Mesoscale Oceanographic Processes Drive the Seasonal Abundance of the Seabob Shrimp Xiphopenaeus spp. on the Eastern Brazilian Shelf

Fisheries Oceanography, EarlyView.
ABSTRACT The seabob shrimp (Xiphopenaeus spp.) is a primary fishery resource in Brazil, with considerable economic and social importance along the coast. While environmental drivers of its life cycle are well‐documented for southeastern and southern populations, the factors modulating populations in the Eastern Brazilian Shelf remain poorly understood,

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Evaluating a multispectral miniaturised fluorometer with three excitation channels for predicting phytoplankton community structure indices from BGC-Argo float observations [PDF]

Biogeosciences
Phytoplankton community composition is a key determinant of ocean biogeochemical cycles, yet its observation from autonomous platforms remains challenging. In this study, we assessed the potential of in situ multispectral excitation fluorescence (MXF) to

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Trophic niche overlap between native and non‐native fishes in central Anatolian lakes, Türkiye

Journal of Fish Biology, EarlyView.
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, EarlyView.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with
