Vaquita

Vaquita surfacing in water
Species
Phocoena sinus
IUCN Status
Critically Endangered

Gillnet fisheries pose the greatest threat to the vaquita population. Current bycatch estimates are unavailable, but in the early 1990s an estimated 39 to 84 individuals were caught by fishermen from one town (D'Agrosa et al 2000).  In 2014, CIRVA reported that probably only 100 individuals remain of this species, and the population was projected to continue declining without emergency regulatory action by the Mexican government (CIRVA, 2014). By 2019, only ~19 individuals are estimated to remain. Recent surveys indicate a population low of ten individuals .
