Resumo: Moina minuta, a tropical species of Cladocera, was selected for the study of medium size at maturity and female egg production, due to its abundance and frequency in samples during low-water season in 1997 and high-water season in 1998, in Amapá Lake, Western Amazônia. The primiparous female had a size of 330 µm and 340 µm in low and high water, respectively. Moina individuals reached maximum size during high water (595µm). The medium size of the ovigerous females, in low water was 501 µm, producing an average of 4.41 eggs/female, while in high water, it was 533µm, with an average egg production of 4.84 eggs/female. The results, analyzed by the t test and Fischer’s F test, showed that there were no statistical differences in size among individuals (t= -10.69, F=1.20 and P>0.1227), nor among ovigerous females (t= -4.45, F=1.02 and P>0.8906), considering the two seasons.

A primipara apresentou tamanhos de 330 µm e 340 µm, respectivamente, na fase de águas baixas e fase de águas altas. Os indivíduos de M. minuta alcançaram tamanho máximo nas águas altas (595 µm). O tamanho médio das fêmeas ovígeras, na fase de águas baixas, foi de 501 µm, produzindo em média 4,41 ovos/fêmea, enquanto que na fase de águas altas foi de 533 µm, com uma média de 4,84 ovos/fêmea. Os resultados, demonstrados através da análise do teste t e teste F de Fischer, mostraram que não houve diferenças estatísticas nos tamanhos dos indivíduos (t= -10,69, F=1,20 e P>0,1227), como também nos tamanhos das fêmeas ovígeras (t= -4,45, F=1,02 e P>0,8906), considerando os dois períodos sazonais estudados.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/227810.4025/actascibiolsci.v24i0.2278Acta Scientiarum.
