The invention discloses a breeding method of
snakehead. The method includes the steps of building a
fish pond, wherein the distance between an upper limit
water level sensor and a
lower limit water level sensor of the side wall of the
fish pond is 0.7 m, the distance between the upper limit
water level sensor and the top surface is 0.4 m, and the distance between the upper limit water level sensorand the bottom surface is 2m; building anti-escape walls around the
fish pond; maintaining the content of dissolved
oxygen in pond water at 6 mg per
liter, and maintaining the transparency at 30 cm;planting water floating plants on the water surface in the pond; using a 4%
saline solution for soaking fry for 8 minutes, wherein the
stocking density is 5,500 per mu; feeding the fry at 8 o'
clock a.m and 5 o'
clock p.m every day, wherein the daily feeding amount accounts for 5-8% of the total weight of
snakehead; replacing water once every 15 days, wherein one third of the total water amount is replaced every time; carrying out large-scale water replacement once every one and half month, wherein 85% of the total water amount is replaced every time; carrying out disinfection on the fish pond every 20 days;
fishing out
snakehead with big size from the fish pond
every three months; one and half year later,
fishing out snakehead meeting the sale requirement for sale. According to the method,it is ensured that the snakehead contains abundant
protein and fat, and meanwhile the
survival rate and
growth speed of the snakehead are effectively increased.
