Larval crab hoarding breeding method of hairy crab pond culture in Yellow River Estuary based on coastal saline

Abstract

The invention discloses a larval crab hoarding breeding method of hairy crab pond culture in Yellow River Estuary based on coastal saline, the technical scheme comprises seven key steps, namely: (1) alarval crab hoarding breeding area is constructed; (2) water plants are planted; (3) larval crabs are selected; (4) the larval crabs are stocked; (5) the larval crabs are processed before put in; (6)water lever is adjusted; and (7) bait is thrown and fed. The larval crab hoarding breeding method of hairy crab pond culture in Yellow River Estuary based on coastal saline by improving an enclosed form of a pond and strengthening details of larval crab hoarding breeding, not only efficiently provides a good ecological environment for the early normal growth of water plants on a central platform,the pond is built once, has benefits for many years, but also ensures that the larval crabs grow healthily, safely and rapidly.

Description

technical field [0001] The invention relates to the field of coastal aquaculture, in particular to a method for hoarding hairy crabs in ponds in the Yellow River Estuary based on coastal saline land. Background technique [0002] The scientific name of hairy crab is Chinese mitten crab, commonly known as river crab, hairy crab, crab, etc. It is the freshwater crab with the largest output among crabs in my country. Its edible part is rich in protein, fat, vitamins and minerals, and has extremely high nutrition, health care and Medicinal value. Hairy crabs are highly adaptable and widely distributed in my country. They can be found from the Yalu River in Liaoning in the north to the Leizhou Peninsula in Guangdong in the south. It can even be found in Shashi, Hubei, which is more than 1,000 kilometers away from the ocean. Since the Yellow River diverted from Dongying City in the northeast of Shandong Province and flowed into the Bohai Sea, a large number of hairy crabs began to...

Problems solved by technology

This method has indeed played a role in protecting aquatic plants, but there are also some defects that cannot be ignored. First, it needs to be re-deployed every year, which requires considerable manpower and material resources, and the cost is high; second, it is easy to turn up the mud when removing the fence , reducing water transparency

In addition, there is also the problem of extensive management in terms of specific methods for hoarding crabs
