自1994年开始,茌平县水产局即探索出用双层网箱催产建鲤新法。经10年不断完善,形成“摇篮式”催产新模式,在生产实践中获很大成功,其受精率、集卵率、孵化率较之常规池塘催产方式分别提高20％、50％、20％以上,深受广大群众欢迎。1“摇篮”的制作1.1 材料 成鱼网1具、鱼苗网1具(均完好无破损),粗、细竹杆各1批,细扎绳,池塘水位1.5 m。1.2 制作视池塘大小、网具的长宽,适当制作网箱的大小,我们一般制作宽3 m,长30m的大网箱。 第1步:用成鱼网在靠近塘边10m内,架一网箱 Since 1994, Chiping County Fisheries Bureau has explored the new law of using built-up cages for double-layer cages. After 10 years of continuous improvement, a new model of “cradle-type” oxytocin production has achieved great success in production practice. The fertilization rate, egg-collection rate and hatching rate have been increased by 20%, 50% and 20% Above, welcomed by the masses. 1 “Cradle” production 1.1 Materials into a net 1, fry net 1 (all intact), coarse, thin bamboo each batch of 1, thin tie rope, pond water level 1.5 m. 1.2 Depending on the size of the pond, the length and breadth of the mesh, the size of the cage, we generally make a large cage of 3m wide and 30m long. Step 1: Use nets to place a net cage near the pond 10m
