Abstract
Attempts were made to find out nitrogen and phosphorus loads to aquatic environment resulting from feeding Nile tilapia (Oreochromis niloticus). Two different size groups, small and large, were used. The average sizes of small and large tilapia were 65.2 g and 389.2 g respectively, and three kinds of commercial diets were used for each size. The 3 kinds of commercial diets for tilapia contained in average 33.8% crude protein (
육상에서 틸라피아를 양식할 때 문제가 되는 질소 및 인의 부하량을 측정하기 위하여, 시판되는 상품 사료로 치어와 미성어를 사육하여 사료 중 영양 성분의 소화율과 분의 배설량 등을 통해 환경수계에 미치는 오염 부하량을 추정하였다. 시판되는 틸라피아 사료의 단백질 함량은 평균
