Description

technical field [0001] The invention belongs to the technical field of fish farming, in particular to a method for preventing and treating saprolegniasis of perch. Background technique [0002] Perch, also known as flower perch, Zhaihua, perch board, and four-rib carp, is mainly distributed in the western Pacific Ocean and the coast of China. Among them, there are many in the Yellow Sea and Bohai Sea. It is a common economic fish and one of the species for developing mariculture. Sea bass is rich in nutritional value, rich in protein, vitamin A, vitamin B, calcium, magnesium, zinc, selenium and other nutrients. It has the effects of nourishing liver and kidney, benefiting spleen and stomach, reducing phlegm and relieving cough. Because the sea bass meat is rich in nutrients and water, the muscle tissue is fragile, the endogenous protease is active, and the autolysis speed is fast, so it is easy to spoil and deteriorate. [0003] Saprolegnia, all belong to algae fungus, the ...
