Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name FRV Scotia (748S) cruise 0505S
Short name 0505S
Objectives and Narrative 1. Monkfish trawl trials (K Peach)
Establish procedures for Fishing gear BT 185 monkfish trawl with 2,000 kg Mogere doors.
Fishing operations will be divided into daylight and dark periods.

2. Daylight Fishing
Observations on the net will be made using RCTV.
Fixed cameras and lights will be attached to the wings of the trawl and Scanmar sensors deployed on net and doors. Data from Scanmar sensors will be recorded for all tows.
Daylight observation hauls will be made using standard cod-end rig.
The fishing target during the first half of the cruise is to achieve a minimum of 12-15 hauls. These will all be carried out in daylight hours to allow net mounted cameras and RCTV observations to be made. The RCTV will be deployed in the most optimal light conditions. Tows will be of 1 hour duration.
Fishing will be conducted in an area called 'The Shoal' within the closed cod box to the East of Rona approx. position 59N 5W. Exact positions for a six-mile tow on clear ground at 130 metres

3. Observations on cetacean and other biological traces were made throughout the cruise as oppurtunities arose using a towed streamer array; drop keel mounted hydrophones and by deployment of radio sonar buoys in more confined areas

4. Data was collected from the ship's Thermosalinograph system throughout the cruise to establish water flow rates

5. A minilogger attched to the BT185 collected information on bottom temperature throughout each tow and CTD information was collected at each release position during tagging operations

A half landing and gear/personnel changeover took place in Aberdeen on the 12/04/2005

Physical oceanography  
CTD stations Quantity: number of stations = 5
Description:  
Biology and fisheries  
Gear research Quantity: number of hauls = 15
Description: Monkfish trawl trials for observation and gear geometry purposes throughout the cruise. Scanmar data were collected for a number of tows for engineering studies  
Gear research Quantity: number of deployments = 17
Description: Multisampler frame on the methot net wire or attached to the PT 160 trawl. Observations were made using cameras  
Mammals and reptiles Quantity: number of deployments = 5
Description: Buoys deployed in the Scalloway Deeps area spread over 4 days. 240 minutes of sonar buoy recording time was made.  
Mammals and reptiles Quantity: activity duration in hours = 170
Description: Drop keel-mounted hydrophones used for cetacean monitoring throughout most of the cruise  
Mammals and reptiles Quantity: activity duration in hours = 30
Description: Passive acoustic monitoring of cetaceans using towed hydrophone array  
Taggings Quantity: number of hauls = 15
Description: Tows for live fish tagging over 4 nights using a modified cod-end attached to the BT185. Fish were tagged using Data Storage Tags or T-bar tags. Fin clips were taken from all DST tagged fish for genetic analysis. 165 Haddock, 3 Cod, 25 Whiting and 6 Monkfish were tagged.
