Stable Isotope Analysis of the Contribution of Microalgal Diets to the Growth and Survival of Pacific Oyster Crassostrea gigas (Thunberg, 1979) Larvae
Stable 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 Chaetocero...
