| The objective of this work was to investigate artificial fertilization and the duration of sperm motility in pacu with different insemination doses, water volume, and in natura semen preservation. It was carried out four experimentsfor evaluation of insemination doses (7x10³, 7x10(4), 7x10(5), 7x10(6), and 7x10(7) spermatozoa oocytes-1) on the artificial fertilization of oocytes; the effect of water volume (0.5, 15.0, 30.0, 45.0, and 60.0 mL water mL-1 of oocyte) with insemination doses of 105,481 and 210,963 spermatozoa oocytes-1; the effect of semen dilutions (0.005, 0.05, 0.5, and 5.0 µL semen mL-1 of water) on sperm motility duration; and the effect of storage at 15ºC for 9h on sperm motility duration and sperm survival ratio. The highest results... |

| ABSTRACT By using informetric tools, we evaluated the contribution and impact of the open source computer-assisted sperm analysis (CASA) software on sperm studies, especially pertaining to fish. The article was cited 125 times between 2007 and 2014 in four publication types (articles, doctoral dissertations, master’s theses, and books). Among articles, the number of citations increased at rate of three citations per year and the calculated h-index was 17. Of the studies that cited Wilson-Leedy and Ingermann (2007), fish were the main group of organisms studied (61 articles); of these, 34 articles used the open source CASA, covering 23 marine or freshwater species. Studies conducted in 12 countries were published in 21 journals. Four ways of knowledge... |

| Um experimento foi conduzido com o objetivo de avaliar os desempenhos reprodutivo e zootécnico e a deposição de lipídios no tecido hepático de fêmeas de tilápia-do-nilo alimentadas com rações contendo diferentes níveis de energia digestível, obtidos pela inclusão de óleo de soja. Foram utilizados 100 reprodutores e 300 reprodutoras, distribuídos em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições. Os reprodutores, machos e fêmeas, foram alimentados com rações contendo, por quilograma, 35% de proteína bruta e 2.700, 2.950, 3.200, 3.450 ou 3.700 kcal de energia digestível. Os animais foram mantidos em hapas por 93 dias. O desempenho reprodutivo e zootécnico não foi influenciado pelos níveis energéticos das rações, o que pode... |

| The objective of this study was to evaluate the effects of water volume and water temperature on the sperm motility duration and the number of spermatozoa, and the water volume on the fertilization rates of oocytes of Rhinelepis aspera. Experiments were carried out to evaluate the effect of semen dilutions (1.74×10-5, 1.74×10-4, 1.74×10-3, 1.74×10-2, 1.74×10-1 and 1.00 mL of sperm.mL-1 of water) and water temperature (5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 ºC) on spermatozoa motility duration. In addition, the effects of insemination dose (7×10³, 7×10(4), 7×10(5), 7×10(6) and 7×10(7) spermatozoa.oocyte-1) and water volume (1.0, 30.0, 60.0, 90.0 and 120.0 mL water.2.0 mL-1 oocytes) on the artificial fertilization rates of oocytes were evaluated. The... |

| The objective of this study was to assess the abundance, attributes of assemblages, and spatial and temporal distributions of fish larvae and their relationships with some abiotic variables in two floodplain lakes with different degrees of connection to the Paraná River in Ilha Grande National Park, PR, Brazil. Four sampling sites were chosen, two in each floodplain lake. Night samples were taken with plankton nets during three spawning seasons (monthly, from October to March) from 2001 to 2005. The highest diversity and abundance were recorded at Saraiva Lake, with 25 taxa being identified. In Xambrê Lake, only sedentary species were captured, and the most abundant species were Plagioscion squamosissimus and Hypophthalmus edentatus. The greatest abundance... |

| This study characterized the morphological differences among migratory fish species from the Paraná River Basin. A total of 177 adult fish of Leporinus elongatus, Leporinus macrocephalus, Prochilodus lineatus, Salminus brasiliensis, Pimelodus maculatus, Pinirampus pirinampu, Pseudoplatystoma corruscans, Pterodoras granulosus, and Rhaphiodon vulpinus were sampled in the Canal da Piracema, a fish passage system at Itaipu Dam, Paraná River. The migratory species were analyzed through 22 morphometric measurements and fineness ratio to identify morphological patterns related to swimming performance. Four species groups were indicated by the Cluster analysis: I) R. vulpinus; II) P. corruscans; III) L. macrocephalus, L. elongatus, P. lineatus, P. maculatus, and... |

Os reprodutores foram alimentados com rações contendo 35% de proteína bruta e submetidos ao manejo reprodutivo em hapas por 101 dias. O melhor resultado de concentração espermática e percentual de espermatozoides normais foram obtidos para... |
