| In the time period between May/92 to April/93, 2693 (1243 males and 1450 females) specimens of Penaeus paulensis Pérez Farfante, 1967 were collected. The shrimps were captured by night using a hand net in äreas between 30 to 150 cm deep. The abundance of P. paulensis is regulated mainly by the temperature, the summer being the season of greater profusion. The major recruiting period takes place in the Spring with shrimps measuring between 1,0 to 3,0 cm and approximately 2,0 months old. The population reaches the pre-adult in the Fall-Winter period with average length between 8,8 cm (females) and 9,3 cm (males). The migration to the ocean occurs during the Winter. The artisanal fishing in the Conceição Lake is predatory, acting upon the young and pre-adult... |

| In the time period between May/92 to Abril/93, 602 (267 males and 335 females) specimens oi P. brasiliensis Latreille, 1817 were collected. The shrimps were captured by night using a hand net in áreas between 30 to 150 cm deep. The amplitude of length ranged from 1,3 to 13,7 cm, the highest frequencies of capture were registered during the Fali between the classes of 7,0 and 10,0 cm. The males present isometric growth and the females negative allometric one. The size of the pre-adult ranged from 8,8 cm for the females and 9,2 cm for the males. The recruiting occurs chiefly in the Summer with intense growth during the Fall-Winter period, reaching a climax with the migration of pre-adults to the ocean in midwinter. |
