Age, growth, mortality and yield per recruit of the dourado Salminus brasiliensis, Corumbá Reservoir, Goiás State, Brazil

Abstract: In order to evaluate the fate of the migratory species dourado Salminus brasiliensis in the first years of impoundment in Corumbá Reservoir we estimated age, growth, mortality and yield per recruit. Samplings were carried out monthly in Corumbá Reservoir and its main tributaries (Goiás State) from March 1998 to February 1999 using gillnets. After one year of impoundment, age was estimated from scales and the maximum number of rings was six for males and five for females. Rings are formed annually in May and Ju… Show more

“…Outro tema importante abordado em parte dos estudos foi sobre introdução / manutenção de espécies exóticas nos reservatórios e seus efeitos nas espécies nativas (AGOSTINHO et al, 2004;CARVALHO, 2011A;CARVALHO, 2011B;CARVALHO, 2013;SCHORK et al, 2013;DAVID et al, 2016;SANTA-FÉ et al, 2016 , 1998;BAIRD et al, 2004;TOS et al, 2009;DORIA et al, 2012;HEGG et al, 2015;DUPONCHELLE et al, 2016;SIDDONS et al, 2017). No caso de Tucuruí, os grandes bagres migradores podem ter sido os mais prejudicados com a interrupção do fluxo migratório promovido pela barragem (GARAVELLO et al, 2010).…”

“…Com relação a biologia e ecologia, os estudos focaram suas análises em aspectos de crescimento, mortalidade, reprodução, dinâmica alimentar, riqueza, diversidade, população, assembleia de peixes e distribuição (ALI, 1996;GOMES;MIRANDA, 2001;TORDECILLA-PETRO et al, 2005;JIMÉNEZ-BADILLO, 2006;AGOSTINHO et al, 2007;COLL et al, 2007;MAIA et al, 2007;ARAYA et al, 2008;ZHU;CHANG, 2008;TOS et al, 2009;KANTOUSSAN et al, 2009;MESSINA et al, 2010;GARCIA-LIZARRAGA et al, 2011;CARVALHO, 2011a;QUARCOOPOME et al, 2011;CARVALHO, 2012;ALVAREZ et al, 2013;GERASIMOV et al, 2013;HAMID;MANSOR, 2013;CAMARGO et al, 2015;SÁ-OLIVEIRA et al, 2015;AGOSTINHO et al, 2016;DAVID et al, 2016).…”

“…We are not aware of any study on age-structure of pirá, but we suspect the 10-year generation length (GL) used for including pirá in the 2014 Brazilian red list was an overestimate. Our concern is based on maximum age records for other large Brazilian freshwater fishes, which are: 6 years for Salminus brasiliensis (Tos et al, 2009), 8 years for Prochilodus lineatus (Santana, Minte-Vera, 2017) and Pseudoplastystoma reticulatum (Francisco et al, 2011) and 10 years for Arapaima gigas (Queiroz, 2000) and Pseudoplatystoma corruscans (Mateus, Petrere, 2004). Since the IUCN (2001) definition of generation length used for listing species in the 2014 Brazilian red list was the average age of parents of the current cohort, the 10-year GL used for pirá is higher or equal to the maximum age reported for some other Brazilian large fish.…”
