Embodiment Construction

[0020] To implement the present invention, taking the Jianghan Plain area as an example, the following steps can be performed:

[0021] (1) Selection and cultivation of parents:

[0022] ①The choice of parents: the breeding eel parents should select the 2nd-year-old individuals obtained by artificial breeding, and the yellow spot eel with sparsely distributed spots on the body surface is suitable;

[0023] ② Parental cultivation:

[0024] Parent breeding for imitation ecological reproduction is divided into 3 stages;

[0025] The first stage is from July to November of the current year. The cultivation method at this stage is: use pond cages to cultivate, and the parent stocking density is 2~5kg / m 2 , The feed is a mixture of animal bait and compound feed; the ratio of wet weight of animal bait to dry weight of compound feed is 4 to 5:1, and the animal bait is water worm, earthworm or silver carp; the daily feeding amount is 8 of the weight of the rice field eel. %~10%; When the water ...

Abstract

The invention relates to a method for artificially bionic breeding of monopterus albus fries and belongs to the technical field of scientific application of fishery. The method is characterized in that on basis of natural ecological environments and conditions of breeding of monopterus albus, technical means of arranging of a bionic breeding net cage, breeding and overwintering management of breeding parents in advance, controlling over sizes and male-female proportion of the breeding parents and breeding and incubation of monopterus albus under bionic conditions are applied, the reproductive performance of the monopterus albus is improved, and large-batch high-quality monopterus albus fries can be provided for large-scale breeding of the monopterus albus. By means of the method for artificially bionic breeding of the monopterus albus fries, the monopterus albus breeding rate reaches 80%-90%, the incubation rate of natural oviposition and fertilizing can reach above 98%, the fries collecting rate can reach above 95%, and the application prospect is excellent in terms of large-scale breeding of monopterus albus fries.

Description

Technical field: [0001] The invention relates to a method for artificially imitating ecological reproduction of rice field eel seed, which belongs to the technical field of fishery science application. Background technique: [0002] Monopterus albus (Monopterus albus) farming has developed rapidly in my country in recent years. Farming production areas have spread all over the country. In Hubei, Hunan, Anhui, Jiangxi, Zhejiang and other provinces in the middle and lower reaches of the Yangtze River, monopterus albus has become an important breeding species. [0003] However, in the rapid development of the rice field eel breeding industry, the seed has become a bottleneck for its development, and manual batch breeding is needed to produce the rice field eel seed. However, due to the special reproductive biology of the rice field eel, the artificially induced spawning method of bulk fish for seed reproduction is not feasible in production. It is necessary to find a method suitable f...
