Dynamite vs Cyanide Fishing: What's the Difference?

Updated on April 16, 2013

"A society is defined not only by what it creates, but by what it refuses to destroy."
- John Sawhill


It is everyone's responsibility to protect and help take care of our oceans and the marine life it holds. Learn more about Dynamite and Cyanide fishing - its difference and major effect to the marine environment.

Dynamite and Cyanide fishing are both methods of collecting live fish and is an illegal activity that mankind is doing on our seas to just easily catch fish.

The once beautiful marine environment under the sea was ruined by man's greed and laziness.

Instead of using the typical conventional hooks and nets, they used bombs and cyanide poisons to kill fishes.

Unfortunately, the coral reefs and other sea creatures which are not their purpose to capture are also involved on this destructing activity.


Let us take a closer look on what is dynamite and cyanide fishing is all about and its effect to marine environment:


Dynamite Fishing or Blast Fishing:

Dynamite fishing uses bombs to set under water to kill school of fish and for their easy collection. A typical home-made bomb would include ammonium nitrate; substance normally used as fertilizer.

The dead fishes floating on the water will then be scooped out, and the marine environment underneath was totally destroyed leaving it dead and devoid of life.

The fishes are killed by shock waves caused by the blast; the corals were also damaged and broken into pieces.

The blasted areas caused by explosives are very slow to recover especially the formation of corals because of difficulty establishing on loose substrate.

Cyanide Fishing or Poison Fishing

Cyanide fishing, on the other hand, uses sodium cyanide mixture to stun the fish; they spray this poison on the individual layers of the coral reefs.

The caught fishes are mainly used for the supply of the growing market for aquarium fishes.

This practice does not only involve the target population but also on the nearby coral reefs and other marine organisms that are very important on the cycle of food chain.

How does cyanide poison affects marine population?

The cyanide concentration really slows photosynthesis in zooxanthellae, the unicellular algae resides on corals, sea anemones, sponges, mollusks and jellyfishes which translocate the products of photosynthesis to the host.

So when this happens, the coral reefs lose their colour and may eliminate their major food source.

Another thing, the sodium cyanide, when broken down into sodium and cyanide ions, can block the oxygen-transporting haemoglobin on fish thus oxygen is prevented from reaching the cells.

Some small fishes that can’t take a high dosage of this poison dies in the process. So imagine how many species living on a particular population of underwater environment.

These two illegal practices are the major threats in the marine population and coral reef ecosystems.

It will highly contribute to the decline in marine species and the very slow recovery of coral reefs.

The blown up coral reefs will again take years to form; making the area damaged and lifeless.

We know that the government banned these practices in order to save and protect our marine environment. But people are just too selfish and lazy to do their share in reducing the planet's major issues on marine environment.

They only want to take and take what's the underwater world has to offer and not thinking of caring it for future use again.

What is important to them is today, that they can make more money and sell a heavy catch.

So what about tomorrow?

If you think that a small area wouldn’t harm the world, think again. If more and more people will think that way, summed it up and you will get a whole ratio. Even small things can contribute to a big change.

So when these things happen, there will be death all over the place...

thus making it hard to imagine that the once beautiful underwater nature...

not all too long ago, used to be like this:

There is enough in this world for man's needs, but it can never satisfy man's greed. Let us all be aware of the consequences of own actions. We know what is the right thing to do.

I am spreading this word for the sake of your and my future generations. We owe this world to them.

Let us protect and help save marine environment.

      Hello rosepetals, yes, there are still some fishermen who practiced these kind of fishing. we used to buy fish in fish stores too and take care as pets, bought aquarium and stuffs. but fish didnt last long. they die one by one.

      I did not know this was still practiced. I know it's illegal to do and when I was little I had a salt water fish tank. My mom and I went to the fish store to get a new fish and when we introduced it to the tank everything seemed ok until the next day. I woke up to all the fish in the tank were dead. My mother took a water sample to the fish store to see what had happened. The owner of the fish store said it was cyanide poisoning. I never had salt water fish again. I was traumatized by the blowing up reefs to get the stunned fish for entertainment purposes. Great article Voted up!!

      A terrific write exposing what man is doing to satisfy his greed. Man has created all the turmoil in this world. And he is going to suffer the effects of his actions.

      It is high time we not only thought about protecting our land environment but also our marine environment.

      Voted up, useful, interesting and shared, here and on G+1.

      Thanks for providing such a wonderful information.It is very disturbing to know that Fish catcher uses these types of methods in order to gain maximum profit from less effort.I think general awareness is required among the people to tell them how harm these method would be not only for our sea environment but also for the people who are consuming these fishes.

      Thanks(Voted UP)!!

      Dynamite and cyanide fishing are terrible ways to catch fish. What a horribly destructive way to treat the environment! Thank you so much for publicizing this information, unknown spy.

      Very sad that some people still use destructing and dangerous practices in catching fish. Education and counseling are badly needed to stop them and make them have concern in sea environment protection.

      our government here Peggy..it was illegal to do such activity because of the effects on the marine life. some places here, you have to pay a fine when caught.

      Hi Mycee! This is really true. I saw once on TV about people who are doing this and they just explained that it is easier.

      Your hub is a good way of telling these people to stop doing it and do fishing in the right way.

      Voted up and more!

      Have a nice day. :-)

      Hi my friend M., this is so sad a such a shame that this type of thing goes on daily, greed and laziness drive them on to recklessly and mindlessly destroy the sea and sea life. These are the types of people that only care for themselves and nothing else . Well done !

      Vote up and more !!! SHARING !

      Absolutely correct, Mycee. It is purely greed that causes this. When it is gone, it will never be recovered again.

      You stated..."We know that the government banned these practices in order to save and protect our marine environment." Which governments? If the whole world is not on board with banning practices like this, our oceans will definitely suffer. I had no idea such things were even happening. Hopefully the people doing this type of thing will wake up and realize the long term consequences.

      This practice makes me so angry! I've heard of it being done here in Peru, and it's only the greedy who would do such a thing. The average fisherman loves the sea and wants to protect it, not destroy it and leave it lifeless. Your last two photos are especially touching. Thanks so much for bringing this to our attention and for the call to action, unknown spy!

      Long ago I went "fishing" with a couple of guys who taught me telephone fishing. They had an old crank telephone with a couple of wires. Stuck one down in the water out one side and one out the other side and started cranking. Took a while but eventually a few stunned white bass rose to the surface for netting. Only good news is the process is so inefficient that only young idiots like us would try it.

      You have raised a very important point here. The need of the hour is that we should realize the amount of harm that is being done to gain some benefits. Thanks for sharing your word over an issue that needs to be addressed soon.

      Myz, I must be a bit naive, but didn't realize these two things were even occurring to capture and kill fish. Very informative and so true that this indeed is not right and thank you for bringing this out in the open and hope that something can be done to stop these practices. Have voted and shared too!!
