Seawater indoor culture method

Abstract

The invention provides a seawater indoor culture method. The seawater indoor culture method comprises the following steps of (1) constructing a water circulation system formed by connecting an algae culture pond, a microorganism purification pond and a fish pond in series; (2) injecting the artificial seawater into the algae culture pond, the microorganism purification pond and the fish pond; and (3) periodically putting an algae nutrient agent into the algae culture pond and putting a microbial nutrient agent into the microbial purification pond. The seawater indoor culture method has the beneficial effects that an ecological system in which the algae culture pond, the microorganism purification pond and the fish pond are mutually coupled is constructed, seawater algae are cultured in the algae culture pond, probiotics are cultured in the microorganism purification pond, seawater aquatic animals are cultured in the fish pond, artificial seawater is injected, nutrient elements needed by algae and microorganisms are regularly added into the system, efficient conversion and absorption of the microorganisms and the algae on toxic waste such as ammonia nitrogen discharged by the aquatic animals in water are achieved, and meanwhile the system has the advantages of being free of water change and capable of achieving high-density cultivation.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a seawater indoor cultivation method. Background technique [0002] With the increase of human demand for seafood, seafood fishing has been unable to meet people's needs, coupled with the destruction of marine ecosystems caused by seafood fishing, the country is gradually tightening restrictions on seafood fishing, so vigorously developing mariculture is the future trend . my country has a long history of mariculture. Traditional mariculture is carried out in coastal areas, and marine culture is carried out by setting up cages in the offshore. The pollution caused by the aquaculture environment deteriorates and it is difficult to meet the growing demand for seafood. Therefore, it is very urgent to develop inland marine aquaculture systems. At present, the existing inland mariculture systems include seawater recirculating aquaculture system and farming symbiotic mariculture s...

Problems solved by technology

However, the nutrients needed by plants and microorganisms in natural seawater are very scarce, and it is difficult to efficiently purify ammonia nitrogen and other wastes discharged by fish and shrimp in small water bodies, so the breeding density is low. At the same time, various inorganic salts in natural seawater will interfere with plant The detection of micronutrients required by microorganisms makes it impossible to evaluate the content of micronutrients in water, so it is difficult to continuously detect and add micronutrients, and higher plants can not absorb nitrate and phosphate faster than lower algae
