Embodiment 1

[0014] A kind of snakehead culture method that present embodiment provides, breeding area 22 mus, total output 45406 kilograms when dry pond at the end of the year, wherein commercial snakehead 39563 kilograms, silver carp, silver carp 2755 kilograms altogether, grass carp 1657 kilograms, black carp 1431 kilograms. The specific implementation process of the breeding experiment is as follows:

[0015] ①In order to facilitate production management and facilitate various operations, the farms adopt small ponds of 1-1.5 mu for breeding, the depth of the pond is 2 meters to 2.5 meters, and the water depth is maintained at 1.5 meters to 2 meters. The ridge of the pond is more than 0.5 meters above the water surface. It is silty, the bottom of the pond is flat, and there is little silt. The inlet and outlet of the pond are equipped with solid anti-escape facilities. The farm is connected to the river, the water source is sufficient, the water quality is fresh, no pollution, the water...

Abstract

The invention discloses a snakehead fish cultivation method. The technical scheme adopted by the method comprises: creating mimic-ecological pond conditions, executing the tie-in cultivation of multiple fish species, feeding fresh and live baits and pellet feeds, usually regulating the water quality and purifying the water body, and strengthening day-to-day management and disease control; and the method is characterized in that the created mimic-ecological pond conditions are as follows: an area of 1-5 mu is adequate for the area of a cultivating pond, the water depth is 1.5-2m, the ridge of the pond is more than 0.5m higher than the water surface, the dissolved oxygen content is more than 5 mg/L, and the transparency is more than 30cm; and an aquatic weed belt with a length of 1.5-2.0m is transplanted along the edge of the pond. By using the snakehead fish cultivation method disclosed by the invention, a higher yield can be ensured, the cultivating environment can be improved, and the quality of the snakehead fish can be enhanced, thereby increasing the cultivating benefits; and the water quality is effectively improved, the disease incidence rate of fish bodies is reduced, and the quality and benefits of the commercial snakehead fish are improved. The snakehead fish cultivation method disclosed by the invention is universally applicable to the artificial large-scale snakehead fish cultivation for freshwater aquiculture farmers in the middle and lower reaches of Yangtze River and the south of the Yangtze River.

Description

technical field [0001] The invention relates to the technical field of special aquaculture, in particular to a method for cultivating snakehead snakeheads. Background technique [0002] Snakehead, commonly known as black fish, is a rare freshwater fish with high economic value. It is known as the "treasure among fish". Rich in protein, it is a high-grade health food with comprehensive nutrition and delicious meat. Snakefish sells well both at home and abroad. It is delicious, high in price, easy to breed, and has remarkable benefits. Therefore, it has become one of the most popular breeds in recent years. At present, farmers mostly rely on conventional artificial pond breeding. This breeding method has high density, rapid development, and quick results, which greatly alleviates the contradiction between supply and demand in the market. But at the same time, there are also serious defects, which are mainly reflected in the following two aspects: one is the high incidence of...
