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

open access: yesConservation 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

Preliminary data on Trachurus picturatus (Bowdich 1825) phylogeography inferred from mitochondrial DNA sequence data

open access: yesFrontiers in Marine Science, 2015
The populations of marine pelagic fishes, in particular the migratory ones as the Trachurus picturatus (Bowdich 1825), may be erroneously considered an homogenous population unit because they show broad geographic distributions, large population sizes ...

Novel Assay for Endangered Hong Kong Grouper (Epinephelus akaara) to Assess eDNA Shedding, Decay, and Population Status

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)

Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 99-115, March 2026.
ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.

DETECTION OF MESOSCALE OCEANIC FEATURES USING RADARSAT-1, AVHRR AND SEAWIFS IMAGES AND THE POSSIBLE LINK WITH JACK MACKEREL (TRACHURUS MURPHYI) DISTRIBUTION IN CENTRAL CHILE

open access: yesGayana, 2004
In order to verify the ability of RADARSAT-1 images to detect mesoscale oceanic features and the possible link of these oceanographic patterns with jack mackerel (Trachurus murphyi) distribution in the waters off central Chile, a project was developed as
