Cichlid genome modification - Malawi cichlids v1

, 2023
Here we provide a microinjection protocol for the modification of cichlid fish via CRISPR or transgenesis. This is our forked version of the protocol provided by Scott Juntti (https://www.protocols.io/view/cichlid-genome-modification-cj5wuq7e), modified for our Lake Malawi cichlid species for both NHEJ knock-outs and HDR knock-ins These protocols ...

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.

Molecular and fossil evidence place the origin of cichlid fishes long after Gondwanan rifting. [PDF]

, 2013
Cichlid fishes are a key model system in the study of adaptive radiation, speciation and evolutionary developmental biology. More than 1600 cichlid species inhabit freshwater and marginal marine environments across several southern landmasses.

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

Gene duplication in an African cichlid adaptive radiation [PDF]

, 2014
Background Gene duplication is a source of evolutionary innovation and can contribute to the divergence of lineages; however, the relative importance of this process remains to be determined.

Invasive cichlids (Teleostei: Cichliformes) in the Amacuzac River, Mexico: Implications for the behavioral ecology of the native Mexican mojarra Amphilophus istlanus

Water Biology and Security, 2023
The introduction of species is a leading cause of biodiversity loss and habitat alteration. Several species have invaded Mexican freshwater ecosystems, adversely affecting native fishes.
