Three towed satellite tags have been deployed on basking sharks in the Inner Hebrides. Tags were deployed in Gunna Sound, between the islands of Coll and Tiree. These tags will provide further insight into the movement patterns of these large plankton-eating sharks through the summer surface foraging period. In late autumn the sharks will move away from the surface and the tags will stop transmitting as they can only operate at the sea surface. As in previous years, we then hope to hear from the sharks in early Spring and potentially from areas far south of Scotland, including Spain, Portugal and France.
