Extremely exposed. Stock reared in bags on long-lines.
Key to spatfall groups
Algae recruited all year round. Hydroids recruited all year
other than December, serpulids and tube-forming amphipods recruited all year.
Barnacles recruited in April, May and August, blue mussels in August, ascidians
in June and July.
tube-forming amphipods and polychaetes
Enteromorpha sp. and other algae
serpulids Pomatoceros sp.
barnacles Balanus perforatus
Changes in Wet Weight
The fouling weight increased until October 2005, with a rapid decrease afterwards.
Until June 2006 there was a slight increase followed by another decrease and
rather erratic from that date. Accumulated weight was highest in spring and summer,
lowest in autumn.
Video shows developed fouling community on long-term panels deployed 2 m below the surface at Sagres.
This EU funded Collective Research project with 23 partners from Norway, Ireland, UK, the Netherlands, Belgium, Spain and Portugal, will provide the European marine aquaculture industry with low cost practical solutions to control biofouling.
