No Population Structure of Bigeye Tunas (Thunnus obesus) in the Western and Central Pacific Ocean Indicated by Single Nucleotide Polymorphisms

Frontiers in Marine Science, 2022
The current management of the bigeye tuna (Thunnus obesus) fishery in the Western and Central Pacific Ocean (WCPO) is based on a “single-stock” paradigm.

Towards acoustic discrimination of tropical tuna associated with Fish Aggregating Devices.

PLoS ONE, 2019
Tropical tuna support some of the largest and most valuable artisanal and industrial fisheries worldwide, conducted to a large degree with Fish Aggregating Devices (FADs).

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

Journal 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 ...

Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...

Impacts of phytoplankton availability on bigeye tuna (Thunnus obesus) recruitment in the Indian Ocean

Frontiers in Marine Science
IntroductionA sustainable fishery relies on consistent and substantial recruitment. There is, however, considerably high mortality among fish larvae during their early development. One of the most important factors determining larval survival is foraging

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

Journal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Heat exchange rates between adult sockeye salmon (Oncorhynchus nerka) and the environment

Journal of Fish Biology, EarlyView.
Abstract Body temperatures of salmon do not always match the temperatures of their immediate environment. We investigated the relationship between varying ambient water temperatures and body temperatures of adult sockeye salmon Oncorhynchus nerka using Newton's law of cooling and non‐linear mixed models.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, Volume 4, Issue 3, Page 278-292, August 2026.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...
