Below the surface of the water is 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 conspicuous animals of that underwater ecosystem. They capture the imagination. The presence or absence of certain species can say something about the ecosystem. For example, species such as tench or rudd like to live in clear water with aquatic plants. A bream or a carp is somewhat less picky. Some species live in both fresh and salt water, depending on their life stage.

The Water Board manages water and thus has a lot to do with fish. There are several aspects to that:

  • Fish migration

    We are working to solve fish migration bottlenecks so that fish can move freely from one water to another.

  • Fish-friendly mowing

    When mowing aquatic plants, we take care that it causes as little harm to fish as possible.

  • Fish mortality

    If you see dead fish or fish in distress, please report it to us. If there are multiple fish, there may be a water quality problem.

  • Fishing rights and fishing policy

    On many of these waters we issue fishing rights to sport and professional fishermen. 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. Do you see them? Report it to us.
