B2E presents the tenth edition of Technological Sonar, our monthly selection of noteworthy national and international initiatives in the field of new patents and technologies in the blue bioeconomy sector.

Aquaculture

Use of Microsoft artificial intelligence to increase the productivity of Pescanova’s shrimp aquaculture

Nueva Pescanova, the Spanish seafood company, has developed, in conjunction with Microsoft, the first shrimp aquaculture system equipped with artificial intelligence to improve the productivity, quality, sustainability, and well-being of crustaceans and workers.

Probiotic Bacteria for Fish

A method for increasing the weight and growth rate of fish, preferably salmonids, and for preventing and/or treating microbial infections, comprising the steps of a) adding one or more species of probiotic bacteria to the water, wherein the species of bacteria comprises or consists of *Aliivibrio njordis*, *Aliivibrio balderis*, and/or *Aliivibrio nannie*; and b) exposing the fish to water containing one or more species of probiotic bacteria.

System and Method for Removing and Processing Mortality in Aquaculture

Removing dead fish (known as kills) from an aquaculture cage is of paramount importance. Mortalities occur during almost any growth cycle in aquaculture and, when left in the cage, can begin to decompose, harboring parasites and diseases. Failure to remove dead fish can lead to contamination of the fish stock, and one dead fish can turn into many dead fish, reducing the cage’s profitability. In general, the devices, methods, and systems described herein refer to the automatic removal of dead fish or other mortalities from an aquaculture cage.

Marine Biotechnology

Spirulina used to manufacture a therapeutic antibody against campylobacter

The use of the edible photosynthetic cyanobacterium Arthrospira platensis (spirulina) as a biomanufacturing platform has been limited by a lack of genetic tools. This paper reports genetic engineering methods for stable, high-level expression of bioactive proteins in spirulina, including large-scale indoor cultivation methods.

Trichodermin inhibits oral cancer growth through apoptosis-induced mitochondrial dysfunction and HDAC-2-mediated signaling.

Trichodermin (TCD), a trichothecene first isolated from marine *Trichoderma viride*, is an inhibitor of eukaryotic protein synthesis. Overall, this evidence demonstrates that TCD is a promising new strategy for the treatment of human oral squamous cell carcinoma.
