Abstract
The rice filed eel was fed for 8 weeks by rice field eel'formula diet that replaced fish meal' separately with soybean meal by 0.0%,7.5%,15.0%,22.5%,30.0%,37.5%.The results showed that with the increase of amount of soybean meal,the productivity of the rice field eel reduced gradually.But within 15% soybean meal,the rice field eelss productivity had no significant discrepancy.The content of the fish meal should not be low to 30% in rice field eelss diet.
