What is „Fish Trek“?
As long ago as 1932, Koch determined “that a high finder´s reward results in a reward of returned tags.” To maximize the knowledge rewards of Fish Trek, we offer a reward of 20 € for return of an individually marked fish or its tag, when all information is included on the location and date when it was found.
