Abstract

The invention provides an indoor domestication and cultivation device and method for wild juvenile yellow-fin tunas, and belongs to the technical field of aquaculture. The device comprises a domestication pool 1; a water outlet 2 is formed in the bottom of the domestication pool 1; the water outlet 2 sequentially communicates a drainage pipeline 3, a water purification treatment assembly 4, a water pump 5, a water inlet pipeline 6 located at the top of the domestication pool 1 and an ultraviolet disinfection assembly 7 located in the domestication pool 1 in a water circulation direction; a lighting assembly 8 is arranged above the domestication pool 1; and an oxygenation assembly 9 is arranged at the bottom of the domestication pool 1. The device provided by the invention can successfullysolve the technical problem that wild young yellow-fin tunas cannot be domesticated and cultured in an indoor culture pond. Indoor domestication and breeding of the wild juvenile yellow-fin tunas arerealized for the first time.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an indoor domestication and cultivation device and method for wild juvenile yellowfin tuna. Background technique [0002] Yellowfin tuna (Latin name: Thunnus albacares, English name: yellowfin tuna), belonging to Perciformes (Perciformes), Scombridae (Scombridae), Tuna (Thunnus), is one of the important catch species of pelagic fisheries in the world. Yellowfin tuna is an important species caught in fisheries in the Pacific Ocean and has extremely high economic value. At present, artificial breeding of yellowfin tuna has not yet been carried out in China, mainly due to problems in the cultivation technology of yellowfin tuna seedlings. Contents of the invention [0003] The object of the present invention is to provide a device and method for indoor domestication and cultivation of wild juvenile yellowfin tuna. The device and method of the present invention realize the dom...
