The Dorsal Fin

A report on shark diving tours operating in Oahu, Hawaii suggests that the tours do not result in an increase of risk of shark attacks on humans according to an AP article that appeared at MiamiHerald.com. The report is based on a “snap-shot” study over the course of 4 years, which relied primarily on the logbooks of tour operators and reports from boat operators, which I would expect would draw some criticism from those opposed to shark diving (and likely anybody with some knowledge of research design). The article also mentions that federal fisheries are investigating shark tours in Hawaii on the grounds that they are illegally feeding sharks. Based on the results of the study Galapagos sharks and sandbar sharks were the most prevalent sharks encountered by the shark tours involved in the study. The study also concluded that shark tours “do not increase the potential of shark attacks near the shoreline because the boats operate three miles from the coastline and because the chumming they do to attract sharks to cages mimics the decades-old operations of crab fishing vessels in the same area that discard bait from their traps.”
