【文章內(nèi)容簡介】 。100g1 at 19℃, 23℃and 27℃respectively。（2） the daily ration and water temperature showed a linear relationship, the regression equation was y= （R2 = ）.4. The feeding ration of loach under different research included 4 experiments as followed, observe the feeding condition, feeding speed, feed dissolving rate under microwater aquaculture with no loach and the correction coefficients of feed dissolving rate under microwater aquaculture below regular feed of results showed that,（1） the satiation time of loach was about in largescale loach farming industry。（2） the feeding rations of loach were 100g1,100g1 and 100g1 at 19℃, 23℃and 27℃. The effects of feeding frequency on growth, food conversion efficiency and body position of health loach fishes randomly divided into 3 groups, each with 210 fishes and with respectively 3 repeats of 70 fishes in net scale of feeding was 4 percent of body weight of loach per day. A growth trial of loachwas conducted on the effects of four different feeding frequencies （2, 3 and 4 times per day）. The result showed that, in the experiment the suitable feeding frequency of loach was 4 times per . The effects of feeding level on growth, food conversion efficiency and body position of health loach fishes randomly divided into 3 groups, each with 60 fishes and with respectively 3 repeats of 20 fishes in fishbowls. A growth trial of loach was carried out at ration levels （3%, 4% and 5%）.The result showed that, in the experiment the suitable feeding level of
