摘要

摘要用4个月大的幼鱼进行了90天的试验，测试了大豆浓缩蛋白（SPC）替代鱼粉（FM）水平不同的7种日粮：0%（对照日粮）、45%、55%、65%、75%、85%或100%，分别对应于0、312、383、451.6、521.7、590或695g SPC kg−1日粮。从55%及以上的替代水平开始补充蛋氨酸和精氨酸，以达到与对照饮食相似的值。存活率接近100%。对照饮食达到了最高的总长度（TL）和重量（W），在45%至55%的饮食中没有显著差异。在65%或更高的置换水平下，TL、比生长率和总长度的日增量显著降低。外观可见畸形的鱼类比例在0%至9.3%之间，75%、85%和100%的替代日粮更高。

Growth and feed utilization of juvenile tench (Tinca tinca L.) given diets in which soy protein concentrate replaces fishmeal and methionine and arginine are used as amino acid supplements

ABSTRACT A 90-day experiment was conducted with four-month-old juvenile tench to test seven diets differing in replacement level of fishmeal (FM) by soy protein concentrate (SPC): 0% (control diet), 45%, 55%, 65%, 75%, 85% or 100% corresponding to 0, 312, 383, 451.6, 521.7, 590 or 695 g SPC kg−1 diet, respectively. Methionine and arginine supplementation was included from substitution levels of 55% and above to reach similar values to those provided by the control diet. Survival rate was close to 100%. The highest total length (TL) and weight (W) were reached with the control diet without significant differences from 45% to 55% diets. Significant lower TL, specific growth rate and daily increment in total length were obtained with 65% or higher replacement levels. The percentages of fish with externally visible deformities ranged from 0% to 9.3%, being higher with 75%, 85% and 100% replacement diets.
