Time flies and the Irish Anglerfish and Megrim Survey (IAMS) Leg 1 survey on board the RV Celtic Explorer for TTRS has come to its finish! After these intense days engaged on board, we´re now turning again to our day by day routine on land, though the boat´s movement will accompany us for just a few days. These have been days of intense private and group work, the place now we have developed totally different expertise that positively will assist us in our profession as marine researchers.

All through these 8 days offshore, we found the usual strategies acknowledged by ICES to gather and measure all of the samples caught by the underside trawl. Actually, the quantity of fish that may be trapped in such a brief time period is fairly spectacular, so we tried our greatest to be taught the process shortly to be as supportive as doable for our groups.

Early within the first steps, we received fascinated by the nice number of demersal species that may develop such unbelievable vary of shapes and swimming strategic options. For certain, their real traits may be important in serving to them to outlive in such innermost locations.

As soon as the fish have been sorted by species, we proceeded to take totally different measurements, akin to size and weigh, in addition to intercourse and maturity when wanted. Additionally, otoliths had been collected for sure goal species. These calcareous constructions situated within the interior ear will present beneficial insights into the age of the people due to the concentric rings which are yearly fashioned. It took us a while to get conversant in the totally different species (nonetheless studying some names) and specifically to get the right method to extract the otoliths, as a few of them will be actually tough. Nonetheless, you actually save a outstanding period of time when taking the info, due to the measuring board of bar codes.

Moreover, some specimens of sharks and rays had been launched after being measured and tagged. We actually hope they’ve recovered effectively!

The services onboard are merely superb. The rooms are very snug, simply as a lot because the longue space, the place you possibly can simply calm down and luxuriate in your free time along with your colleagues.

Due to Captain Dennis Rowan and the remainder of the RV Celtic Explorer crew. Many due to the Chief Scientist on board Eoghan Kelly and Sara Jane Moore and the remainder of the scientists, who kindly provided us their assist and who made us a part of the staff because the starting of the survey. We additionally actually respect the work of John Boyd and the Strategic Marine Alliance for Analysis and Coaching, for giving us the chance to take part on the survey.
