Goldfishing by gauge theory

open access: yes, 2006
A new solvable many-body problem of goldfish type is identified and used to revisit the connection among two different approaches to solvable dynamical systems. An isochronous variant of this model is identified and investigated.

Distribution of choline acetyltransferase (ChAT) immunoreactivity in the brain of the teleost cyprinus carpio [PDF]

open access: yes, 2018
Cholinergic systems play a role in basic cerebral functions and its dysfunction is associated with deficit in neurodegenerative disease. Mechanisms involved in human brain diseases, are often approached by using fish models, especially cyprinids, given ...

Efficient Gene Expression System in Medaka Embryos Enables Functional Characterization of nt5c1a Paralogs Involved in Inosine Monophosphate Metabolism

open access: yesgenesis, Volume 64, Issue 3, June 2026.
ABSTRACT Optimizing transient expression systems in fish embryos is crucial for rapid gene function analysis. Here, we established an efficient system in medaka (Oryzias latipes) embryos by evaluating nucleic acid type and injection site. Our results revealed that injecting the elongation factor 1αA (ef1αA) promoter‐driven plasmid into the yolk yielded

Historical Records of Tumours in New Zealand Marine Fishes

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Tumours were first described in New Zealand marine fishes in 1982 but those early records have been difficult to access and subsequently few tumours have been collected and little has been published. This review updates records of identified tumours from teleosts in the New Zealand marine environment and may encourage more work to identify background ...

Cold acclimation increases mitochondrial oxidative capacity without inducing mitochondrial uncoupling in goldfish white skeletal muscle

open access: yesBiology Open, 2012
Summary Goldfish have been used for cold acclimation studies, which have focused on changes in glycolytic and oxidative enzymes or alterations in lipid composition in skeletal muscle.

Optimal Strouhal number for swimming animals [PDF]

open access: yes, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, Volume 13, Issue 29, 22 May 2026.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

The Effect of Addition Pumpkin (Cucurbita MoschataD.) Flour in Artificial Diet to the Color Quality of Goldfish (Carrasius Auratus) [PDF]

open access: yes, 2017
The ornamental fish price is determined by the appearance of colour. Feeding naturally feed in artificial feed aimed to improve the color quality of goldfish and how long it takes to improve the color.
