B2E presents the fourteenth edition of Technological Sonar, our monthly selection of national and international initiatives to watch, focusing on new patents and technologies in the blue bioeconomy sector.

Aquaculture

Smart Aquaculture System Using a Mobile Camera

This work designs and implements a unique IoT-based aquaculture monitoring system. Wi-Fi and internet are combined in this system for convenience. The work demonstrates better results at a lower cost compared to other available systems. Aquaculturists can now avoid time-consuming manual testing.

Driving Seaweed Success in Ireland

In three years, Ireland’s Pure Ocean Algae has domesticated a wild “dulse,” a red algae species, and created a fully developed macroalgae value chain. Fish Site spoke with founder Michael O’Neill to learn more about their processes and Ireland’s potential as a global seaweed hub. In The Fish Site.

Marine Living Resources

Biomaterials and bioactive natural products from marine invertebrates: from basic research to innovative applications

In this review, we analyze the literature from 2010-2019 on natural products (bioactive molecules and biomaterials) from the main phyla of marine invertebrates explored to date, including sponges, cnidarians, mollusks, echinoderms, and ascidians, and present relevant examples of natural products of public and private interest.

Marine compounds for melanoma treatment and prevention

In this review, we report marine compounds from micro- and macro-organisms with in vitro and in vivo activities against melanoma, including the compound Marizomib, isolated from a marine bacterium, currently in phase III clinical trials for melanoma. When available, we also report active concentrations, cellular targets, and mechanisms of action of the mentioned molecules. Furthermore, compounds used for UV protection and melanoma prevention from marine sources are discussed.

Could algae and fish waste be the next flexitarian superfoods?

A new project aims to produce hybrid food products that combine seaweed, microalgae, insect meal and/or fish by-products with protein-rich plant ingredients. Key by-products being examined include fish heads and bones that are otherwise discarded or used in low-value food products. Researchers will also attempt to improve the texture and nutritional profile of plant-based products by adding seaweed, microalgae, and insect larvae – raw materials that are at the base of the food chain or would otherwise be wasted.

Processing of organic matter in a simulated offshore wind farm ecosystem under current and future climate and aquaculture scenarios.

This study investigates the combined pressures of climate change and the planned co-location of offshore wind farms (OWFs) and aquaculture zones on the carbon flow through epifaunal communities inhabiting wind turbines in the North Sea.
