The methods of quantifying fishing activity in the coastal lagoons of Languedoc using three indicators (number of fishing nets, boats and fishermen) are presented and compared. In practice, aerial counts of fishing nets is the only method which can be used on a regional scale; errors are variable but never exceed 10%. Although counts by indirect observations (photo-video) are more precise, they are still too expensive to be applied to routine surveys. the visualization of the nets is improved by optical filters (with black and white infra-redfilms). For smaller lagoons, it is cheaper to count fishermen, but the relationship between this indicator and the number of nets is not constant.(Résumé d'auteur)
