Since 30 July we're on our way on the annual beam trawl survey, one of the important sources of information for stock assessment of flatfish species (plaice, sole, dab, brill, turbot). As the sampling grid is the same over years, we can compare the results of the timeseries. This is the first update of the 2018 beam trawl survey.
voortgang tot 23 augustus//progress till 23 August, 15:00 GMT |
As you can see, we've covered the southeastern part (black dots, 82 stations) nicely thanks to everyone on board, nice weather and no severe gear damages or other misfortune. In that area, we caught 47 fish species and 70 other species (crabs, starfish, etc.). The most frequently caught finfish species were Pleuronectes platessa (plaice, 82 stations), Buglossidium luteum, Callionymus lyra, Limanda limanda (solenette, common dragonet, dab; all at 80 stations) and Arnoglossus laterna (scaldfish; 79 stations). Of the other species, we caught Asterias rubens, Liocarcinus holsatus, (both at 80 stations), Pagurus bernhardus (75), Cancer pagurus and Corystes cassivelaunus (at 63 stations).
