Embodiment 1

[0022] a, before the spawning period, select 200 species of ginseng with a ginseng age of 3 years and an individual weight of 150g, and put them in the cultivation pond; b, the area of ​​the cultivation pond is 23㎡, and the depth of the water in the cultivation pond is 50cm. The temperature of the water in the inner pool is controlled at 18°C, the salinity is 35‰, and the pH is 8.0; the 24-hour uninterrupted water cultivation mode is adopted in the cultivation pond, and the daily water exchange volume in the cultivation pond is 23m³; 12 attachments are put into the cultivation pond Base, the attachment base is spliced ​​by pipe body, and the pipe body is made of acid, alkali and anti-corrosion PVC pipe. The length and width of each attachment base are 50cm, and the height is 24cm; when feeding, add appropriate amount of water to the powdery bait Stir evenly and make small balls with a diameter of 1.8cm to 2.2cm for multi-point feeding.

Abstract

The invention relates to the technical field of aquatic product breeding, in particular to an indoor oversummering method for juvenile apostichopus japonicus. The method comprises the steps of selection of juvenile apostichopus japonicus, control of water quality indexes, feeding of an attachment substrate and adoption of a flowing-water cultivation mode. By the indoor oversummering method for thejuvenile apostichopus japonicus, the juvenile apostichopus japonicus can pass summers indoors, the death rate of the juvenile apostichopus japonicus is reduced, a good foundation condition is provided for genetic breeding, long-term monitoring of the juvenile apostichopus japonicus and acquisition and collation of data in breeding operation are facilitated, and the quality of propagation of apostichopus japonicus is ensured.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to an indoor oversummer method for imitation japonicus species. Background technique [0002] The rapid development of the sea cucumber breeding industry has greatly stimulated the development of the sea cucumber seed breeding industry. The production of sea cucumber seedlings requires a large number of seed cucumbers every year. Due to the growth environment, the wild sea cucumbers that grow in natural sea areas not only have a longer sexual maturity time than artificial ponds. The breeding is late, and the gonad development is not synchronized. Therefore, at present, most of the seed ginseng used in the production of sea cucumber seed comes from artificial pond culture, and the source range of seed ginseng is relatively narrow. It is an indisputable fact that disordered inbreeding among sea cucumber populations leads to the decline of germplasm status. The c...
