Stable isotope analysis of the contribution of microalgal diets to the growth and rurvival of pacific oyster crassostrea gigas (Thunberg, 1979) larvae.

dc.description.abstractStable carbon and nitrogen isotope analyses were used to evaluate the influence of microalgal diet on growth and survival of hatchery-reared Pacific oysterCrassostrea gigas larvae.D-veliger larvae were fedmonospecific diets of Pavlova lutheri (P), Tahitian Isochrysis aff. galbana (T), and Chaetoceros calcitrans (C), and a standard hatchery trispecific diet of 25P:25T:50C (PTC). The dietary effects on nutrient assimilation, isotopic turnover rates, and discrimination factors were assessed using exponential models. Of the four dietary treatments evaluated over the 15-day feeding trial, larvae fed C. calcitrans and PTC had the best growth and high survival. Larvae in all dietary treatments had relatively high isotopic turnover rates (0.075–0.327/day), although some discrimination factors found in this study were out of the normal range for aquatic invertebrates (Δ13C: 0.4‰–4.1‰ and δ15N: 0.1‰–5.3‰). Overall, the turnover rates and discrimination factors for δ13C and δ15N indicated that C. gigas larvae assimilate C. calcitrans and PTC best under hatchery rearing conditions. The results demonstrated the application potential of stable isotope analysis to evaluate optimal diets and feeding regimes to enhance hatchery performance of bivalve larvae and postlarval stages.© 2016, BioOne.en_AU
