Abstract
The present invention discloses a catching method suitable for aquatic products particularly commercial fishes cultured in large water areas. Fishing nets used by the method include a drawing net, a vertical net and a net cage, wherein the net depth of the drawing net is roughly equal to water depth, and the net width is consistent with water surface width; a diver pulls a foot line of the drawing net and dives from one end of a lake or one end of a reservoir to the other end of the lake or the reservoir along the ground; and along with diver's dive, one net cage is hung on the back of the drawing net, a small opening is kept to enable a shoal to enter the net cage, and thus, the fish can be caught when the fish enter the net cage. The method has the characteristics of less influence by water forms and landforms, convenient operation, fewer fishing nets, low cost and high catching rate.
Description
The present invention relates to the catching method of a kind of fresh-water fishes, belong to aquatic products and fish for technical field.
Nearly 2,800 hundred million mu of the existing at present waters of China, but only 7,500 ten thousand mu of surface dependencies.Cultured area such as lake, reservoir accounts for can support 72% of area, but its aquatic products amount only accounts for 27% of gross yield.One of reason is that the technology of fishing for is not caught up with.Release from Zhejiang aquatic products research institute in 1964 catch up with, behind the hurdle, thorn, Zhang Lianhe fishing method, the backwards situation of fresh water fishing is change to some extent.So-calledly catch up with, hurdle, thorn, Zhang Lianhe fishing method be meant to be provided with and catch up with net, hurdle net, gill net and fixation to throw the net that integration of operation is fished in lake, reservoir.With the hurdle net lake, reservoir are divided into several waters, in the waters of separating, are provided with and catch up with net, gill net, be used to drive the shoal of fish and divide fish pass, the shoal of fish is concentrated on the water section that has been easy to net operation, fixation is set herein throws the net, catch fish.Above-mentioned large-scale netting gear generally all is spliced by ready-made net sheet.Fish for this kind method, the water-expellling rate lake is 70%, and reservoir is 40-60%.Weak point is that the demersal fishes water-expellling rate is low, netting gear is provided with morely, and cost is higher.And other are sporadicly fished for, and output is littler.Because the fresh water fishing problem does not fundamentally solve, thereby become a great problem of puzzlement fish production.
The object of the present invention is to provide a kind of use netting gear less, and the fresh water fishing method that can catch demersal fishes, thereby aquatic products power improved significantly.
Catching method of the present invention is to be provided with one and to throw the net and dark equate, net wide with the depth of water and fish for the corresponding to drawn net of water surface width fishing for the waters, perpendicular net is connected with the headline of drawn net, being positioned at the top of drawn net, highly is 3-5 rice, and width is consistent with the width of drawn net.Draw the infraclass of drawn net during fishing operation piecemeal by the diver, from the lake, an end of reservoir moves under water to the other end along the bottom.Perpendicular net is used for preventing the jump escape of epipelagic fish.Along with moving under water of diver, drawn net just walks to the other end from an end of water body, and fish just concentrate on the place ahead of drawn net like this.When the shoal of fish reaches certain density, can push up net and struggle, drawn net will bear very big tension force.For preventing the shoal of fish escape of scoring a goal, behind drawn net, hang with 3-5 net cage, decontrol an osculum and make the shoal of fish enter net cage.Can accomplish like this with catching up with catching.For preventing to excessively capture, destroy fishery resources, should select the bigger drawn net of mesh for use, guarantee the commercial specification fished, accomplish to catch stay greatly little.When water-bed landforms were irregular, the diver can when the traction infraclass, walk around barriers such as house, trees according to actual conditions.
Effect of the present invention is very remarkable.It has solved pond for a long time, problem that reservoir fresh water fishing water rate is low, and a few peoples' operation just can fulfil assignment.It has following characteristics:
1, is not subjected to the influence of water shape, landforms.Drawn net can carry out operation according to the degree of depth and the width in different waters, and no matter how complicated water shape, landforms situation be, can both suit measures to local conditions to deal carefully with.
2, use netting gear simple.Omit hurdle net, gill net, reduced cost.
3, catches are fresh, the commodity rate height.The fish that catch can go on the market at any time, but also quick refrigeration storage.
4, water-expellling rate height.Not only can catch pelagic fishes, also can fish for demersal fishes, water-expellling rate can reach more than 95%.
Embodiment:
The inventor once fished with this method in many places, and major part all is one man operation under water, and catch is all very high.Following table is the statistical form that the inventor uses this method to fish in the part waters:
| The place | Area (mu) | Quantity of the catch (ten thousand jin) | Activity duration |
| Clear first Dunhua Mudanjiang | 70 10 300 | 4 1 6 | 3 hours 1.5 hours 4 days |
When the operation of Mudanjiang, do not have enough quick freezing units and net cage, therefore have to the fish that has caught is put back in the water again because of reservoir.
Claims (1)
1, a kind of fishing method, it is characterized in that: the one dark wide and corresponding to drawn net of water surface width that equates, nets with the depth of water of throwing the net is set fishing for the waters, erects net and be connected, be positioned at the top of drawn net with the headline of drawn net, highly be 3-5 rice, width is consistent with the width of drawn net; Drawn the infraclass of drawn net during fishing operation piecemeal by the diver, from the lake, an end of reservoir moves under water to the other end along the bottom, along with moving under water of diver, drawn net just walks to the other end from an end of water body; Behind drawn net, hang with 3-5 net cage, when school density is big, on drawn net, decontrols an osculum shoal of fish is entered in the net cage, can accomplish like this with catching up with catching.
