Mechanistic modelling reveals tuna physiological condition is not a driver of floating object association Open
Assessing the proximate and ultimate causes of animal behaviour is crucial for understanding the impact of human activities on wild species. However, for animals that are difficult to observe in the wild, such as pelagic fish species, iden…
Scripts for: Mechanistic modelling reveals tuna physiological condition is not a driver of floating object association Open
These are the scripts and data used to perform the analysis in the following paper: Dupaix A, Deneubourg J-L, Forget F, Tolotti MT, Dagorn L, Capello M. (2025) Mechanistic modelling reveals tuna physiological condition is not a driver of f…

The challenge of assessing the effects of drifting fish aggregating devices on the behaviour and biology of tropical tuna Open
Fishers have intensively used drifting fish aggregating devices (DFADs) over the last three decades to facilitate their catch of tropical tunas. DFADs increase purse‐seine efficiency, potentially increasing tuna fishing mortality. They cou…
Recommendations towards the establishment of best practice standards for handling and intracoelomic implantation of data-storage and telemetry tags in tropical tunas Open
Archival (data-storage) and telemetry (acoustic and radio) tags are commonly used to provide data on the behavior and physiology of organisms, as well as data on their surrounding environment. For fishes, it is often advantageous to implan…

Diving into the vertical dimension of elasmobranch movement ecology Open
Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on…
Pop-up satellite archival tagging data of Atlantic bluefin tuna in the Gulf of Lions, Northwestern Mediterranean Sea Open
24 Atlantic bluefin tuna (Thunnus thynnus) individuals (117–158 cm fork length) were tagged with pop-up archival tags in the Gulf of Lion, NW-Mediterranean Sea between 2015 and 2016. Tag programming and data The tags applied (miniPATs by W…

Tuna behaviour at anchored FADs inferred from Local Ecological Knowledge (LEK) of pole-and-line tuna fishers in the Maldives Open
The Maldives tuna fishery landings in 2018 were 148, 000 t and accounted for nearly a quarter of the global pole-and-line tuna catch. This fishery partially relies on a network of 55 anchored fish aggregating devices (AFADs) deployed aroun…
Cardiac and behavioural responses to hypoxia and warming in free-swimming gilthead seabream, <i>Sparus aurata</i> Open
Gilthead seabream were equipped with intraperitoneal biologging tags to investigate cardiac responses to hypoxia and warming, comparing when fish were either swimming freely in a tank with conspecifics or confined to individual respiromete…
Movement behaviour and fishery interaction of silky sharks (<i>Carcharhinus falciformis</i>) in the tropical tuna purse seine fishery in the Western Indian Ocean Open
The silky shark Carcharhinus falciformis regularly associates with floating objects in the open ocean, resulting in relatively high levels of bycatch in industrial tuna purse seine fisheries using drifting fish aggregating devices (FADs). …
Behavior of skipjack (<i>Katsuwonus pelamis</i>), yellowfin (<i>Thunnus albacares</i>), and bigeye (<i>T. obsesus</i>) tunas associated with drifting fish aggregating devices (dFADs) in the Indian Ocean, assessed through acoustic telemetry Open
We investigated the associative behavior of skipjack ( Katsuwonus pelamis ), yellowfin ( Thunnus albacares ), and bigeye ( T. obsesus ) tuna within multi‐species aggregations associated with drifting fish aggregating devices (dFADs) in two…
Cardiac and behavioural responses to hypoxia and warming in free-swimming gilthead seabream <i>Sparus aurata</i> Open
Cardiac and behavioural responses to hypoxia and warming were investigated in free-swimming gilthead seabream Sparus aurata equipped with biologging tags in the peritoneal cavity. After suitable recovery in a holding tank, heart rate ( f H…
Large-scale movements and site fidelity of two bull sharks<i>Carcharhinus leucas</i>estimated from a double-tagging experiment at Réunion Island (southwest Indian Ocean) Open
Since 2011, the mean number of bites per year by bull sharks Carcharhinus leucas has increased markedly at Réunion Island. To predict areas and periods of increased risk, we need to better understand the space-use dynamics of individual sh…
Predicting bycatch hotspots in tropical tuna purse seine fisheries at the basin scale Open
Fisheries observer programs represent the most reliable way to collect data on fisheries bycatch. However, their limited coverage leads to important data gaps that preclude bycatch mitigation at the basin scale. Habitat models developed fr…
Farmed bivalve loss due to seabream predation in the French Mediterranean Prevost Lagoon Open
Bivalve predation by seabream has been observed worldwide and is a major concern for bivalve farmers. Farmed bivalve-seabream interactions must be better understood to ensure the sustainability of bivalve aquaculture. The objectives of thi…

Can drifting objects drive the movements of a vulnerable pelagic shark? Open
Juvenile silky sharks ( Carcharhinus falciformis ) regularly associate with floating objects yet the reasons driving this behaviour remain uncertain. Understanding the proportion of time that silky sharks spend associated with floating obj…
Surfacing and vertical behaviour of Atlantic bluefin tuna (Thunnus thynnus) in the Mediterranean Sea: implications for aerial surveys Open
Atlantic bluefin tuna (Thunnus thynnus) (ABFT) frequently engage in surface basking and foraging behaviour that makes them detectable from afar. This behaviour is utilized for the development of fisheries-independent abundance indices base…
