영문 초록

Seasonal changes in calorific content of subclan, Mantra veneriformis collected from Kunsan areas was measured in 1994. The amounts of feces from subclaim was high from spring to fall according to temperature rising. Variation of calorific contents in feces was varied by month, but was high in June for 3cm group and in September for 2cm group in general. And it was also showed low in February-March and August. The difference between two groups was higher 1.7 times in 3cm group than in 2cm group. The variation of calorific contents in carcass and viscera of subclaim was similar to those of faces, but the differed by size was not appeared. The energy used for respiration was high in summer and low in winter. The calorific contents of shell was low in February and after June. About 60.4~60.6% of total energy loosed for feces, so that the assimilation rate was 39.4~39.6%.
