Grimsing is a classical Danube area with an extent of 80 ha, 5,2 km in length, about 28 ha of it being back water area and 52 ha free flowing water with ample structuring and excellent fish stock. The area begins at the bridge across the Danube below Melk and ends near Aggsbach – Markt (marked by respective boards). For the time being, the area of Aggsbach left-hand bank is added to this area for co-management until further notice. The number of fish corresponds to the Danube fish stock with carps and pikes being maintained by stocking.

As far as possible, only wild carps are being stocked, up to a maximum of 2-sö – (2 summers` age). The reproduction of pike perches in this area is still satisfactory and therefore the latter need no stocking! The number of licenses granted is strictly limited. Guest day licenses for members are available from June 1st to October 31st. From October 15th especially tough guys are able to obtain a day license for Danube salmons valid for all Danube areas, fishing in back water, however, excepted.

It is compulsory to have an official fishing- or guest license for the federal province of Lower Austria.
