Pacific oyster physiology data with different microalgal diets 2020-2022

72 adult Pacific oysters collected from Woolston bay in Southampton in October 2021 and fed one of three microalgal diets: Isochrysis galbana, Nannochloropsis gaditana/oculata, or an equal mix of Isochrysis and Nannochloropsis. Data include total weight, shell weight, internal tissue weight, respiration rate, and expression levels of four shell-forming genes for all oysters. Stable isotope (SI) composition of the Isochrysis galbana and Nannochloropsis gaditana were measured, as was the SI of the stomach of oysters fed the mixed species diet.
