Generally speaking, the size of groupers is not large, around 1 or below 1. If it exceeds 1, it can be said that it is very difficult to catch grouper:
1, line group: the line group for grouper fishing is similar to that for small crucian carp, with 1 as the main line and 0.6 as the secondary line;
2. Hook: The mouth of the grouper in the stream is relatively small, so you can choose the thinner No.3 sleeve hook.
3. Bait: commercial bait can be used for fishing in Dashanquan puddle, or plain bait such as corn flour can be used to lure it into the nest, and then worm bait such as earthworm bait or cricket bait can be used for fishing;
4. Fishing method: Groupers in streams tend to be concentrated in stony shadows and will not stay in one place for a long time, so it is better to walk more if you want to catch groupers in streams, and groupers in streams are impatient, so they will be blackened after eating bait, so you need to lift the pole immediately when there is black drift above the current, so as to catch groupers in streams.
