Problems solved by technology

Bass can be tamed by beating buckets and splashing water before feeding the fish, but feeding mandarin fish with feed and / or frozen and fresh meat bait, the feeding effect is not ideal
Therefore, at present, some carnivorous fish represented by mandarin fish can only be cultured by feeding live bait fish as bait, which has high cost and low output.

Embodiment 1

[0038] The freshly hatched mandarin fish fry in the hatching tank use Artemia worms to open their mouths, and when the individual length of the fry reaches 1cm, they continue to use Artemia worms and feed for domestication in the hatching tank, and use light for intensive domestication at night;

[0039] When the individual length of the fry reaches 1.5cm, begin to use the above-mentioned taming device for taming; use the ventilation device 20 to pass the airflow from the bottom of the bait holding part 10 into the inside of the bait holding part 10, so that it is located in the inside of the bait holding part 10. The non-living bait is suspended and swims up and down under the action of airflow.

[0040] The fish oil feeding device 30 is used to bring the fish oil into the bait holding part 10 through the ventilation pipe 21 and disperse it into the bait, so as to increase the fishy smell of the non-living bait.

[0041] After observation, mandarin fish fry did not refuse to ...

Embodiment 2

[0043] The freshly hatched perch fry in the hatching tank use Artemia worms to open their mouths, and then feed them with zooplankton and microparticle feeds at regular times and at fixed points, and use lights for concentrated feeding at night;

[0044] When the individual length of the fry reaches 1.5cm, begin to use the above-mentioned taming device for taming; use the ventilation device 20 to pass the airflow from the bottom of the bait holding part 10 into the inside of the bait holding part 10, so that it is located in the inside of the bait holding part 10. The non-living bait is suspended and swims up and down under the action of airflow.

[0045] The fish oil feeding device 30 is used to bring the fish oil into the bait holding part 10 through the ventilation pipe 21 and disperse it into the bait, so as to increase the fishy smell of the non-living bait.

[0046] After observation, the perch fry did not refuse to eat, and the feeding effect was ideal.

Embodiment 3

[0048] The freshly hatched sandfish fry in the hatching pond use Artemia larvae to open their mouths, and then feed them with zooplankton and microparticle feed at regular times and at fixed points, and use lights for concentrated feeding at night;

[0049] When the length of the individual fry reaches 1 cm, start to use the above-mentioned taming device for taming; use the ventilation device 20 to pass the airflow from the bottom of the bait holding part 10 into the inside of the bait holding part 10, so that the inside of the bait holding part 10 The non-living bait is suspended and swims up and down under the action of airflow.

[0050] The fish oil feeding device 30 is used to bring the fish oil into the bait holding part 10 through the ventilation pipe 21 and disperse it into the bait, so as to increase the fishy smell of the non-living bait.

[0051] It was observed that the fry of sandfish did not refuse to eat, and the feeding effect was very satisfactory.

Abstract

The invention relates to the field of fish breeding, and mainly relates to a feeding habit domesticating device and method for carnivorous fish. The feeding habit domesticating device comprises an aeration device, a fish oil feeding device, and a bait containing component disposed in water, and outlets of both the aeration device and the fish oil feeding device are communicated with the bottom of the bait containing component. When the feeding habit domesticating device is in use, the bait containing device containing bait is put in water, and normally formula feed cheaper than living bait is selected as the bait; airflow is pumped into the bait containing component from the bottom thereof through the aeration device, then the bait positioned inside the bait containing component is raised with the airflow to be in the status of vertical floating motion, at the same time, fish oil with strong fishlike smell is fed into the bait containing component from an air inlet through the fish oil feeding device to be evenly fixed with the bait so as to further make fish take the fed bait for swimming live fish, and the fish are promoted to eat the non-living bait so as to achieve the purpose of feeding habit domesticating.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a taming device and a taming method for carnivorous fish. Background technique [0002] Carnivorous fish, such as mandarin fish and snakeheads, usually only eat live bait. Due to the high price of live bait, the cost of fish farming will further increase. Bass can already be tamed by beating the bucket and splashing water before feeding the fish, but the feeding effect of mandarin fish is far from satisfactory by feeding mandarin fish with feed and / or frozen and fresh meat bait. Therefore, some carnivorous fishes represented by mandarin fish can only be cultured by feeding live bait fish as bait at present, and its cost is high and output is low. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a taming device and a taming method for carnivorous fish. [0004] To achieve the above object, the present invention adopt...
