Health maintenance agent for waterweeds in aquaculture pond of freshwater shrimps and crabs

Abstract

The invention relates to a health maintenance agent for waterweeds in an aquaculture pond of freshwater shrimps and crabs, belonging to the technical field of aquaculture. The health maintenance agent is characterized by comprising the following components in parts by weight; magnesium sulfate, potassium chloride, ferrous sulphate, boric acid and compound sodium nitrophenolate are weighed according to the percentage and uniformly mixed at the normal temperature; the components are uniformly mixed with the monocalcium phosphate, sodium humate, polyaluminum ferric silicate and zeolite powder according to the percentage and finally packaged. The invention is convenient to use and not influenced by the environmental condition and has low dosage; after use, the invention quickly becomes effective, has stable effect, and is capable of quickly improving the growth of the waterweeds in the pond and removing the sludge and attachments on the surfaces of the waterweeds, so that the waterweeds have developed root system, clear surface and dark green color and are healthy and stable. The contents of nitrogen and phosphorus in the pond water are reduced effectively; the environmental quality of the pond is improved; the survival condition of shrimps and crabs is improved, the calcium source of water is supplied reasonably, and the growth and the quality of the shrimps and crabs are improved.

Description

technical field [0001] The invention relates to a health maintenance agent for aquatic plants in freshwater shrimp and crab breeding ponds, and belongs to the technical field of aquaculture. Background technique [0002] The pond ecosystem has become the main water body for aquaculture production because of its simple structure and strong controllability, and the pond culture of freshwater shrimp and crab plays a pivotal role in aquaculture in my country (especially in the middle and lower reaches of the Yangtze River). Freshwater shrimp and crabs are the main economic species widely distributed in freshwater waters. They have the characteristics of fast growth, large individuals, strong reproductive ability, rich nutrition and tender and delicious meat. The main species cultivated. Freshwater shrimp and crabs are crustaceans that inhabit the bottom of the water. They often climb and crawl in the grass at the bottom of the water. They consume high oxygen and are not resista...

Problems solved by technology

This method can promote the growth of aquatic plants at a certain stage, but it cannot guarantee the health and stability of the ecological community of aquatic plants throughout the breeding cycle, resulting in vigorous growth of aquatic plants in stages, and at the same time, large-scale withering of aquatic plants in stages, which affects shrimp. Normal growth and development of crabs
