In the Gulf of California, Illegal Fishing for Totoaba, An In the Gulf of California, illegal fishing for totoaba, an endangered fish whose swim bladder is prized in China for its purported medicinal properties, has forced another species, the vaquita porpoise, to the edge of extinction. 52 WILD HOPE A TALE OF TWO SPECIES BOGLE SEAN BY PHOTOGRAPH WH__Mag17_Vol3_Pgs_CC.indd 53 1/23/17 10:08 AM Wild Lens, a wildlife conservation media company, has just released the first installment of Souls of the Vermillion Sea, a documentary about the vaquita’s plight and the efforts underway to protect it.

History and fishing ban The totoaba (Totoaba macdonaldi) is distributed in the most important and productive fishing zone in Mexico (Gulf of California). In 1920, the fishing of this species influenced the establishment of fishing villages in the Upper Gulf, but it was until 1929 that it was commercially exploited, increasing fishing to 2,000 tons per year between 1940-1950, for meat consumption. In 1955, the government of Mexico established a seasonal ban to protect the breeding areas in the critical stages (mouth of the Colorado River); in 1974, this area was decreed a Reserve for the species subject to fishing.

Fishery-induced changes in the life history of exploited marine fishes, such as truncated size and age structure, local extirpations, reductions in age at maturity, and changes in mortality patterns, have occurred. In the present study, we explored life history aspects of totoaba Totoaba macdonaldi, almost 40 yr after a population col- lapse, to examine whether totoaba maintained their life history pattern and to identify the poten- tial threats of using fishing gear (hooks, gillnets). The results of the present study indicate that the totoaba size structure was not truncated as expected in overexploited populations; indeed, it was similar to that observed in the past.

  • Re: Mexico's New Fishing Regulations Applicable to CITES Totoaba And
    Via Electronic Mail April 1, 2021 Re: Mexico’s New Fishing Regulations Applicable to CITES Totoaba and Vaquita Decisions 18.292-18.295 Dear Secretary-General Higuero, On behalf of the Animal Welfare Institute, Center for Biological Diversity, the Natural Resources Defense Council, and the Environmental Investigation Agency, we write to provide information regarding new fishing regulations issued by Mexico to protect vaquita and totoaba in Mexico’s northern Gulf of California and Mexico’s continued enforcement failures. As detailed below, Mexico’s new regulations, published on September 24, 20201 and supplemented in January 2021, potentially offer the vaquita and totoaba important, new protections and are a substantial improvement from previous regulations. However, key components of the regulations remain unimplemented, and illegal fishing continues—a familiar pattern, as the Mexican government has a long history of issuing but not enforcing regulations. The IUCN recently described illegal fishing as “uncontrolled,” and the Mexican government is considering shrinking the area in which gillnets are currently banned. The Mexican government has not yet demonstrated that the vaquita and totoaba are effectively protected. Mexico’s continued failure to address the ongoing fishing and trade of totoaba and ongoing critical endangerment of the vaquita violates the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Accordingly, we urge the Secretariat and Standing Committee to formally initiate compliance procedures under Resolution Conf. 14.3 and recommend sanctions against Mexico for its continued violation of CITES, to be discussed at the 73rd Standing Committee virtual meeting this spring, or no later than the Standing Committee meeting scheduled for September 2021.
