Ecological mixed culture method for co-culturing oysters in sea cucumber circle

Abstract

The invention relates to an ecological mixed culture method for co-culturing oysters in sea cucumber circle. The method comprises the following steps: the pond area is larger than or equal to 20 mu and water depth is 2 m or above; sea cucumber seedlings are added, adding specification and density are adjusted according to water depth, a substrate and water change conditions, wherein the adding density is 1,500-3,000 tou/mu when the specification of the sea cucumber seedlings is 40-80 tou/kg; oyster seedlings are added in accordance with density of 50-150 diao/mu, 5-20 adherance/diao and 5-20 seedlings per each adherence; piling is performed on opposite sides of a pond before the oyster seedlings are added, floating ropes are arranged between the two piles on the opposite sides, the distance between the floating ropes is 5-10 m, floating balls are fixed on the floating ropes, one diao of oyster seedlings is hung on the floating ropes at an interval of 50-100 cm, scallop shells are usedas adherance, hanging ropes are 0.5-1.2 m long, and spacing between the adherance is 15-30 cm; water is changed regularly for 10%-30% every time. According to the method, the ecological environment ofthe culture water area can be improved, and the culture yield of the sea cucumbers and the oysters is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological polyculture method for raising sea cucumbers and oysters in traps. Background technique [0002] Sea cucumbers and oysters are important products of mariculture in coastal areas, and their monoculture technology is relatively mature. Using a single sea cucumber culture requires many manual operations and difficult water quality control. At the same time, due to the continuous high temperature in summer, captive sea cucumbers suffer from hypoxia and skin peeling, resulting in large-scale deaths. The risk of sea cucumber breeding increases, and the cost of breeding continues to rise. Therefore, it is necessary to implement a polyculture model of sea cucumbers and oysters. By rationally matching the number of sea cucumbers and oysters, oysters are used to feed and purify seawater. At the same time, aquatic plants attached to ropes and shells not only increase diss...

Problems solved by technology

Using a single sea cucumber culture, there are many manual operations, and the water quality control is difficult

At the same time, due to the continuous high temperature in summer, captive sea cucumbers are hypoxic and peeled off, resulting in large areas of death. The risk of sea cucumber breeding increases, and the cost of breeding continues to rise.
