进行水产科学研究，常常需要应用小型网箱。由于实验的类型、规模、进程不同，需要使用的网箱规格差异很大，往往无法在市面上直接采购到合适的定型产品，大多需要实验研究人员自行制作。许多人自行制作网箱时釆用铁制框架，使用中很快就会锈蚀，且脱落的铁锈对水质将造成不利影响；若用铝合金材料或不锈钢管做框架，则制作成本较高，而且暂时不用的网箱又占据大量场地，堆放过程又会加剧铁质网箱框架的氧化锈蚀。为解决上述问题，作者根据多年 Scientific research in aquaculture often requires the use of small cages. Due to the different types, sizes and processes of experiments, the specifications of the cage to be used vary greatly and often can not be procured directly from the market to the appropriate stereotyped products, most of which need to be produced by experimental researchers. Many people make cages by themselves when using iron frame, the use of rust soon, and the fall of the rust on the water quality will be adversely affected; if the aluminum alloy or stainless steel pipe frame, the production cost is higher, and Temporarily unused cage occupy a large number of sites, stacking process will exacerbate the iron cage cage oxidation corrosion. To solve the above problem, the author based on many years
