%X juvenile snails of limicolaria flammea (m¨¹ller) of approximately two months old, with 1,20 ¡À 0,02 g average live weight and 15,37 ¡À 2,34 mm average shell length were subjected four densities (100, 200, 300 and 400 snails/m2) during 12 months in order to determine their effect on growth and reproduction. the best biological performances were obtained with the density of 100 snails/m2 which induced high food intake (0,14 ¡À 0,002 g/day/g of live weight), better growth and low mortality (16%). this density induced high number of laid eggs, high number of eggs per laying and a high percentage of hatching (70,33%) after a relatively short duration of incubation (12 ¡À 1,8 days). at a density of 400 snails/m2, snails nourished themselves little (0,005 ¡À 0,002 g/day/g of live weight), reproduced slightly and had 60% of mortality.
