Many thanks to all co-authors for their huge contribution to this work! 🎉😀🙌

Although measures restoring commercial fish biomass could yield carbon benefits comparable to mangrove restoration 🌳, significant knowledge gaps and uncertainties remain and prevent their inclusion in the nature-based climate solution portfolio! ❌⛔
8/9

❓ This leads to the following question: Can the restoration of fish populations promote carbon export and sequestration to mitigate climate change 📈?
7/9

🎣🌡️🌍 Combined with climate change (under SSP 5-8.5), maintaining today's fishing levels will further decrease commercial fish carbon export by 56.7% compared to the 1950s 📉.
6/9

🎣 Fishing has already reduced commercial fish carbon export by 47% compared to the 1950s. Every 1% decline in biomass due to fishing will decrease fish carbon export by 0.8%! Again, size matters as size-related (📏) mechanisms linked to fish metabolism are at work!
5/9

With every degree of warming, commercial fish biomass and carbon export will decrease by 4.2% and 2.5%, respectively. This shows that mechanisms related to fish size (📏) and temperature (🌡️) are at work, partly offsetting the direct impact of a decrease in biomass ⚖️!
4/9

🌡️🌍 Climate change is projected to decrease fish carbon export by 4% under SSP 1–2.6, and 13.5% under SSP 5-8.5 by 2100, relative to the 1990s 📉.
3/9

We show that in 1950, before the development of industrial fisheries, commercial fish exported 0.23GtC.yr, mostly through the sinking of their fecal pellets 💩, but also through the sinking of their dead carcasses 💀.
