Embodiment Construction

[0012] Below in conjunction with specific embodiment the technical scheme is further described as follows:

[0013] 1. Breeding conditions

[0014] The ponds are all rectangular, running from east to west, with an area of ​​2 to 8 mu and a water depth of 1 to 1.5 meters. The bottom of the pond is flat, the soil is loam, the bottom silt is less than 10cm, the water source is sufficient, the water quality is good and pollution-free, and the drainage and irrigation are convenient. One 2.2 kilowatt inflatable oxygen pump is installed.

[0015] 2. Preparation before stocking

[0016] Clean up the pond and remove excess silt from the bottom of the pond. One week before stocking, and 15 days before stocking, the parent pool will be thoroughly disinfected. Keep the water depth in the pool at 8-10cm, pour 150kg of quicklime per mu into the whole pool evenly while it is hot, and rake the bottom mud the next day to improve the disinfection effect. After being exposed to the sun for ...

Abstract

A paramisgurnus dabryanus fry breeding technology comprises the following steps of stocking in a parent pool: firstly building a special parent pool, performing thorough disinfection before stocking, then, selecting young paramisgurnus dabryanus of which the size is basically the same, and putting the selected young paramisgurnus dabryanus into the parent pool for breeding. Strengthening breeding: feeding artificial compound feed on the basis of provision of natural fish bait, adjusting the usage amount of the feed according to the conditions at intervals, frequently observing the change of water quality during the breeding process, and changing water one time per week in general. Then parents are selected for induced spawning, and suitable physique and maturity of parent fishes are selected. Then artificial propagation, natural spawning and fertilizing are performed, and then fertilized ova are collected and hatched into fries in circular hatching channel slow flowing water. Stocking fries can be selected for breeding according to the pool area, the number of the fries, estimated output and the like.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to the seedling breeding technology of yellow eelfish. Background technique [0002] Paraloach with large scales, commonly known as yellow loach, belongs to Cyprinidae, Loachidae, Anthrophyla subfamily, and Paraloach genus. The common species of loach in our country are Paraloach, green loach and gray loach. Among them, Paraloach is the largest and grows the fastest. In the northern region, seedlings with a body length of 3 to 5 cm are placed in the spring for artificial breeding, and the average size of adult loach can reach about 20 g / tail by the end of autumn. [0003] During the cultivating of yellow platefish seedlings in the prior art, there are many deficiencies in aspects such as the environment required for each breeding, the nutrition required for each growth stage of yellow platefish, and the habitat in the breeding process. These defects not only affect the yellow platefish. ...
