Floating three-dimensional device for culturing coral in seawater

Abstract

Disclosed is a floating three-dimensional device for culturing coral in seawater. The device comprises a floating body, a connecting body and a floating body connector, and the connecting body is arranged in the seawater; the connecting body comprises a connecting object and a base; the floating body is connected with the connecting object; the connecting object is provided with the base; the baseis fixedly provided with the coral. The device can be not only used for the ultra-large-scale culture of the coral but also used as attachment land for some bacteria, algae and the like in a marine ecosystem or provide a habitat place for other organisms such as certain zooplankton, the growth surface area of marine organisms is increased, and the device has important ecological significance; thedevice can also be used for adjusting the materials and numbers of all parts according to actual conditions, all the parts can be freely combined into different configurations, and the device has high applicability.

Description

technical field [0001] The invention belongs to the technical field of marine organisms, and in particular relates to a floating three-dimensional coral cultivation device in seawater. Background technique [0002] Coral reefs are an important part of the marine system and an indispensable ecosystem for the planet. However, in recent years, with the deterioration of the global ecology, coral reefs have severely declined, and my country's sea areas have not been spared. Increased sea temperature, ocean acidification caused by the greenhouse effect, seawater pollution, and enhanced ultraviolet radiation are all important factors that cause coral reef degradation. [0003] At present, the culture method about coral mainly contains: (1) coral transplantation: the coral of collecting healthy coral reef area is transplanted to degraded coral reef area. However, the loss of coral reefs during the transplantation process may be more than the output, and the results are often not w...

AI Technical Summary

Problems solved by technology

However, the loss of coral reefs during the transplantation process may be more than the output, and the results are often not worth the candle; (2) gardening coral cultivation: in the laboratory or in a specific sea area, coral fragments or larvae are cultivated, and when the coral grows to a certain size , and then transplanted to the bottom of the degraded coral reef area, this method helps the transplanted corals adapt to the new environment and reproduce, but this horticultural farming method is limited by the cultivation environment and transplantation process, the growth and reproduction efficiency of corals Low, heavy workload, not suitable for large-scale cultivation of corals and reconstruction of coral reefs in real marine environments

Large-scale reproduction of corals and reconstruction of coral reefs are worldwide problems. The laboratory can obtain a small number of coral embryos or fertilized eggs, but cannot effectively reproduce coral larvae
