Predators that feed on stone crabs include horse conch, grouper, sea turtles, cobia, and octopuses. These predators include; cobia, bull sharks, and sandbar sharks, as well as humans. The cobia feeds primarily on crabs, squid, and fish. Wild cobia broodstock are captured by professional fishermen. Later cobia juveniles can be raised in ponds or shallow, near-shore submerged cages. The cobia is frequently parasitized by nematodes, trematodes, cestodes, copepods, and acanthocephalans. The cobia resembles its close relatives, the remoras of the family Echeneidae. To address these impacts, the WWF is creating the Seriola and Cobia Aquaculture Dialogue (SCAD). Rearing cobia larvae at salinities as low as 15 ppt is possible. "Cobia" reached Pearl Harbor from New London 3 June 1944. Around 80% of marine cages in Taiwan are devoted to cobia culture. Currently, around 80% of marine cages in Taiwan are devoted to cobia culture. The mature cobia has a forked, slightly lunated tail, which is usually dark brown. A survivor from the yacht was rescued as "Cobia"'s first prisoner of war. Surfacing to photograph her sinking victim, "Cobia" was driven under by a Japanese bomber.
