小网箱养鱼是史密脱教授多年研究成功的一项高密度、集约化养鱼新技术。这项技术1991年传入我国,经过几年的推广,证明小网箱养鱼具有投资省(每立方米1000元左右),见效快(投放鱼种后4—5个月即可长成商品鱼),产量高、效益好(每平方米可产鱼150～200公斤、获利300—500元),易管理、应用广、机动灵活、操作方便等特点,不仅适合大规模养殖,也适合一家一户的小规模养值。是一项推广价值较高的新技术。为了进一步推广这项新技术,现将小网箱养殖技术介绍给广大读者。
Small cage fish farming is Professor Smith’s many years of successful research on a high-density, intensive fish farming new technology. This technology was introduced to our country in 1991, and after several years of promotion, it proved that the small cages have an investment province (about 1,000 yuan per cubic meter) for fish farming, which can be effective (4-5 months after the fish is put into use) Fish), high yield, good efficiency (fish per square meter can produce 150 ~ 200 kg, profit 300-500 yuan), easy management, wide application, flexible, easy to operate and other characteristics, not only for large-scale breeding, but also suitable A family of small-scale maintenance value. Is a promotion of high value of new technologies. In order to further promote this new technology, introduce the technology of small cage farming to the readers now.
