A MODEL OF BYCATCH INVOLVING A PASSIVE USE STOCK

We develop a simple extension of the theory of multispecies fisheries management to analyze a problem where one fish or animal stock has no commercial market but instead is valued passively.

Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour

Journal of Fish Biology, EarlyView.
Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

A machine learning approach for protected species bycatch estimation

Frontiers in Marine Science
IntroductionMonitoring bycatch of protected species is a fisheries management priority. In practice, protected species bycatch is difficult to precisely or accurately estimate with commonly used ratio estimators or parametric, linear model-based methods.

Repositories of biocultural diversity: Toward best practices for empowering ethnobotany in digital herbaria

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1095-1103, July 2026.
Societal Impact Statement As herbaria digitize millions of plant specimens, ethnobotanical information associated with them is becoming increasingly accessible. These biocultural data include plant uses, names, and/or management practices of Indigenous Peoples and Local Communities (IPLCs).

Estimates of Spawning Stream Contributions to an Imperilled Bull Trout Metapopulation Utilizing Otolith Geochemistry and Redd Counts

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Migratory fish species have experienced substantial declines throughout aquatic habitats, but actions to manage and conserve migratory species require a better understanding of the relative contributions of local populations to the metapopulation.
