Fish moving device for culture work ship

Abstract

The invention relates to a fish moving device for a culture work ship. One of a pair of fish culture water cabins is a fish culture water cabin to be transferred, and the other fish culture water cabin is a fish culture transferring and receiving water cabin; a small fish feeding and inducing device is arranged in the fish culture water cabin to be transferred, a fish moving channel is arranged between the pair of fish culture water cabins of the culture work ship, and fish moving channel end covers controllable in opening and closing are arranged at the two ends of the fish moving channel; the inner wall of the fish moving channel is provided with fish moving channel fish luring lamps and fish body laser detectors at intervals in the length direction; a controlled linkage mode of the fish moving channel fish luring lamps and the fish body laser detectors is that when the fish body laser detectors detect live fishes, the fish moving channel fish luring lamps in front of the corresponding fish body laser detectors are turned on, and the fish luring lamps behind the corresponding fish body laser detectors are turned off. The fish luring lamps in the fish moving channel are controlled by laser fish body detection transmitters / receivers to be turned on / off, fish schools are induced to enter the fish culture water cabin to be transferred along with the fish moving channel, and the efficiency of transferring cultured fishes is improved.

Description

technical field [0001] The invention relates to a fish transfer device in a fish farming cabin, in particular to a fish transfer device for a farming boat. Background technique [0002] As a new type of fish farming facility, farming boats can solve the problem of water pollution caused by traditional cage farming due to its long-term fixation in a certain water area due to its flexible mobility. And the breeding area can be transferred in time before the bad weather comes. [0003] The breeding boat is a boat-shaped breeding facility with multiple fish tanks inside. Fish schools with different growth cycles are cultured in different fish tanks, which can ensure the output of adult fish throughout the year. Because the space of each fish farming water tank is certain, in order to maximize the use of space and reduce the cost of water body exchange and breeding, a higher breeding density is used for breeding when the fish body is small. And after the growth volume of fish g...

Problems solved by technology

Conventional methods of moving fish using nets, fish suction pumps, etc. will easily cause damage due to the extrusion of the fish body, so there is a need for a fish moving structure that is completely harmless to the fish body and does not affect the structural strength of the farming vessel.
