Description

River crab culture water treatment method

Technical Field

The invention relates to a treatment method, in particular to a river crab culture water treatment method, and belongs to the technical field of river crab culture application.

Background

The river crab is an arthropod of Eriocheir sinensis family, and is usually cave in mud bank of river and lake, and moves at night, the head and chest nail formed by combining head and chest is square and round, and has hard texture, a pair of eyes at the front end of body, and two pairs of very sharp crab teeth on the side; the chela surface is full of villi, 4 pairs of feet are grown after the chela, the chela is flat and long, the abdominal limbs are degenerated, the female abdomen is round, the male abdomen is triangular, the chela is fed by fish, shrimps, animal corpses and grains, and the chela is often migratory to the estuary of the sea to lay eggs every autumn.

During the culture process of river crabs, pesticides, chlorine preparations and other secondary pollution products are used, moss frequently appears in the river crabs in a season of 10-20 ℃, blue algae easily appears at the temperature of over 25 ℃, the culture cost is high, and the efficiency is low. Therefore, the river crab culture water treatment method is provided aiming at the problems.
