Wild Vaquita Emergency Conservation

The vaquita porpoise may be the rarest mammal on Earth, with fewer than 10 individuals remaining in the northern Gulf of California, making every individual's welfare critical.

Key Facts

Fewer than 10 vaquitas are estimated to survive as of 2024
The species declined from approximately 600 in 1997 to single digits by the 2020s
Entanglement in gillnets set for totoaba fish (whose swim bladders are illegally trafficked) is the primary cause
CITES Appendix I listing bans international trade in totoaba products that drive the crisis
Mexican government efforts to enforce gill net bans face resistance from fishing communities
A 2017 attempt to capture vaquitas for captive breeding failed when a female died from stress
Acoustic monitoring using click detectors is the primary population survey method
The species has essentially no reproductive recovery capacity given remaining numbers

Welfare Considerations

Vaquitas entangled in gillnets drown within minutes - a rapid but terrifying end for an air-breathing mammal. The extreme rarity of the species means every death has population-level consequences. With fewer than 10 animals surviving, each individual vaquita carries enormous weight for species survival. The 2017 captive rescue attempt demonstrated that stress from capture itself can kill these sensitive animals - limiting intervention options. The vaquita crisis is a welfare catastrophe compounded by the near-impossibility of effective intervention.
