Double-layer three-dimensional sea cucumber inhabitation cage for culture pond

Abstract

The invention discloses a double-layer three-dimensional sea cucumber inhabitation cage for a culture pond. The double-layer three-dimensional sea cucumber inhabitation cage comprises two bottom layer long semi-cylindrical inhabitation cages and a top long semi-cylindrical inhabitation cage, wherein the arc surfaces of the bottom cages face upwards; the arc surface of the top cage faces downwards; three long semi-cylindrical inhabitation cages are connected into a whole; in each long semi-cylindrical inhabitation cage, semi-cylindrical perforated sclerites serving as support pieces are arranged at the intervals 0.5-1.5 meters, the diameters of the semi-cylindrical sclerites are 0.2-0.3 meter, and circular holes of which the diameters are 5 centimeters are uniformly distributed on the sclerites; the sclerites are semi-enclosed into a long semi-cylindrical inhabitation cage by using a strip-shaped narrow fine-mesh knitted mesh; one side of the inhabitation cage is provided with a strip-shaped opening of which the width is 5-8 centimeters for serving as a sea cucumber inlet / outlet; the length of the double-layer three-dimensional sea cucumber inhabitation cage is 30-50 meters; duringarrangement in the culture pond, a plurality of inhabitation cages are arranged from one end of the pond to the other end of the pond in the length direction of the pond by connecting; and the inhabitation cages are arranged at the intervals 2-3 meters in the width direction of the pond. According to the double-layer three-dimensional sea cucumber inhabitation cage, the problem of unreasonable inhabitation structure of the conventional sea cucumber culturing pond suitable for the life habit of sea cucumbers is solved; and the double-layer three-dimensional sea cucumber inhabitation cage is suitable for sea cucumber culturing.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a double-layer three-dimensional sea cucumber habitat cage for pond culture ponds. Background technique [0002] Sea cucumber farming is a new aquaculture industry that has gradually developed in my country's coastal areas in recent years, and the value of aquaculture production has been increasing. Except for a small part of sea cucumber artificial breeding in natural sea areas, most of the rest are distributed in coastal intertidal zone cofferdam ponds and ponds in tidal flats that are suitable for hydraulic conditions. Pond farming currently accounts for 90% of the sea cucumber breeding area in my country. the vast majority. Sea cucumber culture in ponds is a form of aquaculture that has only been developed in recent years. There are various structures and types of ponds. Many of them copy the pond types of shrimp culture to increase sea cucumber culture. The habitat and attachment ...

Problems solved by technology

Sea cucumber culture in ponds is a form of aquaculture that has only been developed in recent years. There are various structures and types of ponds. Many of them copy the pond types of shrimp culture to increase sea cucumber culture. The habitat and attachment structure is built according to the living habits of sea cucumbers. The materials are not reasonable. Most of the sea cucumber habitat and attachment structures are reefs built with stones, bricks and tiles, and old scallop cages and meshes that have sunk into the bottom of the water. These habitats are not very sufficient for sea cucumbers. Cause a certain impact, and remove these habitat structures when cleaning the bottom of the breeding pond is labor-intensive and low-efficiency
