Fishing Ban Strives to Protect the World’s Rarest Marine Mammal – National Geographic

The agreement includes a permanent ban on gillnets, in addition to the retrieval of all abandoned “ghost” nets within vaquita habitat. Gillnetting, a vertical netting method used by fishermen, causes vaquitas to become entangled and often drown (even though they aren’t being targeted by the fishermen), and discarded nets remain a continued threat to marine life.
