Global fisheries leaders are gathering for a major conference on the future of sustainable fishing.
Among the attendees at the World Fisheries Congress in Edinburgh will be Prince Charles. The Prince, known as The Duke of Rothesay in Scotland, will speak in his role as the founder of The Prince's International Sustainability Unit.
The Tuesday event is expected to attract some 1,000 delegates from more than 65 countries, with 22 keynote speakers from industry, science, fishing, and aquaculture.
Among those taking part will be Scottish Environment Secretary Richard Lochhead and UK fisheries minister Richard Benyon.
Mr Lochhead said: "I am delighted to welcome the World Fisheries Congress to Edinburgh this week. As one of the foremost fishing nations, Scotland is at the centre of international efforts to sustain the world's fisheries.
“Bringing together leading scientists and experts will provide stimulating and thought provoking discussions, and I look forward to building on our work and exchanging ideas with international partners."
He added that fishing made a "massive contribution" to Scotland's economy and stressed: "The Scottish Government is committed to doing all we can to preserve the marine environment and to ensure a sustainable, long-term future for the fishing industry in Scotland."
The event is organised by the World Councils of Fisheries Society, whose president Professor Felicity Huntingford, said: "The 6th World Fisheries Congress is a truly global event that brings together scientists from all discipline areas that cross the freshwater and marine boundaries."
She added: "This year's Congress will investigate the significant role that science plays as the foundation stone to good management and sustainable fisheries, including the increasing importance of aquaculture in the provision of food and nutrition.
“The overarching aim of the conference is to exchange information and promote discussion of complex and controversial issues, so that knowledge can be shared with a wider audience, and common solutions identified."
