Abstract
The invention discloses a kind of catching method that is applicable to big water surface aquaculture product, particularly economic fish.Use the used netting gear of this method to comprise drawn net, perpendicular net and net cage, dark and the depth of water of drawn net net about equally, net wide consistent with water surface width, the diver draws the infraclass of drawn net, from the lake, an end of reservoir moves under water to the other end along the bottom, along with moving under water of diver, hangs a net cage behind drawn net, decontrol an osculum shoal of fish is entered in the net cage, can accomplish like this with catching up with catching.It has following characteristics: be not subjected to the influence of water shape, landforms, use netting gear few, easy and simple to handle, cost is low, the water-expellling rate height.
Description
What the present invention relates to is the particularly catching methods of economic fish of the big water surface aquatic products of culturing, and belongs to aquatic products and fishes for technical field.
Nearly 2,800 hundred million mu of the existing at present waters of China, but and only 7,500 ten thousand mu of surface dependencies.Big water surface 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 that the big water surface is caught up with, behind the hurdle, thorn, Zhang Lianhe fishing method, just changed the backwardness that the big water surface is fished for gradually from Zhejiang aquatic products research institute in 1964.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 fish are fished in integration of operation 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 is easy to the hauling damage, fixation is set herein throws the net, catch fish.Fish for associating fishing method, the water-expellling rate lake is generally 70%, and reservoir is 40-60%.Weak point is that the demersal fishes water-expellling rate is not high, and netting gear is provided with more, and cost is higher.And other are sporadicly fished for, and output is littler.Because the problem of fishing for does not solve, therefore also just be far from being and improved aquatic products power with this means.
The object of the present invention is to provide a kind of use netting gear less, and can catch the big water surface catching method of demersal fishes, thereby improve aquatic products power significantly.
The present invention uses instruments such as ship, netting gear to carry out fishing operation.Used netting gear comprises a drawn net, a perpendicular net and 3-5 net cage.Dark and the depth of water of drawn net net is netted wide consistent with water surface width about equally.Perpendicular net is connected with the headline of drawn net, is positioned at the top of drawn net.The height of perpendicular net is a 3-5 rice, and width is consistent with the width of drawn net.Draw the infraclass of drawn net during fishing operation 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 fish such as flower silver carp, carp.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.At this moment for preventing the shoal of fish escape of scoring a goal, behind drawn net, hang with net cage, decontrol an osculum shoal of fish is entered in the net cage.Can accomplish like this fish " can be caught all in one draft " with catching up with catching.For preventing to excessively capture, destroy living resources, should select the bigger drawn net of mesh for use, guarantee that the fishing gear of being caught has commercial specification.If will select the fingerling of different size for use, can use respective wire purpose drawn net.Can accomplish like this to catch stay greatly little.When water-bed landforms were irregular, the diver can be according to actual conditions, and the traction infraclass is walked around barriers such as house, trees.
Effect of the present invention is very remarkable.It has solved the big for a long time water surface and has fished for the low problem of water rate, and one or two people damage just can fulfil assignment, and almost can accomplish " catching all in one draft ".It has following characteristics:
1, is not subjected to the influence of water shape, landforms.Drawn net can be selected the suitable degree of depth and width according to 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 few, easy and simple to handle, cost is low.It has omitted and has caught up with net and gill net to simplify operation sequence, thereby has saved the time, has 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, 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 former Dunhua Mudanjiang | 70 10 300 | 4 1 6 | 3 hours 1.5 hours 4 days |
When the operation of Mudanjiang,, therefore have to the fish that has caught is put back in the water again because of reservoir does not have quick freezing unit and enough net cages.
Claims (1)
1, a kind ofly be applicable to big water surface aquaculture product, the catching method of economic fish particularly, use ship, the netting gear instrument carries out fishing operation, it is characterized in that: use the used netting gear of this method to comprise a drawn net, a perpendicular net and 3-5 net cage, dark and the depth of water of drawn net net about equally, net wide consistent with water surface width, perpendicular net is connected with the headline of drawn net, be positioned at the top of drawn net, the height of perpendicular net is a 3-5 rice, and width is consistent with the width of drawn net, draw the infraclass of drawn net during fishing operation by the diver, from the lake, one end of reservoir moves under water to the other end along the bottom, and 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 net cage, when school density is big, on drawn net, decontrol an osculum shoal of fish is entered in the net cage, can accomplish like this with catching up with catching.
