Cruise summary report
|Ship name (ship code)||FRV Scotia (748S)|
|Cruise period||2002-06-05 — 2002-06-22|
|Port of departure||Aberdeen, United Kingdom|
|Port of return||Aberdeen, United Kingdom|
|Objectives||1) To obtain estimates of distribution and abundance of Nephrops in the Fladen Ground, Firth of Clyde, North Minch, South Minch and Stanton Banks using underwater television. If time permits, the survey will also include stations in the Sound of Jura and Noup.
2) To make use of the TV survey to estimate the densities of other shellfish species and benthic organisms and to record evidence of trawling activitiy.
3) To collect samples of the sediment at each TV station.
4) To carry out Nephrops trawling in each stratum throughout the survey areas for size and sex composition analysis and examination of biological features.
5) To collect samples of Nephrops for comparison of reproductive condition and morphometrics in different areas.
6) To collect samples of Arctica islandica for studies of shell chemistry and age.
Underwater TV survey of Nephrops grounds at the Fladen, North Minch, South Minch, Firth of Clyde, Sound of Jura and Stanton Banks, for fishery independent stock assessment. Sediment collected at each station. Some trawling also carried out.
