B2E presents the eighteenth edition of Technological Sonar, our monthly selection of noteworthy national and international initiatives in the field of new patents and technologies in the blue bioeconomy sector.

Aquaculture

Improved feed additive for aquaculture

A feed additive suitable for use in commercial aquaculture, made from dried seaweed powder supplemented with 2.5% (w/w) andrographolide, increases the feed conversion ratio (the ratio between weight gain and the weight of feed used) and the growth rate, while reducing vulnerability to waterborne marine pathogens such as Piscirichettsia salmonis and white spot syndrome virus.

Are we getting closer to fish-free nutritional solutions?

Recent tests by the F3 Innovation Network have found that it is feasible and economically viable for aquaculture nutrition specialists to significantly reduce – or even eliminate – fishmeal and fish oil from the diets of carnivorous fish species such as Achingã, Seriola, and pompano.

Process to reduce fluoride content in the production of krill protein concentrate

The presence of fluoride in the exoskeleton of crustaceans, and especially in krill, represents a problem for its use as a food source, animal feed, feed additives and/or food additives. A process for removing this fluoride from krill has been developed, subjecting it to fragmentation and an enzymatic hydrolysis process before, or simultaneously with, the removal of exoskeleton particles, producing a product with reduced fluoride content. Inherent to the described process is the ability to process krill with a high content of polar lipids to produce superior quality products with low fluoride content, suitable for the food and animal feed industry, as well as for the pharmaceutical, nutraceutical and cosmetic industries.

Bacteriophage Composition for the Treatment of Clostridium perfringens Infections

The invention relates to the field of phage therapy. It is particularly related to the development of phages, phage-based compositions, and methods for treating or preventing bacterial infections, particularly C. perfringens, in animals, including humans, aquaculture, and livestock. The invention also relates to the use of the compositions as animal feed and as a form of biological decontamination in feed and food products for human and animal consumption.
