Description
Technical field
The present invention relates to the breed of scallop, especially a kind of cultivator of Patinopecten yessoensis.
Background technology
Patinopecten yessoensis (Patinopecten yessoensis) is under the jurisdiction of Mollusca, lamellibranchiata, Pectenidae, Patinopecten yessoensis genus, and advantages such as growth is fast, individual greatly, delicious flavour, nutritive value height that it has are a kind of important economic shellfishes.Patinopecten yessoensis is a kind of low temperature properties kind, originates in Japan and Russian coastal.Introduce China the eighties, beginning in Liaoning in Huanghai Sea the north, northern coastal breed such as Hebei, Shandong, become one of main shellfish culture kind very soon.
At present, the breed of Patinopecten yessoensis mainly contains bottom sowing culture and marine floating raft type hangs foster.
Bottom sowing culture, be to select sand mud substrate fishing ground, remove harmful organisms, by broadcasting seedling density is 8-10 piece/square metre, broadcasts the seedling time to be late November to the early December or the 3-4 month in next year then, and culturing time is 17 months, though being a kind of technology, bottom sowing culture simply, do not need material equipment, a kind of mode that cost is low, but its be subjected to the fishing ground substrate influence big, growth is slow, lethality is high, especially has harmful organisms such as starfish in the seabed more for a long time, exists the low deficiency of the rate of recapture.
Marine floating raft type hangs foster, is that spat is contained in the suitable container by certain density, is hung on to be provided with on the afloat buoyant raft (well rope) by certain distance and suitable water layer and forms.At any time can adjust because of the length of its lifting rope, the best water layer that scallop is always cultured is higher in bait concentration, temperature is suitable, thereby growth rate is very fast, and be convenient to production management and results.Marine floating raft type hangs foster mode and mainly contains three kinds: the one, and shackle culture: be with long spat to certain shell height (general more than 3 centimetres), bore an aperture with little drill bit at its vestibule base portion, wear bunchiness with polyethylene rope or nylon wire by 2 centimetres of spacings, every string 5-10, tie up on the thick rope by 6 centimetres of intervals then, hang and support on buoyant raft.Though this method cost is low, operation is taken a lot of work, and is also broken off with the fingers and thumb disconnected vestibule in the bigger sea area of stormy waves easily or twists into two parts the ear rope, easily causes damage.The 2nd, the pocket net is cultured: be the polythene net garment piece with a little mesh, be seamed into pocket shape seedling bag, spat is put into pocket (a bag), seal sack with line again and then it is hung on buoyant raft.This method capacity of anti-storm is strong, and survival rate height, but cost is higher is operated more numerously, and the easy assorted algae of attached assorted shellfish influences the exchange of breeding water body again.The 3rd, the lantern cylinder mould is cultured: the lantern cylinder mould is the most generally to adopt during present Patinopecten yessoensis is cultured, its structure is with the fixing etting of going up of the periphery of 6-7 plastic disc with holes, each plastic disc keeps at a certain distance away successively, thereby form the breed utensil of one " lantern " shape, this lantern breed cylinder mould capacity of anti-storm is strong, and current are unobstructed, and the scallop growth is fast, operate more conveniently, but one-time investment is big; What in addition, Patinopecten yessoensis was different with other kind scallops is: it secretes byssus in juvenile stage, anchors on the adherance; Along with growing up, the byssus of Patinopecten yessoensis comes off, and loses the set ability.When the lantern cylinder mould was subjected to the stormy waves water impact, the scallop in the cage is collision mutually, not only causes making the new first portion in edge of scallop shell to sustain damage, influence its outward appearance and market value, also can cause interlock mutually between the scallop, thereby make the soft tissue damage, cause mortality.Find in the practice, adopt the lantern cylinder mould to culture Patinopecten yessoensis, at sea culture the process of results from beginning, survival rate is about 30% only, has had a strong impact on the economic benefit of culturing.For fear of the death of Patinopecten yessoensis in forming process, mainly regularly fall cage at present (Patinopecten yessoensis about the long 5cm of shell only can be cultured 4 for every layer to reduce scallop culture density by growing up along with scallop.) method realize, not only increased culturing the requirement and the workload of cylinder mould, cause aquaculture cost to improve, even more serious is that fall cage operation causes scallop dried dew in air, can cause scallop and coerce, and reduces its growth rate even causes death.
Summary of the invention
For overcome in the prior art Patinopecten yessoensis shackle culture not wind wave resistance easily cause damage, pocket net aquaculture cost is higher, operate more numerous, easily adhere to the assorted algae of assorted shellfish and influence the exchange of water body, lantern cylinder mould breed survival rate is low, the cage that falls reduces cultivation density and causes the demand increase of workload and breed equipment and the cage that falls can cause the deficiency of negative effect to scallop, the invention provides a kind of cultivator of Patinopecten yessoensis, the cultivator of this Patinopecten yessoensis is not only simple in structure, cost is low, make easy, and water body smoothness, Patinopecten yessoensis survival rate height, the culture benefit height, labor strength is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cultivator of Patinopecten yessoensis, comprise first etting, it is characterized in that: also comprise some second ettings and a framework, described first etting is tightened, entirely is fixed in the described framework, described second etting is made respectively on the clothing body that is fixed on first etting, and constituting several mesh bags of space successively with first etting, a side of described mesh bag is provided with openable sack.
The described framework of tightening, entirely fix first etting is square.
The described framework of tightening, entirely fixing first etting is fixedly connected with reinforcement between its support body.
Make on the clothing body that is fixed on first etting and with first etting and constitute several second ettings of the mesh bag of space successively for described some, it is the corresponding respectively clothing body both sides that are fixed on first etting of making.
Described some second ettings are made on the clothing body that is fixed on first etting and with first etting and are constituted several mesh bags of space successively, and its openable sack is arranged on the mesh bag upside.
