Study of epibenthos and demersal fish in and around the dredging areas of the Belgian Continental Shelf (1977-1981) Citable as data publication Maertens D.; Rijksstation voor Zeevisserij; Centrum voor Landbouwkundig Onderzoek (CLO): Belgium; (2016): Study of epibenthos and demersal fish in and around the dredging areas of the Belgian Continental Shelf (1977-1981). https://doi.org/10.14284/192 Contact: Availability:  This dataset is licensed under a Creative Commons Attribution 4.0 International License.Description Presence, density and biomass data for ichtyofauna and epibenthos sampled in and around the dredging areas between 1977 and 1981. The data were digitized by VLIZ from the original report: Maertens, D. (1984). Analyse van de levensgemeenschappen op het Belgisch Kontinentaal Plat: studie van de epibenthale biocoenoses en van de demersale Pisces in en rondom de baggerzones. Mededelingen van het Rijksstation voor Zeevisserij (CLO Gent), 201. CLO Gent: Gent. 45, + annexes pp. more The first part of the dataset contains a list of all epibenthos and fish species caught in and around the dredging areas between 1977 and 1981. Next seven sampling points (BV1-BV7) were choosen in the dredging areas and divided in 2 zones (Zone I and Zone II). Per sampling point and sampling date or period abiotic factors and some exceptional catch data are given. Per zone and per year (1977-1981) average density, biomass, diversity, dominance and association indices for epibenthos and fish is calculated. Eventually density of autumn samplings for most important groups of epibenthos and fish is given.
