Diverse prey capture strategies in teleost larvae [PDF]

eLife
Animal behavior is adapted to the sensory environment in which it evolved, while also being constrained by physical limits, evolutionary history, and developmental trajectories. The hunting behavior of larval zebrafish (Danio rerio), a cyprinid native to

The genomic timeline of cichlid fish diversification across continents

Nature Communications, 2020
Cichlids are a model for adaptive radiation, but the timing of their diversification is debated. Here the authors assemble 14 cichlid genomes, introduce a Bayesian approach to account for fossil-assignment uncertainty, and present a dated phylogenomic ...

Dynamic co-evolution of transposable elements and the piRNA pathway in African cichlid fishes [PDF]

Genome Biology
Background East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown.

GROWTH OF Geophagus brasiliensis REARED AT DIFFERENT TEMPERATURES AND FEEDING REGIMES

Boletim do Instituto de Pesca, 2021
The aim of this study was to evaluate the growth performance of Geophagus brasiliensis rearedb under distinct temperatures (24.3 ± 0.9, 28.1 ± 1.0, and 31.7 ± 0.8°C) and feeding regimes (apparent satiety and a supply of 4% of the total biomass).

Salinized water as a strategy for increase stocking density in Heros severus larviculture, an Amazonian ornamental fish

Boletim do Instituto de Pesca, 2023
The aim of this study was to evaluate the effect of different salinized water (0, 3 and 6 g L-1) and stocking densities (10, 15 and 20 larvae L-1) in Heros severus larviculture.

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 ...

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

The evolution of monogamy in cichlids and marine reef fishes

Frontiers in Ecology and Evolution, 2022
Although several hypotheses have been proposed to explain the emergence of social monogamy, its origin is still intensely debated. Monogamy has many potential drivers, but evolutionary causality among them remains unclear.

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

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.
