Degraded coral reef bioremediation method based on macrocalcified algae

Abstract

The invention discloses a coral reef bioremediation method based on macrocalcified algae. Halimeda sp., Amphiroa sp. and / or crustose coralline algae are planted at the seabed of a coral reef to-be-repaired sea area through three artificial transplantation modes, i.e., a mesh method, a cement plate algal reef method and / or an in-situ reef fixation method. Through three macrocalcified algae transplanting methods provided by the invention, the survival rate of algae can be remarkably increased; meanwhile, the methods are simple, rapid and low in cost and have wide application in the aspects of restoring and maintaining diversity and stability of a coral reef ecological system.

Description

technical field [0001] The invention belongs to the application field of biotechnology, in particular to a bioremediation method for degraded coral reefs based on large calcified algae. Background technique [0002] Tropical coral reef ecosystems are the most biodiverse of all marine ecosystems, and calcareous organisms such as reef-building corals and large calcified algae constitute the main stable and complex physical structures that provide protection for shorelines and help maintain a relatively At the same time, as a natural resource, the coral reef ecosystem can directly or indirectly provide products and services for human production and life. However, under the dual pressures of global climate change and human activities, coral reef ecosystems around the world have begun to degrade to varying degrees, and the coverage of living corals has decreased sharply. Among them, coral reefs in southeastern Asia and the Indian Ocean have the fastest degradation rates; coral re...
