High-efficiency fishing equipment and fishing method thereof

Abstract

The invention discloses high-efficiency fishing equipment for fish farming, and a fishing method utilizing the fishing equipment. The fishing equipment structurally comprises fixed piles, pulleys, windlasses, lifting ropes, a fish collecting box, a trapping net and the like; the four fixed piles are arranged in a rectangle and are fixedly mounted in a lake, a river or a pond; the distance from a fixed pile which is closest to a bank to the bank is 50 to 100 cm; a pulley is mounted at the top end of each fixed pile. The fishing method comprises the following steps: sinking the trapping net into water two days before fishing; when the fishing equipment is used, attracting the fish by baits, expelling the fish into the fish collecting box through the trapping net, and fishing out the fish to finish fishing. The area of the net required by the fishing equipment is small; human resources consumed when the fishing equipment is utilized for operating is few; moreover, the damage to fry and fingerling in fishing is low; meanwhile, when the fish is fished by the fishing method by utilizing the fishing equipment, the consumed energy resources is few, so that the operating cost is low; moreover, the fishing efficiency is high and is not affected by weather and time.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to high-efficiency fishing equipment for fish farming and a fishing method using the fishing equipment. Background technique [0002] Fish farming, also known as aquaculture, is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. According to the salinity of the aquaculture water, it can be divided into freshwater aquaculture and marine aquaculture. According to different aquaculture waters, freshwater aquaculture is divided into pond aquaculture, reservoir aquaculture, lake aquaculture, river ditch aquaculture and rice field aquaculture and other modes. [0003] At present, most of the fishing equipment used in ponds, reservoirs, lakes and other aquaculture waters in our country adopts custom-ma...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the fishing equipment used in ponds, reservoirs, lakes and other aquaculture waters in our country adopts custom-made nets or trawl nets, and the aquaculture waters are generally large, so the required nets must be larger, and the water surface of the aquaculture waters is larger. The more nets are needed, the more consumables for nets; secondly, the larger the nets used for fishing, the more manpower is required. Generally, 6-8 acres of water surface pull-net fishing requires 6-8 10 to 50 mu of water surface pull net fishing requires 8 to 10 people, 50 to 100 mu of water surface pull net fishing requires 10 to 15 people, and more than 100 mu of water surface pull net fishing requires more Therefore, the existing way of pulling net fishing needs to consume a lot of human resources. At the same time, fishing in water bodies such as large lakes and reservoirs not only requires a large number of personnel, but also requires a number of fishing boats to work together. This requires Consume a large amount of fuel oil or other energy sources, therefore, this also causes the fishing cost of this method to be high; Thirdly, the traditional pulling net fishing under the existing mode, its equipment and method are not selective to the fishing object, and the net opening of the pulling net The degree of freedom is low, and the size of the fish caught during the operation is different. Both the fry and the adult fish are caught together into the net, which will cause huge damage to the fry and fish species that are not enough for commercial specifications, and destroy them to a certain extent. Sustainability of farming; Finally, due to the poor controllability of the traditional pull-net fishing under the existing method, it is to drop the net once and then pull it up directly. However, no fish is caught or the amount of fish caught is very small; therefore, the above factors seriously affect and limit the input and effect of fishing in current fish farming
