“…Given that multiple male and female individuals contribute to each brood, the spawning behavior of Arapaima gigas is likely to be complex. Since males are the primary caregivers and guardians of the brood, males may chose to mate with multiple females, and the contribution of additional males to the brood would then likely to be result of parasitic behavior of satellite males (Roldán & Soler, 2011). Another, not necessarily exclusive possibility, is the existence of alloparental care, where other pairs spawn in the nest of the caregiver male (Wisenden, 1999).…”

“…Unrelated fry in the male's clutch may also be the result of parental-care parasitism, but may have similar indirect benefits as alloparental care. Parental-care parasitism is defined as an interaction in which an individual (extra-pair) obtains reproductive benefits while reducing or completely eliminating its own costs of parenting by exploiting any type of offspring care provided by other individuals (Roldán & Soler, 2011), such as the protection to offspring provided by the male caregiver in Arapaima gigas.…”

Arapaima gigas is one of the largest freshwater fishes of the world. It is socially monogamous, forming pairs, constructing a nest and providing parental care. We performed a paternity analysis under three scenarios in captive, semi-natural and natural areas using 10 microsatellite markers. As a positive control, we analyzed three pairs and their offspring isolated individually in artificial breeding ponds (a priori very high probability of monogamy). We then analyzed two samples of offspring from large artificial ponds with multiple adults but only one reproductive pair (a priori high probability of monogamy), two samples from semi-natural breeding station with multiple adults but only one reproductive pair (a priori high probability of monogamy), and a sample from a natural lake with multiple adults, some potentially breeding (a priori medium probability of monogamy). Analysis of patterns of Mendelian heredity suggested an extra-pair contribution for all broods except the positive controls. Similarly, results based on multilocus analysis estimated at least two sib-groups per nest. These results reject monogamy as a system of breeding in Arapaima gigas. From a management perspective, this behavior may be exploited to maintain genetic diversity in captive and as well in wild populations of Arapaima gigas.O pirarucu Arapaima gigas é um dos maiores peixes de água doce do mundo. É socialmente monogâmico, forma casais, constrói ninhos e fornece cuidado parental. Com o objetivo de acessar o sistema de acasalamento do pirarucu, analisamos três cenários: em áreas de cativeiro, semi-naturais e naturais, utilizando 10 marcadores microssatélites. Como controle positivo, analisamos três casais e suas ninhadas isolados em açudes individuais (probabilidade a priori muito alta de monogamia). A seguir, analisamos duas amostras de ninhadas de um açude com vários adultos, mas somente um casal reprodutivo (probabilidade a priori alta de monogamia), duas amostras de estação de criação semi-natural com vários adultos mas somente um casal reprodutivo (probabilidade a priori alta de monogamia), e uma amostra de lago natural com vários adultos alguns potencialmente em fase de reprodução (probabilidade a priori média de monogamia). Análises de padrões mendelianos de hereditariedade sugerem contribuição extra-par para todas as ninhadas, exceto as do controle positivo. Similarmente, resultados baseados em análises multilocus realizadas no programa KINALYZER estimaram pelo menos dois grupos-irmãos por ninhada. Nossos resultados rejeitam a monogamia como sistema de acasalamento em Arapaima gigas. Da perspectiva de manejo, esse comportamento pode ser explorado para manter a diversidade genética em cativeiro assim como em populações naturais de Arapaima gigas.

“…Avian brood parasitism is a type of parental care parasitism (Roldán and Soler, 2011) in which some individuals (the parasites) place their eggs in the nests of other species or conspecifics, the hosts Johnsgard, 1997). Hosts usually incubate these eggs and rear the chicks hatched from them as their own Johnsgard, 1997).…”

“…The energetic costs of calling and male combat is high (e.g., Ryan, 1988;Wells, 2001), and a significant body mass reduction occurs in this population during the middle and late breeding season (Zheng et al, 2010). Further, the male may also benefit from possible paternal care provided to his offspring by a subsequent male (Roldán and Soler, 2011). Several sources of data support this possibility.…”
