Evaluating the effect of protists in diets for Pacific white shrimp
Cumulative mortality results showed that shrimp fed protists (containing Aurantiochytrium sp. meal) had higher survival when challenged with WSSV.

Omega-3 fatty acids linked to reduced cancer risk, highlighting potential benefits of fish oil
A new study found that higher omega-3 and omega-6 levels in fish oil may lower the risk of up to 19 types of cancer.

Effect of HUFA-enriched artemia on the performance of Pacific white shrimp postlarvae
Feeding HUFA-enriched artemia to L. vannamei for 12 days significantly increases highly unsaturated fatty acid content in the shrimp postlarvae.

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.

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.

Integrated utilization of microalgae grown in aquaculture wastewater
A study shows that wastewater from recirculating aquaculture systems is suitable for microalgal cultivation and that sludge amendment to the wastewater increases production.

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.

It takes guts to advance sustainability in aquaculture
With byproducts representing between 25 to 50 percent of the weight of various fish species, we need to be looking at how the entire fish is being used: even the heads, guts and skin.

Are omega-3s in farmed jade perch as high as believed?
Farmed jade perch – similar to other cultured fish species – is only rich in omega-3 fatty acids if its diet consists of these nutrients in high amounts. How does it compare to the wild fish?

Phytoplankton in aquaculture ponds: Friend or foe?
A vigorous phytoplankton bloom will support a healthy benthic community and will contribute significantly to stabilising and maintaining adequate pond water and bottom quality.
