Problems solved by technology

Among them, sea cucumbers for bottom sowing have higher requirements on the quality of the bottom environment, and because the bottom mud in the cage area contains high concentrations of toxic and harmful substances such as hydrogen sulfide, it is generally not suitable for bottom sowing of sea cucumbers, and sea cucumbers must be removed from the bottom. However, the retention efficiency of the sediments in the sea area is not high by using traditional shellfish culture cages, and the internal space of the culture cages is narrow, which cannot provide enough food and growth space for sea cucumbers

Embodiment 1

[0022] Embodiment 1: Yuzu sea cucumber culture

[0023] From May 26, 2010, the above-mentioned breeding facilities were used to carry out sea cucumber breeding experiments in the Dapengao fish cage culture area of ​​Daya Bay, Shenzhen. The fish cultured in the cage area are mainly cobia, golden pomfret, American redfish and various Grouper, etc., the main bait is chilled small miscellaneous fish, supplemented by matching bait. The sea cucumber cultured in this example is a local common species of Yuzu sea cucumber. The water depth of the culture facilities is 4m, the distance between the culture facilities is 1m, and the average weight of the sea cucumbers used in the experiment is 19.2±2.1g. The water quality indicators during the experiment were: temperature 26.2°C, salinity 32.4, pH 8.2, dissolved oxygen 6.5mg / L. A control group without adding sea cucumbers was set up while sea cucumbers were being cultured to investigate the retention efficiency of the facility on sedimen...

Embodiment 2

[0024] Embodiment two: imitation japonicus culture

[0025] The water temperature in the southern sea area is low in autumn and winter. At this stage, the physiological activities of tropical sea cucumbers slow down, and the sediments intercepted by the cultivation facilities cannot be effectively treated. Moreover, the growth of tropical sea cucumbers is slow at this stage. Using this facility for cultivation cannot obtain higher economic benefits. value. In recent years, the research and production practice of the southern migration of northern sea cucumbers has proved that environmental factors such as water temperature in autumn and winter in the southern sea area are very suitable for the growth of northern sea cucumbers. Therefore, at this stage, this facility can be used to breed high economic value Imitation sea cucumber.

[0026] The results of the examples show that the facility is easy to manufacture and can provide sufficient and suitable habitat space for sea cuc...

Abstract

The invention discloses a sea cucumber culturing facility and a culturing method applicable to a marine net cage culture area. The culturing facility comprises a traction rope, a culturing cage, an internal lining dense net and a heavy object, wherein the culturing cage is hung at the bottom of a net cage through the traction rope; the bottom of the body of the culturing cage is provided with the internal lining dense net; and the heavy object is hung at the bottom of the culturing cage. Through the facility and the method, the sea cucumber can be cultured by means of the space of the marine net cage culture area, so that sediments at the net cage area are effectively treated and extra economic benefit is gained, and a good environment condition is provided for the growth of the sea cucumber while the sediments of the net cage area are effectively intercepted and treated.

Description

technical field [0001] The invention relates to a sea cucumber cultivation facility suitable for seawater cage cultivation areas. The present invention also includes the cultivation method of the cultivation facility. Background technique [0002] In recent years, fish cage culture in the southern waters has achieved vigorous development. While obtaining huge economic benefits, the residual bait, feces and other breeding waste produced during the fish farming process have caused huge pollution to the environment. A large number of studies have proved that sea cucumber can be used as a scavenger of sediment environmental pollution. If it can be cultivated in marine fish cage culture areas, using the characteristics of its sediment feeding habits, it can effectively remove the culture waste in the cage area , and the cultured sea cucumber itself has extremely high economic value. The traditional sea cucumber culture method is to directly sow it on the seabed near the shore, ...
