Embodiment 1

[0033] A method for cultivating broodstock of the copperfish by using the in situ running water of the hull, the steps of which are:

[0034] 1. Hull transformation: there will be a certain tonnage and cabin area (10m 2Above) fishing or transport vessels are transformed into ship boxes suitable for broodstock domestication. The hull transformation ship consists of management area 1, breeding area 2, bow area 3, first sealed cabin 4, feed room 5, rest room 6, experiment room 7, storage room 8, sidewalk 9, ship box body 10, second Sealed cabin 11 is formed, and its connection relation is: breeding area 2 links to each other with management area 1, bow area 3 respectively, and management area 1 includes the first sealed cabin 4, feed room 5, rest room 6, experiment room 7, storage room 8. The first sealed cabin 4 is connected to the rest room 6, the experiment room 7, and the breeding area 2 respectively; the rest room 6 is connected to the feed room 5 and the first sealed cabin...

Abstract

The invention discloses a method for breeding parental coreius guichenoti by hull in-situ flowing water. The method includes steps: (1) hull transformation, to be more specific, transforming a fishingor transporting ship with tonnage and cabin area into a tank for parental fish domestication; (2) hull placement, to be more specific, placing a transformed hull offshore, and keeping the hull stableand keeping smoothness in water exchange of the tank; (3) parental fish collection and breeding, to be more specific, selecting injury-free robust individuals from coreius guichenoti captured by fishermen, subjecting to disinfection treatment with strong chlorine, and releasing into the tank; (4) feeding with feed, to be more specific, feeding with feed in morning and evening; (5) fish disease prevention, to be more specific, in flood seasons, feeding with medicinal bait, and adding vitamins on the basis of the feed; pouring strong chlorine which is a sterilization and disinfection medicine to the tank to prevent diseases. The method is feasible, convenient and simple in operation, defects of proneness to death and poor gonad development of parental coreius guichenoti bred in ponds, net cages, indoor circulating water systems and the like are effectively overcome, and a solid foundation is laid for success of artificial propagation.

Description

technical field [0001] The invention belongs to the field of aquaculture, and more specifically relates to a method for cultivating broodstock of the copperfish with in-situ running water in the hull, including hull modification, hull placement, backup broodstock collection and stocking, feed feeding and fish disease prevention, and is especially suitable for Breeding of broodstock in captivity of the roundmouth copperfish. Background technique [0002] The round-mouthed copperfish (Coreius guichenoti) belongs to Cypriniformes (Cypriniformes), Cyprinidae (Cyprinidae), Gotiongiae (Gotiongiae), copperfish genus, produces floating eggs, is a river migratory fish, and its gonads are developed Highly dependent on the special habitats in the middle and lower reaches of the Jinsha River. In recent years, with the step-by-step development and operation of the Jinsha River cascade power stations, the habitat of the copperfish has been reduced, the migration channel has been blocked,...
