Gastrointestinal functions and food intake regulation in Salmonids: Impact of dietary vegetable lipids

Objective

OBJECTIVES AND EXPECTED ACHIEVEMENTS
The gastrointestinal tract has a number of vital functions. In fish as in other vertebrates, the gastrointestinal tract is the site of food digestion and nutrient uptake, imparts postprandial information for the regulation of food intake, is a regulatory site for ion and water balance, and acts as a barrier against infections. Changes in diet composition may affect any of these functions, and thus the nutritional and osmoregulatory balance, hunger and satiation level, disease resistance and health.

The maintained integrity of the gastrointestinal tract, irrespective of diet composition, is therefore of major production concern during finfish aquaculture, as well as an important issue of animal welfare.

PROJECT OBJECTIVES:
The overall goal of the project is to provide a strong factual basis for the quantitative and qualitative incorporation of vegetable lipids into feed for salmonids, a group of commercially important European aquaculture species.
