An incubation device for reducing cannibalism of rock-dwelling cichlid juveniles in Lake Malawi

Abstract

The invention provides an incubation device for reducing juvenile fish cannibalism of Malawi lake mbuna Cichlidae. The incubation device includes a housing; an upper center of the housing is connectedto an isolation strip; the interior of the housing is divided into a juvenile fish hide region and a parent fish recreation region by the isolation strip; a lower end of the juvenile fish hide regionis connected to a labyrinth; hide balls suspend in the juvenile fish hide region; a horizontal isolation plate is connected to a lower end of an inner wall of the housing; and a water outlet is formed in the center of the horizontal isolation plate. The incubation device is high in environment simulation level, can prevent the juvenile fish from being lost, can allow healthy growth and living ofthe parent fish and the juvenile fish, can effectively enlarge the motion and hide space of the juvenile fish, can prevent the parent fishes from eating the juvenile fishes and mutual fighting betweenthe juvenile fishes, can significantly improve the survival rate of the juvenile fishes, and can improve the aquaculture economic value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an incubator for reducing residual food for cichlid juvenile cichlids in Lake Malawi. Background technique [0002] Cichlid fish, belonging to the family Cichlidae. The short ones (generally no more than 10cm) are called short breams. Because some species of broodfish protect the small fish meticulously, and even hatch their eggs in their mouths, they are also called mouth-brooding fishes. Most cichlids are irritable and like to fight. Most species have a territorial concept, and they are not easy to be invaded by their fish, and they are highly exclusive. But they take good care of their offspring and are extremely loving, so they are called cichlids.

[0003] Rock-dwelling cichlids in Lake Malawi are a kind of ornamental fish popular with consumers at home and abroad. They are colorful and diverse in variety. Oral hatching instinct degenerates from generation to generation

The inventors have obtained from experiments that the mouth-hatching instinct and species characteristics of juveniles hatched naturally from broodstock to maturity can be better maintained, but at present there is no good product for the isolated hatching device under the state of natural mouth-hatching both at home and abroad. Therefore, the inventor designed this incubation device and applied it to actual production, and achieved good results.
