Background

The following problems were found by conducting an on-site investigation with respect to the current state of fishing.

1. In the spring, the fishing yield of each large reservoir (four months and five months) is low and unstable, and the specification of flowers and silver carps is smaller.

2. The fishing net foil of each reservoir has small laying area and narrow fish lifting pocket, so that the live fish is seriously worn in the net, the death rate is high in the temporary transportation and cultivation process, and the dealer reacts strongly, so that the wholesale price of the aquatic products is lower.

3. The net foils are mainly laid at the upstream in the reservoir, the number of the net foils is between 8 and 15, and the number of the fish lifting pockets is between 20 and 30: 1. reduces the ingestion space of fish and blocks the fish back-stream channel. 2. The number of the fish lifting pockets is too large, the fish lifting times are too large, the young fish is easy to be injured after being screened for multiple times, and the growth speed of the young fish is slow, so that the growth is stopped.

4. The yield of each large reservoir tends to decrease year by year, and the number of caught large-size fishes is reduced.

A method for laying a network array is provided.

1. One design of the multiple nets (blocking nets) is shown in fig. 20, and the net size is designed according to the fishing specification. The upper part of the figure 20 is a top line, a plurality of circles on the top line represent a plurality of floats, the lower part is a bottom line, a plurality of rectangles on the bottom line represent a plurality of sinkers, two sides of the top line are provided with top line connecting rings, two sides of the bottom line are provided with bottom line connecting rings, and the installation of the binding rope is facilitated. The net may be made of polyethylene.

When the weight of the back-caught fish body is more than 3.5 kg, the mesh specification is 16 cm, the height of the guide net is designed according to the deepest water level of the lower net position of the reservoir, the water depth can be equal to 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 sedimentation force of the guide net are designed according to the storm flow velocity of the reservoir.

For example: the internal test adopts a large net array in front of the guanyin pavilion reservoir dam, the mesh specification is 16cm, the guide net is 58 meters high, more than six floats are provided, and more than two sinkers are provided.

The fish is caught in the white stone reservoir, and as a result, the obtained fish has relatively complete species, relatively high yield, good fish skin and hair, high survival rate, more large-specification fish and little and juvenile fish. And the large-scale net array of the deep water fishing is tested in five reservoirs (a white stone reservoir, a guanyin pavilion reservoir, a fresh water reservoir, a firewood river reservoir and a soup river reservoir) in the water source area of Liaoning province, the large-scale net array is removed after the test, and the test conditions are summarized as follows:

1. The fishing is stable and high in yield, the quality of the fish is high, the fur is good, the survival rate is high, and the sale unit price of the fish is improved. Improves market share, is satisfied by distributors, and increases the yield of the fishing ground.

2. The large-scale net array for deep water fishing is laid in the deepest and widest water area in front of the reservoir dam, the two nets can complete or achieve the expected effect after being blocked, the upstream of the reservoir is used as a reservoir fishing forbidden area, and the large-scale net array for deep water fishing is better protected and can continuously increase in future fishery production.

3. Because the number of fish lifting parts is small, the fish lifting transportation process is short, the energy consumption is low, the relative labor time intensity is reduced, the quality of live fish is ensured, and the fishing device has a better fishing effect on large-specification economic fish living in a deepwater area.

2. The design of the fish lifting part is shown in fig. 13-18.

According to the size of the fishing specification, the size of the mesh is designed, the depth of the fish lifting part is designed according to the water layer where fish is located, the volume of the fish lifting pocket is designed according to the fishing amount, the width of the fish lifting part is designed according to the length of the living fish boat, and the fish lifting is facilitated on the premise of guaranteeing the volume.

For example, the fish lifting part of a white stone reservoir requires that the fishing weight per day is not more than 4 kilo, the fishing weight of the silver carp is 3.5 kg/tail, the silver carp is 5 kg/tail, the design mesh is 16 cm, the required volume of 4 kilo of fish is more than or equal to 4000 cubic meters, the water depth is basically 15-19 meters, and the fish lifting pocket is 15 meters deep.

With the excessive fishing amount, the fishing net can be enlarged to 20cm by 16 cm, so that the sales pressure can be reduced, the fishing of big fish and small fish can be ensured, and a good foundation is laid for the subsequent production.

3. Large-scale net array for deep water fishing.

The first three big net doors are designed, and the general deep water net foil net doors all use bamboo poles and wood poles, floats are added to serve as net openings on the water surface, rails, channel steel and sand bags are used as net openings under the water surface, the net doors are fixed in the water, and the width of the net doors is about 1-6 meters.

The design of the deep water large-scale net array net gate of the reservoir is designed according to the size of the fishing specification, and the length and the angle of connecting ropes at all positions are designed according to the Pythagorean theorem of right-angled triangles. It is known that fish find obstacles and hazards ahead by eyes and sonar, especially in deep water without light. The fish is totally by sonar, so that large-size fish does not feel dangerous, unknowingly enters the net, and the large fish is gradually guided into a second gate (a fish collecting array gate), a third gate (a fish trapping array gate) and a fourth gate (a splayed net gate), so that the large fish is effectively caught back. Every design of the net door breaks according to the defenses, the rotation diameters and the turning capacity of the fish, and the whole fishing process is completed by blocking, guiding, collecting, trapping and lifting the fish.

The width of each narrowest part of the first three large net doors is 30 meters and is divided into two halves, each side is 15 meters, a large fish can only find one side net, the large fish can easily and unknowingly enter the three first net doors, as each net door has inverted whiskers and is easy to enter and difficult to exit, the transverse river connecting ropes are 400 meters, the half sides are 200 meters, the length of the side-rotation net guide is over 540 meters, the large fish can get into a wide water area (a fish guide array) in such a way to lose directions and hardly back out, the large fish can only enter the second net door, the third net door and the fourth net door, the second net door, the third net door, the fish trapping array, the splayed net and the fish lifting pocket are sequentially reduced, the large fish is more difficult to back out, and finally a large amount of large fish can enter the fish lifting part, so that workers can lift the fish, and the whole fish catching process is completed.

The advantages are that:

According to the condition of fish back-stream, in the deep water area in front of each large reservoir dam during the open river, large-scale group fishes exist, namely, the large fishes accumulated in the reservoir all the year round (few fishing teams catch fish in the deep water area in front of the dam) can not be caught until the past, and the waste of aquatic products is caused by death of the large fishes for a certain period of time. In order to solve the back-catching of large-size fishes in deep water areas in front of a dam, prevent flood discharge and water drainage in a flood season of a reservoir and cause a large number of fish shoals to escape downwards, improve the fishing quality, protect the growth of young fishes, accelerate the sustainable development of reservoir fishery and provide good back-catching guarantee. The fishing net can be fixed in a large-scale place with the deepest water area and the widest water surface in front of the reservoir dam to realize large and small fishing, the fish guiding array is provided with three large net doors, the fish collecting array is provided with three small net doors, the fish trapping array net doors are smaller, the splayed net doors of the fish lifting part are minimum, so that large fishes can not gradually retreat to be led into the fish lifting part, the large fishes can be lifted at the fish lifting part on the water surface, the large fishes accumulated in the past of the reservoir dam in the years can be caught, small fish young fishes can be discharged, the stable high yield is realized, and the fishing tool fishing method for promoting the yield increase and the efficiency of fishery is provided.
