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. 

A business accelerator helps small businesses grow and ready themselves to capitalize on institutional investment opportunities. Sounds exactly what the aquaculture industry needs. Carsten Krome tells the Advocate about the various business models his new firm is investigating. 

One of the world’s leading fish nutrition experts talks about how aquaculture can learn to survive, and even thrive without depending on fishmeal and fish oil. It’ll take a lot of innovation, but Giovanni Turchini is confident that the industry is on the right path. 

Carotenoids are important pigments that contribute characteristic quality criteria for the marketing of aquaculture products. Aquatic animals cannot biosynthesize carotenoids de novo, hence their inclusion in aquafeeds is important because they are associated with various metabolic functions. 

The U.S. Soybean Export Council is a huge supporter of aquaculture growth globally, as so many aquafeed formulators rely on U.S. soy to create nutritious diets. The Southeast Asia senior technical advisor for USSEC’s aquaculture program talks about this symbiotic partnership. 

In an opinion piece for the Advocate, the director of ocean sustainability science at the New England Aquarium talks about the F3 Challenge and what the first X Prize for aquaculture could do for the industry: drive innovation.  

Since fish consume more feed in the final stages of growout, the development of ecologically efficient and nutritionally adequate diets for adult fish should be a priority. Digestible protein-digestible energy ratios are important for optimizing feeding efficiency in feed formulation and aquaculture production. 

Turbot are typically fed diets containing 45 to 65 percent fishmeal. In a study that gave turbot feed with 40 percent soy protein concentrate, the fish had decent growth and excellent survival. 

To help produce high-quality aquaculture feeds, the U.S. Soybean Export Council spearheaded the Asian Aquaculture Feed Formulation Database project, designed as a reference tool for individuals involved in feed formulation, ingredient purchasing, quality control and research. 

Poor-quality ingredients can’t become good-quality ingredients. Quality protein is essential for the healthy growth of any omnivorous or carnivorous aquaculture species. Insect meals seem to fill this need, and their mass-scale production appears to be sustainable. 

In life cycle analysis of aquaculture, there is a danger of the entire array of embodied resources and impacts being assigned to the production facility. Producers have no control over the inefficiencies or impacts associated with feed production, but can help lessen resource use through good management practices. 

A growth trial in Canada evaluated the use of algae biomass to increase the concentration of long-chain polyunsaturated fatty acids in the tissues of rainbow trout.
