Germany's coarse fishing season runs year-round for carp, pike and perch on most stillwaters. Trout and salmonid rivers are typically closed from late autumn through March in most states. Carp fishing peaks from May through September, with warm June and July nights producing the best sessions on larger lakes. Zander and pike fishing is at its best in autumn and winter (October–February) when the water cools and fish feed more actively. Bavaria's alpine lakes and the Bavarian lakes district are particularly productive in early summer.
