Growth, calcium content, proximate composition, and fatty acid composition of triangle sail mussel (Hyriopsis cumingii) fed five different microalgal diets

Abstract Sustainable cultivation of triangle sail mussel Hyriopsis cumingii lacks a suitable, optimal diet. To determine the optimum microalgal diet H. cumingii, we tested five microalgal diets (Cyclotella sp., Chlorella pyrenoidosa, Scenedesmus dimorphus, Monoraphidium contortum, and a mix of these four microalgae) using single factor experiments. We measured body growth, pearl growth, proximate composition, fatty acid composition, and calcium (Ca) content in the mantle and foot of H. cumingii. Overall, diet had significant effects on the growth of H. cumingii (P
