CATDOLL: How to grow river clams in winter

Pay special attention to the temperature. Also pay attention to the following three points.

1. At present, river mussels are mostly cultivated by hanging and cage cultivation. The hanging cultivation methods include single hanging cultivation and string cultivation with two or more clams hanging on a line. The number of cages depends on the size of the cage (net cage, net clamp), and it is generally appropriate for each clam to be able to touch the bottom of the cage.

2. Pearl river clams are generally cultured in ponds with 800-1200 clams per mu; in ponds with 600-800 clams per mu. The culture density depends on the body weight and fatness. The physical, chemical and biological factors such as water flow and water depth increase or decrease with the size of the clams.

3. Mussel farming has become the main production content of the comprehensive development and utilization of the outer pond fishery in our city. In the ponds mainly for pearl breeding, grass carp, bream, crucian carp, mandarin fish, yellow catfish, etc. can be raised in appropriate amounts, as well as a small amount of fish.

River clams belong to cold water, so their metabolism will slow down in winter, so those farmed outdoors will not die in winter.
