Embodiment 1

[0015] The far seabed transplanting method of yuzu sea cucumber, the method comprises the following steps:

[0016] 1. In mid-August 2016, 4,729 wild sea cucumbers with 3-6cm in diameter (small sea cucumbers) and 1,824 sea cucumbers with 10-15cm in diameter (big sea cucumbers) were collected in Daya Bay, Shenzhen. Put seawater in the container, put the grid frame in the sea water, put the collected sea cucumbers in the grid frame for temporary cultivation, the sediment discharged during the process of sea cucumber jejunum can leak out through the grid, so that the sea cucumber will not Re-feed the excrement such as sediment, and the sea cucumbers stop excreting after 3 days; during the treatment of the jejunum, change the water 3 times a day, each time the water volume reaches more than 100%, keep the water clear and not turbid, and clean the bottom sediment in time to achieve the effect of the jejunum; Remove the 356 small individual sea cucumbers and 93 large individual sea ...

Abstract

The invention discloses a tropical reef-dwelling sea cucumber high sea bottom sowing and transplanting method. Through operation of key links such as early intestine emptying treatment, connection andtransshipment, ship transportation maintenance and bottom sowing and releasing, large-scale autolysis and death of sea cucumbers in the process of high sea transshipment can be avoided, large-scale high sea bottom sowing and transplanting for the tropical reef-dwelling sea cucumbers can be realized, the biological resources of the sea cucumber population in tropical coral reefs can be restored, the benign development of the coral reef benthic ecological environment is facilitated, and a technical support is provided for steady-state health of the tropical coral reef benthic ecosystem.

Description

Technical field: [0001] The invention belongs to the technical field of coral reef biological transplantation, and in particular relates to a method for sowing and transplanting tropical reef-dwelling sea cucumbers in the far sea. Background technique: [0002] Sea cucumbers inhabit mid-tide or high-tide areas in intertidal zones, coral reef areas, mud or sand, and are one of the important coral reef organisms. Sea cucumbers digest and absorb some organic matter by eating and excreting sediment in large quantities, and play the role of seabed scavengers, which can promote the cycle of nutrients in the benthic environment, and have important ecological value in the coral reef benthic ecosystem. In recent years, with the increasingly intensified and frequent human activities, the health of the coral reef ecosystem has been threatened, the biodiversity of coral reefs has declined sharply, and some areas have even experienced seabed desertification. Artificial bottom seeding tr...
