|Ship name (ship code)||Genesis (74GI)|
|Cruise period||2010-04-05 — 2010-04-15|
|Port of departure||Peterhead, United Kingdom|
|Port of return||Peterhead, United Kingdom|
1. To undertake a nationally co-ordinated demersal trawling survey of anglerfish species in the northern North Sea.
2. To obtain temperature and depth profiles at each trawling station.
3. To record and map distributions of megrim, four spot megrim and cod.
This trawl 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 standing instructions for demersal trawl surveys.
The cruise track and sampling locations will be delivered to the skipper prior to departure. An approximate map of the sampling area giving the locations of all of the co-ordinated surveys is appended as Figure 1.
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. Daily start times will be at approximately 0800 and continue until approximately 2000. All trawling should be complete by approximately 2300 each night. The Scanmar system will be used to monitor wingspread, door spread and distance covered during each haul. A bottom contact sensor will be mounted on the footrope.
Catches will be worked up according to the protocols for Marine Scotland anglerfish surveys, which are similar in principle to Marine Scotland standing instructions.
A DST will be deployed on the trawl at each station to monitor salinity, depth and temperature.
