摘要
研究低温下栉孔扇贝 (Chlamysfarreri)摄食、呼吸代谢、排泄及能量分配情况 ,为栉孔扇贝的反季节养殖提供生物学依据。在实验室条件下采用静水法 ,测定 3、5和 8℃时栉孔扇贝的能量收支。结果显示 ,在 3～ 8℃时 ,栉孔扇贝的耗氧率、排氨率、摄食率及生长率 (净生长率、毛生长率 )随温度的升高而增大 ;3℃时 ,栉孔扇贝虽然能摄食 ,但是生长率却很低 ;温度对能量分配影响较大 ,生长、排泄分配率随温度的升高而增大 ,呼吸、排粪的分配率与温度呈负相关。在能量收支方程中 ,生长能所占比例变化较大 ,为 17.61%～ 5 3 .2 7% ,代谢能为 2 1.4 8%～3 5 .91% ,排粪能为 2 2 .5 2 %～ 4 5 .99% ,排泄能所占的比例最小 ,低于 3 %。
An indoor static system was employed to study the ingestion rate and energy budget of scallop Chlamys farreri at the water temperatures of 3 ℃, 5 ℃ and 8 ℃, with the scallop shell height (5.48±0.11) cm and individual dry tissue weight (1.182±0.0695) g. The results show that the oxygen consumption rate, the ammonia excretion rate and the ingestion rate all increase with temperature increasing in the range of 3～8 ℃. The water temperature has positive influence on the growth rate(K 1 and K 2) of the scallop. Though the scallop can feed at 3 ℃, the growth rate is low. Also, the water temperature has great effects on the ratios of energy distribution that with the temperature increasing, the growth and excretion rates increase but the respiration and ejection decrease. In the equations erected on the energy budget of the scallop, the ratios of growth, respiration, ejection and excretion make up 17.6%-53.27%, 21.48%-35.91%, 22.52%-45.99% and <3% of the total energy, respectively. The purpose of this study is to research the possibility of C. ferreri culture in opposed seasons.
