Embodiment Construction

[0033] Below in conjunction with embodiment describe in detail:

[0034] 1. Construction of eel pond-cage ecosystem

[0035] At the beginning of April 2013, a pond of 4.5 mu was selected, and the pond was thoroughly cleared with 100-150 kg / mu of quicklime. After clearing the pond, 5-7 days after the pond was cleared, bamboo poles were inserted and pilings were set up to set up cages (each cage for eel breeding was 6m 2 , 3m long, 2m wide, and 1m high), set up in 4 rows, with 25 net cages in each row, and a total of 100 net cages; each net cage is fixed with 4 bamboo stakes, and the upper and lower outlines of the net cages are fixed on the bamboo stakes Above, the draft of the net cage is 70cm, and the water surface is exposed to 30cm; after the net cage is set up, 200kg of fermented cow dung is applied per mu to cultivate the water quality, and the water quality should not be too fertilized; Water peanuts, water peanuts cover 80% of the net cage area; carp, silver carp, bigh...

Abstract

The invention discloses a finless eel pond-net cage ecological culture method, and belongs to the technical field of aquaculture. The method includes the steps of (1) finless eel pond-net cage ecological system construction including A, pond preparation, B, net cage arrangement, C in-cage ecological treatment and D, pond ecological treatment; (2) finless eel breeding; (3) food habit domestication and bait feeding; (4) daily management; (5) finless eel catching. Compared with the prior art, the method has the advantages that a pond-net cage ecological system is successfully constructed by utilizing biological characteristics and feeding habits of several kinds of cultured fishes, net cages need not to be scrubbed frequently, and manual labor force is saved; frequent water transfer is not required, culture expenditure is saved; the finless eel are low in morbidity, less in drug use, high in survival rate, high in quality and good in taste; meanwhile, considerable profit is obtained from polyculture fishes.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a rice field eel pond-cage ecological cultivation method. Background technique [0002] For a long time, there are three main methods of artificial breeding of rice field eels: pond culture, paddy field culture and net cage culture; [0003] Cage culture eels have high density, high yield, convenient feeding and easy catch. However, there are still many deficiencies in the current eel cage culture process: [0004] 1. The mesh is easy to store, the water exchange volume inside and outside the box is small, it needs to be cleaned frequently, and the labor intensity is high; [0005] 2. The residual bait and excrement of rice field eels will accumulate in the cages, which will produce unpleasant smell after corruption, which is not conducive to the growth of rice field eels, and even die in large numbers; [0006] 3. The enrichment of nutrients makes the whole po...
