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 ...

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

Extraction of collagen from wastes processing Engraulis ringens “anchovy”
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
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]
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
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)
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

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
