Inland marine culture system and culture method thereof

Abstract

The invention discloses an inland marine culture system and a culture method thereof. The inland marine culture system comprises an indoor factory culture system and an ecological culture system, wherein the indoor factory culture system comprises an indoor culture factory, a culture dirt treatment system and a first biological purification system; the first biological purification system, the culture dirt treatment system and the indoor culture factory coordinate with each other and form a first culture circulation waterway; the ecological culture system comprises a sludge treatment culture system, a circulating water sedimentation separation system and a second biological purification system, the second biological purification system is communicated with the circulating water sedimentation separation system, and the second biological purification system, the circulating water sedimentation separation system and the sludge treatment culture system coordinate with each other and form a second culture circulation waterway. A continuous circulating water culture self-supporting system required by interior of the ecological culture system is provided, the problems of high discharge and environmental protection of the traditional ecological culture system can be alleviated, energy source is fully utilized, and good economic and social benefits are realized.

Description

technical field [0001] The invention relates to the technical field of seawater aquaculture, in particular to an inland seawater aquaculture system and a cultivation method thereof. Background technique [0002] At present, it is said that closed recirculating aquaculture cannot realize a true closed cycle, and the yield and benefit are low, so it cannot enter inland areas for development, resulting in a gap in the field of inland seawater aquaculture. At the same time, indoor factory aquaculture in a closed recirculating aquaculture system requires about 5%-10% of the daily circulating water exchange volume, and because the inland area is far away from the sea, the cost of water supply is high, the cost of aquaculture is increased, and the residue produced by aquaculture Bait feces need to be specially treated, which will further increase the cost of breeding. In addition, the ecological breeding system suitable for inland areas, such as soil pond farming, still has the pr...

AI Technical Summary

Problems solved by technology

[0002] At present, there are still gaps in the field of inland marine aquaculture due to the fact that closed recirculating aquaculture cannot achieve a true closed cycle, and the yield is low and cannot enter inland areas for development.

At the same time, indoor factory aquaculture in a closed recirculating aquaculture system requires about 5%-10% of the daily circulating water exchange volume, and because the inland area is far away from the sea, the cost of water supply is high, the cost of aquaculture is increased, and the residue produced by aquaculture Bait feces need to be specially treated, which will further increase the cost of breeding

In addition, the ecological breeding system suitable for inland areas, such as soil pond farming, still has the problems of large-scale sewage discharge and salinization, and it also consumes more nutrients for the cultured organisms and plants themselves, and the cost of breeding is high. Economic benefit is poor
