Phylogenetic relationships among five species of Alosa (Alosa maeotica, A. tanaica, A. caspia, A. immaculata and A. fallax nilotica) was examined with sequence analyses of mtDNA ND5/6 region. In pairwise comparision, the highest genetic differences were observed between A. caspia and A. tanaica (0.691), and lowest between A. maeotica and A. tanaica (0.491). In minimum evolution tree, two phylog...

Climate change and invasive species can both have negative impacts on native species diversity. Additionally, climate change has the potential to favor invasive species over natives, dealing a double blow to native biodiversity. It is, therefore, vital to determine how changing climate conditions are directly linked to demographic rates and population growth of non-native species so we can quan...

Common kilka Clupeonella cultriventris (Nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the Caspian Sea. A total of 60 specimens of adult common kilka were sampled from two seasons. Fifteen pairs of microsatellites previously developed for A.sapidissima, C. pallasi, C.harengus, and S. pilchardus were tested for ...

changes in the fatty acid content, during frozen storage at -24°c of caspian kutum (rutilus frisii kutum), golden grey mullet (liza aurata), common carp (caprinus carpio), pike perch (sander lucioperca) and common kilka (clupeonella cultiventris caspia), caught from south caspian sea were studied in the present work. changes in saturated fatty acids (sfas), monounsaturated fatty acids (mufas), ...

  The aim of the present study was to investigate the age structure, length-weight relationship, sex ratio, sexual maturity stages, growth parameters, natural and fishing mortality coefficients of three species of kilka including common, anchovy and bigeye kilka. The fork length–weight relationship of common, anchovy and bigeye kilka were calculated as W=0.000153 FL2.37, W=0.000349 FL2.18 and W...
