A device and method for group feeding and tank dumping of green-finned horse-faced fish juveniles induced by weak light

Abstract

The invention belongs to the technical field of aquaculture and breeding, and in particular relates to a device and method for group feeding and tank dumping of young green finfish induced by weak light. It includes a breeding pond, a structural skeleton, a control system and an actuator; the breeding pond includes a high water level fish pond and a low water level fish pond, and the high water level fish pond and the low water level fish pond are connected by a siphon; the structural skeleton is arranged between the high water level fish pond and the low water level fish pond Between the fish ponds, the structural skeleton includes a fixed bracket, a bait feeding device and an attracting light, and the bait feeding device and the attracting light are fixed on the fixed bracket through a horizontal support rod; the control system is connected with the actuator, and the control system controls the execution Institutions perform related operations. By transforming the lighting equipment in the breeding workshop, on the premise of satisfying the daily breeding management, the bait utilization rate of the juvenile green finfish can be improved, and the survival rate of the seedlings can be improved; it can effectively reduce the physical damage to the juvenile fish by pouring the pond, and improve production efficiency and save farming costs.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and breeding, and in particular relates to a low-light-induced greenfin puffer fish juvenile group feeding and pooling device and method. Background technique [0002] Green-fin pufferfish, bony fish steel, single-horned pufferfish, commonly known as rubber fish, skinned fish, pig fish, cobbler fish. Distributed in China, North Korea and Japan, it is a warm-temperature bottom sea fish, inhabiting sea areas with a water depth of 50 to 120 meters. Hi-cluster, there is obvious vertical movement during the day and night during overwintering and spawning, floating during the day and sinking at night, and the vertical movement during the day and night is not significant during the feeding period. The diet is more mixed, mainly feeding on plankton, and feeding on mollusks, corals, fish eggs, etc. The body is flat on the left and right, covered with hard and fine scales, forming strong skin like tan...

AI Technical Summary

Problems solved by technology

[0003] The existing fish fry feeding techniques include manual sprinkling and mechanical timing and fixed-point feeding, but the bait sedimentation and long feeding time of the fry during the feeding process result in low feeding efficiency, and some fry fail to feed, which eventually leads to individual weakness or death of the fry

[0004] At the same time, the existing pond pouring technology is limited to traditional net fishing or water basin pouring, which will cause mechanical damage to fry during the pouring process, and the work efficiency is low
