Migration patterns and home range of pike‐perch (Sander lucioperca, Linnaeus, 1758) in Dutch river systems

Migration patterns and home range of pike‐perch (Sander lucioperca, Linnaeus, 1758) in Dutch... Pike‐perch (Sander lucioperca L. 1758) is one of the freshwater species caught by professional fishermen in the Netherlands. The species is also popular with sport fishermen. Little is known about its migration and rehabilitation in large river systems. The aim of the present study was to obtain data on the movements of pike‐perch in the Dutch large river systems and investigate when and how far individual fish swim up‐ or downstream. Seasonal migration was expected. The second objective was to gain information on how many fish pass the Haringvlietdam when migrating downstream during high discharge, and ending up in the North Sea. The third objective was to gain data on how many fish were caught by the fishermen. NEDAP TRAIL System® transponders were surgically implanted in 286 pike‐perch between June 2007 and October 2008. Marked fish could be detected via several detection stations in the river systems throughout the Netherlands and one in the River Rhine station in Germany. Sport fishermen were asked to inform the organization when a marked fish was caught. Data collected between June 2007 and April 2010 indicate a pike‐perch home range of 30–40 km, with some individuals migrating up to more than 200 km.

Abstract

Pike‐perch (Sander lucioperca L. 1758) is one of the freshwater species caught by professional fishermen in the Netherlands. The species is also popular with sport fishermen. Little is known about its migration and rehabilitation in large river systems. The aim of the present study was to obtain data on the movements of pike‐perch in the Dutch large river systems and investigate when and how far individual fish swim up‐ or downstream. Seasonal migration was expected. The second objective was to gain information on how many fish pass the Haringvlietdam when migrating downstream during high discharge, and ending up in the North Sea. The third objective was to gain data on how many fish were caught by the fishermen. NEDAP TRAIL System® transponders were surgically implanted in 286 pike‐perch between June 2007 and October 2008. Marked fish could be detected via several detection stations in the river systems throughout the Netherlands and one in the River Rhine station in Germany. Sport fishermen were asked to inform the organization when a marked fish was caught. Data collected between June 2007 and April 2010 indicate a pike‐perch home range of 30–40 km, with some individuals migrating up to more than 200 km. A regional approach regarding fisheries management is necessary. No seasonal patterns were found. Swimming activity was highest during darkness. Results showed pike‐perch around the Haringvlietdam swimming in the saltwater area on the sea side of the dam, and returning to the freshwater Lake Haringvliet, indicating that the structure of the dam is used for feeding, but also that the fish will die if the dam is closed when fish are still outside.
