AI-powered underwater imaging reveals multiscale occurrence and volume-based abundance patterns in coastal fishes

Ignacio A. Catalán, Amaya Álvarez-Ellacuría, José-Luis Lisani, Josep Sánchez et autres

Long-term, high-frequency monitoring is increasingly required to detect ecological change in human-impacted coastal zones, yet fixed underwater imaging commonly produces relative counts that are difficult to standardize across time and sites. We analyzed a nine-year (2016–2024) time series from a cabled fixed …

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Myron A. Peck, Ignacio A. Catalán, Ryan R. Rykaczewski, Akinori Takasuka et autres

ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources …

An Angler‐Friendly AI Pipeline for Self‐Reporting and Automatic Catch Analysis in Recreational Fisheries

Marco Signaroli, Bernat Morro, Eugenio Cutolo, Ignacio A. Catalán et autres

ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into …

Inferring activity patterns of aquatic animals from single‐receiver acoustic telemetry setups

Eneko Aspillaga, Josep Alós, Ignacio A. Catalán, Vicenç Moltó et autres

Abstract Acoustic telemetry has become an essential tool for studying activity patterns of animals in aquatic environments. Activity is typically recorded using transmitters with integrated sensors or dense receiver arrays for positional tracking. While effective, these approaches are financially and logistically expensive …

Behavioural types correlate with the gut microbiome in juvenile wild and reared gilthead seabream

Aina Pons Salom, Eneko Aspillaga, Ignacio A. Catalán, Tomeu Viver et autres

The gut microbiome influences host behaviour through the gut–brain axis (GBA), a bidirectional network of signalling pathways. Although the GBA has been well studied in humans and other mammals, its role in shaping individual behavioural variation in fish remains largely unexplored. In …
