Of course, everyone thinks first of sturgeon, salmon, sea trout and eel, but other species of fish also migrate through the rivers, provided they are not impassably obstructed, although not over such great distances as the first three species mentioned. This conference is dedicated to all of them, with a focus on anglers and fishermen, but also on water engineers, scientists, nature conservationists, farmers and public authorities.
In addition to hydraulic engineering maintenance measures in accordance with the EU Water Framework Directive, it is important to ensure the passability of rivers, unless the aim is to protect native aquatic species such as the noble crayfish from invasive species such as the American crayfish. On the eve of the International Migratory Fish Species Day (15.05.2020), this conference is therefore also aimed at the interested public in order to promote the passability and cleanliness of German rivers.
The Brandenburg Academy “Schloss Criewen” is a suitable location for this, as it is situated directly on the Oder, which, apart from two small weirs in Silesia, is still fairly continuous and unobstructed with its tributaries. Re-introduction projects for sturgeon are the logical consequence of this. Contributions are needed that help to understand the way of life of migratory fish species and to offer them assistance in environments that have been heavily altered by humans.
