A kind of multi-layer trough type imitation japonicus cultivation method

Abstract

The invention provides a multi-layer groove type apostichopus japonicus breeding method. The method is characterized by comprising the steps that a breeding workshop is selected to be in an area with good ecological environment, and a multi-layer groove type breeding container is built so as to greatly improve the unit area apostichopus japonicus yield, lower production cost and improve production efficiency; a water inlet and a drainage opening are formed in the diagonal lines of each groove layer respectively, and a substratum is arranged in each groove layer; stocking is carried out on apostichopus japonicus seedlings of the specifications of 10g-50g / seedling for breeding, and the seedling releasing density is 1.5 kg / m<2>; an intermitted microflow water or short flow water breeding method is adopted, bottom cleaning is carried out once every seven to ten days, groove pouring is carried out once every 20-30 days; sea mud, algae powder and mixed feed are fed as main materials, plant source immunopotentiator is added for mixing feeding, feeding is carried out once every one to two days, and the feeding amount is three percent to ten percent of the weight of apostichopus japonicus and is adjusted according to the size of the apostichopus japonicus, water temperature, the ingestion conditions and the amount of residual feed; microecologics is applied regularly to adjust and control water quality to prevent diseases.

Description

technical field

[0001] The invention relates to seawater culture technology, in particular to a method for cultivating imitation japonicus japonicus in multi-layer tanks. Background technique

[0002] The factory farming of imitation japonicus is a farming method that utilizes breeding facilities built in areas with underground seawater resources and artificially controls environmental conditions such as water temperature, dissolved oxygen, salinity, and water quality. At present, most of the industrial imitation japonicus breeding facilities in northern my country are transformed from the original workshops for breeding flounder and flounder. The walls are made of bricks, the roof is a steel beam support, and the upper layer is covered with 1-3 layers of ethylene-acetic acid Ethylene copolymer (EVA) shed film, the cement pool is generally 6m x 6m in size, and the water depth is about 1m. In the pool, use mesh cages, large plastic basins, and special corrugated board frames f...
