Maintenance ration and conversion efficiency of Hyporhamphus sajori

Abstract

Abstract: The maintenance ration and conversion efficiency of Japanese halfbeak,Hyporhamphus sajori were tested with enclosures installed in a shrimp raising pond.The results showed that there existed an evident relationship between daily ration(DR)and growth rate(GR) of the fish,GR=140.37DR-24.03.The conversion efficiency was 13.96% in biomass or 16.12% in energy.The maintenance ration was 17.12% and 20.39% of body weight in terms of growth rate and specific growth rate,respectively,indicating that it could be deduced from growth rate quite differently from that from specific growth rate in the same experiment.The abnormal growth rate appeared when daily ration was below 3.30% of body weight,implied that Japanese halfbeak may get other food resources besides supplied net zooplankton.
