“…Previous studies showed that the total length of females of H. malabaricus at first reproduction could vary from 141.0 mm (Oliveira & Nogueira, 2000) to 230.0 mm (Barbieri, 1989), the mean diameter of mature oocytes was 1.75 mm, and the number of mature oocytes could vary from 6,446 to 14,131 (Araújo-Lima & Bittencourt, 2001). These values differ from those recorded for the species in the present study.…”

“…As observed in the present study, in central Amazonia the yellowish eggs are also deposited in shallow water (~ 15 cm deep), close to aquatic vegetation, in saucer-format nests, forming an adherent mass of eggs (Araújo-Lima & Bittencourt, 2001); eggs are adhered to each other due to the presence of a specific glicoprotein (Matkovic & Pisanó, 1989c). Previous studies showed that the total length of females of H. malabaricus at first reproduction could vary from 141.0 mm (Oliveira & Nogueira, 2000) to 230.0 mm (Barbieri, 1989), the mean diameter of mature oocytes was 1.75 mm, and the number of mature oocytes could vary from 6,446 to 14,131 (Araújo-Lima & Bittencourt, 2001).…”

“…The Erythrinidae family is distinguished by showing male parental care of eggs (Blumer, 1982), but the author did not cite the species presenting male parental care. Moreover, in prior studies on H. malabaricus it is not clear which parent provides parental care (Caramaschi & Godinho, 1982;Machado-Allison, 1990;Araújo-Lima & Bittencourt, 2001). Thus, this study is the first to describe parental care in detail for H. malabaricus.…”

“…Individuals are generally found in pools (amidst the marginal vegetation), are cryptically colored, and capture prey by ambush (Uieda, 1984;Casatti et al, 2001). Furthermore, H. malabaricus shows multiple spawning and parental care (Caramaschi & Godinho 1982;Araújo-Lima & Bittencourt, 2001). However, previous studies do not report which sex is responsible for the care in H. malabaricus.…”

Herein we describe spawning and egg guarding in the erythrinid fish Hoplias malabaricus observed in the southern Pantanal (19° 34' S and 57° 00' W), state of Mato Grosso do Sul, Brazil. Nests were depressions built on sandy soil in flooded areas, and contained a mean of 8,197 ± 2,204 eggs (N = 4); the mean diameter of eggs was 1.44 ± 0.09 mm (N = 400). Among 11 nests observed, eight were guarded by males and three by the pair. One male remained in the nest for six days, and two pairs remained guarding the eggs for at least three days before being captured. Females (N = 2) captured in the nest contained oocytes in their ovaries. Our observations suggest that male parental care is the normal form of parental care in H. malabaricus, but biparental care also seems to occur. No presente estudo, descrevemos os comportamentos de desova e cuidado parental para um membro da referida família, Hoplias malabaricus, os quais foram observados no Pantanal sul (19° 34' S e 57° 00' W), Estado de Mato Grosso do Sul, Brasil. As desovas foram observadas no início da cheia, depositadas em ninhos construídos em substrato arenoso em áreas alagadas. As desovas continham, em média, 8.197 ± 2.204 ovos (N = 4); o diâmetro médio dos ovos foi de 1,44 ± 0,09 mm (N = 400). Entre 11 ninhos observados, oito foram guardados por machos e em três observamos o casal. Um macho permaneceu no ninho por seis dias, e dois casais foram observados por três dias no ninho até serem capturados. As fêmeas (N = 2) capturadas nos ninhos continham óvulos nos ovários. O cuidado parental em Hoplias malabaricus é normalmente exercido pelos machos, mas nossas observações sugerem que o cuidado biparental pode ocorrer de forma facultativa.Palavras-chave: reprodução, cuidado parental, Hoplias malabaricus, Erythrinidae, Pantanal.

“…In addition, low water velocities favor reproduction of H. aff. Malabaricus, which prefers lentic and muddy waters for spawning (Araújo-Lima & Bittencourt, 2001;Nakatani et al, 2001) as well as T. rendalli (Fialho & Tejerina-Garro, 2004;Oliveira & Bennemann, 2005).…”

The Ouvidor River, a tributary of the Upper Paraná River, drains areas covered by cerrado vegetation in Central Brazil. We collected data for environmental variables (water temperature, dissolved oxygen, pH, conductivity, turbidity, water velocity, luminosity, channel substrate and width) and anthropogenic perturbations (industry, reservoirs, urban areas) that may structure the fish assemblage in ten stream sites of the Ouvidor River basin. In each stream we delimited one 50 m long site where fish were captured by electrofishing and abiotic data were collected every two month between August 2004 and June 2005. Coinertia analysis indicated that pH, water velocity, channel width and water temperature most strongly structured the fish assemblages. The interactions of water velocity and channel width with the fish assemblage were not directly affected by wet and dry seasons but the opposite was true for pH and water temperature.O rio Ouvidor é um tributário do Alto rio Paraná, Brasil Central, que drena áreas cobertas por vegetação do tipo Cerrado. Em dez cursos d'água da bacia do referido rio foram coletados dados referentes às variáveis ambientais (temperatura de água, oxigênio dissolvido, pH, condutividade, turbidez, velocidade da água, luminosidade, substrato do canal e largura) e perturbações antropogênicas (indústria, represas, área urbana) que poderiam estruturar as assembléias de peixes. Em cada curso d'água foi delimitada uma estação de 50 m de comprimento, onde bimestralmente entre agosto de 2004 e junho de 2005 os peixes foram capturados utilizando-se a pesca elétrica e coletados os dados abióticos. A análise de co-inércia indicou que o pH, a velocidade da água, a largura do canal e a temperatura da água são os fatores que mais fortemente estruturaram as assembléias de peixes. A interação da velocidade da água e a largura do canal com as assembléias de peixes não foram afetadas diretamente pelo regime hidrológico regional (chuva e estiagem), enquanto que o contrário é observado para as variáveis pH e temperatura da água.

Species of Melanorivulus present behaviour and physiological traits that allow them to live in marginal aquatic habitats. In particular, Melanorivulus rossoi is a small nonannual fish only known from its type locality in the Brazilian Cerrado. In this study, we aimed to characterize the distribution and temporal variation in body size, sex ratio, density, length-weight relationship (LWR) and condition factor (CF) of M. rossoi in its natural habitat. To accomplish this, fish samples were taken monthly for a year using sieve nets every 30 min. Body size of males and females increased throughout the year until early summer. LWR was significant, and general coefficient of determination (r 2) was 92%. Juveniles showed negative allometric growth, but adults showed positive allometric growth. Both sexes presented the same tendency of temporal variation in CF, with lower values in October and January and peaks in September and February. Fire occurred in June, but no difference in population parameters was observed after this event. A decrease in the abundance of Melanorivulus was related with an increase in the abundance of Erythrinidae juveniles. This might be explained by an increased predation of this species over the M. rossoi individuals, when the population was reduced to about 30% of that in the previous months. We report four new locations where this species was recorded; thus, similar to most Rivulidae members, M. rossoi has a restricted distribution area and is threatened with extinction. Therefore, our results may be useful in developing management strategies aimed at conservation of this species and its habitat in Brazil.
