A kind of hairy crab breeding pond

Abstract

A hairy crab culture pond, comprising a dam (5), a ring ditch (6), a first shallow water area (7) and a second shallow water area (8), the dam (5) is located at the outermost side of the culture pond, and the first The shallow water area (7) is located in the middle of the culture pond, surrounded by a ring ditch (6), the outer side of the ring ditch (6) is surrounded by a second shallow water area (8), and the first shallow water area (7) is buried near the edge. There are a plurality of fixed bases (3), and a detachable isolation rod (1) is installed on the fixed base (3), and a rotating shaft (12) is arranged inside the insulating rod (1), and An isolation net (2) is wound, and the other end of the isolation net (2) can be pulled out to be connected with the isolation rod (1) on the adjacent fixed base (3). In the hairy crab breeding pond, the net fence can be rolled inside the isolation rod, and the isolation rod is movably connected to the fixed base, the installation and disassembly are simple, and the net fence can be used for many times, which reduces the cost of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a hairy crab culture pond. Background technique [0002] The scientific name of the hairy crab in the Yellow River Estuary is the Chinese mitten crab, commonly known as river crab and hairy crab. It is the freshwater crab with the largest output among crabs in my country. Since the Yellow River diverted from Shandong Dongying to the sea, a large number of hairy crabs began to be distributed in the Yellow River Delta. The Yellow River Delta Nature Reserve is the main natural habitat of hairy crabs in the Yellow River Estuary, and it is also the source of artificial breeding of hairy crabs in the Yellow River Estuary. The water quality in the area is excellent, the aquatic plants are luxuriant, and the bait organisms are rich, which provides unique conditions for the habitat, reproduction and growth of the Yellow River estuary hairy crabs. [0003] As the saying goes, "When r...

AI Technical Summary

Problems solved by technology

Although this method protects the aquatic plants very well, there are some defects: 1. The fence is tied to the bamboo poles by steel wires and then buried in the soil for use. Multi-person cooperation is completed, which consumes a lot of manpower and material resources, and the cost is high

2. Every time the net fence is removed, it is easy to turn up the mud when the net fence is pulled out from the soil, reducing the transparency of the water body
