Abstract

The invention discloses a river crab culture water treatment method. The treatment method comprises the following steps: cleaning a pond; fertilizing water and hanging ecological restoration bags; preventing and treating filamentous algae such as moss and the like; controlling blue-green algae outbreak; solving the problem of water quality index abnormity; and treating stress reaction and poisoning phenomena in low-pressure muggy weather and treating dark green water and red black water in the later period of culture. The river crab culture water treatment method has the beneficial effects that the treatment method is suitable for river crab breeding, physical, chemical, microorganism and biological new material products free of secondary pollution are used in the breeding process, secondary pollution is avoided, the problems of moss and blue-green algae outbreak and the like are effectively controlled, pesticide and antibiotic products are not needed in the breeding process, the breeding is easy, the quality of river crabs is good, and breeding benefits are high.

Description

technical field [0001] The invention relates to a treatment method, in particular to a water treatment method for river crab culture, and belongs to the technical field of river crab culture application. Background technique [0002] River crabs are arthropods belonging to the mitten crab family Crabidae. River crabs often live in caves on the mud banks of rivers, lakes, and lakes. They are nocturnal. The carapace formed by the combination of its head and chest is square and hard in texture. It has a pair of eyes, and two pairs of very sharp crab teeth on the sides; the surface of the chelicerae is covered with fluff, and there are 4 pairs of gaiters behind the chelicerae, the sides are flat and long, the abdominal limbs have degenerated, the abdomen of females is round, and the abdomen of males is round. The abdomen is triangular, and it feeds on fish, shrimp, animal carcasses and grain, and often migrates to the estuary where it goes out to sea every autumn to lay eggs. ...
