Connecting sea to market: Using network analysis to understand social–ecological dynamics in seafood value chains in Pisco, Southern Peru

People and Nature, Volume 7, Issue 10, Page 2465-2485, October 2025.
Abstract Small‐scale fisheries represent complex human‐nature interactions, targeting different species in different locations throughout the year. On land, fishers are at the core of diverse seafood value chains that serve local and distant markets.

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

The Interaction Between Stock Dynamics, Fishing and Climate Caused the Collapse of the Jack Mackerel Stock at Humboldt Current Ecosystem

Frontiers in Marine Science, 2020
The collapse of marine fisheries had caused a cascade of ecological, social and economic consequences. Recognizing the complex nature of the fisheries collapses is essential for understanding the impact of human activities on natural systems.

Impacts of climate‐related stressors on social group cohesion and individual sociability in fish

Biological Reviews, Volume 99, Issue 6, Page 2035-2059, December 2024.
ABSTRACT Group‐living in animals comes with a number of benefits associated with predator avoidance, foraging, and reproduction. A large proportion of fish species display grouping behaviour. Fish may also be particularly vulnerable to climate‐related stressors including thermal variation, hypoxia, and acidification.

Parasites of Kunene horse mackerel Trachurus trecae (Smith-Vaniz, 1986) with a comparison of parasites of Cape horse mackerel T. capensis (Castelnau, 1861) in the northern Benguela [PDF]

, 2013
Two species of horse mackerel (Trachurus trecae and Trachurus capensis) reside in the northern Benguela ecosystem. Both are important economic commodities for the Angolan and Namibian fisheries and therefore need to be managed appropriately. Although the

Hyperostosis in Fishes: An Update With New Species Records

Journal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Can small pelagic fish landings be used as predictors of high-frequency oceanographic fluctuations in the 1–2 El Niño region? [PDF]

Advances in Geosciences, 2016
A group of small pelagic fish captured between 1981 and 2012 within El Niño area 1–2 by the Ecuadorian fleet was correlated with the oceanographic Multivariate ENSO Index (MEI), and the Oceanographic El Niño Index (ONI) referred to El Niño region 3–4.
