Sea cucumber bottom-sowing culture facility suitable for soft seabed

Abstract

The invention provides a sea cucumber bottom-sowing culture facility suitable for a soft seabed. The facility comprises frameworks, built-in separation nets, built-in dense nets, cuffs, a traction rope, an anchoring object and a marking floater. The frameworks are arranged in parallel and are covered with outer-wrapping netlike clothing, the frameworks are mutually connected to be of a telescopic mesh cage shape, the built-in separation nets for separating each framework into a plurality of culture units are arranged on each framework, the built-in dense net for catching and gathering sea cucumber baits is arranged in each culture unit, cuffs for taking and placing a sea cucumber is arranged on the outer-wrapping netlike clothing of each culture unit, the frameworks on two ends are respectively and sequentially connected with the traction rope and the anchoring object to be fixedly arranged in a seabed, and the marking floater is connected onto one end of the culture facility. Compared with the traditional culture facility, the culture facility provided by the invention is light and convenient, can be compressed, and is convenient for transportation, throwing and management, and the affect from a natural disaster of typhoon and the like is avoided; and by the adoption of the culture facility, the problems of easiness in entrapping by silt, poor culture effect and the like of the traditional culture facility can be solved, particle-like suspended matters in seabed water can be effectively held back as sea cucumber baits, and the survival ratio and the growth rate of the sea cucumber are improved.

Description

technical field [0001] The invention relates to a bottom-sowing cultivation facility for sea cucumbers suitable for soft seabeds, in particular to a long strip-shaped, compressible bottom-sowing cultivation cage for sea cucumbers. Background technique [0002] Sea cucumbers, especially Apostichopus japonicus bottom-sowing culture have high environmental requirements for the bottom of the sea area. Some sea areas with soft seabeds, such as Jiaozhou Bay, can adopt the following methods for bottom-sowing culture. [0003] One is to build sea cucumber reefs on the seabed, that is, before sowing sea cucumbers, a large number of reefs, such as stones, cement reefs, and oyster shell reefs, need to be put into the sea area. This is because sea cucumbers need reefs as shelters. In addition, reefs are also prone to epiphytic algae and bacteria, and various sediments in the intercepted sea area provide high-quality bait for sea cucumbers. Artificial reefs are expensive, and a large pa...

Problems solved by technology

However, the price of hanging cages and net cages is relatively high, and it is impossible to retain a large amount of suspended particles in the water body for sea cucumbers to feed on. It is necessary to manually supplement and feed bait such as kelp; and a large number of fouling organisms gather in the water layer where the facilities are located, so it is easy to hang and raise the facilities during the breeding process. Biofouling and sedimentation by oysters, bryozoans, lime worms, etc. require frequent cleaning, high breeding costs, and high labor intensity; in addition, cages and net cages need to use rafts and floating balls to provide buoyancy in order to be suspended in the water body , rafts and floating balls not only affect the sea area landscape, but are also extremely vulnerable to typhoons, and the disturbance of waves to the facilities will also affect the sea cucumber's feeding
