To catch rainbow trout, we must first choose a good fishing spot. Generally speaking, in the deep water areas of reservoirs, lakes, rivers and large waters, the density of rainbow trout is high, and they generally do not come to the shore to feed. Therefore, it is very important to choose a good fishing spot on the shore of these waters. Secondly, we should choose fishing tackle and fishing method. Fishing rainbow trout, it is best to use sea poles, because the fishing group of sea poles is more flexible, and the configuration of fishing groups is also very convenient, which can be adjusted at any time according to the changes of fish conditions. Of course, if you are fishing with a hand pole, you can also fish rainbow trout by throwing a pole. Thirdly, we should pay attention to choosing the right bait. It is best to use earthworm as bait for rainbow trout fishing, because earthworm is the most common and easy to find bait. Of course, if you are fishing with a pole, you can also use commercial bait, such as "big plate crucian carp" and "9 1", and the effect is also good, but when fishing, you should pay more attention not to let the hook break the earthworm, so as not to affect fishing. Finally, it is necessary to pay attention to observation. In the process of fishing, once the fish situation changes, it must be adjusted in time.
