cold water

(e.g. local lakes)

At first glance, cold waters are much less species-poor than waters in the temperate and tropical zones and, on closer inspection, offer a lot of interesting things.
The underwater flora, which grows mainly in the shore area, is used by many cold-water animals as a nursery, as a hiding place, but also as a hunting ground.

Small perch, which gather in schools to be better protected as a group, the pike, which lies motionless in wait and usually allows divers to get very close, burbot, which live very site-faithful and show little shyness towards humans, are just a few of the highlights that our cold water lakes have to offer. The connection between water quality and the abundance of species and individuals is also demonstrated to the diver. A wide variety of habitats are often found together in a very small space.

Steep cliff faces alternate with meadows of algae , sections covered with mud with the gravel subsoil in front of stream confluences. Life in our native lakes may not be as colorful as in a tropical coral reef, but on closer inspection it unfolds in a very diverse way.
