In Brazil, the main areas are concentrated in the North and Northeast. Despite the introduction of stricter measures of control, such as minimum landing size and closure, as stocks continue to decline, showing that only the regulation of cata crab is insuffi cient to ensure the viability of this species. The data collection underlying this study took place in an island community Beira Mar distant 10 km from the town of Curuçá. Samples were collected monthly from June 2003 to June 2006.

We analyzed 4173 individuals and 2363 females and 1810 males. The breeding season occurs from October to April with peak in March. The size of fi rst gonadal maturation found for width and carapace length were, respectively, of 3.74 cm and 2.4 cm.
