Hatchery broodstock conditioning of the blue mussel Mytilus edulis (Linnaeus, 1758), part II: new formulated feeds offer new perspectives to commercial hatcheries
Five diets were compared for their efficiency at maturing the gonads of the blue mussel, Mytilus edulis. The diets consisted of a 1:1:1 mixture of Isochrysis galbana (T-Iso), Pavlova lutheri, and Chaetoceros calcitrans given at concentrations of 2.4 x 10(11) cells day(-1) for the positive control tr...
