Entanglement
Many rays get entangled in fishing nets. In fact, it happens so frequently that the conservationists believe this species might go extinct. Footage of the friendly beasts can help, and manta tourism is now popular because of the videos.
Tourism
Manta tourism can raise awareness of the manta’s plight, boosting the local economy. Indonesia has actually banned manta fishing, finding that tourism is more profitable. One hunted ray brings in $500, but live animal attractions earn about $1 million within the animal’s lifetime.
