Testes of MP were composed of 50% of spermatozoa, whereas spermatogonia type B and spermatocytes were predominant in the subsequent parental phases. They are tolerant of low dissolved oxygen that may kill most other species (Staeck and Linke 1995) and have been observed dispersing through extremely shallow water at the beginning of the rainy season (Sucksdorff 1981, in Kullander 1983).

US Fish and Wildlife Service Ecological Risk Screening Summary for. The caudal fins of C. dimerus are characterized as having a web-like pattern of dark bands and caudal rays with the clear spaces between the rays and bands being larger in the upper caudal than the lower caudal fin; by contrast, the caudal fins of C. bimaculatum have pale bands and the appearance of a symmetrical dotted pattern (Robins et al. No differences were observed in estradiol and cortisol levels among the different phases. Hence, C. dimerus males showed important changes in its hormonal profiles and testicular cellular composition throughout the reproductive and parental care period.

Forming pairs, C. dimerus defends territories in which they spawn; eggs are laid on cleaned substrate and fry are moved by mouth into pits (Pandolfi et al. 1974. In this study, we analyzed gene expression profiles, plasma steroids concentrations, and gonadal morphology throughout the reproductive cycle of female Cichlasoma dimerus (Heckel, 1840), a monogamous cichlid fish exhibiting social hierarchies.

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. Cichlasoma dimerus engages in biparental care of the fry. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information.
