| O efeito estimulante da spiperona e da naloxana sob a maturação ovariana foram avaliados em fêmeas de Aegla uruguayana Schmitt, 1942 e, para isto, tais neuroreguladores foram incorporados ao alimento e administrados a uma dose de 10-8 mol/animal a cada sessão de alimentação. Fêmeas adultas foram coletadas com puçá em um arroio próximo à cidade de Salto, Província de Buenos Aires, Argentina. Dez fêmeas foram sacrificadas, medidas, pesadas e os seus ovários foram retirados e pesados para a determinação do índice gonadossomático (IG). As demais fêmeas (30) foram divididas em três grupos experimentais - (a) controle: alimentadas com pellets controle composto por ração para peixe - 34% de proteína e 43% de proteína; (b) spiperona: alimentadas com pellets... |

| The goal of this study was to evaluate the effects of seasonal variations on energy metabolism in different tissues of the freshwater crayfish Parastacus brasiliensis (von Martens, 1869). Crayfish were collected monthly from January 2001 to January 2003 in São Francisco de Paula, Rio Grande do Sul, Brazil, in a stream and in a culture tank. Haemolymph samples were collected from each crayfish in the field with a syringe, by puncturing the membrane at the base of the chelipeds. Hepatopancreas, gills, and abdominal muscle were removed for determination of free glucose, glycogen, total lipids, and triglycerides. The haemolymph samples were used for determination of glucose, total proteins, total lipids, and triglycerides. Statistical analysis revealed... |

| The goal of this study was to evaluate the effect of a high-carbohydrate diet (HC) and a high-protein diet (HP) on the metabolism of the crayfish Parastacus brasiliensis (Von Martens, 1869), collected in different seasons and maintained in the laboratory for 15 days. Crayfish were collected monthly from January 2002 to January 2004 at São Francisco de Paula, Southern Brazil, in Guarapirá stream. In the laboratory, the animals were kept submerged in aquariums under controlled conditions. They were fed ad libitum, for 15 days with either a HC or HP diet. At the end of this period, haemolymph samples were collected, as were hepatopancreas, gills, and abdominal muscle that were removed for determination of glycogen, free glucose, lipids, and triglycerides.
