Stereoscopic sea cucumber hanging breeding facility and composite breeding method

Abstract

The invention discloses a simple stereoscopic sea cucumber hanging breeding facility and a breeding method which are suitable for shallow sea breeding areas or deep ponds. The breeding facility comprises a plank floating bridge, foam floats, a breeding mesh cage, a lining net, a spare mesh cage and dropping stones. The breeding mesh cage is hung on the floating bridge through hooks. The lining net is fixed into the breeding mesh cage in an inclined mode and faces sunlight. The spare mesh cage is placed on the floating bridge to be exposed in the sunlight for standby use. The dropping stones are hung at the four corners of the breeding mesh cage. According to the stereoscopic sea cucumber hanging breeding facility and the breeding method, water-layer particulate organic matters and water-layer sediment intercepted by the breeding mesh cage are fully used for providing natural high-quality bait for sea cucumbers, good environment is provided for the sea cucumbers, other living bodies such as prawns can be bred in a mixed mode at the same time, and therefore a stereoscopic ecological breeding mode is realized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a three-dimensional sea cucumber hanging culture facility and a culture method. Background technique [0002] With the rapid development of northern japonicus aquaculture, japonicus aquaculture has become the largest marine aquaculture industry in northern my country. However, the scale of tidal flat cultivation of japonicus currently used tends to be saturated due to the occupation of a large amount of land resources, and the aquaculture efficiency in tidal flat ponds is low, the survival rate of japonicus japonicus is not high, and it is greatly affected by the external environment. Moreover, sea cucumbers have high requirements on the substrate environment, especially in summer, when the bottom of the pool is prone to lack of oxygen, and harmful substances such as hydrogen sulfide produced at the bottom cause a large number of sea cucumbers to die. Therefore, ...

Problems solved by technology

However, the scale of tidal flat cultivation of japonicus currently used tends to be saturated due to the large amount of land resources occupied, and the efficiency of aquaculture in tidal flat ponds is low, and the survival rate of japonicus japonicus is not high, which is greatly affected by the external environment.

Moreover, sea cucumbers have high requirements on the substrate environment, especially in summer, the bottom of the pool is prone to hypoxia, and harmful substances such as hydrogen sulfide produced at the bottom cause a large number of sea cucumbers to die.
