Loach seedling growing method

Abstract

The invention belongs to the field of cultivation, and particularly relates to a loach seedling growing method which comprises the following steps: (1) breeding and spawning; (2) placing spawns in a spawning pool for uniform spawning, placing an oxygen increasing rod beside the spawning pool, placing the oxygen increasing rod at the bottom of the spawning pool after spawning, and cultivating young loach seedlings; (3) performing pond cleaning with a pond cleaning chemical, injecting water and fertilizing water after 3 days, and when pool water is cultivated to be yellow green, putting the young loach seedlings in the pond; (4) before the young loach seedlings are placed in the pond, at first, placing the young loach seedlings in an oxygen bag, placing the oxygen bag in pond water for buffering, and then placing the oxygen bag in a net cage; (5) using milk and quail egg yolk as baits to be fed; (6) 7-10 days later, feeding powder. The loach seedlings are grown through the method, the survival rate of the young seedlings is more than 35%, the survival rate of the young seedlings is increased, the density of the spawns is adjusted through the adjustment of the position of the oxygen increasing rod, the workload is reduced, the seedling growing cost is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a method for raising loach seedlings. Background technique [0002] Loach is known as "ginseng in water" for its delicious taste, tender meat and rich nutrition. According to analysis, every 100 grams of loach meat contains 18.4 grams of protein, 2.9 grams of fat, and the content of vitamin B1, A, and C is higher than that of other fish. In addition, loach is mild in nature, sweet in taste, and enters the liver, spleen and kidney. It also has high medical value. Therefore, in recent years, the export trade volume of loach has increased year by year, and the consumption of loach in China has also shown an upward trend. [0003] Since the natural loach resources are far from meeting people's consumption needs, the loach breeding industry has also begun to enter a period of rapid development. The existing loach hatching cultivation method is: place the loach broodstock in the p...
