Última Etude d'une gestion optimale des pecheries de langoustine et de poissons demerseaux en Mer Celtique. Tome 1 ArchiMer Charuau, Anatole; Biseau, Alain. The entire study is divised into three parts : Phase 1 - Collection of data and description of fisheries. Phase 2 - Diagnosis on the exploitation level for the main species. Phase 3 - Fleets analysis and simulation of the exploitation of the fishery. In addition to the description of the fisheries, in the first part, a very cheap method for the study of discards is described for all species and all fleets, the purpose being to use length cohorts analysis according to the JONES'method (1981). Preliminary works on monks, megrim and cuckoo ray are also presented. Tipo: Text Palavras-chave: Discard; Fleet; Demersal species; Celtic Sea; Rejet; Flottille; Espèce démersale; Mer Celtique.

Tome 2 ArchiMer Charuau, Anatole; Biseau, Alain. The theory of the evaluation of discards applied in phase 1 to the main eight species is described. Then, for each one, the biological parameters are calculated and diagnosis based on length cohorts analysis JONES (1981) are proposed The gadoids, whiting and cod, are heavily exploited and the catches are always recruitment dependant. The bottom species (monks, megrim, rays and Nephrops) are fully exploited or lightlhy over - exploited. Using the fisheries statistics of the data basis about the Celtic Sea, a first classification of fleets is proposed with the individual fishing powers.
