Effects of different sampling intervals on apparent protein and energy digestibility of common feed ingredients by juvenile oscar fish (Astronotus ocellatus)=Diferentes intervalos de coleta na determinação da digestibilidade aparente da proteína e da energia de ingredientes comuns para o apaiari (Astronotus ocellatus) [PDF]
Acta Scientiarum: Animal Sciences, 2012 This study evaluated the apparent protein and energy digestibility of common feed ingredients (soybean meal, fish meal, wheat meal and corn) by juvenile oscars using two different sampling intervals (30 min. and 12h).

Genome editing in East African cichlids and tilapias: state-of-the-art and future directions
Open Biology, 2023 African cichlid fishes of the Cichlidae family are a group of teleosts important for aquaculture and research. A thriving research community is particularly interested in the cichlid radiations of the East African Great Lakes. One key goal is to pinpoint

Genome-wide protein phylogenies for four African cichlid species
BMC Evolutionary Biology, 2018 Background The thousands of species of closely related cichlid fishes in the great lakes of East Africa are a powerful model for understanding speciation and the genetic basis of trait variation.

Ecology and Evolution, 2021 Cichlids inhabiting the Great Lakes of Africa have radiated extremely rapidly, with Lake Malaŵi harboring some 850 species. This rapid radiation may be linked to the diversity in behaviors, sexual selection, and phenotypic plasticity.

Introduced predator elicits deficient brood defence behaviour in a crater lake fish. [PDF]
PLoS ONE, 2012 Introduced species represent one of the most serious global threats to biodiversity. In this field-based study, we assessed behavioural responses of brood tending cichlid fish to an invasive predator of their offspring.

Gene coexpression networks reveal molecular interactions underlying cichlid jaw modularity
BMC Ecology and Evolution, 2021 Background The oral and pharyngeal jaw of cichlid fishes are a classic example of evolutionary modularity as their functional decoupling boosted trophic diversification and contributed to the success of cichlid adaptive radiations. Most studies until now

Croatian Journal of Fisheries, 2016 Coptodon walteri Thys van den Audenaerde 1968, an endemic cichlid of Ivory Coast and Liberia, is assessed as Near Threatened due to fishing pressure and loss of habitats, and aquatic pollution as a result of extensive clandestine gold mining in the bed ...

Early stages of sympatric homoploid hybrid speciation in crater lake cichlid fishes
Nature Communications, 2022 Here, the authors present a rare example of sympatric homoploid hybrid speciation, without ploidy changes, in the Midas cichlid fishes from Nicaragua. Midas cichlid hybrids occupy a different ecological niche, likely facilitated by body shape adaptations.
