Grass carp, Astragalus membranaceus, refers to the mass death of grass carp caused by mixed infections of grass carp gill disease and red bark disease before and after barley yellow. The obvious symptoms of the disease are: rot of the diseased fish reel with sludge, fibrillation of the silk crevices to form tinea versicolor; diseased fish scales fall off, redness of the body surface, and the fins are infested with worms. The base of the fins rot.
Grass carp, Astragalus membranaceus, is a highly contagious disease. If it is not treated in time, grass carp can be completely destroyed, eventually leading to the failure of grass carp breeding.
Although the grass carp is relatively contagious, as long as it is scientifically prepared for prevention, it can control the disease:
(1) Do a good job of disinfecting the body of water. Disinfect the body of the body with dibromohydantoin, bromochloroheine or fish for 5 to 7 days.
(2) Scientific feeding of internal medicines. If grass carps are found to have signs of disease, drugs with better therapeutic effects (such as erythromycin for aquatic use) should be fed for 5-7 days.
(3) Control the feeding amount. Grass carp has a gluttonous habit, and the daily feeding amount should be controlled below 3% of the fish's weight.
(4) Forage combination. Since grass contains unknown growth factors that promote the healthy growth of grass carp, when feeding full-priced compound feed, a certain amount of grass can be properly matched to promote the growth of grass carp.
