Effects of magnetic fields on fyke net performance

Effects of magnetic fields on fyke net performance Summary The effects of magnetic fields generated by ferritic magnets and mounted in entrances to fyke nets were studied in 1999–2002. With respect to all fish species trapped (perch, pike, roach, rudd, bleak, bream, ruffe) except eel, the catch potential of magnet‐rigged fyke nets was found to be significantly higher (almost 50% on average) when compared with controls. Differences in magnet placement (N or S poles inside the traps) proved to have no significant importance on the number of fish that chose to enter the fyke nets. Specific behavioural mechanisms in adult fish towards magnetic fields as well as application of fishing gear magnet rigging in fisheries practice in inland waters are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

Summary The effects of magnetic fields generated by ferritic magnets and mounted in entrances to fyke nets were studied in 1999–2002. With respect to all fish species trapped (perch, pike, roach, rudd, bleak, bream, ruffe) except eel, the catch potential of magnet‐rigged fyke nets was found to be significantly higher (almost 50% on average) when compared with controls. Differences in magnet placement (N or S poles inside the traps) proved to have no significant importance on the number of fish that chose to enter the fyke nets. Specific behavioural mechanisms in adult fish towards magnetic fields as well as application of fishing gear magnet rigging in fisheries practice in inland waters are discussed.
