Molecular identification of Cichla (Perciformes: Cichlidae) introduced in reservoirs in Southern Brazil

Abstract: Species of peacock bass were introduced in several watersheds in South America and worldwide, mainly due to its importance to sport fishing, by being a fighting fish. A recent revision of the genus Cichla showed that the species introduced in reservoirs of the South, Southeast and Northeast regions of Brazil are two new species, described as Cichla kelberi (yellow peacock bass) and Cichla piquiti (blue peacock bass), erroneously identified as C. monoculus and C. ocellaris. With the purpose to identify the popu… Show more

“…While molecular validation for the occurrence of other species of yellow peacock bass ( i.e. C. monoculus ) in non‐native systems of south‐eastern and southern Brazil is still in discussion (Oliveira et al , ; Briñez et al , ), the findings of the current study strongly confirm that C. kelberi is the main Cichla spp. that has invaded the reservoirs in the Paraíba do Sul River basin.…”

“…This difference, together with the exclusive record of haplotype H6 for the population at ITU and the three haplotypes (H2, H8 and H9) not detected within the native area, support the occurrence of multiple introductions through the south‐eastern and southern Brazilian systems. The occurrence of multiple C. kelberi introductions was previously detected by Oliveira et al () and Briñez et al () for the Porto Rico floodplain. Therefore, the polymorphisms indicating the occurrence of multiple C. kelberi introductions in the Pereira Passos and Paracambi reservoirs, two of the most downstream reservoirs in the Paraíba do Sul River that were studied, could be related to their proximity ( c .…”

“…É importante ressaltar que nesta época havia apenas cinco espécies válidas identificadas: , 1986). Embora não presente na planície de inundação do alto rio Paraná, a espécie Cichla monoculus é documentada em outras regiões da bacia do alto rio Paraná a montante, como por exemplo na represa de Capivara, Taquaruçu e Rosana (BRIÑEZ et al, 2013) e a sua introdução, através de escapes de tanques do rio Tibagi é bem documentada (ORSI; AGOSTINHO, 1999). A segunda espécie presente na planície de inundação, C. piquiti, é conhecida localmente como tucunaré azul, e tem sua diferenciação evidenciada pela combinação de 89 a 98 escamas na linha lateral superior e no padrão de coloração no adulto que inclui cinco ou mais faixas verticais escuras abaixo da nadadeira dorsal (Figura 2).…”

“…Análises genéticas de populações de Tucunaré nas áreas invadidas na planície de inundação do alto rio Paraná, entretanto, confirmaram a hipótese de múltiplas introduções de espécimes das diferentes regiões em diferentes pontos da bacia (BRIÑEZ et al, 2013;OLIVEIRA et al, 2006).…”
