| Summary: | Magnetization measurements with a superconducting quantum inference device magnetometer of various tissues of the Atlantic salmon ( Salmo salar L.) have shown the presence of magnetic material associated with the lateral line. The data suggest that the material is magnetite and of a size suitable for magnetoreception. Magnetic particles were isolated from the lateral line and nerve tissue, which have characteristics suggesting that the material is magnetite and of biogenic origin. The magnetic particles and their association with the lateral line are discussed in relation to their possible role in allowing the salmon to orientate with respect to the geomagnetic field during the high-seas phase of their migration. |
