Effect of food fatty acid and sterol quality on Pecten maximus gonad composition and reproduction process

Spawning individuals of the scallop Pecten maximus were conditioned on three test diets: Tahiti Isochrysis, a mixture (PTSC) and Chaetoceros calcitrans. The scallops fed T-Isochrysis showed a better hatching rate and lower atresia than those fed the other two diets.
