While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food. Under farming conditions where most of abalones are produced, the macroalgae are the main abalone feed. However, many abalone farms use successfully high quality manufactured feed which has been found healthy and efficient in the production of high-quality

885 wahoo’s were examined and 53% of the wahoo had food containing primarily pelagic fish and squid. The most occurring food was frigate mackerel (Auxis thazard), porcupinefish (Diodon hystrix), and the flyingfish (Cypselurus spp.) (Manooch, 1983). They have also been recorded feeding on tunas, little tunny, dolphinfish, herrings, jacks, lanternfishes, scads, and pilchards. Even though wahoo is attracted traveling closely to floating debris or plants, such as sargassum spp., their diet makes them go out into the open waters and find food there.
