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

Fatty acids in eggs of anchoveta Engraulis ringens during two contrasting winter spawning seasons [PDF]
We assessed the fatty acid (FA) composition of anchoveta eggs collected from the plank- ton along with female anchoveta reproductive traits and environmental conditions during peak win- ter spawning in 2005 and 2007. Environmental conditions differed markedly between years at 3 con- tinental shelf stations off Talcahuano, Chile, with a warmer, fresher ...

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

The intestine as a diagnostic character in identifying certain clupeoids (Engraulididae, Clupeidae, Dussumieriidae) and as a morphometric character for comparing anchoveta (Centengraulis mysticetus) populations [PDF]
ENGLISH: The several species of clupeoid fishes used as baitfish in the Eastern Pacific tuna fishery are, in some cases, sufficiently similar to make identification difficult.

Establishing company level fishing revenue and profit losses from fisheries: A bottom-up approach. [PDF]
A third of global fish stocks are overexploited and many are economically underperforming, resulting in potential unrealized net economic benefits of USD 51 to 83 billion annually.

Nutrient and light availability control food webs and fish larvae in the Peruvian upwelling system
Abstract Upwelling ecosystems sustain some of the world's most productive fisheries by supplying deep‐water nutrients to the sunlit ocean surface. Yet, how spatiotemporal variability in nutrient‐upwelling and light availability regulates trophic transfer to fish remains poorly understood. We investigated these dynamics in a 36‐d mesocosm experiment off

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

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

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.

ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...
