Metadata: FishDAC - 2013 West Scotland Deepwater Trawl Survey
Abstract:
Marine Scotland – Science uses FRV Scotia to undertake a deep-water trawl survey along the continental slope of the Rockall Trough (Neat et al. 2008). This survey area is situated some 100 km to the north and west of Scotland (Figure 1.1). The continental slope separates the shallow shelf seas (< 200 m) from the deep ocean plains (> 2000 m) and supports a diverse assemblage of fish, some of which are commercially exploited such as roundnose grenadier, blue ling, black scabbard, orange roughy and deepwater sharks.

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The main objective of the MS-S deepwater survey is to sample the populations of fish on the slope to enable the generation of indices of abundance, size and diversity which can be compared over time and space. There are secondary objectives such as identification and cataloguing of the mega-benthos and biological sampling for specific research projects. The survey is currently of a fixed-station design stratified by depth at 500, 1000, 1500 and 1750 m. The same stations are sampled each year. The range of depth either side of these strata is ± 100 m. The reason for depth stratification is related to the strong bathymetric patterns in species distributions and abundance. There are some stations at 750 m, but not in all areas because this part of the slope is particularly steep and difficult to trawl. Each ICES rectangle on the slope usually contains one tow in each depth stratum, apart from the 750 m stratum. There are gaps in this sampling strategy notably between 1100 m and 1400 m. However, there is some data to suggest the fish assemblage does not change markedly between such depths. Overall therefore the survey gives good representation of the slope community, although as it stands the lack of randomization prevents estimation of absolute numbers. |
