AQUACULTURE

Systems and methods for improving macroalgae production

This innovation relates to increasing macroalgae production, particularly through the use of microorganisms or holobionts. It includes methods and compositions for beneficial macroalgae holobionts, such as combinations of bacteria that improve growth. These compositions can be in powder or freeze-dried form and may contain bacteria such as Alteromonas and Alcanivorax. They can be applied in aquaculture systems, either in tanks or at sea. The innovation 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 together with andrographic improves its bioavailability and efficacy, allowing for a reduced dosage of amphenicol. This, in turn, decreases residual levels of amphenicol in the harvested animal.

Device for reducing external parasites on fish

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

Innovasea unveils cutting-edge sea bream biomass calculator

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 via a dashboard, eliminating the need for manual sampling. Rigorous testing with Aquafrais Cannes in France has demonstrated up to 95% accuracy and a significant reduction in labor requirements. An algorithm for European sea bass is expected to be released later this year.

Bioactive compounds 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 growing antibiotic resistance and cancer as leading causes of death, marine bioactive compounds have shown great potential in the development of antimicrobial and anticancer compounds. Many are currently in clinical trials and some are FDA-approved. This review explores their sources, mechanisms, and potential in medicine, highlighting their role in advancing healthcare while supporting marine conservation.

MARINE BIOTECHNOLOGY

Modified strains of Chlorella Vulgaris and their production method

Modified strains of Chlorella Vulgaris with a very low chlorophyll content have been disclosed. A method for producing them is also disclosed. The method involves performing mutagenesis on a parental strain of Chlorella Vulgaris. In addition, a composition is disclosed that includes algae biomass derived from the modified strains of Chlorella Vulgaris and its use in food and/or cosmetics, among other applications.

Extracts of Chlamydomonas acidophila, methods of preparation, and their use in cosmetic and dermatological compositions

The innovation presents a peptide extract from the microalga Chlamydomonas acidophila for use in cosmetics or dermatology, together with a method for its extraction. The extract is obtained through a process that includes at least one step of enzymatic hydrolysis, resulting in a composition containing at least 20% peptides in relation to the total weight of the extract.

Alginate catabolic systems in marine bacteria

The second largest group of marine macroalgae, brown algae, store inorganic carbon in the form of alginate, an essential polysaccharide in their cell walls. Marine bacteria depend on alginate as a carbon source, making its catabolism crucial for the marine carbon cycle. This review explores the latest advances in bacterial alginate degradation, potential new metabolic pathways, and future research directions.
