And a method of laying a grid array.
One design of the guide nets (barrier nets) is shown in figure 20, and the guide nets are designed into mesh sizes according to fishing specifications. In the drawing 20, a head line is arranged above, a plurality of circles on the head line represent a plurality of floats, a foot line is arranged below, a plurality of rectangles on the foot line represent a plurality of sinkers, head line connecting rings are arranged on two sides of the head line, foot line connecting rings are arranged on two sides of the foot line, and rope binding is convenient to install. The guide net can be made of polyethylene.
When the weight of the recaptured fish body is more than 3.5 kilograms, the mesh specification is 16 centimeters, the height of the guide net is designed according to the deepest water level of the lower net position of the reservoir, which can be equal to the water depth plus three meters, the total length of the guide net is designed according to the width of the reservoir and the size of the net array, and the buoyancy and the settlement force of the guide net are designed according to the stormy wave flow velocity of the reservoir.
For example: a large-scale grid array in front of a Guanyin pavilion reservoir dam is adopted in an internal test, the mesh specification is 16cm, the height of each guide net is 58 meters, more than six floats are provided, and more than twenty thousand floats are provided.
The fish is tested and caught in the white stone reservoir, and as a result, the fish has relatively complete variety, relatively high yield, good fish skin, high survival rate, more large fishes and basically no small fishes and juvenile fishes. The deepwater fishing large-scale net array is tested in five large reservoirs (a white stone reservoir, a kwan-yin pavilion reservoir, a clear river reservoir, a firewood river reservoir and a soup river reservoir) in the Liaoning province water source, and is removed after the test, and the test conditions are summarized as follows:
1. the fishing is stable and high in yield, the fish quality is high, the fur is good, the survival rate is high, and the sale price of the fish is improved. The market share is improved, the dealer satisfaction is improved, and the output value of the fishing ground is increased.
2. The large deepwater fishing net matrix is laid in the deepest and widest water area in front of a reservoir dam, the expected effect can be achieved or reached by blocking a left net and a right net, and the middle upstream of the reservoir is used as a reservoir fishing-forbidden area, so that the large deepwater fishing net matrix is well protected and can promote future fishery production to be continuously increased.
3. Because the quantity under the fish lifting part is less, the fish lifting and transporting process is short, the energy consumption is low, the labor time intensity is reduced relatively, the quality of the live fish is ensured, and the fishing device has a better recapture effect on large-size economic fish living in a deep water area.
Secondly, the design of the fish-lifting part is shown in figures 13-18.
According to the fishing specification size, design mesh size, according to the degree of depth of fish place water layer design fish-raising portion, according to the volume of fishing volume design fish-raising pocket, according to the length design fish-raising portion's of self live fish boat width, be favorable to fish-raising under the prerequisite of assurance volume.
For example, the fish lifting part of a white stone reservoir requires that the fish weight per day is not more than 4 kilograms, the fish weight per day is 3.5 kilograms per tail of silver carp, the fish weight per tail of silver carp is 5 kilograms per tail, the design mesh is 16 centimeters, the volume of 4 kilograms of fish is more than or equal to 4000 cubic meters and 10 to 15 kilograms per cubic meter, the water depth is basically 15 to 19 meters, and the fish lifting pocket is designed to be 15 meters deep.
With the excessive fishing amount, the fishing net mesh of 16cm can be enlarged to 20 cm, so that the sale pressure can be reduced, the large fishes can be ensured to be enlarged, and a good foundation is laid for the later production.
Thirdly, fishing the large-scale net array in deep water.
The first design of three large net doors, generally, the deep water net foil net door uses bamboo poles and wooden poles, a floater is added to make a net port on the water surface, a rail, channel steel and a sand bag are made a net port under the water, the net door is fixed in the water, and the width of the net door is about 1-6 meters.
The design of the deepwater large-scale network gate of the reservoir is designed according to the fishing specification and size and the length and the angle of connecting ropes at various positions according to the right-angled triangle pythagorean theorem. It is known that fish find obstacles and hazards in front by eye and sonar, especially in deep water in the absence of light. The fish leans on the sonar entirely, lets big specification's fish not feel danger, and in the unconscious entering toward the net, the leading-in second gate (fish gathering battle array net door), third gate (stranded fish battle array net door) and fourth gate (eight characters net door) of big fish have played effectual recapture to big fish gradually. The design of each net door is cracked according to the self defense, the rotating diameter and the turning ability of the fishes, so that the whole fishing process is completed by blocking, guiding, collecting, trapping and lifting the fishes.
The width of each narrowest part of each first three large net door is 30 meters, the net door is divided into two parts, each side is 15 meters, large fishes can only find one side net, the large fishes can easily and unconsciously enter the three first net doors, each net door is provided with inverted beards and can easily enter and be difficult to exit, a cross-river connecting rope is 400 meters, the half side is 200 meters, the length of a lateral rotation guide net exceeds 540 meters, the large fishes entering the wide water area (fish guide array) can lose the direction and can hardly swim backwards, the large fishes can only enter a second net, a third net and a fourth net door, a fish collecting array, a fish array, a splayed net and a fish lifting pocket are sequentially arranged, the widths of the second net door, the third net and the fourth net door are sequentially reduced, the large fishes are more difficult to swim backwards, and finally enter a fish lifting part, workers can lift the fishes, and the whole trapping process is completed.
The advantages are that:
according to the condition of fish swimming back, large-sized fish groups of large sizes exist in deep water areas in front of dams of various large reservoirs during the opening of a river, namely, the large fishes accumulated in the reservoirs all the year round (few fishing teams catch fishes in the net in the deep water areas in front of the dams), the large fishes can not be caught all the year round, and the waste of aquatic products is caused by the death of the large fishes after a certain period of time. The method aims to solve the problem of recapture of large-size fishes in a deep water area in front of a dam, prevent water from being discharged during flood discharge of the reservoir in a flood season, cause a large number of fish schools to escape, improve fishing quality, protect juvenile fish growth, accelerate sustainable development of reservoir fishery and provide good recapture guarantee. The large-scale fixed fishing net capable of fishing in the deepest water area in front of the reservoir dam and in the widest water surface realizes large and small fishing, the fish guide matrix is provided with three large net doors, the fish collecting matrix is provided with three small net doors, the net doors of the trapped fish matrix are smaller, the splayed net door of the fish raising part is smallest, and the giant fishes cannot retreat step by step and are led into the fish raising part.
