Stocking measures must primarily be intended and suitable for compensating for the lack of or impaired reproduction or a disturbance of the biological balance. The aim of every stocking measure is to maintain and promote a species-rich, healthy fish population that is adapted to the size, quality and productivity of the water body and is as close to natural as possible.

The district administrative authority can order or prohibit stocking measures if this is necessary to achieve the conservation objective. The basis for such an order is usually the expert opinion of the district fisheries advisory service.

Which fish may be released without a permit or only with the prior permission of the district administrative authority is determined by § 22 AVBayFiG and, if applicable, the district fishing regulations in the currently valid version.
