Determination of Artificial Incubation Time of Some Malawi Cichlid Species Incubating in the Mouth (Iodotropheus sprengerae, Cyrtocara moorii, Maylandia estherae, Labidochromis caeruleus) Eggs

Acta Natura et Scientia, 2020
Malawi cichlid species belonging to the Cichlidae family are among the most popular commercial species in the aquarium industry. Females of this species begin to incubate their eggs in the mouth after ovulation. Professional producers continue to induce

Freshwater hydrozoan blooms alter activity and behaviour of territorial cichlids in Lake Tanganyika [PDF]

Royal Society Open Science, 2019
Blooms of gelatinous zooplankton can represent dramatic environmental perturbations for aquatic ecosystems. Yet, we still know little about how blooms impact fitness-related behaviours of fish caught within their areas of effect, especially for ...

The Early Development of the Blue-Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae). [PDF]

Evol Dev
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...

Phylogenomics of trophically diverse cichlids disentangles processes driving adaptive radiation and repeated trophic transitions

Ecology and Evolution, 2022
Cichlid fishes of the tribe Tropheini are a striking case of adaptive radiation, exemplifying multiple trophic transitions between herbivory and carnivory occurring in sympatry with other established cichlid lineages. Tropheini evolved highly specialized

Identification of a novel sex determining chromosome in cichlid fishes that acts as XY or ZW in different lineages

Hydrobiologia, 2021
Sex determination systems are highly conserved among most vertebrates with genetic sex determination, but can be variable and evolve rapidly in some. Here, we study sex determination in a clade with exceptionally high sex chromosome turnover rates.

Diversity in visual sensitivity across Neotropical cichlid fishes via differential expression and intraretinal variation of opsin genes

Molecular Ecology, 2021
The visual system of vertebrates has greatly contributed to our understanding of how different molecular mechanisms shape adaptive phenotypic diversity.

Manipulation of the Tyrosinase gene permits improved CRISPR/Cas editing and neural imaging in cichlid fish

Scientific Reports, 2021
Direct tests of gene function have historically been performed in a limited number of model organisms. The CRISPR/Cas system is species-agnostic, offering the ability to manipulate genes in a range of models, enabling insights into evolution, development,

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

Biology, 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.

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 ...
