摘    要:以大黄鱼为研究对象,进行了饲料和体重对其氨氮排泄率影响的实验.研究结果表明,大黄鱼的排氨率受饲料影响显著,投喂配合饲料的排氨率约为投喂杂鱼饲料的2倍,两者存在显著差异(P〈0.05).投喂配合饲料的平均排氨率分别达到5.82±0.94mg·(h·kg)^-1(116.7g)、4.80±0.48mg·(h·kg)^-1(204.9g)、3.43±0.53mg·(h·kg)^-1(313.5g),而投喂杂鱼饲料的平均排氨率分别只有3.16±0.20mg·(h·kg)^-1(116.7g)、2.41±0.18mg·(h·kg)^-1(204.9g)、1.93±0.11mg·(h·kg)^-1(313.5g);大黄鱼排氨率同样受体重影响,并且随着体重的增加排氨率减少,二者的关系式分别为线性方程:U=-0.006 1W+3.798(R^2=0.8963)(杂鱼饲料)和U=-0.012 1W+7.251(R^2=0.7527)(配合饲料).

Abstract:Take the yellow croaker as the research object,we carried on an experiment to test how food and weight influence the ammonia nitrogen excretion.As a result of the test,the yellow croaker's ammonia excretion rate significantly was affected by the feed,the ammonia excretion rate was approximately 2 times in the group which feed on the mixed fish than that in the group which feed on the miscellaneous feed,and differ greatly in groups of different food(p < 0.05).The average ammonia excretion rate of groups feed...
Keywords:yellow croaker  the ammonia excretion rate  weight  food
