Beneath the water's surface lies a whole world of aquatic life. This ranges from algae and aquatic plants to small creatures such as beetles, snails, dragonfly larvae, and... fish.

Fish are the most visible and striking animals in this underwater ecosystem. They capture the imagination. The presence or absence of certain species can say something about the ecosystem. Species such as tench and rudd prefer to live in clear water with aquatic plants. Bream and carp are less choosy. Some species live in both fresh and salt water, depending on their stage of life.

The water board manages the water and therefore has a lot to do with fish. This involves various aspects:

  • Fish migration

    We are working to resolve bottlenecks for fish migration so that fish can move freely from one body of water to another.

  • Fish-friendly mowing

    When cutting aquatic plants, we take care to cause as little damage as possible to the fish.

  • Fish mortality

    If you see dead fish or fish in distress, you can report this to us. If there are multiple fish involved, there may be a problem with the water quality.

  • Fishing rights and fishing policy

    We issue fishing rights to recreational and commercial fishermen on many of these waters. How this works is described in our fishing policy.

  • Crayfish

    The American crayfish is an invasive exotic species and does not belong in our waters. If you see any, please report them to us.
