Problems solved by technology

For the prevention and treatment of streptococcal disease in tilapia, there is no legal vaccine commercially available on the market at present, mainly through drug (antibiotic) method of prevention and treatment. However, once there are stress situations such as drug withdrawal, increased feeding, deterioration of water quality, rise in water temperature, or start of fishing, the death of tilapia will continue or even the number will increase. The control effect is not ideal, resulting in low yield of tilapia

Abstract

The invention provides a Tilapia mossambica cultivation method and belongs to the technical field aquaculture. The cultivation method includes: processing a cultivation pond, processing cultivation water, culturing algae and regulating water, putting Tilapia mossambica fry into the cultivation pond, feeding the Tilapia mossambica fry with preprocessed feed and the mixed powder of rhubarb, radix scutellariae and cortex phellodendri, regulating water in the early stage of cultivation, regulating water in the middle and late period of cultivation, and harvesting the Tilapia mossambica. The methodhas the advantages that the incidence rate of Tilapia mossambica streptococcicosis can be lowered effectively, the survival rate of the Tilapia mossambica can be increased, Tilapia mossambica growthcan be promoted, and Tilapia mossambica yield can be increased; the method does not antibiotics and is ecological and environmentally friendly; compared with the prior art, the method can lower the incidence rate of Tilapia mossambica streptococcicosis by more than 73.99%, increase the survival rate of the Tilapia mossambica by more than 31.22%, increase the average final weight of the Tilapia mossambica by more than 15.91% and increase the mu yield of the Tilapia mossambica by more than 52.23%.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating tilapia. Background technique [0002] Tilapia is a high-quality fish species recommended by the Food and Agriculture Organization of the United Nations to the world. It has fast growth, high yield, easy reproduction, miscellaneous food habits, wide adaptability, tender and delicious meat, and no intermuscular spines. It is popular among producers. and consumers' welcome. However, in recent years, with the rapid development of the tilapia industry, the increase in breeding density and the deterioration of the breeding environment, the outbreaks of streptococcal disease in tilapia have become more and more frequent. Disease transmission and infection. [0003] There are three main methods of disease control in aquaculture animals: drug control, ecological control, and immune control. For the prevention and treatment of streptococcal disease in tilap...
