Annual fluetuation of densities and population strueture of Armases angustipes (Dana, 1852) from a rocky shore at Farol Island, Matinhos, Paraná, Brazil (25º51'S and 48º32'W) were studied. The population strueture was treated in the following aspects: sexual proportion, dial intensity of activities, size composition and its fluetuation, and general condition of the crabs. The collections were made monthly, from January to December 1991. The samples were obtained handly, in the morning and at night, at the supratidal zone during low tides. There were caught 1,139 crabs, among which 34 were juveniles, 544 males, 555 females and 4 ovigerous females. Population density was highest in April (19.56 ind.m"² ) and in October (23.86 ind.m"² ). The sexual proportion... |
