在其它条件相同的情况下,三个试验点配合饲科培育鱼种比常规饲料培育鱼种平均增产30.3%至132.3%,每亩每月纯产值高27.97元至84.08元,饲料系数低0.46至1.58。肯定了该配方生产的配合饲料培育草鱼种的效果,配合饲料培育鱼种法适用于鱼种生产中常用的草鱼混养白鲢、草鱼混养花鲢的育种形式。并就改进配合饲料加工工艺和鱼种培育中合理掌握投喂量,以提高配合饲料养鱼效果等提出看法。
Under the same conditions, the average yield of forage breeds in the three experimental points increased by 30.3% to 132.3% compared with the conventional forage breeds. The monthly net output value per mu was 27.97 yuan to 84.08 yuan and the feed coefficient was 0.46 to 1.58. Affirmed the formula produced by compound feed grass carp effect, fodder breeding method is suitable for the production of fish species commonly used grass carp polyculture silver carp, grass carp polyculture flowers silver carp breeding form. And to improve feed processing technology and breeding of fish species to rationally control the amount of feeding in order to improve the effect of fish feed with the proposed views.
