Please answer the following question: Off the coast of Hawaii's Big Island swim masses of colorful tropical fish. Some of these fish will be caught and sold, ending up in aquariums around the world. Is the industry putting populations of the fish at risk? Scientists who have studied the Big Island fishery say it is well managed. Rules put in place more than 15 years ago have helped to protect the fish. Along 35% of the coastline, for example, fish collecting is banned. Two years ago, the state cut the number of fish species for the aquarium trade from hundreds to just 40. Conservationist Robert Wintner objects to the findings. Wintner, who owns snorkel shops across Hawaii, started the Snorkel Bob Foundation to protect the island's coral reefs . He says he simply doesn't see yellow tang in the protected areas. "There should be millions of them," he says. "Where are they?" Wintner says people believe the numbers in reports. But few people have actually dived into the coral reefs to see for themselves how many fish can be found there. According to Wintner, the coral reefs along the coast should be filled with yellow tang, but they are "virtually empty". Empty reefs are not good for tourism, Wintner points out, which brings out $800 million yearly. By contrast, the aquarium-fish trade brings out just $2 million yearly.
