Can vaquitas be saved from extinction?

Question

Accepted Answer

The Survival of the Vaquita Remains Uncertain Despite Recent Sightings

Recent discoveries of six vaquitas in the Gulf of California offer a glimmer of hope for the critically endangered porpoise, but their long-term survival is far from assured. While these sightings confirm that a small population still exists, scientific consensus suggests that fewer than 30 vaquitas may remain in the wild. The primary threat, the use of illegal gillnets for totoaba fishing, continues to decimate their numbers, and past conservation efforts have faced significant setbacks.
Recent Discoveries Offer Limited Reassurance

A scientific expedition conducted between August 19 and September 3 identified six vaquitas, mirroring a similar finding from October of the previous year. These observations, accompanied by photographic and video evidence of the porpoises in pairs near the surface, provide tangible proof that the species has not yet disappeared. Lorenzo Rojas-Bracho, head of the Mexican Vaquita Research Program, described seeing live vaquitas as a relief, underscoring the necessity of continued protection efforts.
Persistent Threats Hinder Conservation Success

The vaquita's drastic population decline is intrinsically linked to the use of gillnets, which are set to catch the also-endangered totoaba fish. The swim bladders of totoaba are highly prized in China, commanding prices of tens of thousands of dollars on the black market, which fuels the illegal fishing that inadvertently kills vaquitas. This persistent demand for totoaba parts creates a continuous incentive for illegal fishing activities within the vaquita's limited habitat.
Past Conservation Initiatives Have Faced Major Obstacles

Conservation strategies aimed at securing the vaquita's future have encountered significant challenges. A notable initiative launched by the Mexican government last year, which involved capturing remaining vaquitas with assistance from US Navy-trained dolphins for relocation to a protected enclosure, was ultimately aborted. This plan was halted after one of the first captured vaquitas died, highlighting the inherent risks and complexities associated with such direct intervention methods.
Extinction Would Mark a Significant Conservation Failure

Should the vaquita ultimately succumb to extinction, it would represent a critical failure for international conservation efforts. As a species listed under Appendix I of CITES, the highest priority category for endangered species, its extinction would be the first such occurrence for a species under this designation since the treaty's inception approximately 40 years ago. This outcome would underscore the profound difficulties in preventing the disappearance of species even with international agreements and high-level attention, such as that provided by high-profile supporters like Leonardo DiCaprio and Carlos Slim.
