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 2019, CIRVA reported that probably only 10 individuals remain of this species, 22 at most. (CIRVA, 2019).
