This study evaluated a commercially available prebiotics and probiotics under conditions simulating commercial production in hybrid catfish. Results showed that the various dietary treatments did not have any significant effects on processing characteristics or composition.
A two-year grant of $276,000 seeks to improve the nutrition of live feed for, and therefore the production of, larval California yellowtail and halibut, with the hopes that the technology will be applicable to other species.
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.
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.
Results of this study show that automated feeding systems are significantly more efficient than hand feeding in shrimp production ponds and that increases in feed input, application of adaptive technology and training of people to maintain the feeding system must all be considered.
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.
Results of a study show that alternative, sustainable, plant-based protein sources such as improved soybean meal may potentially replace fishmeal in Pacific white shrimp diets.
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.
Studies showed that the demand feeding system for farmed shrimp – based on multi-rations and combined with sound detection – can be used to distribute the correct dosage of aquafeed with high nutritional density.
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.
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.
In this feeding study with Pacific white shrimp juveniles cultured at very high density in a closed system, results showed that continuous feeding with a high protein diet is less practical than feeding the shrimp with a low protein diet and under mixed feeding schedules.
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.
Study evaluated production performance and tissue composition of juvenile Florida pompano fed diets containing fish oil or 25:75 blends of fish oil and various other lipid sources.
