“…Rhamdia quelen, commonly known as jundiá, is a fish greatly accepted by the consumer market due to its flavorsome meat and lack of intramuscular spines (Carneiro & Mikos, 2005). Its productive potential makes it an important species for the Brazilian aquaculture, which is well represented by the South region.…”

ABSTRACT. Transportation of live fish is routinely done in aquaculture; therefore, the aim of this study was to analyze the water quality and survival rate of Rhamdia quelen fry (2.55±0.44 g) following 4, 8 and 12h of simulated transportation, at stock densities of 30 and 60 fry 5 L -1 and temperatures 15, 20 and 25 o C. Dissolved oxygen, pH, electrical conductivity, total ammonia, nitrite, nitrate, turbidity, total alkalinity and survival were analyzed. Temperature and time had a significant influence on ammonia, pH, electrical conductivity, and dissolved oxygen levels, and fish died after 12 hours of transportation simulation when kept at 20 and 25ºC. The density directly affected the water quality parameters, such as the increase in electrical conductivity and turbidity, and decrease in dissolved oxygen and pH at the density of 60 fish 5 L -1 . In conclusion, the transportation of R. quelen fry should be carried out at temperatures between 15 and 25°C, for periods of less than 12 hours, and at stock density of up to 6 fish per liter of water so as not to impair the homeostasis of the fry, and consequently, their survival.Keywords: aquaculture; ammonia; loading densities; management; mortality.Qualidade de água e sobrevivência de alevinos de Rhamdia quelen submetidos a transporte simulado em diferentes densidades e temperaturas RESUMO. O transporte de peixes vivos é uma prática comum na aquicultura. Por isso, o objetivo do presente trabalho foi analisar a qualidade de água e sobrevivência de alevinos Rhamdia quelen (2,55±0,44 g) seguindo 4, 8 e 12h de transporte simulado, em densidades de 30 e 60 peixes 5 L -1 e em temperaturas de 15, 20 e 25 o C. Foram analisados: oxigênio dissolvido, pH, condutividade elétrica, amônia, nitrito, nitrato, turbidez, alcalinidade e sobrevivência. A temperatura e o tempo tiveram influência significativa nos níveis de amônia, pH, condutividade elétrica e oxigênio, e verificou-se mortalidades após 12 horas de simulação de transporte nos peixes mantidos a 20 e 25ºC. A densidade influenciou diretamente nos parâmetros de qualidade de água, tais como o aumento da condutividade elétrica e turbidez e a diminuição de oxigênio dissolvido e pH na densidade de 60 peixes 5 L -1 . Em conclusão, recomenda-se o transporte de alevinos de R. quelen em temperaturas entre 15 e 25°C, em períodos inferiores a 12 horas. E a densidade de seis peixes por litro de água não compromete a homeostase dos alevinos, e consequentemente sua sobrevivência.

“…The fact that both fish species had the same parasites may be explained by the fact that they share biological features, besides the fact that they co-exist geographically. Additionally, both are omnivorous, opportunistic, and scavengers of lagoon and river bottoms (LOWE-McCONNELL, 1999;GOMES et al, 2000;BIZERRIL;PRIMO, 2001;CARNEIRO;MIKOS, 2005;TEIXEIRA;ARAÚJO, 2005).…”

Forty-one specimens of mandi-amarelo Pimelodus maculatus Lacépède, 1803 (Siluriformes: Pimelodidae) and 54 specimens of jundiá Rhamdia quelen (Quoy & Gaimard, 1824) (Siluriformes: Heptapteridae) were collected from the Paraíba do Sul River, Volta Redonda, State of Rio de Janeiro, Brazil between November 2007 and October 2008. These fish underwent necropsy so their infracommunities of metazoan parasites could be studied. The same three species of parasites were collected in the two fish species studied. These were one monogenean, one nematode, and one hirudinean. Cucullanus pinnai (Travassos, Artiga, and Pereira, 1928) (Nematoda: Cucullanidae) and Aphanoblastella sp. (Monogenea: Dactylogyridae) were the dominant species with the highest prevalence in P. maculatus and R. quelen. The parasite species of P. maculatus and R. quelen showed an atypical over-dispersed pattern of distribution. No parasite species showed significant correlation between the body total length of the siluriform hosts and their prevalence and abundance. The parasite species richness showed a mean value of 0.87 ± 0.67 (0 -2) and 0.57 ± 0.56 (0 -2) in P. maculatus and R. quelen, respectively, and no correlation with the body total length.
