Graham Johnston

Graham Johnston is a fisheries scientist at the Marine Institute in Ireland, known for his research on marine species and the effects of climate change on fish populations. His work includes analyzing trends in fish distribution and abundance, particularly in relation to changing sea temperatures and ecosystem dynamics. Johnston has observed the increasing presence of species like Atlantic bluefin tuna and various newcomers such as grey triggerfish in Irish waters, attributing these changes to a complex interplay of climate factors and marine biology.
