Trepang intermediate nursing method

Abstract

The invention provides an interim breeding method of holothurians, comprising holothurian cultivation pond selection, pond transformation, throwing of holothurian seedlings and breeding period management; wherein, the mode of the holothurian cultivation pond selection is as follows: a non-leakage pond with 1-1.5 m water storage is guaranteed when a neap tide is selected at middle tide zones or low tide zones; the selected sea area has no pollution, especially oil pollution; the salt content cannot be less than 28 per thousand, and no rivers are poured in; each pond is provided with a head gate and an emptying gate; the mode of the pond transformation is as follows: firstly, a 40-mesh polyethylene net is paved and fixed at the bottom of the pond, which is used for preventing injurious organisms from entering a holothurian breeding zone; then the pond is divided into a plurality of zones by using a bamboo pole to circle the 40-mesh polyethylene net, and the height of the circled net is 3-5cm higher than water surface; at last, artificial holothurian reefs are put in for holothurian perching, food intake and estivation. The method can save energy and labor cost, has convenient management, reduces labor intensity, and can improve breeding rate, which is especially applicable to holothurian seedling cultivation fields without indoor temporary-breeding conditions.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for cultivating sea cucumbers, in particular to an intermediate cultivation method for sea cucumbers. Background technique [0002] At present, the intermediate breeding methods of sea cucumbers in my country are mostly indoor intermediate breeding. In order to achieve the optimum growth temperature of sea cucumbers, water temperature adjustment is required. Most of the methods are heating up boilers or using underground seawater. This method consumes energy and labor, and is complicated to operate and inconvenient to manage. , the labor intensity is high. [0003] How to study a sea cucumber intermediate breeding method, which can save coal, electric energy consumption and labor costs, facilitate management, reduce labor intensity, and improve the breeding rate, especially suitable for sea cucumber nurseries without indoor temporary breeding conditions. This has becom...
