Abstract: Abstract:In the Amazon the fishing is considered an important source of income and animal protein for the people in the region. Among the different fish species that landed in the market and fairs stand out Triportheus albus, T. angulatus and T. auritus. Considering the reduction of some fish stocks in the region, both the quantity and the size of some species, the research proposes to determine the growth parameters, mortality and length-weight relation of these species in floodplain lakes, Manacapuru, AM. . … Show more

“…Acestrorhynchus falcirostris, A. inermis, M. asterias, M. ternetzi and T. trilobatus presented negative allometric growth, which is expected for fish species with an elongated and/or rounded body shape, which is the case of species of the present study (Araújo & Vicentini, 2001); However, this pattern indicates that the fish is growing in length as expected, but its biomass gain is not corresponding to its length, different from what happens when the growth is isometric that is ideal for fish (Tavares-Dias, Araújo, Gomes, & Andrade, 2010), as occurred for A. falcatus, H. unimaculatus and H. aimara of the present study. However, b values of LWR are strongly influenced by gonadal maturity, feeding, seasonality, habitat and fish life stage (Froese, 2006;Prestes, Soares, Silva, & Bittencourt, 2010;Oliveira et al, 2018). Of the eight species studied here, only A. falcirostris, A.…”

“…Petrere, 1983;Isaac and Ruffino, 1996). Regarding length-weight relationships in the Amazon, data are available, among others, in Penna et al (2005), Bevilaqua and Soares (2010), Prestes et al (2010), Giarrizzo et al (2011) and Quara de Carvalho Santos et al (2012). However, due to the high diversity of fish, information related to length-weight relationships is still incipient.…”

“…However, as the annual temperature variation in tropical regions is small, it was believed that it would not be possible to identify growth marks in calcified structures (Fonteles Filho, 2011) and, consequently, that this method could not be used to determine age in tropical fish species. For this reason, until recently, growth parameters in these regions were generally estimated indirectly from lengthfrequency data (Petrere Jr., 1983;Isaac & Ruffino, 1996;Ruffino & Isaac, 1999;Santos Filho & Batista, 2009;Bevilaqua & Soares, 2010;Campos & Freitas, 2010;Prestes et al, 2010). However, recently Fabré & Saint-Paul (1998) noted that flooded areas in tropical regions have sufficient seasonal change in water level to induce the appearance of growth checks in calcified structures in fishes.…”
