细鳞鱼在人工流水养殖下的生长特性
Growth Characters of Lenok Brachymystax lenok Cultured in a Flowing Water Pond
【摘要】 利用2.8~16.8℃泉水,进行细鳞鱼工厂化流水养殖,12、24、30月龄的体重分别可以达到60.53±27.60g、323.37±74.61g和735.83±164.80g。要达到500g上市规格,需要24~28个月。1龄鱼生长比较缓慢,2、3龄生长速度较快。体重变异系数变化较大,在20~55%之间。
【Abstract】 Juvenile lenok Brachymystax lenok were reared in ponds with running water at 2.8-16.8℃.,and had mean body weight of 60.53±27.60g in 12 months,323.37±74.61g in 24 months,and 735.83±164.80 g in 30 months.The lenok will have marketable body weigh of over 500 g in 24~28 months.The lenok showed better growth in 2~3 years old than in 1 year old.The coefficient variation in body weight wase changed from 20% to 55%.
