生产上的鱼种培育通常是指将寸片小规格鱼种经过4～5个月的精心饲养使之达到全长12～20cm、尾重40～100g这样大规格鱼种的全过程。长吻(鱼危)鱼种培育的关键技术,一是转食驯化,二是配合饲料。 1.转食驯化 根据我们的经验,转食驯化宜在几十平方米的小水泥池里进行,转食之后的饲养则在几百到一千平方米的泥底鱼池里进行为好。 每平方米标准池可放养长吻(鱼危)寸片100～200尾,让其在池内适应1～2天后就可投喂转食用的人工配合
Production of species cultivation is usually refers to the small size of the small pieces of species after 4 to 5 months of careful feeding to reach the full length of 12 ~ 20cm, tail weight 40 ~ 100g such a large size of the entire species of fish. Long kiss (fish danger) fish breeding key technologies, one is fed food domestication, the second is with feed. 1. Feeding and domestication According to our experience, feeding and domestication should be carried out in a few dozen square meters of small cement ponds, feeding after rearing in the hundreds of to a thousand square meters of mud fish ponds as well. Standard square per square meter can be stocking long kiss (fish risk) inch pieces of 100 to 200 tail, let it adapt to the pool 1 to 2 days after the feeding of artificial feeding
