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.
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.
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.
Analyzing aquaculture through Alltech’s Global Feed Survey
Alltech’s eighth annual Global Feed Survey, a compilation of estimated feed production data, reported that aquafeeds grew globally by 4 percent.
Testing soy-optimized feeds and automated feeding systems in shrimp pond production
Three years of testing clearly demonstrated that increasing daily feedings through the use of automated feeding systems – a transformational technology – can significantly increase the production and value of L. vannamei produced in semi-intensive pond culture.
Production of omega-3 enriched tilapia through dietary algae meal or fish oil
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.
Evaluating soybean-based diets for cage-raised red drum
A 15-week feeding trial evaluated the replacement of fishmeal with soybean products in the diet of advanced juvenile red drum.
A push for rapeseed as a viable aquafeed ingredient
One Germany-based company says rapeseed protein concentrate, or RPC, can help aquafeed manufacturers meet growing demand.
