Abstract By‐catch is estimated by sampling the whole fishery (February to April 1987) on the basis of a survey of the fishing effort: 16 species of commercial interest are considered, among them 3 species are dominant: Flounder, sprat and brown shrimp (98,4% of the 49,3 million individuals). By‐catch consists mainly of very young animals (larval or 0‐group stages). An attempt is made to consider the ratio between by‐catch and the potential natural mortality of juveniles.
