| Resumo: |
Some trawlers from Lorient (France) are fishing for Nephrops at the North of 48th parallel. During the last years, the mesh size of their cod-end changed twice. It increased from 45 mm to 60 mm at the end of year 1978 and to 70 mm at the end of year 1979.'. Whereas the change to 60 mm seems to have no immediate- effect on Nephrops landings, the increase from 60 mm to 70 mm results in a loss in Nephrops landings of 30-40 %. That loss in Nephrops landings goes with an increase in some by-catches species as whiting, cod and hake.
Les langoustiniers Lorientais travaillant au nord du 48ème parallèle ont subi successivement deux augmentations de maillage. Ils sont passés du 45 mm au 60 mm en fin d'année 1978 puis au 70 mm en fin d'année 1979. Alors que le passage au 60 mm ne s'est pas fait sentir, le passage de 60 au 70 mm a provoqué une baisse des rendements en langoustine de 30-40 %. Cette baisse des rendements s'est accompagnée d'une augmentation des rendements de certains poissons comme le merlan, la morue et le merlu.
