“…Deformities have also been observed in P. macrodactylus, an exotic species that has colonised the Gironde estuary for about a decade (Béguer et al, 2007) and which is now found here very frequently. This invasive species is very similar to the native species, P. longirostris, both in its morphology and its ecology, especially its feeding habits (Sitts and Knight, 1979;Sorbe, 1983).…”

“…These studies show alterations in relative growth rates of secondary sexual characters (e.g. presence of appendix masculina, organization of the brood pouch) when the animal is subject to the puberty moult, and these alterations are related to sexual maturity (Mossolin & Bueno, 2003;Béguer et al, 2010).…”

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.

“…The pattern of relative growth varies among different species of the genus. For example it differed between P. macrodactylus and P. longirostris: a break existed in the PW vs CL relationship in non-reproductive females of the latter, with a decay in the growth rate of mature females and the increase in PW during moulting to the reproductive form was constant along the whole size range of mature females (Béguer et al 2010a).…”

SUMMARY: The invasive oriental shrimp Palaemon macrodactylus has been extensively recorded around the world, mainly in estuarine zones. In this study, the life history of this species was studied in Mar del Plata harbour (Argentina), a fully marine area where a stable and dense population has been established. Growth, sex proportion, morphological relationships, size at maturity and reproductive cycle were analysed between March 2007 and March 2009. A total of 9 and 7 modal classes (M1-M9) were detected in the size frequency distributions of females and males, respectively. The modes of both sexes were the same until M4 but from M5 to M7 females were larger than males. The life span was about one year with a clear seasonal growth. Recruitment and reproductive periods were recorded from December to March and October to March, respectively. The total sex ratio was biased to females. Nevertheless, a clear predominance of males was observed in classes smaller than 5.25 mm carapace length (CL). Females reached maturity at a larger size in spring to early summer (October-January) than in late summer (February-March); the estimated sizes for 50% sexual maturity were 6.79 mm and 5.91 mm CL, respectively. The results showed great differences from a presumably native estuarine population (Japan), such as shorter life span, smaller maximum size and smaller size at maturity.Keywords: life history, growth, intraspecific variability, invasive species, Caridea, reproduction. RESUMEN: CaraCterístiCas del CiClo vital del Camarón estuarino invasor Palaemon macrodactylus (Caridea: Palaemonidae) en un ambiente marino (mar del Plata, argentina). -El camarón oriental invasor Palaemon macrodactylus ha sido ampliamente documentado, principalmente en estuarios, alrededor del mundo. En este trabajo el ciclo de vida fue estudiado en el Puerto de Mar del Plata (Argentina), donde se registró una población estable y abundante en un ambiente netamente marino. Entre marzo de 2007 y marzo de 2009 se estudiaron: el crecimiento, la proporción de sexos, relaciones morfológicas, la talla de madurez y el ciclo reproductivo. A partir de las distribuciones de frecuencia de tallas se detectó un total de 7 y 9 clases modales (M1-M9) para machos y hembras respectivamente. Las modas de ambos sexos fueron iguales hasta la M4, mientras que en las M5-M7, las hembras fueron mayores. El tiempo de vida estimado fue de un año, con un crecimiento claramente estacional. El reclutamiento y el período reproductivo fueron registrados entre diciembre y marzo y entre octubre y marzo respectivamente. La relación de sexos fue sesgada hacia las hembras. Sin embargo, en las tallas menores a 5.25 mm de LC los machos fueron mayoría. Las hembras alcanzaron la madurez a una talla mayor en primavera/ inicio del verano (octubre-enero) que en el verano tardío (febrero-marzo). La talla del 50% de madurez estimada para cada período fue 6.79 mm y 5.91 mm de LC respectivamente. Los resultados mostraron grandes diferencias con una población estuarial presumiblemente del sitio de orige...
