Problems solved by technology

Due to serious sediment pollution, seawater fish cage culture areas are not suitable for sea cucumber bottom-sowing culture. Although sea cucumbers can be separated from the heavily polluted seabed sedimentary environment by directly culturing inside the cages, due to the relatively large mesh size of ordinary cages Large, not

Embodiment 1

[0020] Embodiment 1: Cultivation of imitation sea cucumber

[0021] The water temperature in the southern sea area is low in autumn and winter, and the environmental conditions are very suitable for the growth of sea cucumbers in the north. From December 2009 to March 2010, the cage culture research of fish and japonicus japonicus was carried out in Dapeng'ao waters of Daya Bay using this breeding facility. The cage body used is made of polyethylene mesh with a mesh size of 0.6cm, with an area of ​​about 10m 2 , add a certain amount of PVC corrugated board assembly inside as a sea cucumber shelter; the cultured fish are grouper and other bream fish, and the daily feeding is mainly chilled miscellaneous fish, etc., supplemented by bait; the imitation japonicus used Purchased from Yantai, Shandong Province, the average wet weight is about 70g, and 5kg of sea cucumbers are placed in a single cage, which is about 0.5kg / m 2 ;During the breeding period, the water temperature is lo...

Embodiment 2

[0022] Embodiment Two: Yuzu Sea Cucumber Cultivation

[0023] After harvesting the imitation japonicus, from the end of May 2010, the cultivation facility was used to cultivate the local species of sea cucumber Yuzu sea cucumber in Daya Bay. Dissolved oxygen 6.5mg / L. During the experiment, the cultured sea cucumbers were bright in color and had good activity, and a large amount of sea cucumber feces could be observed at the bottom of the cages, indicating that this species of sea cucumbers could well feed and utilize the sediments in the cages.

[0024] The results of the examples show that the facility is easy to manufacture and can provide sufficient and suitable habitat space for sea cucumbers in the cage area; the breeding facilities can be adapted to time and local conditions to breed different types of sea cucumbers, and are convenient for production management. Applying this facility to fish and sea cucumber polyculture can effectively improve the ecological efficiency...

Abstract

The invention relates to a culture facility for the mixed culture of fishes and sea cucumbers and use method thereof, in particular a structural improvement on the current cages for the mixed culture of fishes and sea cucumbers. The culture facility comprises an anchor rope, a case body, a floater, a cover net, a shield and a sinker. The use method is characterized by using a compact net to manufacture a net case body, adding the shield into the net case to increase three-dimensional space of the system and provide habitat for the sea cucumbers, wherein off-bottom culture of the sea cucumbers can be realized by using the facility, and deposits generated during fish culture can be effectively utilized. The facility has a simple structure and a convenient manufacture process, and is capable of culturing sea fishes while polyculturing the sea cucumbers with higher economic value; therefore, the facility expands the current breeding space, effectively reduces the environment pollution problem caused by culturing sea fishes and increases the economic returns of the system.

Description

technical field [0001] The invention relates to a breeding facility for seawater fish and sea cucumber polyculture, in particular to an improved net cage for seawater fish. Background technique [0002] During the cage culture of marine fish, a large amount of culture waste such as residual bait and feces will be produced, and the discharge of these wastes into the water body will cause huge pollution to the environment. Studies have shown that sediment-eating sea cucumbers can effectively use the waste produced in the fish cage culture process and achieve their own rapid growth. The polyculture of sea cucumbers in cages can bring additional economic value and clean the culture environment . Due to serious sediment pollution, seawater fish cage culture areas are not suitable for sea cucumber bottom-sowing culture. Although sea cucumbers can be separated from the heavily polluted seabed sedimentary environment by directly culturing inside the cages, due to the relatively lar...
