New evidence is indicating that wild salmon are adapting to climate change by feeding in colder waters, The Irish Times reports.
According to salmon expert Dr Ken Whelan, wild salmon are now diving as far as 800m below the surface - normally the preserve of the sperm whale - to feed for periods of up to 24 hours during winter months.
They are also travelling closer to the polar ice fields, in response to the warming of the Atlantic Ocean.
The change in behaviour was noted at a salmon summit in France attended by more than 100 fishery managers and scientists from across Europe, which was convened to discuss the threat of climate change to wild salmon stocks at sea.
Plankton levels are particularly affected by the changing wind and ocean currents, said Dr Whelan of findings from the EU-funded Salsea programme, which he led.
“Surviving the first winter at sea seems to be the key challenge for these stocks, and the salmon in the northern states like Norway and Russia, seems to be less affected,” he said.
But the recent return of wild salmon to the Tolka in Dublin, as well as healthy returns along other inland waterways, highlighted that the news was not all doom and gloom.

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
