Three-dimensional temporary cultivation device for long-distance transportation and relay cultivation of coral larvae and broken branches

Abstract

The invention discloses a three-dimensional temporary cultivation device for long-distance transportation and relay cultivation of coral larvae and broken branches. The three-dimensional temporary cultivation device comprises a water-containing box body fixedly arranged on a deck of a transportation ship, wherein a cover plate for controlling the illumination intensity inside the box body is arranged on the top of the box body; a plurality of fixed hanging carrying frames arranged at fixed intervals are arranged at the bottom inside the box body; a plurality of hanging holes are formed in eachhanging carrying frame; a plurality of upwards extending hanging elements used for accommodating the coral larvae or broken branches are arranged on the hanging holes; and water inlet holes and wateroverflow holes used for water circulation inside the box body are arranged in the box body. The three-dimensional temporary cultivation device for long-distance transportation and relay cultivation of coral larvae and broken branches has the advantages that the hanging carrying quantity of corals is great; the moving and dissociation of the corals are convenient; large-scale operation on the shipor in the field is convenient; no damage can be caused on the corals; the coral loss in the transportation period can be effectively reduced; the survival rate is improved; the three-dimensional temporary cultivation device can also be used for laboratory or shore-based medium-or-short-term coral cultivation; and the design structure and the manufacturing material have the characteristics of adjustable inside space, high utilization rate, marine transportation applicability, high structural intensity, impact resistance, corrosion resistance and the like.

Description

Technical field [0001] The invention relates to the technical field of long-distance transportation of coral larvae and broken branches, in particular to a three-dimensional temporary rearing device for long-distance transportation and relay cultivation of coral larvae and broken branches. Background technique [0002] Coral reefs are the most beautiful and moving among the beautiful and vast undersea gardens. The South China Sea island reefs with reef-building corals as the main body are an important guarantee for my country's maritime sovereignty, and also a treasure house of precious marine biodiversity and biologically active substances. It has very important ecological, economic and national strategic security values. The restoration practices of degraded coral reefs can be roughly classified into passive restoration or active restoration. Analyzing the passive restoration measures adopted globally, there are imperfect coral reef management behaviors, failure to determine t...

AI Technical Summary

Problems solved by technology

Most of the coral reef ecosystem restoration work needs to be carried out on islands and reefs far away from the coast. In order to reduce the artificial pressure on natural reef areas, it is necessary to use artificial breeding corals for ecological restoration work.
