Vaquita on Brink of Extinction Due to Mexican Government's Failure to Enforce Environmental Laws

The vaquita, the world's rarest marine mammal, is on the brink of extinction due to Mexico's failure to enforce its own environmental laws. According to a report from the Commission for Environmental Cooperation (CEC), Mexico's unwillingness to protect the vaquita's habitat has led to the continued use of illegal gillnets, resulting in the near-decimation of the species. The CEC report highlights that despite a ban on certain fishing gear since 2020, fishing activities continue unabated, with fishermen eluding bans by sending their catch to processors in other regions.

Key Takeaways:

• The vaquita population has dwindled to fewer than 10 individuals, according to a 2024 survey.
• The use of illegal gillnets to catch shrimp and totoaba has caused the vaquita's decline, with totoaba being in high demand in Asia due to its purported medicinal value.
• Mexico has failed to provide sufficient information to address enforcement questions, leaving central enforcement questions unanswered.
• Efforts to prevent illegal fishing in the vaquita's habitat, known as the "zero tolerance area," have been successful in recent years, but gillnet fishing remains rampant outside the area.
• The USMCA commission's Compliance Action Plan, imposed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), has seen little progress, with only 10 of the 850 promised satellite trackers installed to monitor small boats fishing in the Upper Gulf.
• The Animal Welfare Institute, Center for Biological Diversity, Natural Resources Defense Council, and the Environmental Investigation Agency have petitioned the USMCA commission to investigate Mexico's failure to enforce its fishing and trade laws.

Statistics:

• Fewer than 10 vaquita remain, according to the 2024 survey.
• 41 acoustic encounters with vaquita were recorded in the porpoise's habitat using hydroacoustic devices this summer.
• 850 satellite trackers were promised to monitor small boats fishing in the Upper Gulf, with only 10 installed as of June.
• Mexico was required to implement new regulations and enforcement measures by 2023 under the CITES Compliance Action Plan.
