A sexual reproductive system for corals

Abstract

A coral sexual propagation system relates to the marine organism artificial breeding technology, and is provided with a coral incubator, an alga incubator, an alga screen and a pipeline system, wherein the coral incubator is provided with a main cylinder body, a bottom cabinet and a main cylinder LED lamp; the alga incubator is provided with a filtering cylinder body and a metal halogen lamp; the pipeline system is provided with a pipe network, a water pump, a temperature control device and a wave making device; the main cylinder body is arranged at the top of the bottom cabinet, the main cylinder LED lamp is arranged above the main cylinder body, a pipeline, a grid plate, a lower silk cover layer, a coarse sand layer, an upper silk cover layer and a coral sand layer are arranged at the inner bottom of the bottom cabinet from the bottom up, holes are formed in the pipeline, water in the main cylinder body and the filtering cylinder body enters the alga screen through the pipeline system to realize internal circulation of seawater, and the water pump, the temperature control device and the wave making device are connected through the pipe network and mounted in the main cylinder body; the water pumping end of the water pump is connected with the pipeline at the inner bottom of the bottom cabinet, and the water outflow end of the water pump is connected with the temperature control device and the wave making device. The coral sexual propagation system is simple in structure, smart in design and convenient to operate.

Description

technical field [0001] The invention relates to a technique for artificial breeding of marine organisms, in particular to tropical shallow-water corals, especially a sexual reproduction system for reef-building corals. Background technique [0002] Due to continuous population growth in coastal areas, rapid socio-economic development, and global climate change (abnormally high and low temperature) and other man-made and natural pressures, the coral reef ecosystem has been seriously disturbed and destroyed. degradation. For example, an unusually high temperature increase in 1998 killed about 16 percent of the world's coral reefs. According to a 2008 assessment by the Global Coral Reef Monitoring Network (GCRMN), 19 percent of the world's coral reefs have been severely damaged beyond repair. Without effective management, 35% of coral reefs will disappear within the next few decades. [0003] At the same time, the development of the ornamental aquarium industry, especially t...

AI Technical Summary

Problems solved by technology

However, the needle-brush water pump in the protein skimmer described in this patent, as well as the main water pump and wave-making pump of the system will affect the sperm, eggs, and fertilized eggs in the water body released by planktonic animals, plants, and corals during the reproductive period in the system. , plankton larvae cause mechanical damage

On the one hand, the corals in the system cannot supplement food or organic carbon sources other than photosynthesis through filter feeding, and at the same time, the mortality of eggs and plankton larvae produced by sexual reproduction of corals is high, so it is not suitable to use this system for corals. sexual reproduction

Moreover, in terms of system structure, there are significant differences in the system structures of the two patents, except that both use live rocks as landscaping and inorganic nitrogen treatment tools
