Species of Ergasilus von Nordmann, 1832 (Copepoda: Ergasilidae) from cichlid fishes in Lake Tanganyika

open access: yesParasitology, 2023
Ergasilus (von Nordmann, 1832) (Ergasilidae) is a species-rich group of parasitic copepods with a wide distribution in freshwater, marine and brackish environments. Up to now, 9 species of Ergasilus are known from cichlid fishes in Africa. In this study,

The Evolutionary Dynamics of the Mitochondrial tRNA in the Cichlid Fish Family

open access: yesBiology, 2022
The mitochondrial transfer RNA genes (tRNAs) attract more attention due to their highly dynamic and rapidly evolving nature. The current study aimed to detect and evaluate the dynamics, characteristic patterns, and variations of mitochondrial tRNAs.

Treatment of deep second-degree burns on the abdomen, thighs, and genitalia: use of tilapia skin as a xenograft [PDF]

open access: yesRevista Brasileira de Cirurgia Plástica, 2020
Tilapia skin has a non-infectious microbiota and a morphological structure similar to human skin. Phase II clinical studies, not yet published, have shown promising results in their use for the treatment of burns.

Cichlids and stingrays can add and subtract ‘one’ in the number space from one to five

open access: yesScientific Reports, 2022
The numerical understanding of cichlids and stingrays was examined regarding addition and subtraction abilities within the number space of one to five. Experiments were conducted as two-alternative forced-choice experiments, using a delayed matching to ...

Mitochondrial genome annotation and phylogenetic placement of Oreochromis andersonii and O. macrochir among the cichlids of southern Africa. [PDF]

open access: yesPLoS ONE, 2018
Genetic characterization of southern African cichlids has not received much attention. Here, we describe the mitogenome sequences and phylogenetic positioning of Oreochromis andersonii and O. macrochir among the African cichlids.

Cichlid genome modification - Malawi cichlids v1

open access: yes, 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 ...
