网箱养鱼一开始就遇到附着物问题。其中细菌、真菌以及肉眼看不见的单细胞或微细的藻类,如硅藻等尚未引起人们普遍注意。据报导,海洋附着生物大约200种。淡水方面尚未充分研究。目前,注意力多集中于对网箱养鱼造成显著影响的“大型”动植物。特别是藻类对网箱养鱼的影响最严重。淡水中主要是绿色丝状藻。海水着生藻类种类繁多,有绿色、棕色和红色的。它们都需要光线,所以集中着生于网箱中水体透光层部位,一般群生在网箱上半部2米范围内。最常见的是绿色的浒苔(Enteromorpha)。在混浊水体中,由于阳光受水中悬浮颗粒的阻隔,不宜藻类的繁生,但有污着出现。
Cage fish encounter attachment problems from the very beginning. Among them, bacteria, fungi, and unidentified single cells or fine algae, such as diatoms, have not drawn the attention of people. It is reported that there are about 200 marine attached organisms. Fresh water has not yet been fully studied. At present, attention is more focused on “large” animals and plants that have a significant impact on cage fish production. In particular, algae have the most serious effects on cage fish culture. Fresh water is mainly green filamentous algae. There are a wide range of seaweed algae, green, brown and red. They all need light, so they are concentrated in the translucent layer of water bodies in the cages, usually living within 2 meters of the top half of the cage. The most common is the green Enteromorpha. In the turbid water body, due to the sun by the suspended particles in the water barrier, not algae, but there is pollution.
