Philippine Dynamite Fishing http://cebuexperience.com/262/living-in-cebu/cebuano-culture/cebu-city-fisherman-blows-himself-up/ Blast fishing or dynamite fishing is the practice of using explosives to stun or kill schools of fish for easy collection. This often illegal practice can be extremely destructive to the surrounding ecosystem, as the explosion often destroys the underlying habitat (such as coral reefs) that supports the fish. The frequently improvised nature of the explosives used also means danger for the fishermen as well, with accidents and injuries.
Dynamite fishing or blast fishing is the use of bombs to kill or hurt lots of fish at once. This makes the fish easier to catch. It is bad because it can kill lots of fish and damage where they live. It can also hurt the people fishing. It is illegal in a lot of places.
The bombs make the fish's gas bladder explode and stun them. Some of them float at the surface of the water, but a lot sink to the bottom.

Impact on coral reefs
Coral Reef
Researchers believe that destructive fishing practices like blast fishing to be one of the biggest threat to the coral reef ecosystems. Blown up coral reefs are no more than rubble fields. The long-term impact associated with blast fishing is that there is no natural recovery of the reefs. Coral reefs are less likely to recover from constant disturbance such as blast fishing than from small disturbance that does not change the physical environment. Blast fishing destroys the calcium carbonate coral skeletons and is one of the continual disruptions of coral reefs. In the Indo-Pacific, the practice of blast fishing is a main cause of coral reef degradation. As a result, weakened rubble fields are formed and fish habitat is reduced.
The damaged coral reefs from blast fishing lead to instant declines in fish species wealth and quantity. Explosives used in blast fishing not only kill fish but also destroy coral skeletons, creating unbalanced coral rubble. The elimination of the fish also eliminates the resilience of the coral reefs to climate change, further hindering their recovery. Single blasts cause reefs to recover over 5–10 years, while widespread blasting, as often practiced, transforms these biodiverse ecosystems into continuous unstable rubble.
Effects of dynamite fishing: * NATURE
1. Destruction of the coral reefs.
Once a fisherman throws a dynamite to the sea there is a great possibility that they might hit a coral reef. Coral reefs serves as a breeding place and gives protection to the baby fish. So, if the remaining coral reefs are destroyed we might encounter a seafood shortage and some fishermen might lose their jobs.
2. More endangered marine species.
In the past years we have lots of fishes in our seas but because of this illegal activities many fishes are now endangered. Because most of the coral reefs in our country are destroyed, fish loses the place where they could reproduce. We will definitely lose a lot in our resources if this kind of activity will continue in the next years.
Some endangered marine species: * Turtle http://www.swaptravel.org/userimages/rt_leatherback_turtles_070712_ms.jpg * Blue Whale http://myanimalblog.files.wordpress.com/2008/02/blue_whale.jpg * Sperm Whale http://www.sailingissues.com/dolphins/sperm-whale3.jpg * Steller Sea lion http://www.travel-vancouver-island.com/data/media/3/steller-sea-lion_143.jpg * Humpback Whale http://www.specieslist.com/images/external/Humpback_Whale_underwater.jpg
3. Sea creatures
Fish and other aquatic animals are very sensitive to these chemicals. Most of them reduce their swimming abilities.
Other effects includes delayed mortality and altered growth patterns.

* HUMAN
1. Toxic to the human body
Some of the chemicals used in making dynamites are not good for the human health. That’s why the government doesn’t allow this kind of fishing method because their coulod still be small traces of those chemicals which could cause some health problem to our body.
2. Loss jobs
For the past years we could observe that there are lots of fishes in our seas. But today the number of fishes caught by the fishermen become less. So, if this method would not be stop, then, lots of fishermen might lose their jobs and this could add up to the problems our country is facing today.
