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. 

Los métodos eficaces de manejo de los alimentos acuícolas son fundamentales para la producción eficiente de camarón cultivado y para minimizar el impacto ambiental. En la segunda parte de su serie, el Editor Emeritus Darryl Jory analiza la gestión de la alimentación de camarón en términos de aplicación, distribución, frecuencia, cálculos y prácticas de ajuste. 

Giovanni Turchini, associate professor at Deakin University (Australia) spoke at the GOAL 2016 conference in Guangzhou, China, and gave a comprehensive historical look at global fishmeal usage. 

Shrimp production systems and their feed management must be considered together. It requires an understanding of biological aspects of the targeted species and age, of production system used, of chemical and biological processes that control water and bottom quality and continuous system monitoring and feedback to provide appropriate and timely inputs and adjustments.
