In this study, the fish species inhabiting Bolaman Stream drains to Black Sea from Fatsa coast (Ordu Province, Turkey) was reported for first time. The study caught out non-periodically by sampling seven stations in between July 2017 and November 2018. Fish samples were captured with an electroshock device. With it determined that fauna of is represented 10 five families (Acheilognothidae, Cypr...

Abstract Introduction The experiment was set to determine the effects of long-term (55-day) use three commercial prebiotics including Saccharomyces cerevisiae –derived β-glucans and one inulin on juvenile vimba (Vimba vimba) reared intensively under controlled conditions. Material Methods Six-month-old fish were fed feed (Control group, n = 90), or same supplemented with 0.02% Leiber Beta-S (BS...

in this study, the diversity and distribution of economical bony fishes in less-than-ten-meter depths, cpue and population features such as total length, weight and age were investigated in the southern part of the caspian sea in 1385-6. sampling was done in five regions: amir abad, larim, izdeh, kheyroud, and nashtarood with gilnet in mesh sizes of 26, 33, 40, 60, 100, and 150 mm. in total, 22...

Abstract The recent expansion of the round goby ( Neogobius melanostomus ) in tributaries lower Danube (Bulgaria) prompted assessing potential negative effects on local fish fauna such as competition for food resources. Diet overlap between and native fishes was analyzed using samples macroinvertebrates collected monthly a one-year period. Significant dietary N. Barbus petenyi , Perca fluviatil...
