IMPROVING UTILIZATION OF PLANT BASED DIETS IN RAINBOW TROUT AND EUROPEAN SEABASS: LESSONS FROM INFERENCE OF GENETIC PARAMETERS AND SELECTION EXPERIMENTS

摘要

The diet composition used in fish farming has strongly evolved during the last 30 years. Terrestrial plant-based products gradually replace fish meal and fish oil, as fish stocks used for their production reach their exploitation limit. However, the exclusive use of vegetable oils and meals still lead to growth and health degradation in salmonids and marine fish. In same time, the genetic improvement in fish farming allowed strong improvements, since 1980, on growth, health and product quality.
