Photoresponses of tilapia melanophores.

open access: yes, 2013
Individual melanophores were challenged with equal-quanta spectral irradiance (13.9 log photons cm−2 s−1) at one of the stimulating wavelengths (A,B: 380 nm; C,D: 420 nm; E,F: 460 nm; G,H: 500 nm; I,J: 540 nm; K,L: 580 nm; n = 4 at each test wavelength ...

Taisho-Sanshoku koi have hardly faded skin and show attenuated melanophore sensitivity to adrenaline and melanin-concentrating hormone

open access: yesFrontiers in Endocrinology, 2022
IntroductionKoi carp, an ornamental fish derived from the common carp Cyprinus carpio (CC), is characterized by beautiful skin color patterns. However, the mechanism that gives rise to the characteristic vivid skin coloration of koi carp has not been ...

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

open access: yesJournal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Evolution of Endothelin signaling and diversification of adult pigment pattern in Danio fishes. [PDF]

open access: yesPLoS Genetics, 2018
Fishes of the genus Danio exhibit diverse pigment patterns that serve as useful models for understanding the genes and cell behaviors underlying the evolution of adult form. Among these species, zebrafish D.

Early and Larval Development of the Marine Species Grey Triggerfish (Balistes capriscus, Gmelin, 1789) and the Use of Different Organisms as First Food Sources

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The aim of this study was to provide an initial description of the embryology and larval development of Balistes capriscus species obtained from natural spawning in captivity. The study also aimed to assess the stocking density and the impact of offering four types of live food as the initial feed during the larviculture phase. Observations of

Zebrafish Embryos to Profile Nano(bio)materials: A Modular Platform for Developmental Toxicity, Neurotoxicity, and Inflammation‐Regeneration Assays

open access: yesCurrent Protocols, Volume 6, Issue 6, June 2026.
Abstract Zebrafish embryos provide a rapid, low‐cost in vivo platform to profile the developmental, neurotoxic, and immunomodulatory effects of engineered nano(bio)materials within a single vertebrate system. This article presents a modular workflow that integrates standardized fish embryo acute toxicity (FET) testing, chemically assisted ...
