摘　　要：根据室内流水实验法,定量研究了黄、渤海生态系统7种鱼类能量收支组分,并建立了相应的生物能量学模式。7种海洋鱼类的生物能量学模式显著不同,并可分为3类:(1)较低代谢和较高生长,如黑、矛尾虎鱼;(2)较高代谢和较低生长,如欧氏六线鱼和黑鲷;(3)代谢和生长均处于中等水平,如真鲷、红鳍东方和鲐。其差异原因可能与这7种海洋鱼类的生态习性不同相关。与淡水肉食性鱼类比较,7种海洋鱼类的代谢能明显偏高,表明海洋鱼类属于高代谢消耗、低生长效率型鱼类。Based on flow-through method under the laboratory conditions, the energy budgets were measured and the bioenergetics models were described for seven species of fish distributed in the Bohai Sea and Yellow Sea ecosystem. As a result, the patterns of energy allocation for these seven species of marine fish can be classed into three categories: (1) lower metabolic consumption and higher growth efficiency, e.g. Schlegel's black rockfish and finespot goby; (2) higher metabolic consumption and lower growth efficiency, e.g. black porgy and fat greenling; (3) both metabolic consumption and growth efficiency in medium level, e.g. red seabream, tiger puffer and chub mackerel. The significant difference of energy budgets in these seven species of marine fish is presumably related to the species distinction in their ecological habits. In comparison with freshwater carnivorous fish, the metabolism energy in these seven species of marine fish is higher than that of the average in the relative freshwater species, indicating that the marine fish should be categorized as those of high metabolic consumption and low growth efficiency.
