Dynamic colour change predicts movement behaviour in a diadromous fish

Journal of Fish Biology, EarlyView.
Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...

Interactions with iridophores and the tissue environment required for patterning melanophores and xanthophores during zebrafish adult pigment stripe formation.

PLoS Genetics, 2013
Skin pigment patterns of vertebrates are a classic system for understanding fundamental mechanisms of morphogenesis, differentiation, and pattern formation, and recent studies of zebrafish have started to elucidate the cellular interactions and molecular

Protein Energy Malnutrition: Opportunities for Cold Plasma Technologies

Food Frontiers, Volume 7, Issue 2, March 2026.
Protein energy malnutrition (PEM) is a major global health concern driven by biological, environmental, and nutritional factors, including gut microbiota imbalance and low protein intake. Cold atmospheric plasma technologies offer promising, sustainable solutions by improving food security, enhancing protein quality and absorption, and modulating gut ...

Sequential actions of Pax3 and Pax7 drive xanthophore development in zebrafish neural crest

Developmental Biology, 2008
The Pax3/7 gene family has a fundamental and conserved role during neural crest formation. In people, PAX3 mutation causes Waardenburg syndrome, and murine Pax3 is essential for pigment formation. However, it is unclear exactly how Pax3 functions within the neural crest.

The Early Development of the Blue‐Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae)

Evolution &Development, Volume 27, Issue 4, December 2025.
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 ...

Individual identification of bony fishes using unique body markings: Implications and applications

Journal of Fish Biology, Volume 107, Issue 6, Page 1852-1867, December 2025.
Abstract The natural variation in animal body markings, such as spots, stripes and blotches, offers a powerful tool for researchers, conservationists, citizen scientists and resource managers to distinguish specific individuals within species. By building libraries of photo‐identified individuals, we can track and differentiate individuals over time ...

Pigment cell interactions and differential xanthophore recruitment underlying zebrafish stripe reiteration and Danio pattern evolution [PDF]

Nature Communications, 2014
Fishes have diverse pigment patterns, yet mechanisms of pattern evolution remain poorly understood. In zebrafish, Danio rerio, pigment-cell autonomous interactions generate dark stripes of melanophores that alternate with light interstripes of xanthophores and iridophores. Here, we identify mechanisms underlying the evolution of a uniform pattern in D.

Bdh1l Gene Expression Is a Potential Molecular Factor in the Evolution of Carotenoid‐Based Colour Diversity of Cichlid Fishes

Molecular Ecology, Volume 34, Issue 18, September 2025.
ABSTRACT Carotenoids contribute substantially to animal body colour pattern diversity. While the ecological and evolutionary drivers of carotenoid coloration are reasonably well understood, the molecular mechanisms facilitating evolutionary transitions between red and yellow hues are less investigated.

Image‐Based Individual Fish Identification as a Substitute for Invasive Methods: State‐of‐the‐Art and Research Gaps

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Individual identification of fish within the same species is one of the most crucial and frequently performed tasks in aquaculture research, and it is also widely used in aquaculture production. Fish sampling, treating, welfare, and disease state estimation are increasingly turning from group‐based to individualized.

Transcriptome Analysis of Natural Albino Northern Snakehead (Channa argus var.) Provides Novel Insights into Color-Related Genes

Fishes
The northern snakehead (Channa argus) is an important economic fish species that holds a significant position in Chinese aquaculture due to its high nutritional value, fast growth, and anti-hypoxia capacity. There is a natural albino-mutant (AM) C. argus
