For tilapia, streptococcal disease is a hurdle that cannot be overcome, and it can be described as the number one enemy of the tilapia farming industry. In recent years, the high temperature in summer is easy to break out the disease and cause a large number of deaths. The main epidemic time of Streptococcus tilapia is during the high temperature period from May to October, and the peak period of the disease is from July to September. The mortality rate of infected fish can reach 60%-100%. Under normal circumstances, if the diseased fish cannot be controlled in time, the peak of its death will last for 2-3 weeks, which will bring huge harm to the aquaculture industry. The disease mainly threatens tilapias weighing more than 100 grams, but in recent years it has been found that fry below 100 grams is also common.
After streptococcus enters the fish body, it directly invades the fish body cells, produces certain toxins, and then destroys the cells, affects normal metabolism, and eventually leads to death. Generally, fish infected with streptococcus swims alone by the pond, body bends and turns, unresponsive, black body color, red and swollen anus, etc., protruding or cloudy and white eyeballs, accompanied by eye bleeding; gallbladder and liver enlargement, Inflammation of the intestines. Streptococcus is a Gram-positive bacterium, which usually exists in the bottom mud and spreads with water, especially in the eutrophic conditions of the water body, it can survive for a long time. Once it enters the high temperature period, it will explode in an all-round way as the water environment changes. Weak fish will be infected first, and then spread to sub-healthy fish in the pond, eventually resulting in a large number of dead fish in a short period of time. Streptococcus is equivalent to the terminal illness of tilapia. Once infected, there is no good way to treat it, and in the process, it will continue to infect some healthy fish.

1. Do a good job in the treatment of pond sediment and pool water. Thoroughly remove the mud at the bottom of the pond before placing the seedlings, and dry the pond to expose it to the sun.
2. Maintain good water quality. Cultivate and maintain good algae during the breeding period, deal with the aging or death of algae in time, and regularly test the pH, ammonia nitrogen and sub-salt of the water body and other indicators.
3. Scientific feeding. Feed high-quality feed, add bile acid and Eucommia leaf extract to the feed. Bile acids can promote the digestion and absorption of fat and the detoxification and detoxification of the liver to ensure the health of the liver; Eucommia leaf extract can inhibit the reproduction of bacteria and viruses, promote the reproduction of beneficial intestinal bacteria, maintain the balance of intestinal flora, and thus protect the intestinal tract . The combination of the two can increase the immunity and disease resistance of fish.
4. Add Lechang eucalyptus essential oil to the mixture. Lechang eucalyptus essential oil is extracted from the leaves of eucalyptus eucalyptus, which grows uniquely in Australia. It is rich in a variety of plant active ingredients and has strong penetrability and permeability. It can penetrate into bacterial cells, destroy the bacterial cell membrane structure, and make the cell membrane Nutrients flow out to achieve the effect of killing bacteria. Natural plant extraction, safe and non-toxic, long-term addition can effectively reduce the incidence of streptococcus. Streptococcus is difficult to treat, and it is currently a high-incidence period. It is necessary to do a good job in prevention and control!
