ABSTRACT The carapace length (CL) at the onset of morphological sexual maturity (MSM) in Aegla paranaSchmitt, 1942was estimated in a population located at Negro River Sub-basin, Upper Iguaçu Basin, southern Brazil. The animals were captured with Surber net and with baited traps in Negro River and in its tributary Totó River, in December/2017, June and July/2018. Carapace length of each individual was measured from the tip of the rostrum to the posterior margin of the carapace, with a digital caliper or under a digital microscope. Length of the major cheliped propodus (LMAP) of males and width of the abdomen (LA) of females were measured for relative growth analysis. The CL at the onset of MSM was estimated as the inflection points on the scatter plots with... |

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... |

Studies on the growth of the blue crab C. danae were carried out by the analysis of size-frequency distributions, and the growth curves were determined for both sexes through Bertalanffy equation. 613 males and 511 females were obtained from 10 collecting sites of the lagoon, at night, monthly from January/88 to July/89. The growth curves in carapace width were described according to the following equations: Wid∞ = 14.0 (1-e-0,6975.t) for males and Wid∞ = 13.3 (1-e-0,6555.t) for females. The growth curves in body weigth were also determined, based on the equations of the growth curves and the relationship between body weight and carapace width. The equations are:Wt = 156.9 (1-e-0,6975.t)2.9153 for males, Wt = 134.0(1-e-0.6555.t)2.8994 for females. |
