Embodiment
Below in conjunction with accompanying drawing 1 ~ accompanying drawing, 5 couples of the present invention are described below.
As shown in Fig. 1 ~ 5, the present invention includes 1, culturing area selects
According to the situation at the bottom of the degree of depth of seashore seawater and beach, select slow seashore phytal zone, water region as culturing area.
2, breeding cage is set
The sea water advanced position selecting the ebb tide water surface and cage mouth to maintain an equal level arranges breeding cage.
The structure of breeding cage: shown in Fig. 1-5, make down as cylindrical shape with steel pipe by being interconnected, the upper cage 1 for platform taper, at the peripheral wrapped multiple net of cage as bag net 2, the network interface 2.1 of the pocket-like that can tighten up is left in the upper end suitable for reading of bag net, cage bottom is connected with metal spacer screen 3, to net in the cage inner chamber that forms with bag at cage and be provided with polygonal artificial reef 4, there is in it artificial reef hole 4.1, in artificial reef, staggered attachment is fixed with decortication box 5, the side of decortication box is provided with import 5.1, bottom is provided with sand bed 5.2, the top of cage is provided with cage mouth 6, protecting against shock cover 7 is enclosed with in the outside of the bottom of cage bag net.
The selection of mesh, according to kind and the size of cultivated crab, select the fishing net being less than the eyelet of crab volume 1/3rd as bag net, bag net can arrange one deck to multilayer.
3, bait is thrown in
After being opened by network interface 2.1, in cage, throw in fish and shrimp diet, eat for crab.Every day throws in once.
4, bait natural propagation with search for food
For fishes and shrimps, crab excreta has trophism and edibility.So meeting self-sow algae inside and outside artificial reef, algae can grow after absorbing crab excreta fast, and for small fish and shrimp and aquatile provide food, simultaneously set in artificial reef hole protects place for it provides, and forms small ecotope.Meanwhile, after small fish and shrimp and biology are grown up, the living bait of crab can be become.
5, gather in the crops, can gather in the crops at any time when crab grows up to when can eat, during results, sling by cage, people enters in cage, carries out collecting finished product crab, for merchandise sales.
Artificial reef can be arranged on cage inner bottom part, also can be layered in centre in cage, and box of peeling is attached in artificial reef.
Embodiment
Culturing area is selected
Select the seashore reaching cage mouth position during seawater ebb tide to delay aqua region as culturing area, seawater has biocenose in great numbers.
2, breeding cage is set
With diameter 10 meters, the size of height 4 meters carries out the construction of breeding cage.Using perigone crab as breed variety.Cage adopts the steel-pipe welding of diameter 1.2 inches to form, it is 2 centimetres in the aperture, bottom of cage, diameter is the spacer screen of the steel wire establishment of 0.6 centimetre, the structure of breeding cage is as shown in the figure: at cage 1 periphery parcel 2 layers of eye diameter at the fishing net of 0.5 centimetre as bag net, the network interface of the pocket-like that can tighten up is left in the upper end suitable for reading of bag net, its pocket prolongs 1 meter, the bottom of netting the cage inner chamber formed at cage and bag is provided with polygonal artificial reef, has artificial reef hole in it.Artificial reef is made up of cement concrete, and diameter is at 10 cm.Staggered attachment fixed part decortication box in artificial reef.Decortication box is rectangle, and its height is at 10 cm, and thickness is at 10 cm, and inlet height, at 5 cm, is provided with sand bed in the bottom of decortication box, with particle diameter at the sea sand of 1-3 centimetre as sand bed.Sew up as protecting against shock cover with mackintosh at the bag net lower outside of breeding cage.
3, bait is thrown in
Throw in a fish and shrimp diet every day, bait used is freezing small-sized fishes and shrimps kind.
4, bait natural propagation with search for food
Natural propagation and growth under the micro-ecological environment that fishes and shrimps living bait is formed in artificial reef, eat as living bait for crab after growing up.
5, gather in the crops
During results, sling by cage, people enters in cage and collects crab.
Advantage of the present invention:
1, achieve mariculture to raise in cages and grow crab, solve the technical problem of crab artificial feeding;
2, at the peripheral wrapped multiple fishing net of cage, prevent the generation of crab escape phenomenon in breeding process, also avoid crab natural enemy to encroach on crab simultaneously, or harass normal growth and the growth of crab;
3, can throw in bait by it when the network interface set by cage mouth top is opened, bait is tightened after throwing in, and prevents crab from escaping;
4, the artificial reef arranged at the bottom of cage can create micro-ecological environment, be conducive to external fishes and shrimps within it breed and grow, make use of excreta and the bait residue of crab simultaneously, keep the clean of water body and health, the fishes and shrimps grown eat for crab as living bait, are conducive to growth and the growth of crab;
5, crab is constantly peeled in necessary for growth, and the crab housing of decortication is soft, is easily gnawed by the crab of not peeling, causes the death of crab.Owing to being placed with decortication box in breeding cage, when crab will be peeled, just can pierce in decortication box by import, and then pierce in sand bed, peeled, after growing new skin after decortication by the frictional force of sand bed and environment, just can get out from decortication box, continue Bian food and grow;
6, because crab is by the living bait manually providing bait and breed in cage of naturally searching for food in growth and development process in breeding cage, so, can not cause and be short of food, also the needs that crab normal growth is grown are ensured, so fast growth, reaches commercial specification fast, and, can gather in the crops at any time.There is saving bait, the plurality of advantages improving growth rate and gather in the crops at any time.
7, the Population breeding of crab is conducive to.After crab reaches sexual maturing period in cage, a large amount of fertilized eggs will be produced, along with the flowing of seawater, be diffused in other region of seawater, for the population expansion of crab provides provenance condition, so be conducive to the improvement of natural, ecological and the recovery of marine organisms population.
