The genus Gracilaria is an economically important group of seaweeds as several species are utilized for various products such as agar, used in medicines, human diets, and poultry feed. Hence, it is imperative to understand their response to predicted ocean acidification conditions. In the present work, we have evaluated the response of Gracilaria foliifera and Gracilaria debilis to carbon dioxide (pCO) induced seawater acidification (pH 7.

Seasonality influences the biochemical characteristics, affecting their ecological and economic values. In the present study, we evaluated pigments, primary and secondary metabolites, minerals, and antioxidant properties of green seaweed growing on the intertidal rocks along the Covelong coast, India, in different seasons (from June 2019 to March 2020).

- Elevated CO2 levels in the atmosphere are causing ocean acidification, which may have unknown effects on seaweed, particularly Ulva compressa.
- A study was conducted under conditions of normal pH and acidified pH, assessing various physiological and biochemical responses, which revealed increased primary productivity and levels of photosynthetic pigments in acidified conditions.
- Although productivity improved and nutritional quality increased in Ulva compressa under lower pH, there was reduced oxidative stress along with a decrease in antioxidant capacity, indicating potential changes to its role in coastal ecosystems and impacts on the food chain.
