Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Genes, fish and fisheries: translating science into policy

open access: yesJournal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Migration dynamics of juvenile southern bluefin tuna [PDF]

open access: yesScientific Reports, 2018
AbstractLarge scale migrations are a key component of the life history of many marine species. We quantified the annual migration cycle of juvenile southern bluefin tuna (Thunnus maccoyii; SBT) and spatiotemporal variability in this cycle, based on a multi-decadal electronic tagging dataset.

Securing Long‐Chain Omega‐3 Fatty Acid Supply for Sustainable Aquaculture Development and Human Nutrition

open access: yesReviews in Aquaculture, Volume 19, Issue 1, January 2027.
Omega‐3 LC‐PUFA lie at the intersection of aquaculture performance and human nutrition. Deployment of w3 LC‐PUFA rich microalgal oils derived from low trophic levels offers credible long‐term sustainable solutions, taking full account of the potential environmental footprints and benefits in terms of human nutrition and health.

Functional Morphology of the Inner Ear of Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei): Adaptations for Hearing Within a Pelagic Environment

open access: yesJournal of Comparative Neurology, Volume 534, Issue 11, November 2026.
In this article, we provide the first extensive neuroanatomical characterization of the inner ear of southern bluefin tuna, using scanning electron microscopy. Morphological results include six distinct hair cell orientation groups in the saccule, partial otolith coverage in the lagena and the utricle, and presence of a high density of hair cells with ...
