The presence of Atlantic bluefin tuna in northern European seas is driven by climate variability and ocean temperature.
Through the advancement of observation systems, our vision has far extended its reach into world fishes, and how they interact with fishing gears—breaking through physical boundaries visually adapting to challenging conditions in marine environments. As sciences step era artificial intelligence (AI), deep learning models now provide tools for researchers process a large amount imagery data (i.e., image sequence, video) on fish behavior more time-efficient cost-effective manner. The latest AI...
Most demersal fishes undergo a dispersal phase as larvae, which strongly influences the connectivity among adult populations and, consequently, their genetic structure and replenishment opportunities. Because this is difficult to observe directly, it frequently simulated through numerical models, most of consider larvae passive or only vertically migrating. However, in several locations, including Mediterranean Sea, many species have been shown swim fast orient. Here we use Lagrangian model...
For over two centuries, trawling fisheries have operated blindly; catches could not be known until onboard. These activities, which represents half of seafood protein supply and fishermen incomes, worldwide, are facing increasing societal pressure for their impacts on the ecosystem greenhouse gas emissions. Yet as today, no alternative exists to maintain same levels production while reducing species welfare ecosystems. We here demonstrate that previously blind activities can now turned into...
Abstract Infrared (IR) light is widely accepted as a non‐intrusive lighting for discreet observation but relevant studies are scarce. The response of European seabass Dicentrarchus labrax (Linnaeus 1758) towards IR was tested during laboratory experiments alternating sequences and dark conditions. Swimming trajectories were extracted from hydroacoustic videos behavioural metrics (e.g. speed, bearings) quantified the D. movement patterns. showed no preference nor deterrence light, supporting...
The 2010 Deepwater Horizon (DWH) oil well blowout in the Gulf of Mexico (GoM) was largest and perhaps most consequential accidental marine spill global history. This paper provides an overview a Research Topic consisting four additional papers that: (1) assemble time series data for ecosystem components regions impacted by spill, (2) interpret temporal changes related to vulnerability species ecosystems DWH ensuing resilience perturbation. Time abundance many taxa pre-date DWH, often...
Tracking and classifying fish in optical underwater imagery presents several challenges which are encountered less frequently terrestrial domains. Video may contain large schools comprised of many individuals, dynamic natural backgrounds, highly variable target scales, volatile collection conditions, non-fish moving confusers including debris, marine snow, other organisms. Additionally, there is a lack public datasets for algorithm evaluation available this domain. The contributions paper...
Abstract Historically, the mortality of early‐life stages marine fishes was supposed to be mostly caused by poor feeding during a critical period and aberrant drifting away from favorable recruitment areas. While fish larvae may display remarkable swimming abilities, Hjort's drift hypothesis has rarely been tested. In this study, we measured speed ( U crit ) settlement‐stage six coastal, warm temperate Mediterranean species, for which no data were previously available (Sparidae: Boops boops...
Mortality is very high during the pelagic larval phase of fishes but factors that determine recruitment success remain unclear and hard to predict. Because their bipartite life history, larvae coastal species have head back shore at end episode, settle. These settlement-stage are known display strong sensory motile abilities, most work has been focused on tropical, insular environments influence coast-related cues orientation. In this study we quantified in situ orientation behavior a...
After the Deepwater Horizon oil platform explosion, an estimated 172.2 million gallons of gas-saturated was discharged uncontrollably into Gulf Mexico, causing largest deep-sea blowout in history. In attempt to keep submerged, massive quantities chemical dispersant Corexit® 9500 were deployed 1522m deep at gushing riser pipe Macondo prospect's wellhead. Understanding effectiveness this unprecedented Sub-Sea Dispersant Injection (SSDI) is critical because deep-water drilling increasing...
Abstract Low-impact fishing gear, such as fish pots, could help reduce human’s impact on coastal marine ecosystems in fisheries but catch rates remain low and the harvest of resources used for baiting increases their environmental cost. Using black seabreams ( Spondyliosoma cantharus ) target species Bay Biscay, we developed assessed efficiency biodegradable biopolymer-based baits (hereafter bio-baits) made cockles Cerastoderma edule different biopolymer concentrations. Through a suite deep...
During the Deepwater Horizon (DWH) blowout, photooxidation of surface oil led to formation persistent photooxidized compounds, still found in shoreline sediments a decade later. Studies demonstrated that modified both biodegradation rates and effectiveness aerial dispersant applications. Despite significant consequences this weathering pathway, lack measurements prevented be accounted for DWH budget calculations most predictive models. Here we develop Lagrangian module estimates dose solar...
Identifying complex behaviors such as spawning and fine-scale activity is extremely challenging in highly migratory fish species becoming increasingly critical knowledge for fisheries management a warming ocean. Habitat use pathways have been extensively studied marine animals using pop-up satellite archival tags (PSATs), but high-frequency data collected on the reproductive swimming of fishes has limited by inability to remotely transmit these large datasets. Here, we present first...
Most coastal fish species spend their early life stages in the pelagic environment, before settling habitats. The variability arrival of larvae to habitats provides information on species’ biology and recruitment potential. To explore dynamics larval supply NW Mediterranean Sea, 13 sites were monitored using light-traps, from July 2012 December 2015. variation catches per unit effort (CPUE) among topographic basins statistically significant for high (quantile 75%) very 90%) only. At yearly...
Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations these are often scattered space and time. While Mediterranean coastlines have been surveyed, no effort has made assemble historical observations. Here we build an exhaustive compilation dispersal traits for coastal species, considering situ growth models (Di Stefano et al., 2023; https://doi.org/10.17882/91148). Our database contains over 110 000...
The Deepwater Horizon (DWH) disaster released 3.19 million barrels of crude oil into the Gulf Mexico (GOM) in 2010, overlapping habitat pelagic fish populations. Using mahi-mahi (Coryphaena hippurus)─a highly migratory marine teleost present GOM during spill─as a model species, laboratory experiments demonstrate injuries to physiology and behavior following exposure. However, more than decade postspill, impacts on wild populations remain unknown. To address this gap, we exposed or control...

The French fishing industry is becoming increasingly environmentally aware and likely to adopt more sustainable gears. As a result, fishers are showing growing interest in fish pots. This experiment aimed develop pot concept specifically based on target species behavior coastal waters. First, the consultation led with indicated black seabream as main of interest. Then, pot’s characteristics were defined comply regulations. conception process was step-by-step by gradually testing design...
