Energy storage and utilization in relation to gametogenesis ofArgopecten ventricosus

摘要

A laboratory study was carried out to observe changes in reproduction of Argopecten ventricosus by using histological techniques in gonads and chemical analysis of digestive gland, adductor muscle, mantle-gills and gonad. These data allowed us to calculate energy storage related to gametogenesis of A. ventricosus. During 66 days, combinations of monocultures (50:50) of C-ISO and CH-1 were added daily to a tank with filtered and aerated seawater. Salinity and temperature of the water were measured with a salinity-temperature probe meter (YSI). Phytoplankton densities were recorded by direct count with a hematocytometer. This study is a contribution to the reproductive biology of A. ventricosus and fisheries management of the tropical scallop.
