PurposeResearch
Objectives1. Demersal trawling survey of the grounds off the north and west coasts of Scotland and Irish Sea.
2. To obtain temperature and salinity data from surface and seabed at each trawling position.
3. To collect information on the distribution and reproductive development of cod.

Description: CTD deployed prior to the start of each trawling station
Biology and fisheries 
Pelagic fishQuantity: number of hauls = 74
Description: One haul of 30 minutes duration carried out at each station to obtain information on species composition, length frequency and age data where appropriate. Net used was a GOV (BT137) with a small mesh cod-end.
Demersal fishQuantity: number of hauls = 74
Description: One haul of 30 minutes duration carried out at each station to obtain information on species composition, length frequency and age data where appropriate. Net used was a GOV (BT137) with a small mesh cod-end.
CrustaceansQuantity: number of hauls = 74

Other biological/fisheries measurementQuantity: number of hauls = 30
Description: Additional bottom trawls carried out to obtain samples for the cod biological sampling programme (METACOD). Samples of cod collected for length, weight, sex, maturity stage, fecundity and DNA analysis. Cod tagged using acoustic tags and standard flag type tags.
