针对福建省网箱养殖的现状及存在的问题,通过改进网箱的设置和布局,在网箱间设置流水通道,以改善养殖系统的小生态环境;把3m×3m×4m或4m×4m×4m的网箱,改为6m×6m×5m的大规格网箱;制作软颗粒饲料投饵花鲈;改进日常管理操作如换网、洗网、点数的工具和方法;建立病虫害综合防治制度等技术:总结出了一套切实可行的花鲈网箱养殖的高产技术。2年的养殖实验结果表明,每个6m×6m×5m的网箱每年可养殖花鲈1225-1545kg,日平均死亡率小于1‰。
Aiming at the status quo and existing problems of cage culture in Fujian Province, the water channel was set up between cages by improving the arrangement and layout of cages, so as to improve the small ecological environment of breeding system. The 3m × 3m × 4m or 4m × 4m × 4m cages, to 6m × 6m × 5m large size cages; production of soft pellets feeding perch; improve daily management operations such as changing network, washing nets, points of tools and methods; establish a comprehensive pest control system Technology: Summarized a set of high-yielding technology for the cultivation of cages per cage. The results of two years of aquaculture experiments showed that each 6m × 6m × 5m cages can breed 1225-1545kg per year and the average daily mortality rate is less than 1 ‰.
