Abstract
To study the effects of fish body size on breath and metabolic status of Thamnaconus septentrionalis,the oxygen consumption rate,ammonia excretion rate and asphyxia point of T.septentrionalis with different sizes[(21.51±4.78),(44.55±3.18),(76.98±7.33)and(153.79±4.99)g]were determined by still water closed breathing chamber method.The results showed that the oxygen consumption rate and ammonia excretion rate of T.septentrionalis significantly decreased with fish size increasing(P<0.05).The asphyxia points of T.septentrionalis increased with the increase of fish body size,and the lowest level was observed in(21.51±4.78)g group(P<0.05),while there was no significant difference among other groups(P>0.05).The oxygen-nitrogen ratio was 6.27～18.53,indicating that the main energy supply substance of T.septentrionalis under the test conditions was protein.The results showed that the fish body size had a significant effect on the oxygen consumption rate and ammonia excretion rate of T.septentrionalis,but had no significant effect on the asphyxia point.关键词
