Ocean Acidification and Aquacultured Seaweeds: Progress and Knowledge Gaps

This systematic review aimed to synthesise the existing studies regarding effects of ocean acidification (OA) on seaweed aquaculture. Ocean scenarios may increase productivity aquacultured seaweeds, but this depends species-specific tolerance ranges. Conversely, be reduced, with ensuing economic losses. We specifically addressed questions on: how seaweeds acclimatise an in oceanic CO2; OA photosynthetic rates and nutrient uptake; knowledge gaps mitigation measures for farming environments. Articles were searched by using Google Scholar, followed Scopus Web Science databases, limiting publications from 2001 2022. Our revealed that, among all OA-related macroalgae, only a relatively small proportion (n < 85) have examined physiological responses seaweeds. However, it is generally agreed that these cannot when critical biological systems are compromised. The approaches unbalanced overly focused monitoring cultivation methods. Future work should emphasise effective implementable actions against while linking changes production costs profits.
