1. To increase the knowledge of the offshore and inshore crab stocks to the North of Scotland.
2. To tag Brown Crab, of a range of sizes, from inshore waters to the north of Scotland for investigations of their movements. Tagging will involve using both high-visibility double t-bar tags that are retained on moulting and 'cable-tie' type tags which will be attached to the claws of some of the animals.
3. To biologically sample all tagged crabs for carapace width, shell condition, sex and reproductive state (of females) and record date, time, latitude, longitude, and depth of the return location.
The 3 day charter will be split between 2 vessels to maximise the spread of tagged crabs on the target fishing grounds.
