New early feeding strategy using Artemia urmiana (Günther, 1899) and formulated diet for the larviculture of sturgeon species Acipenser persicus (Borodin, 1897) and Huso huso (Linnaeus, 1758)
(2012)- abstract
- In this PhD study, we investigated the use of newly hatched A. urmiana enriched with HUFA and vitamin C to improve the growth, survival and stress tolerance in Persian Sturgeon (A. persicus) and Beluga Sturgeon (H. huso) larvae. We also introduced a new feeding strategy for A. persicus and H. huso larvae by co-feeding with Artemia nauplii and locally available formulated diet at early stages of life to help the industry in reducing the production costs and minimize the mortality rate in grow-out ponds. The experiments showed a significantly higher survival and tolerance towards environmental shocks in both fish larvae enriched with HUFA and vitamin C compared to non-enriched and decapsulated cysts treatments. Very high mortality due to feeding with decapsulated cysts of Artemia proved that it is not suitable starter diet for both fish species. We also found that live food co-fed with a formulated diet could be successfully used in early larval feeding of H. huso and A. persicus. The results revealed that co-feeding permits weaning of both species of sturgeon in a shorter time and considerable reduction of rearing costs, but different transition regimes need to be adopted. Analysis of digestive enzymes in A. persicus revealed highest enzymatic activity (alkaline protease and pepsin) in the co-fed larvae, which indicates a better development of the digestive system Co-feeding in both species thus pre-conditions the larvae to accept the manufactured diet when the live food is withdrawn.
