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.

Mechanical Strength of the Interfibrillar Matrix in Horse Mackerel(Trachurus murphyi) Tissue.
A transparent testing cell was constructed to assess flow of fish tissue during a compression-back extrusion mechanical assay. The net action of the plunger over the fiber-interfibrillar collagen matrix appears to involve flow of intact fibers due to yield of the matrix as well as compression resisted by fibers. The force at yield point F (N) coincided

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
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.

Hyperostosis in Fishes: An Update With New Species Records
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.

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.

Clarifying a trophic black box: stable isotope analysis reveals unexpected dietary variation in the Peruvian anchovy Engraulis ringens [PDF]
Background Small fishes play fundamental roles in pelagic ecosystems, channelling energy and nutrients from primary producers to higher trophic levels.

Hydrophobic natural deep eutectic solvents for marine lipid extraction
Abstract ‘Type V' natural deep eutectic solvents (TV NADES) are a novel class of solvent media with many potential ‘green chemistry’ applications. Here, we assess the potential of two TV NADES: menthol:carvacrol (M:C) and menthol:thymol (M:T), and a single terpenoid extraction media carvacrol (C), as media from total lipid extraction of three ...
