Background technology
Current, the Apostichopus japonicus Aquaculture development is swift and violent.2010, the apostichopus japonicus culture area of China and output only account for ten thousand hectares of the 7.21%(15.01 of national sea water breeding area) and ten thousand tons of the 0.88%(13.03 of output), its output value but reaches hundred million yuan of the 15.79%(260 of the national mariculture output value), stichopus japonicus has become the species of single output value maximum in China's mariculture industry.Wherein, bottom sowing culture is due to the natural environment that can simulate stichopus japonicus existence, growth, and the excellent product quality of production is subject to consumer's favor.The stichopus japonicus bottom sowing culture extensively adopts the artificial materials such as stone, tile, plastic tube, cement components as adherance, the restriction that is subjected to local resources environment, natural environment, social environment of these materials, need to drop into a large amount of production costs, restricted construction speed and the implementation result of stichopus japonicus aquaculture reefs; Use on the other hand artificial material as the adherance of stichopus japonicus, the surface area of formation is few, and other bait growth rate such as algae are slow, can not provide sufficient bait for sea cucumber.
Summary of the invention
The object of the present invention is to provide a kind of ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture, when solving artificial material and being used for the stichopus japonicus bottom sowing culture as adherance, exist surface area few, can not provide the sufficient problems such as bait for sea cucumber.
The objective of the invention is to be achieved through the following technical solutions:
A kind of ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture, the scallop shell that will adhere to the spat of oyster drop into stichopus japonicus bottom sowing culture marine site, form the scallop shellfish bed of thickness 10-20cm in the seabed; Along with self-sow and the breeding of the spat of oyster on scallop shell, in advance scallop shellfish bed is played solidification; Through the time more than 2 years, form the live body oyster bioherm on original scallop shellfish bed; Broadcast juvenile stichopus by the diver to live body oyster bioherm upper base, realize the ecological aquaculture of stichopus japonicus.
The described ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture, the scallop shell that adheres to the spat of oyster adheres to the scallop shell of the spat of oyster or scallop shell is put to the scallop shell of the natural waters nature good attachment spat of oyster after gathering in the crops scallop.
The described ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture is broadcast juvenile stichopus more than the 5g/ head by the diver to live body oyster bioherm upper base, realizes the ecological aquaculture of stichopus japonicus.
The described ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture, the scope of broadcasting juvenile stichopus to live body oyster bioherm upper base by the diver is the 5-100g/ head.
The described ecological shell reef preparation method that is applicable to the stichopus japonicus bottom sowing culture, the time range that forms the live body oyster bioherm on original scallop shellfish bed is 1-4.
Advantage of the present invention and beneficial effect are:
1. the present invention takes full advantage of the advantage of cultured scallop, and the scallop shell of the natural spat of oyster that will adhere to is put into the seabed and built the live body oyster bioherm, can turn waste into wealth, and realizes the comprehensive utilization of resource;
2. in the present invention, oyster can purify seabed water quality in process of growth, adhering to and growing good environment is provided for stichopus japonicus;
3. in the present invention, scallop, oyster shell have the abundant space of adhering to, and are convenient to adhering to of benthic diatom, for stichopus japonicus provides the high-quality natural bait;
4. the present invention fully simulates the living environment of stichopus japonicus, has improved the quality of precious marine product;
5. the present invention is easy and simple to handle, reduces labor intensity, and is convenient to management and results;
6. the present invention weakens cultivation to the impact of natural waters ecotope, is conducive to cultivate reparation and the comprehensive utilization of marine ecosystem environment.
Embodiment
Embodiment 1
In the present embodiment, Laizhou Wan is gathered in the crops scallop shell that scallop adheres to the spat of oyster winter drop near stichopus japonicus bottom sowing culture marine site Laizhou Wan soil mountain, form the scallop shellfish bed of thickness 10cm in the seabed.Along with self-sow and the breeding of the spat of oyster on scallop shell, in advance scallop shellfish bed is played solidification; Through the time of 1 year half, form the live body oyster bioherm on original scallop shellfish bed; Broadcast the juvenile stichopus of 10-17g/ head by the diver to live body oyster bioherm upper base, realize the ecological aquaculture of stichopus japonicus.
Embodiment 2
In the present embodiment, Laizhou Wan is gathered in the crops scallop shell that scallop adheres to the spat of oyster winter drop near stichopus japonicus bottom sowing culture marine site Laizhou Wan lotus island, form the scallop shellfish bed of thickness 15cm in the seabed.Along with self-sow and the breeding of the spat of oyster on scallop shell, in advance scallop shellfish bed is played solidification; Through the time of 4 years, form the live body oyster bioherm on original scallop shellfish bed; Broadcast the juvenile stichopus of 15-20g/ head by the diver to live body oyster bioherm upper base, realize the ecological aquaculture of stichopus japonicus.
Embodiment 3
In the present embodiment, Laizhou Wan is gathered in the crops scallop shell that scallop adheres to the spat of oyster winter drop near stichopus japonicus bottom sowing culture marine site Laizhou Wan Zhu Wang port, form the scallop shellfish bed of thickness 20cm in the seabed.Along with self-sow and the breeding of the spat of oyster on scallop shell, in advance scallop shellfish bed is played solidification; Through the time of 2 years half, form the live body oyster bioherm on original scallop shellfish bed; Broadcast the juvenile stichopus of 5-10g/ head by the diver to live body oyster bioherm upper base, realize the ecological aquaculture of stichopus japonicus.
The embodiment result shows, the present invention can purify seabed water quality, adhering to and growing good environment is provided for stichopus japonicus; Improve the quality of stichopus japonicus product, be conducive to realize the comprehensive utilization in habitat rehabilitation and sea area.
