Název v původním jazyce

Diet and growth of 1+ Siberian sturgeon, Acipenser baerii in alternative pond culture

Popis výsledku v původním jazyce

The culture of 1+ Siberian sturgeon (Acipenser baerii) was performed in concrete storage ponds with natural water temperature regime during the growing season. Fish were separated into two groups ? with supplementary feeding using trout pellets (FF) andcontrol variant (CF). Specific growth rates in FF and CF were 0.26 and 0.16%.day-1 in length and 0.53 and 0.18%.day-1 in weight, respectively. The average indices of weight condition rose from initial 0.377 and 0.372 to final values of 0,393 and 0,322 inFF and CF, respectively. Fish diet consisted of 25 food items. Chironomid larvae, cladocerans (Daphnia sp.) and detritus prevailed in fish guts with 40.4 ? 52.8, 19.1 - 28.8 and 16.3 ? 19.4%, respectively. Pelleted feed occurred in 8.7% proportion in one third of examined FF fish. The index of preponderance for artificial feed was only 3.53; however its role in the growth performance and condition of Siberian sturgeon in pond culture was very important.
