Method for recovering coral reef ecologic system and device for adhering juvenile of hermatypic coral thereof

Abstract

The invention discloses a method for recovering a coral reef ecosystem and a reef-building coral larva attachment device thereof. The method for recovering the coral reef ecosystem comprises the following steps: based on a reef-building coral larva attachment technology, the reef-building coral larva attachment device is arranged on a seabed in a coral reef sea area, an artificial attachment substrate is used to induce reef-building coral larvae to attach, and then the artificial substrate attached with the reef-building coral larvae is transplanted to a coral reef degeneration area and is used to recover the coral reef ecosystem. The reef-building coral larva attachment device consists of a supporting net and a supporting frame of the supporting net, the supporting net is provided with a plurality of detachable attachment plates taking pottery clay or ceramic materials as substrates, and the device is suitable for the attachment of the reef-building coral larvae and can perform the next-step transplantation of reef-building corals. The method is an ideal coral reef supplementation and recovery method at present, and can effectively recover ecosystems of corals in large area of coral reef degeneration sea areas.

Description

technical field [0001] The invention relates to a method for restoring the coral reef ecosystem and a reef-building coral larva attachment device dedicated to the method, which can attach the reef-building coral larvae and perform the next step of reef-building coral transplantation. Background technique [0002] Due to the warming of seawater and other reasons, large areas of coral bleaching and death in the world have been caused, and my country's coral reefs are also facing serious degradation. Human intervention is urgently needed for the replenishment and restoration of coral reefs. The traditional supplementary method of coral reef restoration is mainly based on the transplantation of adult reef-building corals, that is, transplanting reef-building corals of suitable size and type to degraded areas to improve the biodiversity of coral reef ecosystems in degraded areas. Such transplantation mainly There are two types: one is to directly collect the whole adult reef-buil...

AI Technical Summary

Problems solved by technology

However, because adult reef-building coral transplantation requires a large number of adult reef-building coral sources, it is easy to spread coral diseases and there are problems such as single transplantation species, it is not suitable for implementation in large-scale degraded areas, and it costs a lot of money, which will cause damage to the donor coral reef ecosystem. a lot of damage
