Resumo: | A recreational fishery that use ghost-shrimp as bait was evaluated along 11 km of a sandy beach of Paraná State. The beach was divided in five sectors and samples were obtained along a transect extended on the middle of each sector, after and before months of major extractive activity. The highest densities were found in beaches with well select very fine sands and gentle slope. The density decreased only at the sector that presented greater extractive activity. In this sector, the smallest mean modal size was detected too. The total standing stock of the whole area was 2,486,250 individuals before summer's months, with a mean density of de 4.48 ind.m-2. Annual fishing effort represented nearly 10 % of total standing stock.
