A survey took place between October 17 and November 3, 2021 to estimate the number of unique vaquitas (including the numbers of unique calves) seen in the Zero Tolerance Area (ZTA). The Government of Mexico agreed to strictly enforce a region-wide ban on fishing with gillnets within the ZTA where the remaining vaquita are concentrated. Most of the 2021 surveys were conducted in this area. Two ships (the R/V Narval with ship height of 7.7m and the M/V Sharpie with ship height of 8.1m) used experienced observers to find and track vaquitas.
