Embodiment Construction

[0010] Choose a place close to the water source and build a greenhouse. The greenhouse is equipped with a ventilation system and multiple breeding ponds; the breeding pond is equipped with an intake and drainage system, and floating aquatic plants are planted. The breeding greenhouse is built with plastic film, 30 meters long and 10 meters wide meters, 3 meters high; the breeding pond is 6 meters long, 4 meters wide and 1.5 meters deep. The constructed greenhouses are fully disinfected, and healthy fry are purchased and stocked in the breeding ponds in early June.

[0011] The juveniles that have just been put into the breeding pond should not be fed with food immediately. Wait until 3 days to start feeding, and feed the larvae in the juvenile stage. The daily management should be done to change the water every 10 times, and 1 / 4 of the water is changed each time.

[0012] When the fish grows to 100 grams, the food to be fed will be small fish, chicken and duck viscera and left...

Abstract

The invention discloses a culturing method of snakeheads. The method comprises the following steps: selection of fries, cultivation of juvenile fishes, cultivation in growing period, construction of a livestock farm, feeding with daily food, control of daily temperature. According to the culturing method of snakeheads, a greenhouse is adopted for cultivation, so that a small ecological environment which is isolated from the natural environment is formed, and besides, the temperature in the greenhouse is higher than the temperature in the natural environment by 3 to 4 degrees, the feeding time of the snakeheads can be effectively prolonged, the food intake of the snakeheads can be improved, the purpose of shortening the culturing cycle is achieved, the invasion from natural bacteria can be effectively isolated in breeding and occurrence of dead of disease can be reduced due to the fact that the greenhouse is adopted for cultivation.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating snakeheaded fish. Background technique [0002] Snakehead is a rare freshwater fish with high economic value, known as "the treasure of fish"; it is very nutritious and contains a lot of protein, which is higher than that contained in chicken and beef; from the perspective of nutrition, snakehead is a kind of High-grade health food with comprehensive nutrition and delicious meat taste; black fish sells well both at home and abroad, but is expensive. [0003] The existing breeding techniques generally adopt open-air water breeding, which is easily affected by the natural environment, has a long breeding cycle, and has a high mortality rate. Contents of the invention [0004] The purpose of the present invention is to provide a method for cultivating snakeheaded fish in a greenhouse, which can shorten the culturing period and reduce the occurrence of diseases....
