ObjectivesObjectives

1. To undertake a nationally co-ordinated demersal trawling survey of anglerfish species on the continental shelf and slope to the west of Scotland.

2. To obtain temperature and depth profiles at each trawling station.

3. To record and map distributions of megrim, four spot megrim and cod.

Procedures

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.

Trawling

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.

Hydrography

A DST/minilogger will be deployed on the trawl at each station to monitor salinity and temperature.

Normal contacts will be maintained with the Laboratory.
