Cornstarch as a dietary supplement in conditioning broodstock and spat at a nursery of the Pacific calico scallop, Argopecten ventricosus

ABSTRACT Microalgae diets supplemented with cornstarch at a rate of 0.15% of live weight to the conditioning of broodstock and spat growth of Pacific calico scallop Argopecten ventricosus were tested. To determine reproductive condition at the beginning and end of the experiment, the gonads of adult...

To determine reproductive condition at the beginning and end of the experiment, the gonads of adults were analyzed by stereological methods.

The microalgae diet of Tisochrysis lutea and Chaetoceros calcitrans, supplemented with cornstarch, substantially improved the reproductive status of the scallop, particularly by increasing the number of individuals in mature and mature-spawning stages with more mature oocytes by the scallop.
