“…Indeed, the body size of the smallest female carrying eggs observed during this study was 9.7 mm CL. This value is similar to that reported by Anger and Moreira (1998). Overall, uncertainty in size at maturity might have important implications for fisheries stock assessment (J. Anderson and J.…”

Abstract. Macrobrachium acanthurus inhabits estuaries and rivers in the western Atlantic. It is not clear whether females migrate towards estuaries to hatch larvae, as reported for other congeneric shrimps. We tested whether females of M. acanthurus exhibit reproductive migrations. The population dynamics of this shrimp was studied in the Ribeira de Iguape River, Brazil. Four sites that differ in position with respect to the coast were sampled monthly during 2007. In M. acanthurus, reproduction was seasonal and reproductive intensity did not vary among study sites. Females brooding early and late embryos were found at all study sites during the reproductive season. No disappearance of reproductive females was observed at the study site located furthest away (,150 km) from the coast. Thus, reproductive females of M. acanthurus do not exhibit reproductive migrations towards estuaries to hatch larvae. Maturity in females was reached at smaller body sizes during the austral summer and spring compared with winter and autumn. Growth rate and body size was sex-specific; males grew slower but attained larger average and final body sizes than females. This information needs to be considered in assessing stocks and establishing sustainable management plans for M. acanthurus in Brazil.

“…In individuals with the same TL, carapace of females tends to be greater than that of males, as previously noted for other Palaemonidae Palaemon northropi, P. pandaliformis, Macrobrachium acanthurus (Wiegmann, 1836) and M. olfersi (Anger & Moreira, 1998). Bauer (2004) suggests that as males of many species of this family do not protect or defend the reproductive females or their territory, a larger size would not be necessary.…”

“…Images were analysed with ImageJ software version 1.45 (Rasband, 2006). Adopted scaling was proposed by Anger & Moreira (1998): carapace length (CL), total length (TL), abdomen length (AL), and pleura length (PL) (Fig. 1).…”

ABSTRACT. This study comprises the description of relative growth and sexual maturity of a population of Palaemon pandaliformis Stimpson, 1871 in Salsa River (Northeastern Brazil). Samples were collected monthly between September 2009 and August 2010. Females were larger, heavier, and showed a greater allometric coefficient (b) than male specimens. Only carapace length vs. pleura length in females presented a significant difference in the relative growth pattern, indicating a puberty moult. This relationship is strictly correlated to reproduction and its success rate in female shrimps. Estimated carapace length in 50% of mature females (CL 50 ) was 4.53 mm. It was not possible to compare obtained CL 50 results due to a lack of studies on this species. Comparison was based on the size of the smallest captured ovigerous female (3.81 CL mm), which is within the scope of recorded size for estuaries located in higher latitudes. This study reveals the lack of research on this genre in freshwater environments on a national and global scale. KEYWORDS.Caridea, allometric growth, morphometric relationships. RESUMO.Crescimento relativo e maturidade sexual de Palaemon pandaliformis (Crustacea, Palaemonidae) no Nordeste do Brasil (Canavieiras, Bahia). Foram descritos o crescimento relativo e a maturidade sexual de uma população de Palaemon pandaliformis Stimpson, 1871 do rio Salsa (Nordeste do Brasil). As coletas foram realizadas mensalmente entre setembro de 2009 e agosto de 2010. As fêmeas foram maiores, mais pesadas e exibiram um coeficiente alométrico (b) maior que os machos. Apenas a relação comprimento de carapaça vs. comprimento de pleura nas fêmeas, apresentou uma diferença significativa no padrão de crescimento relativo, evidenciando a muda da puberdade. Esta relação é estritamente correlacionada aos eventos reprodutivos e ao sucesso deste em fêmeas de carídeos. O comprimento da carapaça em que 50% das fêmeas estão maduras (CL 50 ) foi estimado em 4,53 mm. Não foi possível comparar os resultados de CL 50 obtidos devido à falta de estudos enfocando a espécie. A comparação foi feita através do tamanho da menor fêmea ovígera capturada (3,81 CL mm), o qual está dentro da amplitude de tamanho registrada para estuários localizados em latitudes mais elevadas. Este trabalho aponta a falta de estudos para este gênero em ambientes dulceaquícolas, uma vez que estes são raros, mesmo em escala nacional e global. PALAVRAS-CHAVE.Caridea, crescimento alométrico, relações morfométricas.

“…BilGin & Samsun (2006: see table 7, for review) and Janas & Mańkucka (2010: see table 3, for review) compared increases in the change of egg diameter of marine Palaemonids and found the same pattern recorded in this study. AnDerson (1982) states that an increase of the long axis is caused by growth of embryonic structures in the cephalic-caudal axis. Nazari et al (2003) suggest that during the final stage of incubation, the growth of egg axes is an important characteristic in embryogenesis since it enables greater mobility to the embryos and larvae hatching.…”
