| The reproductive biology of Aegla caslro Schmitt, 1942 from Buraco do Padre, Ponta Grossa, Paraná State, was analyzed. The sampling was done monthly, from February/97 to January/98 with aid of hand net and screens at three stations, under an effort of 120 minutes. The mean air temperature ranged from 15.0ºC (May, July, September and October) to 24.3ºC (December and January), and the water temperature from 15.8ºC (July) to 22.3ºC (December). The dissolved oxygen oscillated from 95.7% (March) to 100.2% saturation (August) and the pH from 6.1 (July) to 7.2 (September). A total of 827 specimens were obtained among which 384 males, 311 females and 132 juveniles. Males predominated over females, but the sex ratio followed the standard model of 1:1. Juveniles... |

| Relative growth of the male major chela and female abdome was studied in a population of the fiddler crab Uca leptodactyla Rathbun, 1898 from Itapoá, Santa Catarina coast, southern Brazil. Major chela length (CMQ) was measured from 191 males, and abdomen width (LAB) from 128 females. Carapace width (LC) was the reference dimension for both sexes, which ranged from 3.9 to 11.5 mm for males, and from 3.15 to 10.65 mm for females. Males grew bigger than females. Relationship between CMQ and LC showed a transition point at 8.35 mm LC in males, and between LA and LC at 7.10 mm LC in females. Growth was allometrically positive in the early ontogenesis and isometric after the puberal molting for both sexes. Regressions between LC and CMQ in males read as: logCMQ... |

| A study of the annual abundance fluctuation, temporal distribution and size composition of Aegla castro Schmitt, 1942 was carried out at the Buraco do Padre, Quebra-Perna River, Tibagi River Basin, in the municipality of Ponta Grossa, Paraná State. The samplings were done monthly, from February/97 to January/98 with the aid of a hand net and screens at three stations, under an effort of 120 minutes. The average air temperature ranged from 15.0ºC (May, July, September and October) to 24.3ºC (December and January), and the water temperature from 15.8ºC (July) to 22.3ºC (December). The dissolved oxygen oscillated from 95.7% (March) to 100. 2% (August) saturation, and the pH from 6.1 (July) to 7.2 (September). The water flow speed varied from 0.2 m/s to 1.2... |
