Vaquitas have been drowning at alarming rates in gillnets for shrimp and finfish. The government of Mexico banned gillnet fisheries; however, the vaquita porpoise continues to be a victim of bycatch, due to illegal fishing for the totoaba. The swim bladders from the totoaba fish are highly valuable in Chinese markets. Along with the totoaba and masses of other marine life, vaquitas get entangled in these nets and drown.
