This study evaluated the influence of the water and air temperatures, pluviosity and photoperiod on the breeding season of Goniopsis cruentata (Latreille, 1803), in Ubatuba littoral, southeastern Brazilian coast. Monthly collections were conducted out from January/95 to December/96 in an estuarine area from 23º29'10"-23º29'45"S to 45º09'10"-45º10'00"W. Water and air temperature variation showed the highest correlation coefficient with the frequency of ovigerous females, r² = 0.73 and 0.68, respectively. However, an analysis of the set of environmental variables, revealed the photoperiod as the factor of highest association with the ovigerous frequency (r² = 0.68). This degree of association allow us to suggest that the breeding season duration of G. cruentata might have some variations over different latitudes, and such results could be quite diverse in populations from different latitudes

“…No verão, todavia, a freqüência de juvenis ficou em torno de 2%, embora tenha ocorrido uma elevada freqüência de fêmeas ovígeras durante a primavera e o verão. Provavelmente a reduzida presença de juvenis durante estas estações pode ser explicada pela ação da temperatura no desenvolvimento e maturação dos tecidos gonadais (ADIYODY & ADIYODY, 1970;WEAR, 1974) e sua ação catalítica sobre as diferentes fases larvais (BOOLOOTIAN et al, 1959). Segundo EMMERSON (1994), uma estratégia reprodutiva comum entre os crustáceos consiste em realizar a postura durante o verão, quando as temperaturas estão elevadas e o fitoplâncton mais abundante, o que facilita o desenvolvimento dos novos indivíduos.…”

ABSTRACT. Populational structure of the sympatric freshwater shrimps Potimirim glabra and Potimirim potimirim (Crustacea, Decapoda, Atyidae) in the Sahy River, Rio de Janeiro, Brazil. The aim of this work was to get some knowledge about the populational structure of the two sympatric freshwater shrimp species, Potimirim glabra (Kingsley, 1878) and Potimirim potimirim (Müller, 1881) in the Sahy River, Mangaratiba, Rio de Janeiro, Brazil. The specimens were sampled monthly from September 1997 to February 1999 by sieving the marginal vegetation, on rocky surface and among litter on river bottom, with 15-minute effort per sampling period. The animals were sorted sexed and their total and cephalothoracic length were measured. A total of 4,889 individuals were collected in Sahy river: 3,281 P. glabra and 1,608 P. potimirim. The sex ratio for all collected individuals was 1:1 for P. glabra and 1:2.3 for P. potimirim. In both populations, five sexual maturity stages were determined and the populations were constituted mainly of adult freshwater shrimps. This study shows the difference between the recruitment of juveniles along these species. The recruitment for P. glabra occurs throughout the year, except in Spring, while P. potimirim was recorded only in Autumn. The seasonal distribution of ovigerous females of P. glabra is similar to P. potimirim, with reproduction on Spring and Summer.KEYWORDS.

Este trabalho teve por objetivo obter conhecimento sobre a estrutura populacional de dois camarões de água doce simpátricos, Potimirim glabra (Kingsley, 1878) e Potimirim potimirim (Müller, 1881) no rio Sahy, Mangaratiba, Rio de Janeiro, Brasil. Os indivíduos foram coletados mensalmente durante o período de setembro de 1997 a fevereiro de 1999 utilizando-se peneiras, que foram passadas sob a vegetação marginal, superfície de rochas e pequenas poças d'água, num esforço de 15 minutos por coletor. Os animais foram separados quanto ao sexo e mensurados em relação ao comprimento total e do cefalotórax. Um total de 4.889 indivíduos foram coletados no rio Sahy: 3.281 P. glabra e 1.608 P. potimirim. A razão sexual observada foi de 1:1 para P. glabra e 1:2,3 para P. potimirim. Em ambas populações, cinco estágios de maturidade sexual foram determinados, sendo as populações constituídas principalmente por camarões adultos. O recrutamento de juvenis apresentou diferenças em ambas as espécies. O recrutamento de P. glabra ocorreu durante todo o período de estudo, exceto na primavera, enquanto que P. potimirim foi registrado somente no outono. A distribuição sazonal de fêmeas ovígeras de P. glabra é similar ao de P. potimirim, com reprodução na primavera e no verão.

“…Usually when the reproductive cycles of crustaceans are investigated, either some index relating to the state of gonad development through time is used (determined by weighing or histology, e.g., Armstrong 1988) or the proportion of ovigerous females in a population is monitored (Boolootian et al 1959;Giese 1959). Working on the reproductive cycle of Ovalipes punctatus, Du Preez & McLachlan (1984) used an index of gonad development.…”

“…obs.). Many species of crab have been found capable of increasing their reproductive potential by producing more than one batch of eggs between moults (Boolootian et al 1959;Hines 1982;Morgan et al 1983). If O. catharus had similar capabilities this would imply multiple egg 288 New Zealand Journal of Marine and Freshwater Research, 1993, Vol.…”

The annual reproductive cycle of Ovalipes catharus (White) was investigated by determining the proportion of mature females carrying eggs, in samples of crabs taken at dusk every 4 or 5 weeks for 22 months from Plimmerton Beach, near Wellington, New Zealand. Three peaks of egg-bearing were found over each breeding season: the first during August, the second through late November and early December, and the last during early January into early April. The average carapace width (CW) of crabs carrying eggs was 84.6 ± 9.65 mm and this average did not alter significantly during the year. Smaller female crabs (41-60 mm CW) were found carrying eggs predominantly during January and February. Captive O. catharus were able to produce a maximum of five batches of eggs during one intermoult period, from a single insemination. The average number of egg batches produced increased with crab size. Crabs < 50 mm CW produced only one egg batch before moulting, whereas those > 90 mm CW produced an average of three batches. Overall, the mean number produced was 2.6 batches. The period of incubation and the inter-batch period for captive females each became as short as 2.5 weeks during December and January. This was about half the time taken at the beginning and end of the egg-bearing season. No evidence was found for retention of sperm between moults. M89007
