Abstract

The invention discloses an ecological loach breeding method. The method comprises the following steps of (1) breeding pond building, wherein a breeding pond comprises a waterproof wall, water flea culture ponds, a sewage discharging pit, an insect trap lamp, waterwheel aerators and dissolved oxygen detectors; (2) breeding pond disinfection, (3) bottom culture water cultivation, wherein decomposed faeces and wormcast are applied to the breeding pond, the breeding pond is inoculated against chlorella, Cyclotella stelligera, Cryptomonas and photosynthetic bacteria, and cultivation is conducted for 15-20 days; (4) stocking of loach seedlings and water flea larvae, (5) feeding management, wherein 2-3 days after releasing, the loach seedlings are fed with self-made fodder once in the morning, afternoon and evening respectively every day, when the water color transparency is lower than 10 cm, the water flea larvae are released to the water flea culture pond, when the water color transparency is higher than 20 cm, decomposed faeces and wormcast are added into the breeding pond, and breeding is conducted continuously to obtain loaches. The breeding method has the advantages that no breeding sewage is discharged, the feeding amount of the fodder is low, economical benefits are high and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically the invention relates to a method for cultivating ecological loach. Background technique [0002] Loach, as a famous and high-quality freshwater fish, not only has the characteristics of high protein, low fat, and rich nutrition, but also has fresh and tender meat and delicious taste, so it is very popular in the market. Therefore, the intensive farming of loach is more and more favored by aquatic enterprises. However, the traditional breeding method has the disadvantages of large sewage discharge, low feed utilization rate, and easy deterioration of water body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a loach breeding method with no breeding sewage discharge, less feed and high economic benefit. [0004] In order to solve the problems of the technologies described above, the present invention is ach...
