养鱼传统上对水色的“肥、嫩、爽、活”之说,其实质是水中浮游生物种类组成和变化及水体理化 因子的综合反映。养鱼池中的水色主要是由池中繁殖的浮游生物所造成。因此,根据水色可以推知池中浮游生物的大致组成,并推断出水质的肥瘦与好环,从而采取相应的措施调节水质,以利池鱼的生长。养鱼池中的水色大致分为以下几种:1 褐色水(包括黄褐、红褐、褐带绿)呈上述颜色的池水浮游值物的优势种类多为硅藻。有时隐藻大量繁殖时也呈褐色。褐带绿的水中含有较多的微细浮游植物,如绿球藻、栅藻等。这类水中的浮游值物作为鱼的食料,易于消化吸收,因此这种水
Aquaculture traditionally refers to the “color, tenderness, coolness and liveliness” of watercolors, and its essence is the comprehensive reflection of species composition and changes of plankton in water and physical and chemical factors of water bodies. The color of aquarium fish is mainly caused by the plankton breeding pond. Therefore, based on the color of water, the general composition of plankton in the pond can be inferred and the fat and good quality of the water quality can be inferred. Therefore, corresponding measures can be taken to regulate the water quality to facilitate the growth of the pond fish. Aquarium fish in the water can be broadly divided into the following categories: 1 brown water (including brown, reddish brown, brown band green) The color of the pool of water are the dominant species of diatom. Occasionally, cryptococcosis is also brown when it multiplies. Brown-green water contains more fine phytoplankton, such as Chlorococcum, such as algae. This kind of water in the floating material as fish food, easy to digest and absorb, so this kind of water
