What are the key points to note when catching fish?

1. Choose a clear day with lower nighttime temperatures to start hauling the net; do not haul the net on overcast or rainy days, when fish are gasping at the surface, or when fish are sick.

2. Feeding should be stopped or reduced the day before net fishing; do not feed heavily just to increase the fish's body weight. The day before catching, remove stakes, branches, floating debris, and other objects from the pond to reduce the time spent hauling the net and sorting fish, minimizing losses.

3. For the first haul, start setting the net from 1/3 to 1/2 of the pond, to prevent too large a catch from being sorted in time and causing injury and death to the fish; this not only ensures the fish are not harmed or are less harmed, but also ensures fresh live fish reach the market.

4. While sorting fish and loading them onto vehicles for market, arrange for people to add fresh water to the pond being net-fished or turn on the aerator, continuing until after sunrise, then stop the water or the machine according to the situation.

5. Because net fishing easily stirs up organic matter from the bottom, depending on water quality, about 5 kg of quicklime per mu can be mixed with water and splashed over the whole pond, so that the organic matter stirred up by the net coagulates and sinks to the pond bottom.
