AQUACULTURE
The biotechnological potential of crickets as a sustainable protein source for fishmeal replacement in aquafeed
Aquaculture demands cost-effective protein sources as fishmeal (FM) prices rise. Cricket meal (CM) is a sustainable alternative with high protein content and digestibility, supporting growth, immunity, and gut health in fish and shrimp. While chitin content and scalability pose challenges, biotechnological solutions can improve the protein quality for its safe use in aquafeed.

Algae-based ingredients prove effective in salmon feed trials
This research evaluated the inclusion of AlgaPrime™ DHA LS microalgae in Atlantic salmon feeds, focusing on lipid extraction and digestibility. The inclusion of AlgaPrime™ DHA LS was tested before extrusion and in the vacuum coating step, showing good physical stability and nutrient digestibility, including saturated fatty acids. The addition of microalgae in the vacuum coating step allowed for high oil absorption without significant loss. The results showed no need for additional cell wall rupture of the microalgae, and replacing part of the oils with AlgaPrime™ DHA LS did not negatively affect digestibility in salmon, demonstrating a favorable lipid profile.

MARINE BIOTECHNOLOGY
Extraction and purification of biopolymers from marine origin sources envisaging their use for biotechnological applications
Biopolymers from marine sources are sustainable alternatives for cosmetics, medical, and food uses. Various extraction methods have been explored for obtaining polysaccharides, proteins, and glycosaminoglycans from marine resources, such as agar from seaweeds, chitin from crustaceans, and collagen from fish. This review describes the established extraction and purification techniques. It also includes a practical guide with protocols for more efficient and environmentally friendly extraction methods.
