This dataset includes all the CHALIST surveys between 1983 and 1992, that is five surveys undertaken in 1983, 1985, 1986, 1987 and 1992. The aim of CHALIST surveys was to evalute the demersal resources of the Gulf of Lion in order to monitor annual variations of the main commercial species in terme of spatial distribution, average weight and size and age compositions and abundance indices.
