Description

Coral oosperm collection device

Technical Field

The application belongs to the technical field of marine organism collection devices, and more specifically relates to a coral oosperm collection device.

Background

Coral ecosystems are not substitutable in marine ecosystems due to their high productivity and high biodiversity. But the coral ecosystem is rapidly degraded worldwide due to global warming and environmental deterioration. In order to recover the coral reef ecosystem and recover the ecological function of the coral reef, scientific researchers have adopted a plurality of methods, such as coral transplantation, substrate stabilization, artificial fish reef and the like, but the methods are not suitable for large-scale recovery of the coral reef and have huge cost. At present, scholars propose a method for capturing coral larvae and transferring the coral larvae to a degeneration area, the method is low in cost and quick in effect, the degeneration area can be recovered in a large area in a short time, and the coral larvae providing area cannot be damaged.

The coral is propagated in two ways, which can be roughly classified into sexual propagation and asexual propagation, and the most common way is sexual propagation. A large amount of coral discharges sperms and ova synchronously during the propagation period, and the ova discharged in seawater are fertilized quickly to form fertilized ova. However, coral eggs are floating eggs, float on the water surface, spread with the water flow, and drift to the surrounding sea area along with the water flow during the development period. Some coral larvae float to a proper depth and can not attach to the sea, and the coral larvae can only consume the stored energy to die except being preyed by plankton or fishes. The fertilization rate of coral eggs is extremely low in natural environment, and even fertilization is frequently eaten and drifted to deep sea for loss, so that the survival rate is low. However, the artificial culture method can ensure the number of available coral larvae, so the existing method is to collect coral eggs.

Because the coral ovulates once a year, the seasons of different varieties are not very same, no fixed breeding season exists, each ovulatory time is only short from ten minutes to half an hour, and the ovulatory time is in the evening and drifts along with waves, so that the difficulty in collecting field coral eggs and fertilized eggs is very high, and the artificial squatting point collection is adopted at present, so that the efficiency is low, and the risk is high.
