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

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

Ontogenetic and spatiotemporal variability in anchoveta Engraulis ringens diet off Peru
Journal of Fish Biology, 2014 In this study, historical data available since 1954 were used to get new insight to ontogenetic and spatiotemporal variability in Peruvian anchovy or anchoveta Engraulis ringens diet. Whatever the period, E. ringens foraged mainly on macrozooplankton and the importance of euphausiids in E. ringens diet appears directly related to euphausiids abundance.
