To undertake a nationally co-ordinated demersal trawling survey of anglerfish on the Rockall Plateau and to the west of the Hebrides.
This is a nationally co-ordinated trawl survey to estimate the abundance and distribution of anglerfish. The survey follows a set of protocols drawn up by an industry/science survey planning group made up of Marine Scotland scientists and fishing representatives. These protocols share much in common with the sampling regimes described in Marine Scotland's standing instructions for demersal trawl surveys.
The survey track and sampling locations (randomly selected) will be delivered to the Captain and Fishing Master prior to departure and giving as much notice as possible. Trawling in Irish waters will take place as necessary.
Fishing operations will take place on a 24 hours basis, with scientific teams split into two teams working 12 hours on, 12 hours off.
One haul of 60 minutes duration will be made at each sampling station; trawling operations will occur in waters up to a maximum of 1000 m. The Scanmar system will be used to monitor trawl parameters such as wing spread, door spread and headline height. A bottom contact sensor will be mounted on the footrope to record touch-down/lift-off at block up/knockout and if the ground gear leaves the seabed during the haul.
Anglerfish and megrim catches will be worked up according to the protocols for this survey. Other target species such as haddock, cod, saithe, skates etc will be sampled as and when available.
Normal contacts will be maintained with the Laboratory and the other vessels (charters) on the survey will be contacted periodically.
