Work Package 6

WP 6: Tailoring fish performance with sustainable feeds: nutritional programming



This workpackage will measure long-term effects of changes in diet formulations on fish performance, such as threshold effects, nutritional intervention in early life history stages, and carry-over from maternal diets to larvae.


The objectives of this Workpackage are to improve the use of alternative diets by adult fish through the nutritional programming concept i.e. by producing a specific nutritional stimulus (stress) at critical developmental stages to modify permanently the adult fish.

Planned Activities:

We focus our studies on assessing nutritional programming at two different developmental stages: at the stage of strict endogenous feeding using yolk reserves and at the stage of first feeding.

Action at the endogenous feeding stage. We will modify the nutritional value of the yolk reserves through maternal nutrition or by direct action on egg composition in trout, salmon, carp, sea bass and seabream; this stimulus could program metabolic pathways and contribute to increased growth potential and homogenous performance.

Action at the first feeding stage. . The first feeding stage is a highly critical developmental window and allows us to validate the metabolic programming concept with specific diets or nutrients; these studies will be developed with trout, sea bass and seabream.

Final challenge to test of the nutritional programming in juvenile fish. In order to test the existence of the nutritional programming in fish, we need to challenge fish at a later stage with alternative diets or specific nutrients.

Expected results:

  • Proof of the nutritional programming concept in fish by analysis of the phenotype (metabolic) consequences of the precocious nutritional treatment
  • Improve the metabolic potential of adult fish and performance with alternative diet
