Název v původním jazyce

Intensive rearing of the nase Condrostoma nasus (L.) larvae using dry starter feeds and natural diet under controlled conditions

Popis výsledku v původním jazyce

We performed intensive rearing of larvae of the nase Chondrostoma nasus (L.) in a feeding experiment until 21 days from the initiation of exogenous nutrition under labolatory conditions at a temperature 26°C. Two dry starter feeds (a feed for salmonids and a starter feed of the artificial plankton type) differing in the composition of nutrients (50% and 60% of proteins, 12% and 16% of fat, respectively) and natural food (Artemia salina nauplii) were used. Cumulative survival rate, individual weight (w),total length (TL), specific weight growth rate (SWGR), specific length growth rate (SLGR) and condition factor (CF) were assessed. One-way analysis of variance (ANOVA) was used for statistical processing of data. High survival rate 99.3% and the highest(P<0.01) growth rate of nase larvae (TL=22.0 mm, W=69.2 mg) were found when feeding the natural food. The application of dry feed of the artificial plankton type resulted in higher survival (98.8%) and significantly higher (P<0.01) growt
