“…Microalgae, which are the natural producers of organic matter and inorganic matter in the aquatic environment, play an important role in stabilizing micro-ecosystems and maintaining healthy water quality in aquaculture ponds (Salam et al, 2016;Esteves et al, 2022). They can absorb carbon dioxide through photosynthesis to produce oxygen and increase the dissolved oxygen levels in the water, as well as purify water by absorbing and transforming excess nutrients (Cheng et al, 2023). To address the negative impacts of unregulated human activities on aquaculture environments, there is growing interest in technology that uses direct artificial culture of green algae to improve the aquatic environment in aquaculture facilities in China.…”

Euchlorocystis marina, a new marine species of the genus Euchlorocystis discovered in 2022, has the potential to improve the water quality in mariculture ponds. However, the effects of salinity on the growth, physiology, and biochemical composition of these algae are not well understood. In this study, changes in physiological and biochemical indices such as cell density, photosynthetic pigment, polysaccharide, and lipid content of E. marina under different salinity treatments were analyzed. The results showed that the highest cell density was observed at a salinity of 15‰. The lowest photosynthetic pigment content was observed at a salinity of 60‰, and the highest polysaccharide and lipid content was observed at a salinity of 60‰. These results indicated that lower salinity was more conducive to E. marina reproduction and growth. E. marina can accumulate polysaccharides and lipids in high salinity environments. This study provides new information for understanding the salinity adaptation strategies of E. marina and has practical significance for its development and utilization.

This article discusses an innovative carbon capture and utilization project from societal, economic, and ethical perspectives. UiT—The Arctic University of Norway and the ferrosilicon producer Finnfjord AS, both located in Northern Norway, collaborate to develop sustainably produced fish feed by cultivating microalgae (diatoms) that feed on CO2 from the factory fume. The microalgae biomass, when added to fish feed applied in the aquaculture industry, contributes nutrients that are essential to human and fish health. The project carries the potential to contribute to the operationalization of the Sustainable Development Goals. The present study is intended as a contribution to the literature focusing on CO2 utilization as a means of achieving a sustainable “green” transition in the industry. By viewing the utilization of CO2 through the lenses of biotechnology, a circular economy, ethics and philosophy, our research findings are relevant to sustainability scholars, industrial actors, and policy makers. It also presents future perspectives on how the aquaculture and manufacturing industries can contribute to the operationalizing of the Sustainable Development Goals in a rapidly evolving industrial environment that is now undergoing a paradigm shift.
