Dynamite fishing

  1. 1. Dynamite Fishing
  2. 2. Dynamite Fishing <ul><li>also known as blast fishing </li></ul><ul><li>the practice of using explosives to stun or kill schools of fish for easy collection </li></ul><ul><li>this practice is illegal and often ruins and causes destruction to the ecosystem and their habitat (e.g. corals, reefs) </li></ul><ul><li>this may also cause injuries and accidents for fishermen </li></ul><ul><li>the practice of dynamite fishing remains widespread in Southeast Asia, parts of Greece and Coastal Africa </li></ul>
  3. 3. Why people engage in dynamite fishing <ul><li>Poverty </li></ul><ul><li>Lack of job opportunities </li></ul><ul><li>Ignorance </li></ul><ul><li>Laziness and greed </li></ul><ul><li>Lack of discipline </li></ul>
  4. 4. Poverty <ul><li>Poverty is a major problem in our country today. Because of poverty, people living near the sea or those who make fishing their source of living resort to desperate measures to augment their income. Engaging in dynamite fishing is one of these “desperate measures.” </li></ul>
  5. 5. Lack of job opportunities <ul><li>Dynamite fishing is an alarming phenomenon because of its adverse effects on the ecosystem. But some people say they cannot avoid engaging in the practice because there are no other job opportunities for them. Some fisherfolk say it’s better to go to the sea and using dynamites than doing nothing at all. </li></ul>
  6. 6. Ignorance <ul><li>Many people are not aware of the consequence of their use of dynamites in fishing. Others do not care. Many think only about the money, forgetting about the effects of what they do to their environment. </li></ul>
  7. 7. Laziness and greed <ul><li>There are some people who are educated, who have the money, but are lazy and greedy. They want easy money, so they resort to the use of dynamites. Greed also drives people to use the illegal method so that they will more catch in a short period of time. </li></ul>
  8. 8. Lack of discipline <ul><li>Among all these reasons, lack of discipline is the most important. It doesn’t really matter if a person is poor, uneducated, or there is no opportunity for work. What is important is they have discipline. There might be no jobs, but they can still catch fish by using other means. </li></ul>
  9. 9. Process
  10. 10. Making the fuses <ul><li>The fuses are designed to burn underwater. The aluminum part is a blast cap, which ignites the ammonium nitrate and causes the explosion. These fuses are difficult to obtain and are the most expensive part of these explosive charges. </li></ul>For demonstrational purposes
  11. 11. Making the fuses <ul><li>Bottles are filled with the inflammable fertilizer. An ordinary bottle of gin (0.3l) usually does the job, but unfortunately gallon-size containers are often used too. </li></ul>For demonstrational purposes
  12. 12. Making the fuses <ul><li>The fuse is wrapped to a matchstick and pushed into a bottle. The water-tight seal is cut out of common flip-flops. </li></ul>For demonstrational purposes
  13. 13. Fishing <ul><li>With the charges prepared, the fishers go to sea, where they look out for spots at which schools of fish can be found. When a good spot is located... </li></ul>For demonstrational purposes
  14. 14. Fishing <ul><li>The fuse is lit with a matchbox, ready to be thrown to sea... </li></ul>For demonstrational purposes
  15. 15. Fishing <ul><li>The “dynamite” is then thrown into the sea. </li></ul>The fuse was thrown over a fishless area
  16. 16. Fishing <ul><li>Immediately after the blast, the hookah-diver gets ready to descend. He is equipped with an old-fashioned, leaking mask and his air supply comes from a hose (commonly used for aquarium pumps), which is connected to a compressor on the boat... </li></ul>That guy is just playing the role of a dynamite fisher/diver
  17. 17. Fishing <ul><li>... his weight belt is a rock that is fastened around his waist in an old T-shirt and his fin is made of plywood. </li></ul>That guy is just playing the role of a dynamite fisher/diver
  18. 18. Fishing <ul><li>Meanwhile, below the boat, dozens of blasted fish sink to the sea bed... </li></ul>That dead fish was bought from the local market
  19. 19. Fishing <ul><li>The diver goes below to collect all the dead fish. </li></ul>Those dead fish were bought from the local market, thrown to the sea for the demo-diver to pick-up
  20. 20. Fishing <ul><li>The seascape was wasted... </li></ul>That dead fish was bought from the local market
  21. 21. Other illegal methods of fishing
  22. 22. Cyanide Fishing <ul><li>Fishermen stun fish by squirting cyanide into the reef areas where there are fish. They then rip apart the reefs with crowbars to capture disoriented fish in the coral where they hide. </li></ul><ul><li>In addition, cyanide kills coral polyps, algae and other organisms necessary for healthy reefs. </li></ul>
  23. 23. Muroami <ul><li>This uses an encircling net with pounding devices consisting of heavy cement blocks. The pounding devices are repeatedly and violently lowered into the area encircled by the net, literally smashing the coral in that area into small fragments in order to scare the fish out of their coral refuges. </li></ul>
  24. 24. STOP BLAST FISHING! <ul><li>Blast fishing is one of the more pervasive threats to coral reefs in the world today. Let’s help stop blast fishing in our own small way. </li></ul>
