A beautiful 3.6m Thresher Shark was bycaught in bass fishing nets 100m off Tintagel yesterday and landed in Newquay Harbour . Sadly occassionally cetacean like harbour porpoise, dolphins,and Seals and in this case Sharks become net entangled and often drown as a result. The target fish was Bass which we can only guess the shark was feeding on as they eat small fish, squid and other small sharks. The commercial fisherman kindly allowed us to record the size of the sharks dorsal fins and tail fin as this is a "BAP" ( Biodiversity Action Plan) species which the government has funded to monitor the health of the species. All sightings or landings of this species are useful to determine the population's health. The shark was landed whole and all of the carcus sold .
