ILVO epifauna and demersal fish data: epifauna and demersal fish monitoring on the Belgian Part of the North Sea since 1979 [ILVO epifauna en demersale visdata: epifauna en demersale vismonitoring op het Belgisch deel van de Noordzee sinds 1979] Citation Availability: Restricted The data are withheld from general circulation and disclosure but access may be obtained on a case-by-case basis through negotiation Notes: Data is available through the EMODnet Biology portal: see child datasets below in this record. Description Density, species richness and diversity of epifauna and demersal fish is being monitored on the Belgian Part of the North Sea since 1979. more The epibenthos and the demersal fish is sampled on a number of stations spread over the Belgian Continental Shelf. Sampling is done using a 8m beam trawl and a finemeshed shrimpnet during a half hour trawl, traveling at 3.5 knots. The use of this type of net brings less harm to the sediment ecosystem then the use of chainmatts, while it is still efficient in sampling epibenthic organisms and most of the demersal fish species. Only the organisms that attach to the bottom like, sole, semi-pelagic species like herring, thin fish species like sand eel are caught less efficient. The material is immediately sorted, with or without the use of a sorting machine and is identified, counted and measured on board and/or in the lab.
