Experts estimate that recent sightings indicate there are between 10 and 13 individuals remaining, a figure similar to the 2021 expedition.
Specialists have warned that they cannot live or reproduce in captivity.
Each block weighs two to three tons and has a pair of 2.5-meter-long hooks with inward-bent tips to trap and tear fishing nets, according to the Environmental Impact Statement (MIA) of the 2022 project.
Semar stated that Barbara Taylor, leader of the observation cruise, considered this measure to be the first action by the Mexican government that has genuinely created a sanctuary for the vaquita marina due to the significant reduction in vessels and gillnets.
According to the agency, the first of two stages to expand the project began on August 30, following the recommendation of researchers who participated in the expedition.
They will place 64 structures along the perimeter of the Zo and to the south of it. Later, they plan to plant another 152 in those areas where specialists have registered the presence of vaquita marinas, both visually and through acoustic detection.
The expansion of the project is subject to compliance with current regulations.
The 2022 MIA indicates that a water quality monitoring program will be established, along with one for phytoplankton, zooplankton, and the recovery of nets trapped on the blocks to prevent the drowning of mammals and birds.
As in the previous year, the crews of the “Sagitario” and “Virgo” buoy-laying ships will be responsible for placing the 216 blocks on the seabed using cranes.
