta gracilis from rivers south of the Kura most likely belong to C. razii. The Black and Caspian Sea Rutilus populations are treated as conspecific, therefore R. kutum is a junior synonym of R. frisii. Oxynoemacheilus veyseli is valid as O. veyselorum. We list the alien Rhinogobius species as R. lindbergi, however the name is provisional and needs further confirmation. All Squalius species from the Kura River drainage are identified as S. agdamicus, however in the Aras, it is replaced by S. turcicus. Squalius orientalis is treated as a valid species restricted to the eastern Black Sea basin. The four forms of Lake Sevan trout (Salmo ischchan, S. gegarkuni, S. danilewskii and S. aestivalis) are treated as valid species, two of them (S. ischchan and S. danilewskii) are extinct. Rutilus sojuchbulagi from Azerbaijan is also extinct. [ABSTRACT FROM AUTHOR]

The article touches upon the morphological characteristics of Crucian carp Carassius gibelio (Bloch, 1782), Kura chub Alburnoides eichwaldii, Kura nase Chondrostoma cyri, Stone moroko Pseudorasbora parva, Grass carp Ctenopharyngodon idella currently found in the Karnut Reservoir, as well as the extensity and intensity of infection of individual fish species such as Ligula intestinalis with plerocercoid. Based on the conducted studies, it is recommended to increas the fish productivity of the Karnut Reservoir by importing and breeding the most economically valuable fish species, thus contributing to the socio-economic sustainable development of rural communities.

The Ichthyofauna of Joghaz reservoir in Tavush region has been studied for the first time, where 7 species have been identified: Crucian carp, Common carp, Scrapper, Kura bleak, Stone moroko, Golden spined loach registered in RA Red Book of Animals and unidentified type Cobitis. The most numerous types of these species are Crucian carp, Scrapper, Kura bleak and Stone moroko, which, by their external characteristics, are not substantially different from the same species of fish found in the other freshwaters of Armenia.
