Device, system and method for detecting amyloodiniosis

Amyloodiniosis is detected using affinity reagents that cross-react with one or more antigens of *A. ocellatum* or *P. pillulare*. The analysis can be performed on board the ship, on the dock, in an aquaculture or aquarium environment, or in situ at the sample collection point or elsewhere. The results can be used to monitor the health status of captured or farmed fish species, as well as the safety of water to be introduced into an aquaculture facility.

Use of formic acid furan compound in the preparation of an animal feed additive

The use of a formic acid furan compound in the preparation of an animal feed additive to improve the production performance of domestic animals, poultry, and aquaculture animals in animal breeding tests is disclosed. The formic acid furan compound, or a feed-acceptable salt, presented in the present invention, has a performance-enhancing effect on domestic animals, poultry, and aquaculture animals in a breeding context.

Nutritional, Organoleptic and Sensory Quality of Commercial-Sized European Sea Bass (Dicentrarchus labrax) Fed with Delipidized Meal of Tenebrio molitor Larvae as the Main Protein Source

This study evaluated the impact of replacing 50% and 100% of fishmeal protein with delipidized (d-) Tenebrio molitor™ in diets for commercial-sized European sea bass. Despite some differences in muscle histomorphometric measurements and instrumental texture, consumers were unable to perceive differences between muscle samples from fish fed the control or dTM diets. All samples were characterized by their soft and pleasant texture, and the dTM samples were also associated with a “juicy texture”.

Enzymatic Approach for Extracting Bioactive Fractions from Red, Green, and Brown Algae

Red algae extracts exhibited prebiotic activity that can be attributed to their higher content of oligosaccharides and proteins/peptides. In general, the sequential use of enzymes with different activities proved to be an efficient approach to extract functional fractions to be used as functional ingredients to improve nutritional value (e.g., in proteins) and/or include antioxidant and prebiotic characteristics in the food product.
