Problems solved by technology
This kind of young fry lacking the basic survival ability of feeding, swimming and avoiding harm, etc., will be released into the natural sea due to various reasons such as lack of food and predation by medium and large fish, which will lead to a large number of deaths of released fry, thereby reducing the risk of proliferation and release. Fishery resource multiplication effect

Embodiment approach
[0044] As an embodiment of the fry training "return" type tank 7 in the present invention, the horizontal section of the fry training "return" type tank 7 is in the shape of a ring, which can facilitate the main turntable to drive the fry repellent and the automatic bait feeding tank in a ring shape. The rotation in the water channel can also avoid the space that the fry can stay in the annular water channel.
[0045] The fry training "return" type groove 7 and the impermeable inner tube 8 are all made of transparent material, and the side wall of the fry training "return" type groove 7 is provided with an outer ring distance scale 11, and the side wall of the impermeable inner tube 8 The inner ring distance scale 10 is provided, the outer ring distance scale 11 and the inner ring distance scale 10 are all set horizontally; the side wall of the fish fry training "back" type tank 7 is also provided with a water depth of 9, and the water depth of 9 is vertically set On the side ...

The invention relates to the field of multiplication and conservation of marine fishery resources, in particular to a device for acclimating and acclimating fish fry for feeding and feeding, and a method for acclimating fish fry. A kind of bait-seeking movement training device for breeding and releasing fish fry, comprising a fish fry training "back" type cylinder, a fish fry driver, an automatic bait feeding tank, a main turntable, a fry driver fixing suspension rod and an automatic feeding tank fixing suspension rod, the The fry training "back" type cylinder includes an impermeable inner cylinder and a fry training "back" type tank, and the fry driver and the automatic bait feeding tank are respectively fixed on the fry driver fixed suspension rod and the automatic feeder. The bait tank is fixed on the suspension rod, and rotates with the main turntable in the fry training "back" type tank, which can train the swimming speed and swimming duration of the fry, and enhance the ability of chasing bait and swimming escape ability of the breeding and releasing fry , so that the proliferation and release fry can chase and capture various fast-moving bait organisms in natural sea areas.
Description
technical field [0001] The invention relates to the field of multiplication and maintenance of marine fishery resources, in particular to a training device and a fry training method for multiplication and release fish fry seeking bait. Background technique [0002] Marine enhancement and release is an important measure to increase and restore marine fishery resources, increase marine fishery production, and restore the fishery ecological environment. It has become one of the methods commonly used in many countries to restore marine fishery resources. From the 1970s to the 1980s, my country began to explore marine breeding and release. Since the 21st century, my country has increased and released more than 63 billion aquatic seedlings every year, and invested more than 1 billion yuan in breeding and releasing each year. [0003] Marine proliferation and release are mainly various artificially propagated marine aquatic economic biological seedlings (fry and shrimp fry). These...
