Abstract

The invention discloses a high-density culture method for oriental weatherfish. The method comprises the following steps: (1) building a culture pond, wherein the cross section of the culture pond isa square structure, and the interior of the culture pond is provided with a water insulation wall, waterwheel type aerators, a sewage discharging pit, inhabiting frames, a dissolved-oxygen detector and rotifer cultivation pools; (2) disinfecting the culture pond; (3) preparing a substrate and water, adding decomposed excrement and earthworm feces into the culture pond, inoculating chlorella, cyclotella, and cryptomonas, and cultivating photosynthetic bacteria; (4) freely culturing oriental weatherfish fry and rotifer larvae; and (5) performing feeding management, 2 to 3 days after the orientalweatherfish fry are thrown, feeding the fry with self-prepared fodder every morning, noon and night, and adjusting water color transparency. The culture method provided by the invention has the characteristics of a less sewage discharging amount, a high culture density, relatively stable water quality and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically the invention relates to a high-density loach culture method. 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 amount of sewage discharge, low breeding density, and easy deterioration of the water body. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a loach breeding method with less sewage discharge, high breeding density and relatively stable water quality. [0004] In order to solve the problems of the technologies described above, the present invent...
