What are the symptoms of fish when they are sick?
In general, we have some key points for observing the appearance of fish:
1. Body color:
If you often observe the fish you raise, you will know what its normal color looks like. If it suddenly becomes darker or lighter or even pale, it means there may be something wrong with the fish.
two。 Behavior:
It is also problematic if the fish is always lively and active, and suddenly becomes inactive or even stuck somewhere in the tank or floating on the water. On the contrary, the normally inactive fish suddenly become swimming and bumping everywhere, even if they do not stop even if they are injured, or if they float their heads and breathe with their mouth on the surface of the water, the fish have a good chance of sudden death.

The stocking proportion is generally about 40% for silver carp, 10% for bighead carp, 30% for grass and carp, and 20% for green carp and carp. Release fish culture
