Dear colleagues,

We would like to inform you of our new publication entitled Tragedy of the 
Commons in a Mediterranean MPA: The Case of Gyaros Island Marine Reserve at the 
Journal Sustainability 2024, 16, 1918. The pdf copy is available online via the 
following link https://doi.org/10.3390/su16051918

The article showcases the impact of uncontrolled fishing within the Gyaros 
Marine Protected during the summer of 2022, following the decision by the Greek 
government to open the MPA to small scale fisheries without any form of 
control. One of the key goals for the establishment of the Gyaros MPA in 2019 
is the conservation of one of the most important populations of the 
Mediterranean monk seal, Monachus monachus, in the Eastern Mediterranean Sea.

Abstract:
Gyaros Island (Aegean Sea) is a recently (2019) established MPA in the 
Mediterranean Sea, allowing spatiotemporal small-scale fishing (SSF) activities 
with specific access rules. However, due to the inability of the state 
authorities to establish any fishing permit process, Gyaros MPA initially 
functioned as a No-Take Zone (NTZ), offering a rare opportunity for scientific 
monitoring.
Significant political pressure by fisher organizations led to the opening of 
the MPA in June 2022 without any fishing permit restriction. The unprecedented 
‘race for fish’ that followed led to a significant deterioration of the MPA 
status, as confirmed by scientific monitoring before and after the opening. 
Outcry from national media, based on concerns raised by the scientific 
community and NGOs, resulted in lifting access to fishing in September 2022, 
upgrading Gyaros MPA to a full NTZ. This study aimed to assess if and how the 
MPA functioning was impacted based on a series of experimental fishing trials 
and questionnaire surveys conducted with local fishers. Although a substantial 
part of the fishing community’s mindset is embracing MPAs, our results also 
suggest that the self-interests of a fishers’ minority, along with 
non-science-based policy by the national authorities, have led to overfishing 
and deterioration of MPA status.

To have a more comprehensive perspective of the status of fisheries within the 
Gyaros MPA over the years since its establishment, we suggest that you also 
read the previous relevant article 
https://doi.org/10.1371/journal.pone.0262943, published by colleagues from the 
Hellenic Center for Marine Research (HCMR).

Preliminary results from the fishing experimental surveys which are currently 
continuing within the Gyaros MPA by HCMR, suggest that the fish populations are 
now recovering to the levels prior to the MPA opening.
