Abstract
    Populations of the Manila clam, Tapes philippinarum, were maintained at temperatures of 12, 15, 18, and 21° C for a period of 19 weeks. Regular determinations were made of ammonia excretion rate following which animals were sacrificed for estimation of dry meat weight, dry shell weight, biochemical composition, and gonadal development. T. philippinarum increased from an initial dry meat weight of 291.5 mg to final values of 957.9, 733.0, 735.0, and 586.0 mg at 12, 15, 18, and 21° C, respectively. An initial increase in percentage carbohydrate content was evident at all temperatures. This was followed by carbohydrate depletion associated with gametogenesis, the transition from accumulation to depletion occurring earlier with increasing temperature. Ripe gonadal material was evident at all temperatures, but spawning was only evident at 15, 18, and 21° C. Ammonia excretion at 12, 15, and 18° C showed an allometric relationship to meat weight; this was not so at 21° C.
