Methods such as Cyanide Poisoning, Dynamite Fishing, Bottom Trawling and Long-line Fishing are still widely practiced for catching large amounts of fishes. These practices affects the marine life adversely. Blasting kills coral reefs and animals that live around them. It destroys 200 square feet of coral reef at a time while cyanide stuns fishes for them to be easily caught as they are unable to escape. It is estimated that, over the past 25 years, the damage caused by dynamite fishing to reef ecosystems has resulted in the loss of US$3.8 billion dollars of income to Indonesia. Therefore, though these are short term gains, it results in large and severe compensations in the long run.
