Many fishermen prefer nice weather, but those who fish in the rain catch more. At least that’s what they say. But it is not quite that simple. Because often it makes a difference if you fish before, during or after it rains. First you have to understand what the rain can do both above and below the water. Rain leads to a change in air pressure. These changing weather conditions usually have a direct influence on the fishing success. Especially the oxygen content in the water changes and the fish react to this. After the rain there is more oxygen in the water and food gets into the water through the turbulence. Therefore predatory fish are much more active for the next hours than before. I was able to take advantage of this effect in my last session. To increase my chances of catching the catfish I fished with one rod for carp and the other for catfish. On one rod I attached a boilie with high attraction (Starbaits Marine 20mm) and on the other rod I attached a pose with a bundle of roundworms. With the result I was surprised I could catch my first catfish with a size of 1.43m and 1.02m, during the day. But also on the carp rod I got action with a white amur 8.92lbs.
