Description
The technical field is as follows:
the invention relates to a method for shipping tropical holothurian seedlings by a flowing water method in high density.
Background art:
the sea cucumber promotes the circulation of benthic nutrient salts by feeding and discharging a large amount of silt, and has important significance for maintaining the steady-state safety of the coral reef benthic ecosystem. In recent years, with the increasing frequency of human activities, the health of the coral reef ecosystem is damaged, the diversity of the coral reef ecosystem is sharply reduced, and the seabed desertification phenomenon even appears in partial areas. The artificial transplantation is an effective way for accelerating the recovery of the biodiversity of the coral reef ecosystem. Sea cucumber is one of important candidate species for bottom sowing and transplanting as an important reef protecting organism.
Holothuria leucospilota (Holothuria leucospilota) belongs to the holothurian (Holothuriidea) of the holothurian family, has the characteristics of wide distribution, strong adaptability and stress resistance, and is one of ideal varieties for releasing and transplanting. Through technical research and development for many years, domestication and large-scale cultivation of wild holothurian leucospilota have been realized by the group, however, the holothurian is very easy to rot and induce collective death with other holothurians in water in the shipping process due to the high-density transferring and transplanting technology in open sea, the survival rate of the open sea shipping cannot be guaranteed, and the quantity of the open sea transplanted holothurian at present cannot meet the demand of population transplanting and proliferation of the holothurian. The invention discloses a method for transplanting tropical reef-dwelling sea cucumbers by far-sea bottom sowing (application number: 201811096002.X), the shipping density is not more than 10Kg/100L of fresh weight of seawater, the operation is complicated during shipping, and the total shipping efficiency still cannot meet the quantity requirement of sea cucumber transplantation.

The invention is realized by the following technical scheme:
a method for shipping tropical Scophiopsis yuzui seedlings by a flow method in high density comprises the following steps:
1) the collected and jejunum-treated sea cucumbers are transported by ships in a deck running water culture system, and meanwhile, the temporarily-cultured sea cucumbers are shaded to prevent the temporarily-cultured sea cucumbers from being directly sunned; the method adopts conventional methods such as a small-sized blower and the like to carry out aeration and oxygen supply, controls the aeration power, prevents the sea cucumber attached to the wall of the barrel from being physically dragged and damaged by violent stirring of the water body, and adjusts the density under the following conditions: a. naturally extending 5-10 cm of sea cucumber seedlings, wherein the density of the sea cucumber transported by ship is 1000-3000 heads per 100L of sea water; b. naturally extending young sea cucumber seedlings with the depth of less than 5cm, wherein the density of transported sea cucumbers per 100L of seawater is 3000-10000 heads; wherein deck flowing water farming systems utilizes the water pump to pump the sea water of 2 ~ 5m under water to deck flowing water farming systems, and the sea water velocity of flow is: changing 100% of temporary culture water for 1 time every 2-6 h, fixing the water intake pipeline of the water pump under water for 2-5m, and protecting the water intake pipeline from being blocked by foreign matters by using a filter screen; the working voltage of the water pump is conventional voltage and can be connected to a ship power system; after the ship reaches a clean open sea, the running water aquaculture system is operated to temporarily culture the sea cucumbers in running water, so that the activity of temporarily culturing the sea cucumbers is kept;
2) after the jejunum is treated for more than 5 days, feeding commercial algae powder and other baits to the sea cucumber larvae and young seedlings, wherein the feeding amount is 1g per day for every 100L of seawater;
3) releasing and transplanting: after reaching the target sea area, collecting seawater seedlings by using a brush with soft hair, and carrying out bottom sowing and releasing according to a conventional method.
The invention has the following beneficial effects: the sea cucumber culture method is characterized in that a sea water pump is installed on a ship without professional equipment for the first time, a running water culture environment is provided for the shipped sea cucumbers, the shipping efficiency of the shipped sea cucumbers is greatly improved, a sea cucumber seedling maintenance method in a high-density shipping process is disclosed, the high-density shipping of tropical pelargonium sea cucumber seedlings is realized, and important technical support is provided for the recovery and recovery of coral reef sea cucumber population resources.
The specific implementation mode is as follows:
the following is a further description of the invention and is not intended to be limiting.
Example 1: method for shipping tropical holothuria leucospilota seedlings in high density by using flowing water method
a. Naturally extending 5-10 cm sea cucumber seedlings, collecting the sea cucumber seedlings by a bare-handed catching method, temporarily culturing the sea cucumber seedlings in a clean seawater culture pond for 1-3 days before shipping, and feeding no bait to ensure that the sea cucumber empties silt in intestinal tracts so as to enhance the stress resistance of the sea cucumber; adopting a dry cooling transportation mode, and carrying out docking transportation to a docking wharf within 15 hours; 3000 sea cucumbers are temporarily cultured in each 100L of seawater, and about 3.00 million sea cucumber seedlings are distributed in 2 500L barrels;
b. the sea cucumber seedlings with the length of less than 5cm can be naturally extended, and the sea cucumber density in every 100L of seawater can reach 3000-10000 heads in a ship. The sea cucumber seedlings with the specification are collected underwater by a soft fine hair brush, are placed in a clean seawater culture pond for temporary culture for 3-5 days to restore the vitality, and bait is not thrown in the period, so that residual bait in intestinal tracts of the sea cucumbers is emptied, and the stress resistance of the sea cucumbers is enhanced; a transportation mode of wet oxygenation and cooling is adopted, namely, the sea cucumbers are immersed in cooling seawater at the temperature of 16-22 ℃, the sea cucumbers are prevented from being overlapped, dissolved oxygen in the cooling seawater is maintained by an air pump or liquid oxygen, and the sea cucumbers are docked and transported to a docking wharf within 15 hours; the number of temporarily-cultured sea cucumbers is below 6000 per 100L of seawater, and about 6.00 million sea cucumber seedlings are distributed in 2 500L barrels.
