SEAQUEST LECTURE IN PARTNERSHIP WITH FALMOUTH MARINE CONSERVATION GROUP:
RETURN OF AN APEX PREDATOR TO BRITISH COASTAL WATERS: THE CASE OF ATLANTIC BLUEFIN TUNA (THUNNUS THYNNUS) WITH TOM HORTON
THURSDAY THE 18TH MAY 2017 7.00 - 9.00PM AT FALMOUTH WATERSPORTS CENTRE
Atlantic bluefin tuna (Thunnus thynnus) are large, endothermic predators that range widely in the North Atlantic. Populations have shown long-term variability in abundance and distribution, which has been attributed to over-exploitation, regional oceanography and climate change. Historically, Atlantic bluefin tuna occupied shelf waters off the coast of England, Ireland and Scotland, arriving in the autumn to feed on a variety of lipid-rich pelagic fish. By the early 2000’s Atlantic bluefin tuna had become regionally scarce. Their disappearance was likely symptomatic of the critical state of the eastern breeding stock at the time, which had been fished to record low levels. A recent rise in sightings and recreational and commercial catches suggests that Atlantic bluefin have returned to British coastal waters, and even to regions where they have seldom been seen in the past in any appreciable numbers, including inshore waters of the English Channel and Celtic Sea.
Tom Horton is a research student at the University of Exeter, supervised by Dr Matthew Witt, Dr Lucy Hawkes and Dr Barbara Block. His research focusses on the spatial ecology of Atlantic bluefin tuna, which he has been working on for the past three years off the British Isles. During this talk he will consider these trends in the light of recent stock dynamics and outline the politics behind this enigmatic and highly contentious new visitor.
Cost of talk £3 to pay on the door.
