一、压缩常规苗种数量,大力发展名优品种育苗 目前,全国已掀起了以鱼类养殖为主的第4次海水养殖高潮,以生物育种技术为基础的第5次海水养殖浪潮正在酝酿和发展中。专家预测,全国对海水养殖鱼类苗种,特别是高科技苗种的需求将增加,市场前景广阔。因此,凡是基础设施完善、条件比较优越、技术力量比较雄厚的育苗单位,完全可以压缩常规苗种数量,开展鱼类等高科技苗种的生产,如牙鲆、大菱鲆、真鲷、黑鲷、黑鱼君、六线鱼、美国红鱼等,这样既可减少常规大众化苗种数量,分散竞争压力,又能优化品种结构,提高经济效益。同时,鱼类育苗可以与虾、蟹、贝类等常规品种育苗轮茬进行,提高育
First, to reduce the number of conventional seedlings, vigorously develop the breeding of famous varieties At present, the country has set off the first fish farming climax of the fourth aquaculture, biological breeding technology based on the 5th wave of mariculture is brewing and development in. Experts predict that there will be an increase in demand for mariculture fish species, especially high-tech seed varieties, and the market will have a bright future. Therefore, all the nursery units with perfect infrastructure, superior conditions and strong technical force can completely reduce the quantity of conventional seed and carry out the production of high-tech seed such as fish, turbot, sea bream, black sea bream, Sea bream, blackfin monkeys, hexagrams, American redfish, etc. This will not only reduce the number of conventional popularization seeds, diversify the competitive pressures, but also optimize the variety structure and increase economic benefits. At the same time, fish breeding can shrimp, crab, shellfish and other conventional varieties nursery rounds to raise and raise
