| Summary: | In recent years,many countries have tried to decrease the nitrogen (N) excretion from animal production for its potential damage to the environment. Fish farming is an important N letting-off sector and should reduce its nitrogen (N) loads while maintaining optimal production. In fish farming production, N waste consists of excretory products and N-containing in faecal products. Research has been done focusing on the water output quality and total ammonia nitrogen (TAN) (Cheng et al. 2003). Several models have been developed to study the N output from fish farming (Frier et al., 1995; Doglioli et al., 2004). |
