pnp4a Is the Causal Gene of the Medaka Iridophore Mutant guanineless

G3: Genes, Genomes, Genetics, 2017
See-through medaka lines are suitable for observing internal organs throughout life. They were bred by crossing multiple color mutants. However, some of the causal genes for these mutants have not been identified.

Bar, stripe and spot development in sand-dwelling cichlids from Lake Malawi

EvoDevo, 2019
Background Melanic patterns such as horizontal stripes, vertical bars and spots are common among teleost fishes and often serve roles in camouflage or mimicry. Extensive research in the zebrafish model has shown that the development of horizontal stripes

Ultrastructure of Erythrophores and Xanthophores of the Siamese Fighting Fish, Betta splendens [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2012
The ultrastructural morphology of brightly colored pigment cells (chromatophores) of Siamese fighting fish, Betta splendens, was investigated by transmission electron microscopy. The major pigment cells in the epidermis and dermis of the red and golden strains were erythrophores and xanthophores, respectively.

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 ...

Dual Knockout Models of the Spatially and Functionally Conserved rgra and rgrb Zebrafish Genes Reveal the Requirement of RGR for the Integrity of Cone‐Mediated Photopic Vision, the Photopic Visual Cycle and Bruch's Membrane Morphology

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, Volume 82, Issue 5, Page 4661-4668, May 2026.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Comparative transcriptomics reveals candidate carotenoid color genes in an East African cichlid fish

BMC Genomics, 2020
Background Carotenoids contribute significantly to animal body coloration, including the spectacular color pattern diversity among fishes. Fish, as other animals, derive carotenoids from their diet.

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 ...
