    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Studying native fishes of Hamadan province have been done in 159 stations from 51 important water resources (wetland, reservoir, spring, river and qanat) using with electric tool, cast-net, seine and gill-net gears from July 2010 to Oct. 2011 and the main aims were species identifying and determining their distribution and abundance in the studied area. In the study, 33411 fish specimens are caught in 257 times of sampling and selected randomly about 8500 individual and laboratory works showed the fish belong to 37 species from 7 families. Cyprinidae with 25, Nemacheilidae with 6 and Sisoridae with 2 species had the most diversity and Cobitidae, Poeciliidae, Salmonidae and Mastacembelidae had only a representative. 31 fish species were native or endemic and 6 species were alien. Fish species existed in all rivers of Ghezelozan and Sirvan sub-basins but there were not any fish in 10 rivers of Ghara-Chai sub-basin and in 6 rivers of Gamasiab sub-basin, too. Also, it was observe 1-3 fish species in 15 rivers, 4-6 fish species in 10 rivers, 7-10 fish species in 5 rivers and more than 10 fish species in 4 main water resources and Gamasiab sub-basin with 32 fish species was the most diversified and Ghezelozan sub-basin with 2 fish species was the least diversified. There were any species to 4 (mostly 1 or 2) fish species in studied qanats in Ghara-Chai and Gamasiab rivers sub-basins. 23 fish species existed in a subbasin, 12 species in 2 sub-basin, Capoeta capoeta in 3 sub-basin and Squalius cephalus in all sub-basins of studied area. Alburnoides nicolausi,Capoeta aculeata and Alburnus mossulensis have had the most frequency. Studying fish abundance showed Oxynoemacheilus argyrogramma with 17.8%, Garra rufa with 12.3%, A. mossulensis with 12.1% and C. aculeata with 10.2 % of total number of caught fish specimens are dominant. S. cephalus, Capoeta damascina, C. aculeata, C. trutta, Chondrostoma regium and A. mossulensis have had sport fishing value but Acanthobrama marmid, Oxynoemacheilus kiabii, Oxynoemacheilus kermanshahensis, Turcinoemacheilus kosswigi, Alburnus caeruleus and Mastacembelus mastacembelus have biodiversity value for being endemic or having limited habitats in Iran.

    A Biological Study of Gammaridae (Amphipoda) In the South Caspian Sea Basin (Iranian water) for Use in Fish Culture (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: A study was conducted to determine , feeding , reproduction in 12 stations in the Caspian Sea basin of Iran including Anzali wetland (lagoon), Ghorigol wetland, Neor lake , south Caspian coastal water (Iranian of shore), and several springs in Alborz mountains In addition sampling of Plankton and physical and chemical factors of the water body were also done in all stations. Special aquariums were designed to test the acclimation of the 7 amphipoda in pond culture. This process was performed from march 2001 to Feb 2003. The finding showed that while reproduction of Gammarus lacustris and Gammarus paricrenatus were only about 3 months , that Gammarus komareki lasted throught the year. From diet studies of intestine content have been showed that there is not a correlation between abundance and diversity of plankton with habitat for all species, except about Pontogarnrnarus maeoticus and P. borceae from Kelachi coast that had a high plankton abundance. Gammarus aequicauda (37.75 ± 31.04) and Obesogammarus acuminatus (49.07 ± 40.4) had the maximum of average eggs production while G. komareki had the lowest clutch sizes with mean about 7-8 eggs. Species tolerance to changes in environmental factors (Physical and chemical variation) were limited in the springs while those off coastal water species and Obesogammarus acuminatus were wider. In aquarium (laboratory) study, it was found that although Gammarus lacustris showed some growth but did not reproduce. Gammarus paricrenatus, in later stage of study, reproduced and grow in length during most experiment period. Although Gammarus komareki survived and a little active life, but was not able to acclimate itself to laboratory condition. The findings showed that four species P. maeoticus, P. borceae, O. acuminatus, and G. aequcauda , seems to be good candidate for acclimation study in warm water fish farms. Their living in the ponds can be enhanced by some limited alteration in substrate structure (P. maeoticus, P. borceae), presence of submerged aquatic plants (O. acuminatus) and higher water salinity (more than 2 ppt) for G. aequcauda..
