Abstract

The utility model relates to a raft frame with pectinated bores for culturing scallop, and the utility model comprises a buoy 1 and a floating rope 4. Both ends of the floating rope 4 are provided with peg cables 6, and the ends of the peg cables 6 are provided with pegs 9. The lower end of the floating rope 4 is provided with a scallop net cage 7 through a net cage tie 5. The utility model is characterized in that the upper end of the floating rope 4 is provided with the buoy 1 through a line extension buoys hanging tie 3. Only the line extension buoys hanging tie (3) of the utility model is improved, and therefore, the culturing method of scallop in the pectinated bores has a breakthrough development, and the culturing purpose of the line extension for buoys hanging and sinking raft frame is achieved. The scallops can quickly grow in the water area with a length of 6-14 m and have high survival rate and the best growth, and the attack of storm tide can be efficiently avoided. Compared with conventional culturing, the survival rate of the scallops cultured by the utility model increases by 8-10%, and the production of the scallops cultured by the utility model increases by 22-24%.

Description

A kind of chlamys farreri culture raft frame

The chlamys farreri culture raft frame that the utility model relates to belongs to the aquatic products technology, is a kind of aquaculture tool specifically.

Cursory directly tying up on the floating well rope on the existing culture raft frame, the raft frame is in the water layer of 0.2-0.3m and at this water layer belongs to the district that surges, the range of instability that just belongs to seawater, resist tropical cyclone and storm ability, and in such waters, do cultured scallop, harmful animal is many, adheres to a large amount of oysters, mussel on the cylinder mould, can cause the scallop lethality up to 70%-80%.

The purpose of this utility model is intended to improve above-mentioned deficiency, provides a kind of and can resist that tropical cyclone and storm tide ability are strong, attachment is little on the cylinder mould, and the scallop lethality is low, the fast special use breed instrument that prolongs water boom of rope, sinking raft frame of grow.

In order to achieve the above object, the utility model is achieved in that it comprises cursory 1, a floating well rope 4, floating well rope 4 two ends are that short wooden stake cable 6 is arranged, there is short wooden stake 9 in short wooden stake cable 6 terminations systems, and floating well rope 4 lower ends are 5 to be that scallop cylinder mould 7 is arranged by cylinder mould, is characterized in that floating well rope 4 upper ends are 3 to be to have cursory 1 by prolonging water boom of rope.

In order to achieve the above object, prolonging water boom of rope is 3 long 6-14m.

In order to achieve the above object, prolonging water boom of rope is that 3 long 10-12m are best.

This culture raft frame ties up on the floating well rope cursory by prolonging water boom of rope system, has solved the breed purpose of prolonging water boom of rope, sinking raft frame well, makes the waters growth of scallop in 6-14m fast, the survival rate height, that grows is best, can avoid storm tide to attack effectively, and output can improve 22-80%.

Description of drawings:

Accompanying drawing is structural representation of the present utility model (also for the raft frame afloat structural representation being set).

The explanation of accompanying drawing drawing:

1 is cursory, 2 seawater planes, and 3 prolong water boom of rope system, 4 floating well ropes, 5 cylinder moulds system, 6 short wooden stake cables, 7 cylinder moulds, plane, 8 seabed, 9 short wooden stakes.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Floating well rope 4 can adopt Φ 22-24cm polyethylene rope, two short wooden stake cables 6 are tied up to floating well rope 4 two ends, make a call to a fast knot, there is short wooden stake 9 in short wooden stake cable 6 lower ends system, can at first in the middle of the art short wooden stake, bore a hole, short wooden stake cable-end head is passed by the hole, make a call to a fast knot at short wooden stake cable-end head and get final product, floating well rope upper end by one prolong water boom of rope be 3 tie up to cursory 1 above, prolong water boom of rope and be 3 length 6-14m, it is best getting 10-12m, cursory 1 can adopt the plastic hollow of Φ 28cm cursory, and cylinder mould 7 can adopt cylindrical scallop cylinder mould, and the scallop cylinder mould is that 5 desirable length are 1.5m, Φ is the polyethylene rope of 3mm, length of peg cable can determine to the degree of depth on plane, seabed 8 according to seawater plane 2, and the 2.5-3 that generally gets length of peg cable and be the depth of water doubly, short wooden stake 9 adopts the locust tree short wooden stake, and short wooden stake 9 is generally got 1.8-2m, short wooden stake places 3-4m place, seabed, beat the jail and fasten.

Arrived the cultured scallop time, on request the flow direction of raft frame according to culture zone water set, will divide good scallop seedling to put cylinder mould into by 60 every layer, a raft frame can be provided with 8 layers, and distance is 30-35m between platform and the platform, and distance is 150m between the Qu Yuqu.

Routinely culture raft frame and the utility model compare culture experiment, same branch seedling specification, Same marine site, same time cultivation, conventional culture raft frame is because being in the shallow marine site of water layer, and wind resistance is sudden and violent Ability, attachment is many, and survival rate is low, prolongs water boom of rope, sinking raft frame than the high 8-of conventional method survival rate 47%, output increased 22-80%, its main cause is to hang that to float be lengthening, and the raft frame is to downward-extension, and scallop is put Support the degree of depth at 10-12m, the one, anti-assorted shellfish, assorted algae apposition growth, cylinder mould is clean, the mesh good water permeability, Many by bait in the cylinder mould in the unit interval, scallop is ingested sufficient, so fan suction growth is fast, survives The rate height; The 2nd, the wind and wave resistance safety coefficient is strong, when scallop runs into storm tide, because cylinder mould is in apart from the billow wave In the pelagic environment below the wave impact power, scallop is in the stable environment and still can opens in the time of distinguished and admirable day The shell drainage is ingested, so growth is fast, and the survival rate height.
