Özet (Çeviri)
In this study, sturgeon and carp which are fresh water species were put in fiberglassstanks. Groups were set up sturgeon and carp breeding as well as polyculture carp andsturgeon mixed .These groups were comparated by their growth performance.Sturgeons were imported from Russia (Krasnodar Fisheries Research Institute) to7XUNH\ 6DSDQFD 5HVHDUFK XQLW RI øVWDQEXO hQLYHUVLW\ LQ -DQXDU\ &DUSV ZHUHtaken from a local carp farmAt the beginning of this study, we had 40 sturgeon which had initial mean body weightof 711,9± 245,3 g and 40 carp which also had initial mean body weight of 560,7±184,9g. Every group had 10 fish. The size of tank?s were 3m. x1,30 m.During the experiment, water temperature was between 4,5-16ºC .At the end of the study, live weight gain were measured and all these values were usedto calculate growth rate and food conversion rate. Group 1 showed the highest weightgain (160,67 g) group 3 (126,35 g), group 4 (118,5 g ), and group 2 ( 84,7 g ) followinggroup (1) respectively.Food conversion rates of the groups, during times with water temperatures higher than15 oC were calculated and found to be 2,9 for group (1), 5,5 for group (2), 5,9 for group(3) and 3,1 for group (4). During lower water temperatures calculated data was nothealty and useful for comparison.The data from the experiments and the results are all given in tables and graphs. Allthese results were compared with the recent experiments which were the basis of thisstudy.
