Abstract
A kind of raft-type net bed shellfish breeding method, with the net sheet doubling of tailoring, sew up base and top margin, some separate layers are made in parallel kneading between base and top margin, from side respectively to each separate layer row shellfish seedling of evenly packing into, sew up side, the top margin both sides are installed lifting rope respectively, and the both sides, base are installed dropstone respectively, hang on the frame rope through lifting rope then, a shellfish seedling i.e. word is evenly arranged on each separate layer, is clamped in naturally in the net sheet.The present invention makes the shellfish seedling relatively independent, and survival rate can reach more than 98%, and output can improve more than 30%, can reduce cost more than 80%, be applicable to various shellfish raft formulas and broadcast breed.
Description
The present invention relates to the shellfish culture method, more particularly is a kind of improved cultural method to shellfish raft formula cylinder mould cultural method and shellfish raft formula shackle culture method.
As everyone knows, existing shellfish raft culture method has cylinder mould cultural method and shackle culture method.Raft formula cylinder mould cultural method is that the net sheet surrounds circular cylinder mould, the cylinder mould inner stacks is provided with some separate layers, separate layer is that circular separator disc is made on the net sheet, at the joint mouth place of cylinder mould one side perpendicular to separator disc, irregular freely the mixing of shellfish seedling is placed on the separator disc, sews up the joint mouth of cylinder mould then, center, cylinder mould top is provided with a lifting rope and hangs on the frame rope, its center, below is provided with single dropstone, to stablize cylinder mould.This cultural method, because of the cylinder mould volume is big, investment is big, and the people is unfavorable for that for causing the current barrier water flowing is through-flow, makes shellfish picked-up bait few, and the influence growth increases lethality, and volume is difficult to operation greatly, scrubs difficulty; Shellfish is unfixing on separator disc, particularly to the underdeveloped shellfish of byssus, as: stalwart blood clam, Patinopecten yessoensis, bay scallop etc., because the fluctuation of current, unstable on separator disc, run foul of each other, cause damage, normally initial feeding influences growth, increases lethality.For firm shellfish, prevent mutual collision, occurred at installing flexible article such as old twine between the shellfish in recent years and strengthened dropstone below the cylinder mould, this has just increased cost, has increased barrier, and it is through-flow to have had a strong impact on water flowing, the picked-up and the growth of bait have been influenced, increased lethality, simultaneously, owing to increased filler and dropstone weight, operate and scrub difficulty more, also increase the load of lifting rope and frame rope, made the lifting rope fracture easily, be unfavorable for safety in production.Raft formula shackle culture method is to bore a hole on the big ear of scallop, and it is a string to adopt cotton rope to wear into, vertically hangs on the frame rope, its below is provided with dropstone, is stablized this cultural method, though solved the problem of current barriers, need on the big ear of scallop, bore a hole, time-consuming, when operating and scrubbing, very easily make cracked the coming off of perforation, one meets stormy waves also easily makes cracked the coming off of perforation, is unfavorable for safety in production, therefore, be not suitable for large-area applications.
The objective of the invention is to overcome above-mentioned shortcoming, provide between a kind of shellfish and can not collide mutually, current are unimpeded, are convenient to absorb bait, help the growth, operate and scrub easy, production safety, raft-type net bed shellfish breeding method with low cost.
For achieving the above object, feature of the present invention is: the net sheet doubling that will tailor, sew up base and top margin, some separate layers are made in parallel kneading between base and top margin, from side respectively to each separate layer row shellfish seedling of evenly packing into, sew up side, the top margin both sides are installed lifting rope respectively, and the both sides, base are installed dropstone respectively, hang on the frame rope through lifting rope then, a shellfish seedling i.e. word is evenly arranged on each separate layer, is clamped in naturally in the net sheet.
The present invention can make the shellfish seedling independent separately, is clamped in naturally in the net sheet, has overcome between the shellfish and has collided mutually, rubs, and the shortcoming that current are not smooth is convenient to absorb bait, helps growth, and survival rate can reach more than 98%, and output can improve more than 30%; Simultaneously, operate and scrub easy, labour intensity is low, and production safety is with low cost, can reduce cost more than 80%.Be applicable to various shellfish raft culture, broadcast breed with also being applicable to various shellfishes.
Description of drawings
Accompanying drawing is a schematic diagram of the present invention, also is the schematic diagram of a kind of embodiment.
Fig. 1 is a front view, and Fig. 2 is the left view of Fig. 1.
Provide embodiment below in conjunction with accompanying drawing.
Embodiment: as shown in the figure,, sew up base and top margin with net sheet 2 doublings of tailoring, some separate layers 1 are made in parallel kneading between base and top margin, make several layers net bed, respectively to each separate layer 1 row's shellfish seedling of evenly packing into, sew up side from side, the top margin both sides are installed lifting rope 3 respectively, the both sides, base are installed dropstone 5 respectively, hang on the frame rope through lifting rope 3 then, and a shellfish seedling i.e. word is evenly arranged on each separate layer 1, independent separately, be clamped in naturally in the net sheet 2.Adopt two lifting ropes 3 and two dropstone 5 can prevent disorderly pendulum of net sheet 2, can only be as the directional swing of playing on the swing.For the ease of operating, protecting and scrub, can be provided with framework 4 on the net sheet 2, with supporting network sheet 2, framework 4 can be made on net sheet 2, and net sheet 2 is hung behind the frame rope, according to the variation and the typhoon phase of season and water temperature, the length of timely adjustment lifting rope 3, scrub through checking to protect with irregular, until forming, this is that prior art no longer describes in detail.The sowing time end, as long as the frame rope is become the bottom line rope sinks to the seabed, during results, can all pack up as long as mention the bottom line rope, can prevent harmful animal effectively, results are convenient.
Claims (2)
1, a kind of raft-type net bed shellfish breeding method, it is characterized in that: the net sheet doubling that will tailor, sew up base and top margin, some separate layers are made in parallel kneading between base and top margin, from side respectively to each separate layer row shellfish seedling of evenly packing into, sew up side, the top margin both sides are installed lifting rope respectively, and the both sides, base are installed dropstone respectively, hang on the frame rope through lifting rope then, a shellfish seedling i.e. word is evenly arranged on each separate layer, is clamped in naturally in the net sheet.
2, raft-type net bed shellfish breeding method according to claim 1 is characterized in that: said net sheet is provided with framework.
