The future of fishmeal and fish oil in aquaculture diets
Update: 9/4/2013
Production of fishmeal & fish oil
Seasonal surplus of less desirable fish and inedible by-products are collected.
They are efficiently converted into concentrated stable products which can be economically shipped to where they are required
Where are the raw materials of the future going to come from?
Fewer whole fish and more by-products
By 2020 50% of the fish raw material could be coming from by-products
The growth of aquaculture will mean more and more of the by-products will come from farmed species
New sources of raw material : krill & algae
The result of the growing replacement of fish oil in salmon diets:
Salmon farming has been a tremendous deliverer of omega-3
The nutrient requirements of the salmon can be met by low dietary levels of fish oil (5%)
The final level of EPA/DHA in the fillets will decrease
Salmon have been sold on their health giving properties and this will be increasingly challenged
Key takeaways
- Aquaculture relies on safe, healthy and nutritious feeds to produce quality seafood
- Fishmeal is a key natural ingredient for fish feeds to promote growth and welfare
- And the healthiest omega-3 is from fish oil
- Responsible sourcing of marine ingredients is a must – the IFFO RS program allows this
- Aquaculture will continue to grow by reducing inclusion levels of fishmeal & oil and using them as strategic ingredients
