Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture, in particular to a large-scale seawater fry factory grading cultivation system. BACKGROUND

[0002] Developing deep-sea aquaculture is an important measure to promote the high-quality development of the "blue granary". Due to the uncontrollable environmental conditions and relatively extensive production operation mode, deep-sea aquaculture often needs to release large-scale fry to improve the survival rate and reduce the risk of aquaculture. At present, one of the key links restricting deep-sea aquaculture is that large-scale fry is difficult to be stably supplied and the adaptability of fry land-sea relay transition is poor. Traditional large-scale seawater fry cultivation methods mostly use open or semi-open pond culture mode, which has problems such as difficulty in water quality regulation, extensive fry grading management, weak disease prevention and control ability, etc., resulting in low fry survival rate, uneven growth rate, and large size difference, which is difficult to meet the demand of modern seawater aquaculture for high-quality, healthy and standardized fry.

[0003] In the field of factory farming, although some recirculating aquaculture systems have been applied to seawater fry cultivation, existing technologies mostly focus on the large-scale cultivation of single-stage fry, and lack the function of grading and fine cultivation of fry at different growth stages. Specifically, newly hatched fry, juvenile fish and set-size fry have significant differences in terms of environmental requirements, feed types and feeding strategies, disease prevention and control priorities, etc. Traditional cultivation systems cannot achieve precise environmental regulation and grading management of fry at different stages, resulting in low fry cultivation efficiency and serious resource waste.
