AQUACULTURE
Systems and methods for enhancing macroalgae production
This disclosure relates to the enhancement of macroalgae production, particularly through the use of microorganisms or holobionts. It includes methods and compositions for beneficial macroalgae holobionts, such as bacterial combinations that promote growth. These compositions may be in powder or freeze-dried form and can contain bacteria such as Alteromonas and Alcanivorax. They can be applied in aquaculture systems, whether in tanks or ocean-based environments. The disclosure also covers macroalgae treated with these compositions, methods of use, and related kits.

Amphenicol adjuvant improves bioavailability and efficacy
Amphenicols are a class of antibiotics widely used in applications such as aquaculture. Administering an amphenicol alongside andrographolide enhances its bioavailability and efficacy, allowing for a reduced dosage of the amphenicol. This, in turn, decreases residual amphenicol levels in the harvested animal.

Device for reducing exterior parasites on fish
The invention relates to a device for reducing parasites on fish, comprising: i) an inclined filter element (with openings from 0.5 mm to 50 mm); ii) an inlet channel with a vertical drop (0 cm to 50 cm) for fluid communication; iii) parasite removal nozzles that eject fluid around a target volume (V), positioned at a downstream distance (0 cm to 50 cm); and iv) at least one of these measures (vertical drop or downstream distance) must be equal to or greater than 2 cm.

Innovasea unveils cutting-edge seabream biomass estimator
Innovasea has launched BiomassPro, the first commercial algorithm for estimating sea bream biomass, which supports six fish species. It autonomously analyzes fish stocks and provides accurate biomass estimates through a dashboard, eliminating the need for manual sampling. Rigorous testing with Aquafrais Cannes in France demonstrated up to 95% accuracy and significantly reduced labor requirements. An algorithm for European sea bass is expected later this year.

Bioactives from marine resources as natural health products: A review
The oceans are a rich source of unique natural products, mainly from invertebrates, with potential medical applications. With rising antibiotic resistance and cancer being leading causes of death, marine bioactives have shown great potential in developing antimicrobial and anticancer compounds. Many are currently in clinical trials, and some have been FDA-approved. This review explores their sources, mechanisms, and potential in medicine, emphasizing their role in advancing healthcare while supporting marine conservation.

Extracts of Chlamydomonas acidophila, preparation methods, and their use in cosmetic and dermal compositions
The invention presents a peptide extract from the microalga Chlamydomonas acidophila for use in cosmetics or dermatology, along with a method for its extraction. The extract is obtained through a process that includes at least one enzymatic hydrolysis step, resulting in a composition containing at least 20% peptides relative to the total weight of the extract.

Alginate catabolic systems in marine bacteria
Brown algae, the second largest group of marine macroalgae, store inorganic carbon as alginate, a key polysaccharide in their cell walls. Marine bacteria rely on alginate as a carbon source, making its catabolism crucial to the marine carbon cycle. This review explores recent advances in bacterial alginate breakdown, potential new metabolic pathways, and future research directions.
