Based on f low..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 f ish can be classed into three categories: ( 1) lower metabolic consumption and higher growth eff iciency, e. g . Schlegel.. s black rockfish and finespot goby; ( 2) higher metabolic consumpt ion and lower growth ef ficiency, e. g. black porgy and fat greenling; ( 3) both metabolic consumption and growth ef ficiency 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 f reshwater carnivorous f ish, the metabo lism energy in these seven species of marine f ish is higher than that of the average in the relative f reshwater species, indicating that the marine fish should be categorized as those of high metabolic consumption and low growth eff iciency.
