The catch of the day: The shortcomings of promoting sustainable seafood consumption in Peru

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
This study investigates the meaning and application of “catch of the day” in Peru by analyzing 233 news articles and genetically testing 43 fish samples from restaurants. Results show that media frequently use the term as a vague marketing phrase, while genetic testing reveals a 60% mislabeling rate. These findings suggest that “catch of the day” lacks

Dietary Probiotics Improve Growth, Immunity and Disease Resistance in Fish Against Aeromonas hydrophila Infection

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Probiotics offer a promising alternative to antibiotics for managing Aeromonas hydrophila infections in aquaculture. Dietary supplementation of probiotics increases fish health, growth performance, and immune responses, while reducing antibiotic reliance in fish farming.

Feeding of juvenile pirarucu (Arapaima gigas, Arapaimidae) in their natural environment, lago Quatro Bocas, Araguaiana-MT, Brazil

Neotropical Ichthyology
The stomach content of samples of juvenile Arapaima gigas was analized to obtain information about feeding in natural environments. This species occurs in the Amazonian basin, predominantly in floodplain environment. This is the case of the valley of the

Productive performance of Arapaima gigas in temperate climate ponds

Revista de Investigaciones Veterinarias del Perú, 2023
The study monitored the productive performance of the paiche (Arapaima gigas) for 30 months under temperate climate conditions on the Central Coast of Peru. After 40 days of acclimatization and with 80% survival, the fish (n: 32, weight: 44 ± 34 g, length: 17.6 ± 4.9 cm) were transferred to a greenhouse pool (8 fish/m3) and fed at 5 % of their body ...

Heart structure in the Amazonian teleost Arapaima gigas (Osteoglossiformes, Arapaimidae) [PDF]

Journal of Anatomy, 2018
AbstractThe fish heart ventricle has varied morphology and may have a specific morpho‐functional design in species adapted to extreme environmental conditions. In general, the Amazonian ichthyofauna undergoes constant variations in water temperature, pH and oxygen saturation, which makes these species useful for investigations of cardiac morphology ...

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Tensile Properties of 3D‐Printed Porous Bouligand Structured Polymer Plates

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
The tensile performance of porous Bouligand‐structured polymers is governed by pitch angle and fiber spacing. Experimental and FEA results reveal optimal strength and stiffness at 30∘$^\circ$, with mechanical efficiency scaling with density. These tunable bioinspired architectures bridge cellular solids and composites, offering lightweight, damage ...

Unprotected Waters: When Protection Fails In Freshwater

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT Invasive species are a major driver of biodiversity loss in protected areas (PAs), yet their impacts in aquatic environments are less well documented. This study investigated the occurrence and distribution of nonnative freshwater fish in federal PAs in Brazil.
