Hydrogen Technologies (HT) has developed and tested prototype technology to introduce molecular hydrogen and supplementary oxygen to high density ship seawater holding tanks and land-based salt and freshwater holding tanks and ponds, for coral trout and other white meat finfish.The benefit of the technology is a significant reduction in mortality and an actual improvement in fish health thereby improving yield and grade price/kg of fish sold to market.
A Kyushu University study (2021) estimated there were 24.4 trillion pieces of microplastics in the world's upper oceans or roughly 30 billion 500-ml plastic water bottles. Microplastics are tiny, toxic and very hard to remove from the environment. But researchers in the US have discovered that some Natural Deep Eutectic Solvents (NADES) can attract and bind microplastics, making it easier to remove them from the environment. And the N in NADES is key - natural - in this instance, think extracts from plants. https://www.research.uky.edu/news/researchers-develop-eco-friendly-magnet-battle-microplastics
