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 cucumber: Transshipment in August 2020 - a total of 2,560 sea cucumber seedlings (6-8cm) sown at the bottom, counted after the sea cucumber leaves the pool, 40 heads will be placed in a nylon net bag, and then put into the net bag containing 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...

Embodiment 2

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

[0048] ①Transshipment of sea cucumbers: In September 2019, 3,000 sea cucumber seedlings (6-8cm) were transferred. After the sea cucumbers came out of the pond, they were counted and put 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 unpacking, 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 then ...

Abstract

The invention provides a safe transfer and precise bottom sowing integrated method for stichopus variegatus seedlings. The method comprises the following steps that pre-cooled seawater is added into seedling bags in advance; net bags filled with the stichopus variegatus seedlings are put into the seedling bags filled with the pre-cooled seawater, oxygenating is carried out, packaging is carried out, and the seedling bags are transported to a bottom sowing sea area under a constant-temperature condition; and after the water temperature of the sea surface of the bottom sowing sea area where theseedling bags are placed is balanced, the net bags containing the stichopus variegatus seedlings are taken out and placed in floating type net frames, then the net bags containing the stichopus variegatus seedlings are conveyed to a seabed of the bottom sowing sea area, fixing is achieved, net bags openings are opened, and bottom sowing is completed after all the seedlings to be sown climb out. According to the method, stichopus variegatus is transported with water, intermediate links are simplified as much as possible, the air exposure time of the stichopus variegatus is effectively shortened, and the autolysis problem of the stichopus variegatus is solved; according to the integrated process, the appropriate survival temperature of the stichopus variegatus is guaranteed, and the transportation problem caused by the fact that the stichopus variegatus is not resistant to low temperature is solved; and long ropes are used for fixing the net bags during bottom sowing, so that precise bottom sowing is achieved, the damage risk is reduced, and the survival rate of the seedlings is increased.

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...
