Embodiment

[0008] The method of the present invention was tested in March 2008 in the sea cucumber culture pond of Shandong Rongcheng Haodangjia Group Co., Ltd. Put four (each diameter is 40cm, length is 15cm) a group of PVC plastic pipe reefs in a sea cucumber culture pond with an area of ​​30 hectares, and the density is 1 group / m 2 , Subsequent tests have proved that the PVC pipe reef can also be replaced by stones, tiles or hollow bricks, and its effect is similar. A. japonicus was cultured in another pond as a control group. On April 1, 2008, the sea cucumber seedlings with an average body weight of 2 grams were put into the two ponds at a density of 15 per square meter. On June 1, 135,000 jellyfish seedlings with an average umbrella diameter of 6.5 cm were placed in the polyculture pond. On June 15th, 2,250,000 Chinese prawn seedlings with a body length of 2 cm were released. On June 30th, 90,000 jellyfish seedlings were released. On July 15th, another 45,000 jellyfish seedlings ...

Abstract

The invention discloses a method for mainly cultivating a sea cucumber in a pond in a high-yield and high-efficiency poly-cultivating manner. The method is characterized by comprising (1) putting cucumber reefs into a cultivation pond; (2) then putting and cultivating young sea cucumbers in the cultivation pond; (3) putting and cultivating young jelly fish; (4) putting and cultivating young shrimps; and (5) putting and cultivating young escallops. According to the method for cultivating the sea cucumber, manual cucumber reefs are put in advance to promote the formation of edible biomembranes for the sea cucumber, so that the put young sea cucumbers can obtain abundant natural baits; and the aims of high yield, high efficiency and environmental protection are achieved by using the different diets, cultivation water layers and cultivation time of the sea cucumber, the jelly fish, the shrimps and the escallops and putting and cultivating the sea cucumber, the jelly fish, the shrimps and the young escallops in a vertical and time interleaving manner.

Description

technical field [0001] The invention relates to a polyculture method of sea cucumbers, in particular to a high-yield and high-efficiency polyculture method for mainly raising sea cucumbers in ponds. Background technique [0002] In recent years, the scale of sea cucumber farming has continued to expand, and it has become one of the pillar industries of the mariculture industry. Sea cucumbers mainly feed on and use organic matter and nutrients in the bottom mud of the cultured water body. Due to the limited nutrients in the bottom mud of the water body, the further increase in the production of sea cucumbers is restricted. Therefore, some farms have begun to raise sea cucumbers to improve the breeding production, while feeding and breeding may lead to a decline in water quality and the need for external sewage. Society is in urgent need of a sea cucumber breeding method that does not require feeding and can achieve high yield, high efficiency, and environmental protection. ...
