Close-Up Of A Whale Shark Rhincodon Typus at Oslob Cebu, Central Visayas, Philippines. Feeding. Shrimp (e.g. family Sergestidae) are traditionally caught at night and used for human consumption and as bait in hook and line fishing. The sharks would approach hook and line, trying to feed off the bait, locally known as Uyap. As the sharks interrupted fishing practices, fishermen from the village of Tan-awan, in Oslob learnt to lead them away from the fishing activities by luring them with Uyap. Philippines
