To examine the effects of dietary starch on the growth performance and digestive encyze actirities of Hephaestus fuliginosus,diets containing iso-nitrogenous,iso-lipidic but increasing starch levels(26%,30%,34%,38% and 42%) were used to feed experimental fish for 60 days.At the end of the experiment,the Hephaestus fuliginosus fed 34% starch level showed higher relative weight and protein efficiency ratio,lower feed conversion ratio than other groups(P<0.05),higher level of crude lipid compositions of whole ...
