Abstract

The effect of temperature on reproductive maturity of recently spawned penshell broodstock Atrina maura (Sowerby 1835) was studied. Penshells were maintained in an open-flow system and were fed to satiation with a mixture ofmicroalgae. Condition index (tissue wet weight/total wet weight x 100), the rate of maturation, and oocyte quality were followed histologically untilspawning, A scheme of six stages, based on histological preparations, was found best to describe the maturation process in the penshell. Results indicate that penshell maturation must be at low temperatures over two months to obtain high quality oocytes in the hatchery, even though the maturation period can be shortened to half that time at higher temperatures. A reduction of the quality of oocytes is obtained at higher temperatures.
