Interannual Variability of Yellowfin Tuna (Thunnus albacares) and Bigeye Tuna (Thunnus obesus) Catches in the Southwestern Tropical Indian Ocean and Its Relationship to Climate Variability

Frontiers in Marine Science, 2022
This study investigated the interannual variability of yellowfin tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus) catches in the southwestern tropical Indian Ocean (SWTIO) over 25 years and its relationship to climate variability.

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.

Is Blood Thicker Than Water? The Influence of Kin Within a Bull Shark Social Network

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how kinship (“kinfluence”) shapes social structure in an aggregation of adult bull sharks in Fiji by integrating genomic relatedness, pedigree reconstruction, and detailed behavioral data. It reveals that while genetic relatedness has a small but significant influence on social behavior, especially among males, kin‐category ...

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology, Volume 33, Issue 4, Page 733-743, August 2026.
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

Tuna Species Substitution in the Spanish Commercial Chain: A Knock-On Effect.

PLoS ONE, 2017
Intentional mislabelling of seafood is a widespread problem, particularly with high-value species like tuna. In this study we examine tuna mislabelling, deliberate species substitution, types of substitution and its impact on prices.

Biodiversity in the bycatch community of Chinese tuna longline fisheries in the Pacific Ocean

Global Ecology and Conservation, 2020
The biodiversity of the bycatch community in tuna longline fisheries has historically been under-studied. In this study, observer data from 9744 sets of Chinese tuna longline fisheries were used to estimate the biodiversity of the bycatch by applying ...

Genetic evidence for inter-oceanic subdivision of bigeye tuna ( Thunnus obesus ) populations

Marine Biology, 1998
Bigeye tuna (Thunnus obesus Lowe, 1839) are a commercially important species of tuna found in the Atlantic, Indian, and Pacific oceans. To initiate an analysis of bigeye tuna population-structure, three PCR–RFLP assays were developed based on the published mtDNA control-region sequences of four bigeye tuna.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, Volume 109, Issue 1, Page 400-449, July 2026.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...
