TroutEarlyNutrition - Metabolic programming in juvenile trout

Plant proteins for aquaculture feeds are of increasing importance. However, secondary plant compounds (antinutritive substances) can have a negative impact on digestibility and gut health of various fish species. The nutrition of juvenile trout is usually based on fishmeal and only on limited quantities of plant meals - in contrast to adult trout which is nowadays fed with high inclusion levels of plant proteins. Recent findings on epigenetic mechanisms in human nutrition will be transferred to fish in order to evaluate if first feeding with plant protein meals has a positive effect on the subsequent digestibility and animal health. It is already known that Rainbow trout fry can adjust digestive processes (e.g. enzyme activities) to a specific feeding regime and thus this study is supposed to take advantage of the process of adaptation. First feeding trout fry should adapt towards plant proteins, so that fishmeal inclusion levels can be successfully decreased and negative effects of secondary plant compounds on fish health prevented. Rainbow trout and Brown trout will be compared in order to evaluate the influence of potential adaptive processes that already occurred due to intensive breeding programmes within the last decades.

Die GMA hat sich zum Ziel gesetzt, den Entwicklungsprozess der Aquakultur und im speziellen der Marinen Aquakultur im Bereich der angewandten Forschung zu begleiten und zu unterstützen. Am Standort Büsum ist dazu 2009 ein Forschungszentrum entstanden, das nach den neuesten wissenschaftlichen und technischen Vorgaben eingerichtet ist. Gemeinschaft Aquaculture Research Center
