Description

Technical Field

[0002] Algae are a type of eukaryotic organisms in the protist kingdom. They are mainly aquatic, have no vascular bundles, and can photosynthesize. They vary in size, ranging from single-celled flagellates as small as 1 micron in length to large brown algae as long as 60 meters. Algae fix inorganic carbon through photosynthesis and convert it into carbohydrates, thus providing the basis for the productivity of the water area. The total productivity of marine phytoplankton is estimated to be 31×109 tons of carbon per year. In the conversion of the food chain, 1 kg of fish meat requires about 100 to 1,000 kg of phytoplankton. Therefore, sea areas rich in phytoplankton resources are all home to world-famous fishing grounds, and the output of phytoplankton has become an indicator for estimating marine productivity. In pond fish farming, water quality is generally judged by water color, which is determined by the dominant species of algae and their degree of reproduction.
