Problems solved by technology

At the same time, after sowing ginseng seedlings directly into the sea, sea cucumbers will be pushed by waves in the water and will collide with reefs, etc., resulting in damage to their delicate body walls and a decrease in their survival rate; The area suitable for bottom sowing will also cause the loss of seedlings, and it is impossible to achieve accurate bottom sowing

Embodiment 1

[0041] An integrated method for safe transshipment and bottom sowing of sea cucumber seedlings, the method is as follows:

[0042] ①Transshipment of sea cucumbers: Transshipment in August 2020 - a total of 2,560 sea cucumber seedlings (6-8cm) sown at the bottom, counted after coming out of the pool, 40 heads in a nylon net bag, and then put the mesh bag into the Pre-cooled seawater seedling bags are packaged and oxygenated, and finally packed in a foam box, and an ice bottle is added to seal the box. The boxed japonicus is transported to the working dock of Wuzhizhou Island by a cold chain vehicle for 5 hours, and then loaded into a transport ship and transported to the bottom sea area.

[0043] ② Bottom sowing of sea ginseng: In order to balance the water temperature, put the seedling bag on the sea surface to balance the water temperature for 20 minutes after opening the box. Then the diver takes out the net bags, bundles every 10 net bags, and puts them into the floating n...

Embodiment 2

[0047] A sea cucumber seedling water transfer bottom sowing method, the method is as follows:

[0048] ①Transshipment of sea cucumber: In September 2019, 3,000 sea cucumber seedlings (6-8cm) were transferred. After the sea cucumber came out of the pool, count them and put them into seedling bags filled with pre-cooled seawater, and then put the seedling bags into foam boxes , seal the box after adding ice. The sealed sea cucumbers are transported to the working dock of Wuzhizhou Island by a cold chain vehicle for 5 hours, and then loaded onto a transport ship and transported to the Dibo sea area.

[0049]② Bottom sowing of japonicus japonicus: In order to balance the water temperature, open the seedling bag after opening the box, pour an appropriate amount of seawater into the seedling bag, wait for about 20 minutes, count the japonicus japonicus into the net bag, and put every 10 net bags into a bundle. Temporarily stored in the floating net frame on the sea surface, and the...

Abstract

The invention provides an integrated method for safe transfer and precise bottom sowing of sea cucumber seedlings, which comprises the following steps: adding pre-cooled seawater into seedling bags; In the seedling bag, oxygenated, packed and transported to the bottom sowing sea area under constant temperature conditions; after the seedling bag was placed on the sea surface of the bottom sowing sea area to balance the water temperature, the net bag containing the sea cucumber seedlings was taken out, put into the floating net frame, and then Send the net bag containing the japonicus seedlings to the bottom of the bottom sowing sea area, fix it, open the mouth of the net bag, and wait for the seedlings to climb out to complete the bottom sowing. The method adopts water-carried sea cucumbers to simplify the intermediate links as far as possible, effectively reduces the air exposure time of sea cucumbers, and solves the problem of autolysis of sea cucumbers; this integrated process ensures a suitable survival temperature for sea cucumbers and solves the problem of The sea cucumber is difficult to transport due to its low temperature resistance; the bottom sowing long rope fixes the net bag, realizes precise bottom sowing, reduces the risk of damage, and improves the survival rate of seedlings.

Description

technical field [0001] The invention belongs to a method for safe transportation and bottom sowing of tropical living sea cucumber seedlings, in particular to an integrated method for safe transfer and precise bottom sowing of sea cucumber seedlings. Background technique [0002] There are many kinds of tropical sea cucumbers, which are the species resource bank for economic sea cucumber breeding and development in my country. Among them, sea cucumbers have high economic value and great development potential. Making full use of the tropical coral reef waters for bottom sowing and breeding of Apostichopus japonicus can significantly enrich the market of marine treasures in my country and cultivate new economic growth points. At present, Apostichopus japonicus has successfully broken through the artificial breeding technology, but there are still many technical difficulties in shallow sea bottom sowing and multiplication, especially the long-distance transportation of seedling...
