Near-shore cultivating and breeding method and device suitable for dendroidal Hermatypic coral

Abstract

The invention discloses a near-shore cultivating and breeding method and device suitable for dendroidal Hermatypic coral. The method comprises the steps of: fixing a dendroidal Hermatypic coral attaching device onto flat reef bottom or gravel bottom at the seabed of a shallow and near-shore sea area with water depth of 2-10 m at the time of low tide, wherein the dendroidal Hermatypic coral attaching device comprises an attaching frame and a supporting rack thereof, multiple attaching strips are arranged in the attaching frame, and multiple attaching branches are fixed on the attaching strips; and binding the dendroidal Hermatypic coral to the attaching branches in a ramification manner, so that the dendroidal Hermatypic coral grows in the ramification manner 15-20 cm away from the seabed. As compared with dendroidal Hermatypic coral subjected to traditional cement block transplanting, the dendroidal Hermatypic coral cultivated by the near-shore cultivating and breeding method suitable for dendroidal Hermatypic coral has the advantages of low mortality, high survival rate, higher growth rate and more healthy coral condition.

Description

Technical field: [0001] The invention relates to artificial restoration technology of coral reefs, in particular to a method and device suitable for nearshore cultivation of branched reef-building stony corals. Background technique: [0002] Coral reefs are the "tropical rain forests" in the ocean, providing habitats and shelters for marine life, and are important ecosystems in the ocean. Since the 1970s, coral reefs have been affected by human and environmental changes, and a quarter of coral reefs have been completely destroyed. Therefore, reef-building coral restoration technology has become an important hope for slowing down coral reef degradation and accelerating coral recovery. [0003] The artificial restoration of coral reefs now mainly relies on the asexual reproduction of corals, and the purpose of restoring the number of damaged coral reefs is achieved by transplanting individual corals or cultivating small individual corals. Using this method to restore coral re...

However, most of these cultivations and transplants are carried out in sea areas with transparent water quality and low wind and waves, or in deeper sea areas, and there are few examples of transplanting and cultivation in nearshore water bodies with frequent human activities and a lot of sediment.
