What is cyanidefishing?
Cyanide fishingitself is fairly simple: Fishermen first crush cyanide pelletsinto makeshift squirt bottles filled with seawater. Then theydive down coral formations and squirt the cyanide solution intothe crevices where fish hide . The cyanide stund the fish, makingthem easier to capture.
How can cyanidefishing harm coral reefs?
Sometimesfishermen have to use crowbars to pry coral heads apart andretrieve the stunned fish, and cyanide would also kill the coral.

Scraping
Scrapers Dragging a net along the sea floor is one of the mostcommon forms of fishing around the world. Bottom trawling catchesfish and shrimp easily, but it disrupts the complex communitiesof plants and animals, many of them very small or hidden in thesediment, that live on sandy and muddy sea floors.
Trawlers often scrape the same area several times each year.Sea-floor species can be displaced, and the types andavailability of nutrients changed. Sediments whipped up bytrawling can make water a thousand times cloudier than normal,limiting resettlement and feeding of plants and animals
