The second bait is the internal organs, especially the liver! Because catfish eat carrion, especially Egyptian catfish, they like carrion very much, so many people use animal viscera and put them in plastic bags to make holes or hooks. Generally speaking, chicken and duck intestines, pig liver and pig lungs are more common and easy to use. However, there are two points to add here: first, catfish eat carrion, but it doesn't mean that they like carrion best, so it's not only smelly fishing that can lure fish, but the effect of chicken and duck viscera is just as good! Secondly, combined with the experience of fishing friends, and through my experiments, I found that the effect of animal liver is relatively better, especially duck liver, which is particularly prominent and may be more fishy.
The third kind is loach. Misgurnus anguillicaudatus is a good thing, which is fatal to many carnivorous fish. When it comes to loach, many people may think of the "loach party" and think that it is too lethal and does not advocate it. In fact, the so-called loach party refers not to the loach hook, but to the loach nest. This is definitely not desirable, but it is not a big problem to get a few loach hooks.
The fourth kind is shrimp. Don't choose the variety of shrimp, hang the small whole one, cut the big one into sections, not only hook it, but also make a nest. But if you make a nest, it is recommended to use stinky shrimp. If it doesn't stink, put it in a plastic bag and throw it in the sun to dry. Stinky shrimp tastes strong, and catfish are easier to find a nest.
