Long‐Term Dynamics of the Northern Humboldt Current System Pelagic Fish Community: A Look Into Community Shifts

Marine Ecology, Volume 46, Issue 5, September/October 2025.
ABSTRACT The northern Humboldt Current System (nHCS) has high environmental variability that impacts key demographic and community‐scale processes. Understanding the role and ecological implications of these interannual or long‐term events is crucial in describing the dynamics of the nHCS community. Using catch data from pelagic assessment surveys from

Automatic Discrimination between Scomber japonicus and Scomber australasicus by Geometric and Texture Features

Fishes, 2018
This paper proposes a method for automatic discrimination of two mackerel species: Scomber japonicus (chub mackerel) and Scomber australasicus (blue mackerel). Because S. japonicus has a much higher market price than S.

Current Affairs: Examining the Use of Environmental DNA for Relative Abundance Monitoring in a Dynamic Tidal Habitat

Environmental DNA, Volume 7, Issue 3, May–June 2025.
This study evaluates the feasibility of using environmental DNA (eDNA) metabarcoding to estimate the relative abundance of marine species in Sussex Bay, UK. Although eDNA detected more species than Baited Remote Underwater Video (BRUV), a significant correlation between eDNA index and BRUV MaxN was found for only one out of fourteen species analyzed ...
