With byproducts, getting more from – and for – fish
Use of fish trimmings and byproducts in fishmeal and fish oil is a win for aquaculture. But challenges loom, including logistics and economics.
Third F3 Challenge centers on carnivores
The third marine-ingredient-free feed contest launches today with an eye on carnivorous species, which face scrutiny for their dependence on fishmeal and fish oil.
Mullet-based diets show promise as aquafeed ingredient
Findings of recent feeding trials with Siberian sturgeon and redfish demonstrate that mullet-based feeds can be substituted for traditional fishmeal resources.
After testing new feed ingredients, Thai Union finds reluctant uptake
The company has engaged in feed trials with both algae and microbial meals, before its sustainability director said farmers, “by and large, don’t want it.”
Towards sustainable aquafeeds: Evaluating fishmeal substitution
This study evaluated replacing fishmeal with a protein-rich and EPA-rich co-product of the marine microalga Nannochloropsis oculate in diets of Nile tilapia.
Identifying soil bacteria for protein supplements in aquafeeds
A commercial corn ethanol production byproduct (syrup) was used as a bacterial growth medium with the long-term aim to repurpose the resulting microbial biomass as a protein supplement in aquaculture feeds.
Pond-cultivated algae: Slimy superhero for aquafeeds?
Qualitas Health, which grows algae in ponds in New Mexico and Texas for human supplements, is entering the alternative aquafeed ingredient market.
IFFO, GAA urge Asian trawl fisheries to improve stocks, product quality
Fisheries improvements projects (FIPs) are an important mechanism for bettering South East Asian fisheries that supply into the aquafeed industry, a new report finds.
Long-term dietary replacement of fishmeal, fish oil in rainbow trout
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.
From bench to belly: Driving supply-side solutions for the future of fish feed
How can the interesting and valuable research on alternate feed ingredients get from the laboratory bench to consumers’ bellies through market mechanisms?
Feed formulations affect shrimp flavor, texture
Fish-free diets are suitable for shrimp production and can generate high-quality product. Consumer preferences for the flavor of shrimp and texture attributes need exploration.
Production of fatty acid, protein by Nannochloropsis in flat-plate photobioreactors
This study examined changes in the biochemical composition of the microalga Nannochloropsis sp. cultivated as a potential feedstock for aquafeeds, and presents results on its productivity, protein content and lipid composition.
Shrimp feed sustainability conundrum: Fishmeal substitution
A shift towards crop-based ingredients in shrimp feeds reduces dependency on marine resources but places resource demands onto the land and could impact the nutritional value of shrimp.
Functional ingredients driving shrimp feed innovation
Functional ingredients and additives promote growth, improve health of farmed shrimp, and bolster immune response and other physiological needs.
Aquafeed moonshots at the F3 ‘talent show’
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.
Single-cell protein aquafeed ingredient first to gain GRAS designation
Massachusetts-based biotechnology firm KnipBio is the first single-cell protein manufacturer serving the aquafeed industry to earn Generally Regarded as Safe designation from the U.S. Food and Drug Administration.
