A kind of yellowtail low stress operating device and using method thereof

Abstract

The invention provides a low-stress operating device for yellowtail yellowtail and a method for using the same, belonging to the field of marine aquaculture equipment engineering. Cover plate, operating platform water inlet pipe, operating platform water outlet pipe, lighting system, video capture and window system, wireless transmission system and sliding controller; after the fish is placed in the concave fish tank, adjust the cover plate to cover the fish head and fish tail, The surrounding of the fish body and the head and tail are covered with soft materials, which can effectively prevent the fish body from struggling violently and tail flicking, and reduce the damage to the fish body. , helps to keep the fish quiet, reduce stress and struggle, can greatly reduce the physiological stress and operational loss to the fish, help improve work efficiency, and provide guarantees for accurate measurement of biological traits and health inspection of fish.

Description

technical field [0001] The invention belongs to the field of mariculture equipment engineering, and in particular relates to a yellowtail yellowtail low-stress operating device and a use method thereof. Background technique [0002] Amberjack is an oceanic economic fish that is widely distributed in global waters and has the characteristics of long-distance migration. It is large in size, fast in growth, high in economic value, rich in nutrition, and its meat quality is comparable to that of salmon and tuna. and other ingredients are favored by domestic and foreign consumer markets. my country's yellowtail is mainly distributed in the Bohai Sea, the Yellow Sea and the East China Sea. It is suitable for industrialized circulating water and deep-water anti-wind and wave cage culture. It is an ideal fish species for the development of deep-sea large-scale facility farming in my country. The breeding technology is in line with the strategic needs of the green development of mari...

AI Technical Summary

Problems solved by technology

In the process of production practice and experimental research, we found that yellowtail amberjack, whether it is farmed fish or broodstock, shows a violent struggle response under the condition of artificial capture, and its strength is too strong to be controlled manually.

Even under anesthesia, the amberjack exhibited a stress response of prolonged violent struggle, and violently hit the container wall with its head and tail, causing scales to fall off, and bleeding injuries from the head and tail

Fish with a severe stress response may die within a short period of time after returning to the breeding or breeding tank after the operation, causing unnecessary losses
