Description
Study of the dispersion and dispersal mechanisms of pelagic key species on the Belgian Continental Shelf (BCS). The focus of the dataset is on those species that have a pelagic life-style or have pelagic larvae, mainly clupeidae. The Belgian coastal waters are internationally very important areas for a number of sea and coastal birds. Studying the distribution patterns of the possible food sources (i.c. Pelagic fish) of these birds will lead to a better understanding of their spatial distribution patterns. Sampling is done with the Zeeleeuw R.V. Underway data is registrated in MIDAS. more

Between January 2003 and February 2004 samples were taken on a monthly basis at eight different station in the Belgian Continental Shelf. The pelagic fish samples were taken using a MIK-net (Midwater Isaac's Kidd trawl) with a mesh size of 3 by 3 mm. At each station trawling took place above the bottom and below the water surface and a number of environmental parameters were recorded (turbidity, salinity en temperature) using a CTD-scan (SBE 19plus). All fish identified to species, counted, measured and densities were calculated. For dominant species, focus was on spatial and temporal variation as well as size distribution.
