A new BBC Radio Ulster programme starting on Sunday, September 14 at 1.05pm explores how rising sea temperatures are affecting marine life around Irish shores and the impact on the fish we eat.
Presenter Jenny Witt travels around the north coast of Ireland to meet experts, trawler men and traders to discuss the knock on effect warmer waters will have on consumers and the fishing industry.
In this half-hour programme David Reid, a senior marine scientist, explains that cold-water fish, like cod, are moving further north and warm-water fish like blue fin tuna are migrating to Irish waters.
Trawler men from Killybegs in County Donegal also reveal that boarfish is the current catch of the day and Jenny visits Saint George’s Market in Belfast to find out if customers are willing to adapt their eating habits.
Rising sea temperatures have caused Pacific oysters to spawn all year round in Lough Foyle – one of the first areas in the UK where this has happened - and Jenny talks to shellfish producers about measures they are taking to protect their oyster stocks from disease.
Jenny says: ““It’s been amazing to see how a relatively small rise in sea temperatures is affecting the creatures in our waters. Leatherback turtles and blue-fin tuna are moving in, and other species like cod and mackerel are moving north. It’s happening slowly but surely.”Sea Change airs on Sunday, September 14 at 1.05pm on BBC Radio Ulster. 92–95FM & DAB digital radio, digital TV and online at bbc.co.uk/radioulster
