Cruise summary report
|Ship name (ship code)||RV Corystes (74RY)|
|Cruise period||1995-12-06 — 1995-12-21|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
|Objectives||1. To release 50-100 plaice equipped with electronic data storage tags, and similar numbers of control fish tagged with Petersen tags. The aim was postponed due to a lack of plaice.
2. To track migrating plaice equipped with long-life transponding acoustic tags and to estimate their swimming speed and orientation by simultaneous use of the sector scanning sonar and acoustic Doppler current profiler (ADCP).
3. To track plaice equipped with attitude sensing acoustic transponding telemetry tags in order to assess how much of the time plaice spend swimming horizontally when in mid-water. This information is needed for the compass tag development programme. This tag was not available for the cruise.
4. To test methods of releasing acoustically tagged cod at sea from new "beehive" cages prior to undertaking a cod tracking programme as part of MF0130.
