Authors investigated the effects of replacing dietary fish oil with palm oil in juvenile Nile tilapia, and demonstrated that growth and feed utilization were not compromised when palm oil was used either partially or totally. 

Fisheries improvements projects (FIPs) are an important mechanism for bettering South East Asian fisheries that supply into the aquafeed industry, a new report finds. 

This study evaluated the effects of replacing fishmeal and fish oil with a plant-based diet in juvenile and on-growing rainbow trout from first-feeding. 

How can the interesting and valuable research on alternate feed ingredients get from the laboratory bench to consumers’ bellies through market mechanisms? 

At the F3 (fish-free feed) Companies Got Talent event in Burlingame, Calif., last week, alternative (non-marine) aquafeed ingredient companies spoke of decoupling aquaculture from fishmeal and fish oil in their quest for greater sustainability. 

This study evaluated the effect of diets supplemented with fish oil and algae meal for LC-PUFA enrichment on juvenile Nile tilapia. The experimental diets have promise as a feasible option for enriching omega-3 content in tilapia fillets. 

Libby Woodhatch says responsible sourcing and safe raw material production is “vital” if fishmeal and fish oil are to remain credible aquafeed ingredients. 

At the Barcelona Seafood Summit, an expert panel discussed a sustainable future for aquafeeds. What stands between us and that future? 

The Future of Fish Feed (F3) initiative aims to jumpstart innovation in terms of viable fish-free substitutes to fish oil through the global F3 Fish Oil Challenge. 

The benefits of omega-3 fatty acids to human health are well known. Fish need them too. To supplement current supplies from wild-caught fish, one innovative venture is turning to the corn fields of Nebraska – yes, Nebraska – for answers.  

This study shows that soybean oil can totally replace fish oil in California yellowtail aquafeeds without affecting production performance and reducing the omega-3 fatty acid profile of fish tissues, as long as acceptable levels of ARA and DHA are provided. 

To position aquaculture for future growth, it needs tools to evaluate a growing spectrum of alternative ingredients and formulated diets designed to optimize fish health and efficient production. 

Formed in 2015, following Cargill’s acquisition of salmon feed specialist EWOS to complement its own warm-water aquaculture feed business, Cargill Aqua Nutrition produces feed for salmon, tilapia and shrimp in 20 countries around the world. 

The latest Fish In:Fish Out (FIFO) ratios calculated by IFFO – The Marine Ingredients Organisation shows that every kilogram of wild fish utilized in aquafeeds results in a total of 4.55 kilos of farmed fish produced. 

A key to expanding aquaculture is finding alternative sources of proteins and oils. Supplementing or replacing fish oil in aquaculture feeds with alternative lipid sources – oils seeds, microalgae, insects and others – appears possible as long as essential fatty acid (EFA) requirements are satisfied.
