Genetic variability in jack mackerel Trachurus murphyi Nichols: New SSRs loci and application [PDF]

Gayana (Concepción), 2012
Nueve nuevos loci microsatelites fueron desarrollados para Trachurus murphyi. Estos loci fueron caracterizados en muestras de tres localidades a lo largo del oceano Pacifico suroriental. Uno de los loci fue monomorfico, mientras que para el resto de los loci el numero de alelos por locus oscilo entre 6 a 16 y la heterocigosidad esperada entre 0.653 a 0.

Effect of a previous high hydrostatic pressure treatment on lipid damage in chilled Chilean jack mackerel (Trachurus murphyi)

Grasas y Aceites, 2013
Lipid damage evolution was analyzed in chilled Chilean jack mackerel (Trachurus murphyi) previously treated with high hydrostatic pressure (HHP) technology. Different pressure levels and pressure holding times were tested. In addition, fish corresponding

Safeguarding Seafood Security, Marine Biodiversity and Threatened Species: Can We Have Our Fish and Eat It too?

Frontiers in Marine Science, 2022
The ocean contains an abundance of biodiversity that is vital to global food security. However, marine biodiversity is declining. Marine protected areas and marine reserves have been used to protect biodiversity, conserve threatened species and rebuild ...

The catch of the day: The shortcomings of promoting sustainable seafood consumption in Peru

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
This study investigates the meaning and application of “catch of the day” in Peru by analyzing 233 news articles and genetically testing 43 fish samples from restaurants. Results show that media frequently use the term as a vague marketing phrase, while genetic testing reveals a 60% mislabeling rate. These findings suggest that “catch of the day” lacks

Fisheries Trade and Blue Nutrient Flows in Pacific Island Countries

Fish and Fisheries, Volume 27, Issue 3, Page 466-477, May 2026.
ABSTRACT Pacific Island Countries (PICs) are located in highly productive fishing regions that supply nutrient‐rich fish to global markets. Marine fisheries are a critical source of protein and essential micronutrients for billions of people worldwide, supporting both local diets and global food security.

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.

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.

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

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.
