Watch: Video of fish jumping out of water caught on camera by fishermen There’s something fishy going on in Stanley – although experts say the phenomenon is entirely natural. A video clip widely shared online shows a huge number of small fish – perhaps tens of thousands – flying out of the water onto the rocky shore near St Stephen’s Beach. A former fisherman identified the species involved as part of the clupeidae genus, a group that includes herrings, shads and sardines. I guessed there might be as many as tens of thousands of them … I’ve never seen this Beachgoer The phenomenon lasted for about 30 seconds and was caught on camera at about 4pm on Sunday. The man who took the video told a Chinese-language newspaper he was watching some anglers with a friend when the silvery fish suddenly jumped out, creating a loud din. “I guessed there might be as many as tens of thousands of them … I’ve never seen this,” he said. Wong Yung-kan, a former agriculture and fisheries sector lawmaker and fisherman, said jumping clupeidae was a seasonal phenomenon occasionally seen from May to August in many parts of Hong Kong, including Stanley, Tolo Harbour and northeastern waters. He said they might be have chased by bigger fish nearby. The low-priced species, with a maximum size of about 12.5cm, are good for making fish sauce or used as fish feed. Local fishermen sometimes used strong lights to attract them at night so they could be caught in large numbers. Wong said he did not see the incident as an omen or something supernatural. In July 2013, a similar incident was seen in waters near the Central piers.
