Bridging the gap from ocean models to population dynamics of large marine predators: A model of mid-trophic functional groups [PDF]

, 2009
The modeling of mid-trophic organisms of the pelagic ecosystem is a critical step in linking the coupled physical–biogeochemical models to population dynamics of large pelagic predators. Here, we provide an example of a modeling approach with definitions

Temperature effects on the anchoveta Engraulis ringens egg development: do latitudinal differences occur?

Environmental Biology of Fishes, 2007
We assessed differences in the development rates among anchoveta, E. ringens populations from the extremes of its range under different temperatures. Time to hatch decreased with increasing temperature but there was no difference in the temperature–development time relationship between eggs from different localities.

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.

Nutritional Characteristics of a Peruvian Anchovy (Engraulis ringens) Protein Concentrate

Journal of Aquatic Food Product Technology, 2020
The aim of the present study is to present a new anchovy protein concentrate and compare it to other similar fishery products. A 76.4% protein concentrate was prepared from fresh Peruvian anchoveta (Engraulis ringens) (APC) by means of acid treatment with 1% citric acid, solubilization with 1% sodium chloride, and isoelectric precipitation processes ...

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

Acoustic observation of living organisms reveals the upper limit of the oxygen minimum zone. [PDF]

PLoS ONE, 2010
BACKGROUND: Oxygen minimum zones (OMZs) are expanding in the World Ocean as a result of climate change and direct anthropogenic influence. OMZ expansion greatly affects biogeochemical processes and marine life, especially by constraining the vertical ...
