A method for anti-stress domestication of farmed fish and a device based on the method

Abstract

The invention relates to a cultured fish type anti-stress domestication method and a device based on the method, and belongs to the technical field of pond culture. According to the cultured fish type anti-stress domestication method, an overwater automatic traveling device is used for dragging a fishing net with meshes of being larger than fish bodies and having a rigid framework to move back and forth in water of culture pond, so that cultured fishes in the pond gradually adapt to net dragging operation, and the loss caused by scare of the fishes during fishing and dragging is reduced. The device based on the cultured fish type anti-stress domestication method comprises a rectangular frame defined by a horizontal floating rod (7), a sinking rod (9) and a pair of vertical fixing rods (10), wherein a large-mesh net sheet (8) is fixedly arranged in the rectangular frame; the fixing rods (10) are fixedly connected with a horizontal connecting rod (6); the connecting rod (6) is fixedly connected with a floating pontoon (1); the floating pontoon (1) is provided with a solar panel (2), an accumulator (3), a controller (4) and a propeller (5); the rotation direction of the propeller is switchable.

Description

technical field [0001] The invention relates to a method for anti-stress domestication of cultured fish and a device based on the method, belonging to the technical field of pond culture. Background technique [0002] Pond culture is the main aquaculture method in my country, which has the advantages of high yield and good benefit. Pull net fishing is generally used for pond fishing. When pulling the net, the fish will have a strong stress response due to fright and stimulation, resulting in abnormal fish metabolism and damage to the fish body, causing scales to fall off, body surface bleeding, and quality decline, which not only affects the sales price, but also affects survival during transportation. In severe cases, it can lead to a large number of deaths. Contents of the invention [0003] The present invention proposes a domestication method and device that can enhance the stress resistance of farmed fish to the straining net. During the breeding process, the domest...
