What destructive fishing methods are damaging the reef ecosystem?
While not a problem in Hawai‘i, destructive fishing with dynamite, cyanide and bleach are destroying not only coral, but also the fragile reef ecosystem in other places around the world. Fishing with gill nets and other non-selective methods can lead to over-fishing as well as direct reef damage. Fishermen often say they have no other option if they are to compete with trawlers and other large-scale commercial fishing enterprises. They are also faced with a smaller supply of fish because of chronic over-fishing. These practices generally are indiscriminate and often result in juveniles being killed in the process. With fewer fish reaching reproductive age, populations continue to decline. Q: How does tourism affect the reefs? A: Tourism generates vast amounts of income for key destinations near coral reefs. Responsibly-managed tourism raises awareness about coral reefs and can build support for their preservation. In some places, unregulated tourism can cause damage to the environment
