Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting.

Jellyfish (Chrysaora lactea, Cnidaria, Semaeostomeae) aggregations in southern Brazil and consequences of stings in humans

open access: yesLatin American Journal of Aquatic Research, 2014
The frequency of jellyfish blooms is generating a world-wide discussion about medusae population explosions, mainly those associated with stings. We report over 20,000 envenomations caused by Chrysaora lactea (Scyphozoa) in the State of Paraná (southern ...

Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.
