"@id": "https://www.dolphinaris.com/9-incredible-types-of-dolphins-in-mexico/" [32] With continued illegal totoaba fishing, which is largely motivated by sales to the Chinese market where it is used in traditional medicine, and uncontrolled bycatch of vaquitas, the International Committee for the Recovery of the Vaquita (CIRVA) recommended that some vaquitas be removed from the high-density fishing area and be relocated to protected sea pens. Webestimation of harbor porpoise bycatch but has been applied to bycatch of other small cetaceans and 1 porpoise or dolphin, and 1 marine mammal.
