The role of arginine in the health and performance of juvenile Gibel carp

In an eight-week study with juvenile Gibel carp, diets enriched with different levels of arginine (0.2%, 0.4%, 0.6%, and 0.8%) showed significant effects. Moderate supplementation (about 0.4% to 0.6%) boosted growth, while higher doses activated essential genes associated with antioxidant defense (Nrf2) and oxygen regulation (HIF-1). Interestingly, inflammation markers remained largely unchanged. The conclusion? Arginine not only promotes growth but also supports immunity, strengthens antioxidant defenses, and improves oxygen transport, making it a vital nutrient for healthier, more resilient fish.

Shrimp sector in Asia: leading the global transformation of aquaculture

Shrimp aquaculture is undergoing a process of modernization, adopting technology and sustainable practices to increase production. Responsible for almost 80% of global production, the Asia-Pacific region is both the backbone of the industry and the driving force behind its transformation. The sector in the region is incorporating precision nutrition, innovation, and sustainable practices to improve efficiency and resilience while minimizing environmental impact. By combining scale with responsibility, Asia-Pacific is leading the new era of shrimp farming, demonstrating that growth and sustainability can go hand in hand.

In vitro antioxidant and antidiabetic effects of Chlorella lipids
Microalgae are emerging as powerful mini-factories for the production of valuable bioactive compounds. In this study, lipid extracts from three Chlorella species were analyzed for their chemical composition and health-promoting properties. GC–MS analysis revealed several bioactives—ranging from n-hexadecanoic to octadecanoic acids—among the species, with C. sorokiniana standing out. This species not only exhibited the strongest antioxidant activity but also most effectively inhibited the main enzymes associated with diabetes. These findings position the KU.B2 strain of C. sorokiniana as a promising biotechnological platform for drug development, transforming microscopic algae into a source of great potential.

Effects of Tetradesmus obliquus Mi175.B1.a on gut and mental health in healthy adults

Daily supplementation with Tetradesmus obliquus extract (TOME) for four weeks helped healthy adults with mild to moderate gastrointestinal discomfort. Participants showed significant improvements in intestinal symptoms, including constipation and indigestion, as well as positive changes in the composition of their gut microbiota. In addition to digestive benefits, TOME also reduced stress levels and negative mood while decreasing plasma biomarkers associated with stress. These findings highlight the potential of TOME as a natural gut-focused intervention that supports both digestive health and mental well-being.

MARINE BIOTECHNOLOGY

Turning seaweed into opportunity in the Caribbean

Young Dominicans from SOS Carbon have turned the seaweed crisis in the Caribbean into an innovative solution by harvesting seaweed from the sea before it reaches the beaches. This action protects marine ecosystems, reduces coastal erosion, and creates jobs for local fishermen. SOS Bayotec, a blue biotechnology branch, converts sargassum into agricultural biostimulants, increasing plant productivity and quality. Up to 70 tons are removed per day, preventing severe economic and environmental impacts. The project adds value to the local supply chain, avoiding the export of raw materials.

Extraction of omega-3 from marine lipids using supercritical fluids

This application describes a method for extracting fatty acids from lipid-rich marine organisms. The process involves: (a) treating the starting material with a supercritical fluid under specific temperature and pressure conditions, and (b) collecting the resulting fatty acid-rich extract. Prior to extraction, the material may be subjected to pretreatments such as drying, grinding, and/or immersion in an organic solvent.
