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.

The effect of these diets on oyster physiology was measured using: respirometry to calculate respiration rate, cell clearance and rejection rate by counting algal cell density and pseudofaeces before and after feeds, weight gain (both of the shell and the internal tissues), comparative stable isotopic analysis of the microalgae and the oyster guts, and the expression of four shell-forming genes. Temperature, pH, ammonia, nitrite, nitrate, and dissolved oxygen in the seawater was also measured. MEDIN 3.1.1
