| 摘要: |
| 对厦门海区的多鳞鱚(Sillago sihama)和锯塘鳢(Prionobutis koilomatodon)的生化组成及比能值进行了研究。结果表明, 除锯塘鳢粗脂肪含量与水分含量为显著相关外(P<0.05), 两种鱼的粗蛋白含量、粗脂肪含量、粗灰分含量和比能值均与水分含量之间存在极显著负相关关系(P<0.01); 除锯塘鳢粗脂肪与比能值为显著相关外(P<0.05), 两种鱼的水分含量、粗蛋白质含量、粗脂肪含量、粗灰分含量和干物质含量与比能值之间均存在极显著的相关关系(P<0.01)。因此, 在对误差要求不严格的条件下, 水分含量可以用来间接估算多鳞鱚和锯塘鳢鱼体的生化组成和比能值, 进而用于野外鱼类能量学和生态系统能流分析的研究。 |

| Abstract: |
| The whole biochemical composition and calorific value of Sillago sihama and Prionobutis koilomatodon caught in Xiamen sea area were measured. The results show that: except crude lipid content of P. koilomatodon(P<0.05), the contents of crude protein, crude lipid, crude ash and calorific value of S. sihama and P. koilomatodon have significantly negative relationships with water(P<0.01); except crude lipid content of P. koilomatodon(P<0.05), the contents of water, crude protein, crude lipid and crude ash of S. sihama and P. koilomatodon have significantly relationships with calorific value (P<0.01). Therefore, under the condition of no strict demand for the error, water content can be used to estimate the biochemical composition and calorific value of the two species, research fish bioenergetics, and make energy flow analysis of ecosystem. |
