“…When SACW reaches the bay, it causes a decrease in temperature and confinement of the shrimp population in shallower areas ( < 20 m). Similar results were also reported for the shrimp X. kroyeri by NAKAGAKI & NEGREIROS-FRANSOZO (1998) and CASTRO et al (2005), Rimapenaeus constrictus (Stimpson, 1874) by COSTA & FRANSOZO (2004b), the "Argentinean" shrimp Pleoticus muelleri Bate, 1888 by COSTA et al (2004) and the rock-shrimp Sicyonia dorsalis Kingsley, 1878 by COSTA et al (2005b), all in Ubatuba Bay.…”

“…The spine-shrimp showed continuous reproduction in the Ubatuba region: ovigerous females were found year-round, in spite of being more frequent during winter. Similar results were found by COSTA & FRANSOZO (2004b) for the peneid R. constrictus in the same region, and by GALVÃO & BUENO (1999) and MOSSOLIN & BUENO (2002) for the carideans Atya scabra (Leach, 1815) and Macrobrachium olfersi (Wiegmann, 1836), respectively, from the Municipality of São Sebastião, which is located near Ubatuba Bay at the same latitude. The most frequent breeding period was late spring and summer.…”

Population biology of spine shrimp Exhippolysmata oplophoroides (Holthuis) (Caridea, Hippolytidae) in a subtropical region, São Paulo, Brazil

The population biology of Exhippolysmata oplophoroides (Holthuis, 1948) was studied in Ubatuba Bay (23º26'S, 45º02'W), Ubatuba, São Paulo, Brazil, from September/1995 to August/1996. Each sampling comprised eight transects (14 000 m² each), sampled monthly with three repetitions. The specimens were classified with respect to the presence or absence of eggs in the abdominal appendages. Spine-shrimps occurred only on six transects, being most abundant on transect II, with the highest incidence in late spring and throughout the summer months. Ovigerous and non-ovigerous shrimps were present year-round, in an approximately similar proportion (1:1). Site II in Ubatuba Bay is characterized by high salinity and oxygen values, temperature between 26 and 29ºC, low organic matter content in the sediment, and a bottom composed of very fine sand; these environment and biological features allow the establishment and maintenance of the population of E. oplophoroides.

“…A number of studies have found that the reproductive cycle of penaeid shrimp is typically defined by the maturation of the females (Quintero & Gracia, 1998;Crocos et al, 2001;Cha et al, 2002;López-Martínez et al, 2005;Yamada et al, 2007). Therefore, few analyses have focused on the maturity of the males, in which the size at first maturity can be defined by the proportion of specimens with joined or unjoined petasma (Costa & Fransozo, 2004;Sobrino & García, 2007). In aquaculture research, by contrast, the analysis of the reproductive condition of the males are more detailed (Ceballos-Vázquez et al, 2003;Braga et al, 2010;Silva et al, 2015a).…”

ABSTRACT. The present study aimed to investigate the reproductive cycle and size at first maturity of Penaeus schmitti through a macro and microscopic approach. Between August 2011 and July 2012, 1169 specimens were collected by an artisanal fishing vessel operating a double trawl off the coast of Pernambuco, northeast Brazil. The total proportion of males (42%) was significantly lower than females (58%), corresponding to the sex ratio of 1:1.38. The total body length at first ovarian maturation (TL50) in females was estimated at 14.2 cm. The ovarian development was divided into four distinct stages based on histological characteristics and visual observations. This is the first reported occurrence of vitellogenic oocytes in the spent stage of P. schmitti, indicating a rapid ovarian maturation after spawning. Furthermore, the frequency of maturation stages, diameter of oocytes and gonadosomatic index were distributed homogeneously throughout the study period, reinforce a continuous reproductive cycle for P. schmitti population in northeastern Brazil.

“…A ACAS também eleva os valores de clorofila-a nesta região, resultando no aumento de fito e zooplâncton, sendo este de fundamental importância para o crescimento e sobrevivência das larvas dos decápodes (COSTA e FRANSOZO, 2004). Provavelmente, a disponibilidade de alimento na primavera, em decorrência da presença da ACAS na Baía de Santos, Estado de São Paulo, propiciou um recrutamento mais efetivo no verão se comparado ao restante do ano.…”

RESUMOEste trabalho investigou a maturidade sexual, o período reprodutivo e de recrutamento (ambos relacionados com a temperatura e a salinidade da água), e a proporção sexual de Xiphopenaeus kroyeri na Baía de Santos, SP. Os camarões foram capturados mensalmente, de junho de 2008 a maio de 2009, em quatro pontos de amostragem. Os indivíduos foram mensurados, analisados quanto ao sexo e o estágio de desenvolvimento reprodutivo foi determinado macroscopicamente. As fêmeas apresentaram valor médio de comprimento da carapaça (mm) maior que os machos e atingiram a maturidade fisiológica com valor superior, i.e., 25,5 mm para fêmeas e 16,8 mm para machos. O período reprodutivo foi contínuo, com maior proporção de fêmeas reprodutivas no outono. Apesar de não significativo, em fevereiro houve um pico similar a março de fêmeas reprodutivas. Entre agosto e outubro ocorreu um pico intermediário destas fêmeas que contribuiu para o recrutamento no verão. A menor quantidade de juvenis após a principal desova (fevereiro, março e abril) pode ser explicado pela migração ou pelo efeito da abertura da pesca, que ocorre em junho. A proporção entre os sexos foi próxima à 1:1, porém, em escala espacial, notou-se maior quantidade de fêmeas reprodutivas em locais mais rasos. Esta distribuição diferencial entre os sexos pode estar associada à estratégia reprodutiva das fêmeas, neste caso, áreas mais apropriadas para a desova. O atual defeso ocorre entre março e maio e, pelos resultados obtidos sobre a frequência de fêmeas reprodutivas, sugere-se a inclusão de fevereiro.Palavras chave: maturidade; reprodução; recrutamento; proporção sexual; Xiphopenaeus kroyeri POPULATION AND REPRODUCTIVE BIOLOGY OF THE SEABOB SHRIMP IN SANTOS BAY, SÃO PAULO ABSTRACTWe investigated the sexual maturity, reproductive period and juvenile recruitment (both associated with salinity and temperature of bottom water) and sex-ratio of Xiphopenaeus kroyeri in Santos Bay, São Paulo.
