| Objectives and Narrative |
Objectives
1. To conduct an acoustic survey to estimate the abundance and distribution of herring in the north western North Sea and north of Scotland between 58°30'-62°N and from the shelf edge to 2°E, excluding Faroese waters. 2. To obtain biological samples for echosounder trace identification using a pelagic trawl. 3. To obtain samples of herring for biological analysis, including age, length, weight, sex, maturity and ichthyophonus infection. 4. To obtain hydrographic data for comparison with the horizontal and vertical distribution of herring. Narrative Scotia departed Aberdeen at 0900 on 30 June and made passage for Scapa Flow, Orkney Islands, to commence calibration of acoustic systems. Two trial deployments of fishing gear took place en route to familiarize crew with fishing gear and to set up the new netsonde systems onboard. Scanmar distance units were used to confirm that the addition of dropper chains to the footrope of the gear had no significant effect on the net geometry. Calibration took place between 0030 and 0800 on 1 July. The survey commenced at 1200. Numerous fish traces were seen throughout the South Eastern area in particular and fishing took place as appropriate. Fishing was generally successful throughout the first half of the survey and herring were caught in all hauls. Poor weather on 7 July restricted the vessel speed and precluded fishing operations for 24 hours. (The netsonde cable having parted due to the swell height when fishing had been attempted). In order to avoid the poor weather an attempt was made at a second calibration of acoustic systems in the evening of 8 July in Hope Wick at the South end of Bressay. Unfortunately, there was insufficient shelter from the 40 knot winds and the calibration was abandoned in the early hours of 9 July. Scotia made her way into Lerwick at 0900 on 9 July for her 24 hour half landing and to change scientific and compliance staff. R Catarino also joined the vessel during this period. Scotia departed Lerwick at 0900 on 10 July and was able to recommence surveying as the weather had greatly improved. Scotia's planned survey track had to be reduced in the Northern part of the survey area to compensate for the time lost to weather. However, transects undertaken by the accompanying charter vessel ensured that sampling densities still met the required minimum for the survey in this area. As in previous surveys, few fish traces were seen through the Northern area. Few traces were seen on the western side of the survey area and these were fished where tidal conditions and seabed topography allowed. |
