Biochemical composition and calorific value of Sillago sihama and Prionobutis koilomatodon
多鳞鱚和锯塘鳢的生化组成及比能值研究

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.
