Název v původním jazyce

Combined effect of weaning time and co-feeding duration on growth and survival of peled Coregonus peled (Gmelin) larvae

Popis výsledku v původním jazyce

The study investigated the combined effect of weaning from live feed to a commercial dry pellet at 10, 15, 20, 25 or 30days posthatching (dph) and co-feeding for 1, 3 or 6days on survival and growth of Coregonus peled larvae. Additional groups fed only live Artemia sp. nauplii (ART), and only Biomar LARVIVA ProWean 100 (DRY) were included. A final survival rate of 66.4%-85.5% was observed in groups weaned after 20dph. Final body weight (BW) and total length (TL) were significantly lower in groups weaned at 10 and 15dph, regardless of the duration of co-feeding. Larvae reached 29-37mg BW and TL of 17.7-19.0mm in groups weaned at 20, 25 and 30dph. The recommended minimum duration of feeding with live food, based on these results, is 20days. Based on the significantly higher yield of larvae weaned after 20dph irrespective of co-feeding duration, it can be concluded that abrupt weaning to dry food after 20days of feeding with live prey can provide adequate production while reducing the effort and costs associated with live feed.
