The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Refining a molecular tool kit to capture tropicalization in Mediterranean marine protected areas

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
We assess complementarity and trade‐offs between visual census and eDNA metabarcoding for monitoring fish community changes in MPAs. Abstract Tropicalization, the process by which tropical species expand their ranges poleward due to global ocean warming, is a prominent threat to Mediterranean marine ecosystems, challenging their effective management ...

The Fish Behind Fish Feed: Rethinking Transparency Using DNA Tools

Fish and Fisheries, Volume 27, Issue 3, Page 771-780, May 2026.
ABSTRACT Aquaculture is now the fastest growing food sector and may be a promising solution to increasing seafood demands. Yet, carnivorous aquaculture species such as salmon and seabass continue to rely on fishmeal and fish oil (FMFO), which are derived largely from pelagic fish that are sometimes key to the food security of some coastal nations.
