“…Some authors consider that the main events of the embryonic development occur from the onset of cleavage to the formation of gastrula (Nagao et al 1999, Müller et al 2003, but changes occurring during this period are difficult to observe in live eggs without special techniques. After inward blastoderm migration by cellular proliferation into the yolk mass (Adiyodi 1988), primordial structures start growing and extend ventrally, being easy to observe and describe in live eggs.…”

“…Para cálculo do número de ovos a serem medidos foi aplicada a fórmula n = 1.96.s/l, onde s = desvio padrão da amostra inicial (n = 5) e l = 10% da média da amostra inicial (NAZARI et al 2003), a partir da qual se obteve o n amostral de 10 ovos por dia embrionário.…”

“…Macrobrachium olfersi é a espécie mais representativa dentre os palemonídeos coletados na Ilha de Santa Catarina, cujas fêmeas alojam seus numerosos ovos em uma câmara incubadora, por um período relativamente curto de tempo (AMMAR et al 2001, NAZARI et al 2003. Tais características, típicas da maioria dos malacostracos, associadas à adaptabilidade da espécie às condições experimentais permitem o acompanhamento e a retirada diária de amostras de ovos viáveis ao longo de todo período de incubação.…”

“…Information or documentation dealing with physiology, reproduction and embryology of brachyuran crabs are almost entirely lacking (Garcia-Guerrero & Hendrickx 2004), where the other groups of decapod crustaceans including the caridean shrimp, marine lobster and river crayfish, have received most of the attention and their embryology is better documented (Clarke et al, 1990, Helluy & Beltz 1991, Sandeman & Sandeman 1991, Nazari et al, 2000, Müller et al, 2003, Garcia-Guerrero et al, 2003.…”
