A marine fish release boat

Abstract

The invention discloses a marine fish releasing ship, aiming to provide a releasing ship with low labor intensity, high releasing efficiency, which can effectively improve the releasing survival rate of fish fry and has good releasing effect. It includes counterweight, connecting shaft, vertical guide rod arranged on the hull, guide sleeve slidably arranged on the vertical guide rod, vertical sleeve body arranged on the hull and slidably arranged in the vertical sleeve body placement tube. The upper and lower ends of the vertical sleeve body are open, and the lower end of the vertical sleeve body extends downwards and penetrates the bottom surface of the hull, and the vertical sleeve body is sealed and connected with the bottom surface of the hull. The upper and lower ends of the placement cylinder are open, and the lower part of the inner side of the placement cylinder is provided with an inner annular limit block; inside the placement cylinder, a partition is arranged below the inner annular limit block. The dividing plate is provided with a plurality of water inlet through holes penetrating through the upper and lower surfaces of the dividing plate.

Description

Technical field [0001] The invention relates to a release device, in particular to a release vessel for marine fish. Background technique [0002] Fish marine reproduction and release refers to the fishery method in which the fish are artificially propagated and nursed and then released into the natural ocean waters where fish resources are declining, so that the natural fish population can be restored, and then rational fishing can be carried out. [0003] At present, the general method of fish release is to load the seed in a dedicated live-water ship and transport it to the releasing sea area; then use a net bag to transfer the seed to a bucket with water, and then dump the bucket to the sea in. The current fish release method requires a lot of manpower, its labor intensity is high, and the release efficiency is low; and because there is a certain height difference between the live water tank of the transport ship and the sea level, the fry may be thrown from the air to the sea...

AI Technical Summary

Problems solved by technology

The current fish release method requires a lot of manpower, which is labor-intensive and low in release efficiency; and because there is a certain height difference between the live water tank of the transport ship and the sea level, the fry are thrown from the air into the sea during release, which may also cause the fry to fall. Injury, leading to the decline in the vitality of the released seedlings or even death, seriously affecting the release effect
