Protein and growth efficiency in salmonid selection

Objective

The overall goal is to establish a sufficient knowledge base to facilitate new selection programmes aimed at improving protein growth.

Three major objectives are identified:
1. To provide reliable heritabiity estimates for protein growth, protein efficiency and meat quality.
2. To develop predictive tools to recognise the high quality genotypes of these important traits with the help of genetic correlations and growth curve models for protein growth and lipid deposition.
3. To understand the biological correlatives causing variation in these traits, genetic correlations and growth curves. Six work packages form a three step work plan.

The first consists of rearing rainbow trout according to a carefully planned family-based breeding scheme to provide the necessary genetic setup. The number and measurements of fish to be sampled to obtain reliable genetic information is large but has been optimised for this project by a simulation study to make it more manageable.
