Problems solved by technology

The sales season for finished farmed loach is from November to March of the next year. During this period, the price of commercial loach is the highest. However, due to the cold weather during this period, the loach is in a hibernation state, hidden in the mud and inactive, so it is very difficult to catch.
Although methods such as adding water and changing water are generally adopted, the return rate is still very low, often less than 50% of the total output

Embodiment 1

[0016] Choose metal as the frame and high-quality nylon mesh as the mesh surface to make a 10m 2 , a cage with a height of 1.5m and a mesh of 0.5cm with a metal panel on the bottom surface, laying soil with a height of 10cm on the bottom surface of the cage, and placing the cage in a non-polluting pond, river ditch, reservoir, lake or Carry out soaking box and disinfection in the water body of paddy field cultivation, select 5-7cm loach seedlings in May, put the seedlings in 3% salt water and soak for 5 minutes, carry out the surface disinfection of seedlings, and then use 200 tails per square They are stocked in net cages; feeding is mainly based on artificial compound feed, and feeding is increased or decreased according to the loach's food intake, the water quality in the net cages is regularly tested, preventive disinfection is carried out regularly, and the net cages are repaired in time.

Embodiment 2

[0018] Choose metal as the frame and high-quality nylon mesh as the mesh surface to make a 50m2 2 , a cage with a height of 2m and a mesh of 1cm with a metal panel on the bottom surface, laying soil with a height of 20cm on the bottom surface of the cage, and placing the cage in a non-polluting pond, river ditch, reservoir, lake or paddy field in February for cultivation Carry out soaking box and disinfection in the water body, select 5-7cm loach seedlings in May, put the seedlings in 3% salt water and soak for 8 minutes, carry out seedling body surface disinfection, then put in a suitable place to breed with 300 tails per square. In the net cage; feeding is mainly based on artificial compound feed, and the feeding is increased or decreased according to the intake of loach, the water quality in the net cage is regularly tested, preventive disinfection is carried out regularly, and the net cage is repaired in time.

Abstract

The invention relates to a method for culturing mud fish by using a net cage, and relates to the technical field of mud fish raising. The method comprises the following steps of: manufacturing the net cage by taking metal as a frame and high-quality nylon net cloth as a net surface; paving soil on the bottom surface in the net cage; putting the net cage into a culture water body to perform the operation of net cage soaking and disinfection in January or February; selecting mud fish offspring seeds of 5 to 7 centimeters in May; and disinfecting the mud fish offspring seeds, and putting the disinfected mud fish offspring seeds into the net cage. The method has the advantages that the recapture rate is improved greatly and the labor cost is reduced effectively; and the mud fish can be supplied in time aiming at market demands, the economic benefit of farmers is improved obviously, and accurate data is provided for daily management and the study of culture.

Description

technical field [0001] The invention mainly relates to the technical field of loach breeding, in particular to a method for cultivating loach in net cages. Background technique [0002] Loach is a fish with high nutritional value. It is different from other fish in terms of appearance, body shape and living habits. It is a special fish and can be used as medicine. [0003] In the breeding process of loach, the common farming models include paddy field farming and pond farming. The sales season for finished farmed loach is from November to March of the next year. During this period, the price of commercial loach is the highest. However, due to the cold weather during this period, the loach is in a hibernation state, hidden in the mud and inactive, so it is very difficult to catch. . Although methods such as adding water and changing water are generally adopted, the return rate is still very low, often less than 50% of the total output. Therefore, according to this characte...
