The chlorophyll content of the sea area is affected by many factors. Generally speaking, the factors affecting the chlorophyll content of the ocean are temperature, luminosity and nutrient concentration. These factors will change with the change of the day. The chlorophyll analyzer therefore has the marine chlorophyll content. The so-called daily growth and decline phenomenon. However, the chlorophyll content in the marine area affects the production of fish and shrimp. The chlorophyll measurement is used to understand the approximate yield of the fish and shrimp. The chlorophyll measurement in the sea area can only use the most common measurement method, but if it is on land, the individual It is recommended to use the chlorophyll detector, chlorophyll meter, SPAD502 chlorophyll meter for measurement.
In marine ecosystems, the yield of fish, shrimp, shellfish, etc. is closely related to the level of chlorophyll content. In the sea area with high chlorophyll content, the yield of fish, shrimp and shellfish will be high. However, in some estuary and offshore waters, due to the rich nutrient salts caused by river pollution, the excessive growth of algae, that is, the so-called eutrophication of water quality. Excessive algal growth leads to an increase in chlorophyll content. It is not good to raise fish in these places. Those pollution will enter the body of the fish and eventually enter the human body, endangering people's health.
Fish farming can promote the eutrophication of water bodies. On the one hand, fish activities and feeding promote the circulation rate of nutrients in water bodies. On the other hand, the feeding of baits in fish cages increases the biomass of phytoplankton, both of which can promote Photosynthesis of phytoplankton. Other studies have shown that the chlorophyll content of fish farms is significantly higher than that of fish-free areas. Insufficient feeding of fish in fish culture areas may cause fish to feed on micro-phytoplankton and micro-phytoplankton, resulting in low chlorophyll content in fish culture areas. The species, density, and chlorophyll content of fish cultured in the main fish culture area also have an impact on the chlorophyll content. For example, the density of fish culture in the fish culture area is too large, and the fish feed on the micro phytoplankton and micro phytoplankton in the primary productivity, which makes The chlorophyll content in the fish culture area is lower than that in other sea areas.
