Growth rate, apparent digestibility of protein and protease activity in intestine and hepatopancreas were determined in two months. The results showed that Chinese herb additives significantly increased growth rate, protease activity in intestine and hepatopancreas, and apparent protein digestibility of allogynogenetic crucian carp( P 0. 01) . The growth rates of the treated groups 1% of additive Ñ, 2% additive Ñand 2% additive Ò were 2 . 74% , 2. 74% and 47. 06% higher than those of the control respectively. The effect of the additives on protease activity in intestine and hepatopancreas, and apparent digestibility of protein was the same as the growth rate. Protease activities of the control and the treated groups 1% of additive Ñ, 2% additive Ñ, 2% addit
