传统草鱼养殖,投放的是2～3龄大规格鱼种,以投喂草食性饲料为主。这种养殖方式养殖周期长,发病和泛池的死亡率高。我们经过几年的实践探索,运用筛选优质鱼种、投喂全价颗粒饲料、合理放养和加强水质管理等综合技术措施,将当年夏花草鱼种养成商品鱼,可大大节省养殖成本。
Traditional grass carp breeding, put 2 to 3 age-class large-scale species of fish to feed herbivorous feed-based. This breeding method of breeding cycle is long, the incidence and pan-pond high mortality. After several years of practical exploration, we have adopted comprehensive technical measures such as screening high-quality fish species, feeding full-price pellet feed, rationing and strengthening water quality management, and cultivating summer summer grass species into commercial fish, which can greatly save breeding costs.
