今年,对虾养殖情况不理想,病害多,养殖成功率低。于是,关于对虾亲本退化、水环境恶化、养虾难、以及原料成本上涨导致饲料配方大幅缩水的种种,众说纷纭。前段时间的一个学术研讨会上,华南某知名饲料企业资深技术人员甚至把今年对虾长速慢、病害多的原因归咎于虾苗。此观点一爆出,行业众说纷纭。有的认为太主观,有的则为苗场叫屈。事实上,对虾养殖高速发展的这10来年,也是虾苗行业的快速发展期。这期间,华南的省级对虾良种场如今有不下18家,有近一半集中在湛江。
This year, the shrimp farming situation is not ideal, disease and breeding success rate is low. As a result, there are divergent opinions on the degradation of shrimp parents, worsening of the water environment, difficulties in raising shrimp, and the drastic shrinkage of feed formulations resulting from rising raw material costs. An academic seminar a while ago, a well-known feed enterprises in southern China and even senior technicians shrimp this year’s long slow, many diseases attributed to shrimp. A burst of this view, the industry divergent opinions. Some think it is too subjective, while others give the seedling the nickname. In fact, the rapid development of shrimp farming these 10 years, but also the rapid development of the shrimp industry. During this period, there are now no fewer than 18 provincial shrimp breeding farms in southern China, with nearly half concentrated in Zhanjiang.
