Due to the large amount of time basking sharks spend at the surface, they are frequently seen in the Bay of Fundy. However, this behaviour of basking at the surface leaves them vulnerable to vessel collisions. It is not uncommon to see a shark bearing scars from an encounter with a vessel. We recently spotted a shark that suffered wounds to its dorsal fin, likely from a vessel’s propeller.
Researchers at the Grand Manan Whale and Seabird Research Station are trying to evaluate the risk of vessel strike to basking sharks in the Bay of Fundy by using information such as the amount of vessel traffic in the Bay and estimating the proportion of time basking sharks spend at the surface, using data from our short-term tags (time-depth recorders).
