Embodiment

[0020] Mandarin fish ponds use cassia to regulate fertilizer and water: there are 4 ponds in a mandarin fish farm in Xinhui, Jiangmen, Guangdong Province, and cages are placed around and in the middle of the ponds. The cages are 2 to 4 meters wide, 4 to 8 meters long, and 1.5 to 1.5 meters high. 3.0 meters. Seedlings were released in May 2016, and cassia was regularly placed in two of the ponds on July 1. It was used 3 times a month, and the dosage was 2.67 kg / mu·m water depth each time. Use March. Continuously detect water body indicators such as total suspended solids (TSS, Total suspended solid) content, ammonia nitrogen, nitrous acid, and pH. The results showed that the content of TSS increased, the content of ammonia nitrogen decreased, and the content of nitrite nitrogen decreased in the Cassia officinalis group (attached Figure 1~3 ). The diseased fish in the pond were detected, and the diseased fish in the control pond 1 were detected to be positive for infectious ...

Abstract

The invention provides a method of dressing the mandarin fish pond using cassia tora and preventing the mandarin fish from diseases. In the mandarin fish culture period, the cassia tora plant is harvested, after being tied in bundles, the cassia tora plant bundles are put into a pond, and topdressing is conducted on the mandarin fish pond and measures of disease prevention are taken for the mandarin fishes. According to the method, fresh cassia plants are adopted for enriching the pond water, the weaknesses that the ordinary fertilizers are difficult to store and inconvenient to use are overcome; in addition to the rich water function, the method has also the functions of stress reduction and disease resistance for the mandarin fish, the disease resistance of the mandarin fish is increased, the cultivate rate of the mandarin fish and the economic benefits are improved, and the ability to resist disease risks of mandarin fish culturing is facilitated.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for reducing diseases by using the herbal medicine Cassia chinensis to fertilize and water mandarin fish culture ponds. Background technique [0002] Mandarin fish is a characteristic breeding species in my country, with a national annual output value of about 14 billion yuan. The bacterial pathogens of mandarin fish mainly include Cellulophila columnar, Aeromonas hydrophila, etc., and the main viral pathogens include infectious spleen and kidney necrosis virus, rhabdovirus, etc. Once these infectious diseases occur, treatment is difficult and the harm is extremely serious. Mandarin fish takes bait fish (mainly dace in the south) as food all the year round, and cannot directly swallow bait, and can only obtain it indirectly through bait fish, and it is difficult to obtain medicine by oral method. The current methods of preventing mandarin fish diseases mainly ado...
