Interannual variability of the reproductive strategy of the Peruvian anchovy off northern-central Peru

open access: yesCiencias Marinas, 2011
In this paper we analyze the standardized monthly anomalies of time series of the gonadosomatic index (GSI, 1986–2008), spawning fraction (SF, estimated by histological analysis of gonads, 1992–2008), and condition factor (1986–2008) of the Peruvian ...

Optimum sample length for estimating anchovy size distribution and the proportion of juveniles per fishing set for the Peruvian purse-seine fleet

open access: yesRevista Peruana de Biología, 2017
The length distribution of catches represents a fundamental source of information for estimating growth and spatio-temporal dynamics of cohorts. The length distribution of caught is estimated based on samples of catched individuals. This work studies the

Otolith elemental composition reveals separate spawning areas of anchoveta, Engraulis ringens, off central Chile and northern Patagonia

open access: yesScientia Marina, 2019
The anchoveta (Engraulis ringens) is widely distributed throughout the Humboldt Current (4°30′-44°S). In recent years, its eggs and larvae have also been found inside fjords and channels of northern Patagonia, close to the southern limit of the central ...

Extraction of collagen from wastes processing Engraulis ringens “anchovy”

open access: yesCiencia e Investigación, 2015
The aim of this study was to extract collagen from the waste produced in the processing of anchovies (canned and surimi). To this end, non-collagenous proteins was solubilized with a solution of 0,1N sodium hydroxide and neutralized with successive washes with water (pH close to neutral).

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

open access: yesConservation 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

Inter-population differences in temperature effects on Engraulis ringens yolk-sac larvae [PDF]

open access: yesMarine Ecology Progress Series, 2006
ABSTRACT: Early life stages of Engraulis ringens were reared from hatch until yolk exhaustion. Weevaluated the effect of temperature on characteristics such as larval length and yolk volume at hatch,larval length at yolk absorption, duration of yolk-sac stage, yolk consumption rate and larval growthrate. Further, we determined the potential differences

The Fish Behind Fish Feed: Rethinking Transparency Using DNA Tools

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 771-780, May 2026.
ABSTRACT Aquaculture is now the fastest growing food sector and may be a promising solution to increasing seafood demands. Yet, carnivorous aquaculture species such as salmon and seabass continue to rely on fishmeal and fish oil (FMFO), which are derived largely from pelagic fish that are sometimes key to the food security of some coastal nations. This

Elaboration of a powdered anchovy protein hydrolyzate (Engraulis ringens)

open access: yes, 2021
El objetivo del trabajo fue elaborar un hidrolizado de proteína en polvo utilizando anchoveta sin cabeza y eviscerado (HG) y determinar sus características sensoriales, físico-químicos y microbiológicos. En el proceso de hidrólisis se evaluaron siete proteasas comerciales. La actividad hidrolítica de las proteasas fue evaluada utilizando los valores de

Interactive Effects of Temperature and Soybean Meal‐Based Diets on the Physiological Status of Juvenile Totoaba macdonaldi: Growth and Blood Parameters

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Growth and haematological parameters are used in aquaculture as indicators of the health of cultivated fish in response to changes in diet and the physicochemical conditions of the water. In this study, the physiological status of Totoaba macdonaldi was evaluated based on growth, haematological parameters and blood chemistry in response to two
