Aggressive behavior and reproductive physiology in females of the social cichlid fish Cichlasoma dimerus.
The South American cichlid fish Cichlasoma dimerus is a freshwater species that presents social hierarchies, a highly organized breeding activity, biparental care and a high frequency of spawning. Spawning is followed by a period of parental care (about 20 days in aquaria conditions) during which the cooperative pair takes care of the eggs, both by fanning them and by removing dead ones. The di...
متن کاملSocial and reproductive physiology and behavior of the Neotropical cichlid fish Cichlasoma dimerus under laboratory conditions
In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral approach, including morphological and physiological features. This substrate breeding fish has biparental care of the fry and presents a dominance hierarchy that dete...
متن کاملPhotoperiodic modulation of reproductive physiology and behaviour in the cichlid fish Cichlasoma dimerus.
Timing of breeding to an optimal season is a requirement for a successful reproductive outcome in seasonally breeding species. Photoperiodic signals are capable of modifying the reproductive behaviour and reproductive systems in several vertebrate species. The cichlid fish Cichlasoma dimerus shows highly organized breeding activities and different social status. The aim of this study is to test...

the zebra cichlid cichlasoma nigrofasciatum is a species famous for its behaviors of biparental care. this study was conducted to examine the effect of parental care and their size on the reproductive success of this fish. hatching rate (hrs) has significant difference (p
متن کاملPopulation Dynamics of Cyanomyovirus in a Tropical Eutrophic Reservoir
Samples from three stations in Kranji Reservoir, Singapore (n = 21) were collected and analyzed for cyanomyovirus abundance and diversity. A total of 73 different g20 (viral capsid assembly protein genes) amino acid sequences were obtained from this study. A phylogenetic analysis revealed that the 73 segments were distributed in six major clusters (α to ζ), with four unique subclusters, which w...
