The world’s best beaches….Ballymastocker Beach, Portsalon, yesterdayIT’S already 20C across Donegal – and it’s going to get even warmer on what could be the hottest day of the year today.Forecasters say temperatures could reach 28C this afternoon.The glorious weather is pulling in a huge increase in visitors from across Ireland. And they’re joining an increasing number of foreign tourists who have chosen to come to Donegal this year.Glenveagh National Park – our most visited attraction – has been packed again this week with visitors from throughout Europe, north America, China and Japan.Hotels, B&Bs and restaurants are reporting trade increases of up to 20% on this time last year.“This spell of wonderful weather doesn’t bring in extra tourists from abroad but it does make their visit much more pleasant. Generally however they don’t come to Ireland for the weather,” said a Failte Ireland spokeswoman. “However it does increase staycations and Donegal is seeing the benefits of that.”From trips on the Donegal Bay Waterbus to simply watching dolphins splashing in the warm waters off Malin Head, more and more people are choosing the county to visit – boosting our fastest growing industry.It’s not just tourists who want to come to Donegal.One of the world’s leading car manufacturers is in the county filming a new TV advert.The TV crew in FanadToyota are currently filming an advert for their new Harrier Hybrid and are on location in north Donegal, filming along the Knockalla Coast Road on the Wild Atlantic Way. Enjoy today however; temperatures will return to 20C or 21C this weekend, with rain overnight and into Saturday.ANOTHER SCORCHING DAY FOR DONEGAL AS TOURIST NUMBERS INCREASE was last modified: July 25th, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)Tags:donegalglenveagh national parkPortsalontouristsvisitos
Experimental study on the effect of diet on fatty acid and stable isotope profiles of the squid Lolliguncula brevis
Fatty acid and stable isotope analyses have previously been used to investigate foraging patterns of fish, birds, marine mammals and most recently cephalopod species. To evaluate the application of these methods for dietary studies in squid, it is important to understand the degree to which fatty acid and stable isotope signatures of prey species are reflected in the squids’ tissue. Four groups of Lolliguncula brevis were fed on prey species with distinctly different fatty acid and stable isotope profiles over 30 consecutive days. One group of squid were fed fish for fifteen days, followed by crustaceans for a further fifteen days. A second and third group were fed exclusively on fish or crustaceans for thirty days. And a fourth group was fed on a mixture of fish and crustaceans for thirty days. Analysis of squid tissue showed that, after 10 days of feeding, fatty acid profiles of squid tended to reflect those of their prey. Squid that fed on a single prey type, i.e. fish or crustacean, showed only minor modifications in fatty acid proportions after the initial change and fatty acid profiles were clearly distinguishable between the two feeding groups. Shifts in fatty acid proportions towards respective prey profiles could clearly be observed in squid the diet of which was swapped after 15 days. Clear differences could also be seen in fatty acid profiles of squid feeding on a mixed diet with trends towards either fish or crustacean fatty acid signatures. Stable isotope signatures of squid tissues clearly distinguished between animals feeding on different diets and supported findings from fatty acid analysis, thus indicating both methods to be viable tools in feeding studies on squid species.
