Four microalgae species (Rhodomonas salina, Thalassiosira weissflogii, Thalassiosira pseudonana and Pavlova lutheri) were evaluated to estimate their potential as food for Ostrea edulis (L.) reproductive conditioning. Best ingestion and absorption were observed with R. salina (3.44 and 1.59 mg g− 1 h− 1, respectively), followed by T. pseudonana (2.75 and 0.98 mg g− 1 h− 1) and P. lutheri (2.40 and 0.91 mg g− 1 h− 1). Oysters fed T. weissflogii exhibited the lowest ingestion and absorption values (1.40 and 0.68 mg g− 1 h− 1). Proximate composition (proteins and carbohydrates) and lipid content (fatty acids and sterols) analysed in four main tissues (gonad, digestive gland, muscle and gills) also differed significantly with diet. Protein ranged from 355 mg... |
