Tank and cofferdam sea pumpkin breeding device

Abstract

The present invention provides a holothurian culturing apparatus by means of pools and surrounding dams, belonging to the technological field of cultivation. In the apparatus, hollow upright posts and solid ones are arranged at four corners of the apparatus, rims among the posts are connected into a square frame body, and plastic plates provided with via holes at the central position serve as channels for sea cucumbers, wherein the plastic plates are sloping plates among the four upright posts and the rims of the hollow upright posts and solid ones. Structural units having the same structure mentioned above construct a multilayer complex structure body through positive and reverse interactive superposition. Sunlight-transparent plates of light color and light-tight plates of deep color are respectively used for plastic plates at upper part and lower part of the superposition structure. The plastic plates are wave shaped ones or plane ones, are produced by injecting nontoxic materials and superposing a plurality of monomers of same shape, and are easy in lot manufacturing, cleaning and moving. The monomers at the lower part of the apparatus are formed by light-tight plates of deep color, capable of screening and concealing sea pumpkins; the monomers at the upper part of the apparatus are formed by sunlight-transparent plates of light color, capable of growing natural baits for sea pumpkins and bio-membranes for purifying water quality. Then, the apparatus is capable of finding extensive uses in screening and concealing sea pumpkins, producing baits and purifying water quality.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. Specifically relates to a sea cucumber pond and a cofferdam cultivation device. Background technique [0002] Sea cucumber is an important sea cucumber in my country. In recent years, my country's sea cucumber aquaculture industry has developed rapidly. In 2007, the production of sea cucumber aquaculture in Shandong and Liaoning was about 80,000 tons, with an annual output value of more than 15 billion yuan. It has formed another new wave of mariculture after kelp, prawns, scallops and sea fish. [0003] Compared with the rapidly developing scale of sea cucumber aquaculture, its aquaculture technology system is relatively backward, especially the sea cucumber aquaculture device, that is, the selection of the ginseng reef or attachment base is very random and unscientific. Caused great waste, also influenced the raising of breeding output, and will restrict the healthy development of this ind...

AI Technical Summary

Problems solved by technology

Although it is a good shelter for sea cucumbers, its exposed area is limited, which is not conducive to the growth of surrounding organisms, and it is also difficult to move, which brings inconvenience to cleaning the bottom and fishing sea cucumbers

Some sea cucumber farms use clustered plastic hoses as reefs. This kind of reefs is economical, easy to move, and easy to catch and clean. However, it only serves as a shelter and has little effect on cultivating natural bait.
