摘　　要：为探索鱼类资源保护和养殖技术,研究了不同光照强度环境中大眼鳜幼鱼摄食特性及摄食强度.结果表明,大眼鳜幼鱼与翘嘴鳜有相近摄食习性——喜黑暗环境摄食,在黑暗环境中摄食强度最大,其摄食量分别是自然光及强光环境的1.1,2.0倍.To obtain fish resources’ protection and its feeding technology,ingestion characteristics and the ingestd amount were observed.It could be concluded that Siniperca kneri Garman was similar ingesting customs to the Siniperca chuatsi (Basilewsky).They both like ingesting in faint light.The ingested amount was the higest in dark,which was 1.1 times of that in natural light,and 2.0 times of that in bright.
