“…During sampling, certain shoreline areas (shallow with muddy bottoms) presented a greater number of nests and mated pairs of C. kelberi. In cichlids that practice bi-parental care, there is a division of labour, wherein the females guard the eggs and larvae while the males patrol and repel any possible predators (Barlow, 1974). Thus, larger males would have the advantage in the determination of territories at the initiation of the reproductive season and in the protection of the offspring (Zaret, 1980).…”

The objective of this study was to characterize the reproduction of Cichla kelberi in an artificial lake, located in the municipality of Leme, in the state of São Paulo, Brazil. Breeding occurred in spring, and summer. The L 50 and the L 100 of this species were 192 and 235 mm (L 50 ), for males and females, respectively, and 290 mm (L 100 ) for both sexes. Spawning was parceled. The oocytes matured at a size of 428.4 µm, reaching their maximum at 2,203.2 µm. A mean of fecundity were of 12,129.2 oocytes, with the mean of oocytes in each batch of 4,897.7. This species has external fertilization, is nonmigratory, and with parental care of the young. Various attributes of the peacock bass make their introduction a temptation. However, due to their feeding and reproductive characteristics, they have no natural predators, making it difficult to control their population growth or eradicate them.Keywords: exotic specie, fish, peacock bass, reproduction, Cichla kelberi.

“…Alternatively, the specialization in the execution of parental duties may be the result of differential ability to perform some particular tasks. For example, males usually are bigger than females and could be more effective in the territorial defense and, therefore, they would emphasize this activity (Barlow, 1974;Schwanck, 1989;Awata & Khoda, 2004;Itzkowitz et al, 2005).…”

“…These fish are known for their complex reproductive behavior, with different mating system that encompass territorial defense, elaborate mechanisms of mate choice and prolonged parental care (e.g., Barlow, 1974Barlow, , 2000Ripley & Lobel, 2005;Balshine & Buston, 2008;Khoda et al, 2009). Among Neotropical cichlids, monogamy and biparental care are the most common strategies (Keenleyside, 1991), which involves male and female cooperation over the reproductive cycle (Timms & Keenleyside, 1975;Keenleyside & Bietz, 1981;Snekser & Itzkowitz, 2009), a less widespread behavior among teleost fishes (Balshine & Buston, 2008).…”

“…Cooperation may occur based on division of labor, mainly in the first reproductive phases (Barlow, 1974;Rogers, 1988), with females investing more time rearing brood while males invest more time in the territorial defense. These differences tend to reduce or disappear with brood development (Barlow, 1974;Neil, 1984;Keenleyside, 1991).…”

“…These differences tend to reduce or disappear with brood development (Barlow, 1974;Neil, 1984;Keenleyside, 1991). The exchange of parental roles allow parents to alternate vigilance/feeding activities (Ward & Samarakoon, 1981) and as a consequence, keep better health conditions (Perrone & Zaret, 1979).…”

We described the reproductive behavior of the small South American cichlid Laetacara araguaiae in streams from Brazil. We predicted that this species will show reproductive cooperation and division of labor between males and females in a similar way presented by other substrate-spawner cichlids. Thus, we studied 34 pairs in the pre-spawning (n = 11), egg/wriggler (n = 11) and fry (n = 12) phases. In the pre-spawning phase both sexes become involved in nest building and territorial defense, but females emphasizes building nest (p = 0.03), while males invest more time in territorial defense (p = 0.04). After spawning, male and female alternate between rearing eggs and defending nest in the territory. In the egg/wriggler phase females devotes more time rearing the brood while males remain defending territory (p = 0.02). These differences disappear when young are in the fry stage, and parents jointly stay closer to fry (p = 0.98). However, at this phase, there is a reduction in the frequency of threats shown by males (p<0.01) and an increase in the frequency of attacks shown by female (p<0.01) that could be a response to an increased demand for parental defense. Our results indicate that the reproductive cooperation between males and females of L. araguaiae is marked by division of labor in the early reproductive phases and by sharing of parental duties as brood develops.Descrevemos o comportamento reprodutivo do pequeno ciclídeo sul-americano Laetacara araguaiae em riachos do Brasil. Predizemos que essa espécie apresenta cooperação reprodutiva e divisão de trabalho entre machos e fêmeas, como ocorre em outras espécies de ciclídeos substrate-spawners. Assim, estudamos 34 casais nas fases pré-acasalamento (n = 11), ovo/larva (n = 11) e prole natante (n = 12). Na fase pré-acasalamento ambos os sexos envolvem-se na construção de ninhos e na defesa territorial, mas as fêmeas enfatizam a construção de ninho (p = 0,03), enquanto os machos investem mais na defesa do território (p = 0,04). Após a desova, machos e fêmeas alternam entre a manutenção dos ovos e a defesa do ninho. Na fase ovo/larva as fêmeas despendem mais tempo em atividades de manutenção da prole, enquanto os machos investem mais na defesa do território (p = 0,02). Essas diferenças desaparecem quando a prole atinge o estágio natante com ambos os pais permanecendo próximos aos filhotes (p = 0,98). Entretanto, há uma redução na frequência de ameaças emitidas pelos machos (p<0,01) e um aumento na frequência de ataques emitidos pelas fêmeas nessa fase (p<0,01), o que poderia ser uma resposta ao aumento da demanda por defesa da prole. Nossos resultados indicam que a cooperação reprodutiva entre machos e fêmeas de L. araguaiae é representada pela divisão de funções nas primeiras fases reprodutivas, seguida pelo compartilhamento de tarefas parentais à medida que a prole se desenvolve.
