Embodiment 1

[0031] Embodiment 1 first fully introduces the structure of the coral larva directional bottom sowing device used in the present invention, as figure 1 As shown, the directional bottom sowing device for coral larvae includes an upper container 1, a draft tube 2 and a bottom cover net 3, wherein the upper container 1 is arranged above the bottom cover net 3, and the upper container 1 passes through the draft tube 2 and the bottom cover net 3 connect.

[0032] Its specific usage principle is as follows:

[0033] Before sowing the coral larvae at the bottom, first make the bottom cover net 3 tightly cover the attached reef to isolate the interference of external organisms, then use a scoop to carefully scoop the coral larvae close to the upper container 1, and slowly put the coral larvae into the upper container 1. At this time, coral larvae rely on water pressure or self-weight to flow into the bottom cover net 3 through the upper container 1 and the diversion tube 2, and dispe...

Embodiment 2

[0041] The present embodiment adopts the device described in embodiment 1 to carry out a coral larva directional bottom sowing, and its specific process is as follows:

[0042] 1. The source of coral larvae

[0043] Coral fertilized eggs are hatched indoors, and after cultivation, floating larvae are formed. During the planktonic stage, the larvae are quickly transported to the bottom sowing site for bottom sowing.

[0044] 2. Bottom broadcast time selection

[0045] The suitable time for directional bottom sowing of coral larvae is from April to June, because most of the corals spawn during this period, and the water temperature is suitable to increase the survival rate of larvae.

[0046] 3. Bottom broadcast site selection

[0047] Choose a sea area with gentle terrain, less suspended matter, high transparency of seawater, abundant light, no industrial discharge pollution and rich bait for bottom sowing. The bottom sowing site is preferably located near similar coral reefs...

Abstract

The invention relates to a method for directional bottom sowing of coral larvae, comprising the following steps: S1. From April to June, select a batch of coral fertilized eggs to hatch indoors, and form floating larvae after cultivation; S2. Select environmental conditions suitable for floating larvae The living sea area is the bottom-seeding sea area, and then the attached reef is put into the bottom-seeding sea area 15 days before the bottom-seeding sea area; Higher than the sea surface; S4. Transport the floating larvae to the bottom sowing sea area, then use a scoop to carefully scoop the floating larvae close to the upper container, and slowly put the coral larvae into the upper container. At this time, the floating larvae rely on water pressure or their own weight to pass through the upper end Containers and diversion pipes flow into the bottom net, and spread out in the independent space of the bottom net, and then attach to the attached reef.

Description

technical field [0001] The invention belongs to the technical field of stony coral breeding and relates to a novel method for directional bottom sowing of coral larvae. Background technique [0002] Coral polyp belongs to a kind of marine coelenterate, which is cylindrical and has tentacles. It lives in the equatorial and tropical or subtropical shallow sea areas with an average temperature above 20°C. It can continuously secrete calcium carbonate bone from the surroundings on the calcareous remains of the previous generation of coral polyps. Stacked in turn to form colorful coral reefs. Among the more than 6,100 kinds of coral polyps found at present, about 500 kinds are reef-building corals. The coral reef ecosystem is called the underwater tropical rainforest. It can not only increase the biodiversity of the sea area, indirectly increase the fishery output, but also accelerate the expansion of the coastline and protect the coast from seawater erosion. Its role in the mar...
