Embodiment 1

[0035] A sea cucumber sea cage ecological seedling raising method:

[0036] Choose natural bays with small wind waves and flowing water, no strong currents, no pollution, and rich bait, and natural sea areas where the water depth can reach 6-7m or more during low tides as the seedling sea area.

[0037] (1) Making and placing seedling cages

[0038] The sea cucumber ecological seedling cage is fixed in the seedling sea area by a fixing device. The fixing device includes a fixing board 1, a float 2, a connecting device and an elastic buffer device 3. The fixing board 1 is a wooden board or other materials with a width of 20-30 cm and a thickness of 3-6 cm. The board, the connection device is a screw and a rope, the elastic buffer device 3 is a tire or a thick rubber belt, the float 2 is bound and fixed under the fixed board by a rope, and the fixed boards are connected by screws to form a 5m*5m square, forming a unit, 200 meshes The sieve silk net is fixed on the fixed plate 1...

Abstract

The invention relates to the technical field of aquaculture, in particular relates to young sea cucumber raising techniques, and specifically relates to an ecological method for raising young sea cucumbers in offshore net cages. The method comprises the following steps of: making and putting raising net cages, selecting seed sea cucumbers, performing fertilization and hatching, raising larvae, raising young sea cucumbers, raising offshore in the winter, and stripping young sea cucumbers. The method selects natural sea areas for green ecological raising of young sea cucumbers, does not need any chemicals or artificial baits, utilizes abundant bait resources in natural sea areas, is energy-saving and environment-friendly, and achieves the purpose of natural and ecological raising of young sea cucumbers. The offshore raising method effectively reduces the raising cost, saves land resources, and reduces consumption of electrical energy and other energy sources. Besides, by virtue of natural selection and offshore overwinter, the quality of young sea cucumbers is improved and the aquaculture survival rate is increased.

Description

[0001] Technical field [0002] The invention relates to the technical field of aquaculture, in particular to sea cucumber seedling raising technology, in particular to a method for sea cucumber ecological seedling raising in net cages on the sea. Background technique [0003] Since the mid-1990s, there has been a sea cucumber breeding boom in my country. For Dalian, which has a large scale of aquaculture, after nearly 10 years of development, the sea cucumber industry has been formed in the city. Analyzing the current situation and development trend of this industry is of great significance to the sustainable development of the national aquaculture industry. In recent years, with the continuous expansion of sea cucumber farming scale, problems in sea cucumber farming have gradually emerged. Before 2003, there were basically no diseases in sea cucumbers, and in 2004, sea cucumber diseases broke out. Judging from the forecasting and reporting of aquatic diseases in 2004, ...
