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

The consensus among several presenters at the aquaculture portion of the Alltech ONE18 conference was clear: Much more seafood is needed to feed humans, whose numbers will reach 8 billion in less than six years. 

Leader in fermentation, bio-refining technology a “great strategic fit” for single-cell protein aquafeed ingredient maker transitioning from R&D labs to commercial production. 

This study assessed the efficacy and nutritional properties of the marine alga Nannochloropsis salina as a feed ingredient using tilapia (Oreochromis niloticus) as a model species. Results showed adequate growth, survival, FCR and enhanced EPA levels. 

The World Aquaculture Society’s latest Lifetime Achievement Award recipient reflects on 50 years in the business of producing high-quality, nutritious feeds for the poultry, livestock and aquaculture industries. 

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. 

Biotechnology firm NovoNutrients aims to produce a line of nutraceutical aquafeed additives as well as a bulk feed ingredient that can supplement fishmeal. Its process includes feeding carbon dioxide from industrial gas to a “microbial consortium” starring hydrogen-oxidizing bacteria. 

A greenhouse in Belgium believes its innovative shrimp feed product, made from freeze-dried microalgae, packs the necessary nutrients for the crustacean’s most vulnerable life stage: the first three days of its life. 

Biannual conference/competition showcased 40 new seafood businesses, or related services, from around the world. Winners were chosen on the strength of the opportunity, meaningful impact and compelling leadership and presentation. 

Aquaculture could be a sustainable alternative to fishing for tuna but achieving commercial-scale production has proven challenging. 

The U.S. Soybean Export Council’s farm demonstrations, farmer education efforts and formulated feeds are boosting tilapia production in rural areas of Myanmar, where indigenous carp are more commonly raised. 

Aquaculture systems should be operated with attention to reducing the environmental waste load, which requires the use of high-quality feeds, prevention of overfeeding and maintenance of good water quality. 

KnipBio, a Massachusetts-based biotechnology startup founded in 2013, is refining the manufacturing process for a promising aquaculture feed ingredient that may one day form the foundation of the food that farmed fish eat. 

The physical integrity and nutrient leaching of shrimp aquafeeds are important aspects in their quality control. The water stability of shrimp aquafeeds is often evaluated in various subjective manners. This analytical procedure provides a baseline for the aquafeed manufacturer to assess product quality. 

Research shows farmed fish fed diets heavy on vegetable oils have higher amounts of omega-6s and lower amounts of omega-3s, compared to fish fed diets heavy on fish oil. We take a deep dive into the relationship between the two fatty acids.
