California perch farmers reported that the phenomenon of anchorhead loach in the pond caused the wound to be infected by bacteria and viruses, and the temperature began to gradually decrease and it was easy to break out of water mold. Anchorhead bream bites the surface of the California perch inflamed and swollen, erythema appears, necrosis. If it cannot be treated in time, it will also cause punctate infection, iridescent virus, nocardiosis, etc., resulting in an increase in mortality.
Why is it easy to erupt anchorhead bream in late autumn and early winter?
First of all, the water temperature in late autumn and early winter is suitable for the growth and reproduction of anchorhead loach, and secondly, the plankton in the water body is reduced, and the natural enemies against anchorhead loach are also reduced, and the water temperature decreases very easily to pan the bottom, resulting in the bottom anchor loach floating, increasing the probability of anchor loach infection. Finally, the winter light time is short, the intensity is weak, and the photosynthesis of algae is weakened, which is very easy to cause hypoxia floating head and other conditions to cause poor physical fitness of California perch, which is easy to be parasitic by anchorhead bream.
Anchorhead bream prevention and control recommendations
First, timely water change, increase the amount of water exchange, increase the type of plankton, prevent the breeding of cyanobacteria and green algae, pay attention to fertilization before the water temperature decreases, you can choose biological fermentation organic fertilizer, a small number of times to use, increase the water body fertilizer.
Second, regular use of bacillus sprouts, photosynthetic bacteria stable more, lactic acid bacteria lactic acid and other microbial preparations, the cultivation of beneficial bacteria algae, reduce ammonia nitrogen, salt, hydrogen sulfide and other toxic and harmful substances to reduce the harm to water and substrate.
Third, after the cooling, the California perch is weak, can no longer use insecticides to kill the anchorhead loach in the water, you can use pure Chinese medicine products Che Jing / Baicao to drive the net regular feeding and sprinkling, in order to kill the anchorhead loach parasitic in the water body, parasitized in the fish body.
Fourth, scientific feeding, reasonable control of materials. Especially after the temperature drops, excessive feeding will not only cause feed waste, but also deposit the bottom of the water, aggravating the problems of excessive ammonia nitrogen salt and low dissolved oxygen in the water body, which further causes the deterioration of water quality.
Fifth, regular mixing of ingredients to take the hero liver and gallbladder, to help California perch body fat conversion, reduce the burden of liver and gallbladder, improve the physical health of California perch, enhance the anti-stress ability of California perch, California perch physical health, anchorhead perch naturally has no way to parasitize.
