随着人民生活质量的提高,国际、国内市场对鲍的需求量巨大,市场前景广阔。因此,鲍的人工养殖在我国得以迅猛发展,海上筏养鲍鱼方式备受养殖者的喜爱。随着养殖规模的扩大,养殖效益有逐年下滑的趋势,使不少养鲍单位转产他业,究其原因,错综复杂,既有自然因素,也有人为因素。笔者结合生产实践,认为应从6方面入手,提高筏养鲍鱼效益:(一)精心挑选大规格的优质杂交鲍鱼苗北方养殖的鲍鱼主要品种为皱纹盘鲍,皱纹盘鲍经过多年的养殖,海区相近,近亲繁殖,种质严重退化,当地鲍鱼的遗传质量下降,对变化了的自然环境缺乏应有的适应性。通过杂交培 With the improvement of people’s living standards, there is a huge demand for abalone in the international and domestic markets and the market has a bright future. Therefore, abalone’s breeding farms in our country can be developed rapidly, abalone raised by sea breeders much loved by farmers. With the expansion of breeding scale, the benefit of breeding has been declining year by year, leaving quite a few units for rehousing him to engage in other trades. The reasons for this are complex, both natural and man-made. The author combines the production practice, that should be from six aspects to improve raft raise abalone benefits: (A) selection of large-size high-quality hybrid abalone The main species of abalone farmed in North China is abalone abalone, Abalone abalone after years of farming, the sea is similar , Inbreeding, serious deterioration of germplasm, the decline of the genetic quality of local abalone, lack of adaptability to the changed natural environment. Through hybrid training
