海洋养殖中使用的定置渔网,在接触有机物、细菌后,硅藻类就会繁殖,而以硅藻为食的贝类、藤壶等海洋生物就会集聚附着,不仅会造成流伴阻力增加引起渔网的污损,而且会造成贫氧感染症引起鱼的发育不良等问题。
The fixed fishing nets used in marine aquaculture will breed diatoms when exposed to organic matter and bacteria. Marine organisms such as shellfish and barnacles feeding on diatoms will accumulate and attach, which will not only increase the flow resistance and cause the fishing nets Of the defaced, but also cause problems such as poor growth of fish caused by oxygen-depleted infections.
