Abstract: Rhamdia quelen (Jundiá) is a catfish species of great interest to fish producers and researchers due to several favorable characteristics for inclusion in the Brazilian list of commercially raised fish. It has a wide geographical distribution, with occurrences reported from Central Argentina to South Mexico. Studies on the biological aspects of this species have been limited to captive adult fishes that were researched for farming purposes. Research related to ichthyoplankton has provided valuable information … Show more

“…The large number of small and medium-sized species with fast growth is associated with the higher temperatures recorded in the tropics. Pauly (1998a) Rhamdia quelen is a catfish species, prefers calmer and deeper water along banks and vegetation with a sand or mud bottom (Silva et al, 2011). Despite the large distribution of this species, from northern Mexico to southern Argentina (Graça & Pavanelli, 2007), studies on the biological aspects of this species have been primarily conducted on captive adult fish for farming purposes (Silva et al, 2011).…”

“…South American fresh water rheophilic fishes present particular aspects in their reproductive biology such as: a short breeding season that occurs exclusively in summer months (during rainy season); the absolute necessity of using hormones to induce oocyte maturation and spawning (spontaneous spawning or ovulation in captivity has never been reported) (Zaniboni-Filho & Weingartner, 2007); and most importantly, the obvious differences regarding climate characteristics between tropical and temperate regions. For species native to temperate regions, photoperiod and temperature are the main environmental factors controlling the process of sexual maturation and reproduction (Mañanós et al, 1997;Bromage et al, 2001;Almeida et al, 2011), while pH, fluviometric level, dissolved oxygen, temperature, rainfall, electrical conductivity are considered to be of major importance to the reproduction of South American tropical species (LoweMcConnell, 1987;Barthem & Goulding, 1997;Silva et al, 2011).…”
