Dive guide Scares Puffer fish to get it to puff up

This video was shared to DIVE.in on our Facebook page with a question, if this was dangerous behavior.

When I saw this I got so angry, not on the person who shared it, but on the dive guide. He clearly wanted to put on a show for his guests, and therefore decided to use this porcupine puffer fish as his entertainment props.

We earlier covered a related topic where a new dive guide didn’t know how to behave towards dive guests with this behavior: You can read and join the discussion here: The Bad Diver and Aquatic Awareness

The worst dive behavior

I’m really sad to share a video like this, but I feel it’s the only way to stop a behavior like this.

It’s a bad practice to touch anything underwater, but to deliberately chase and catch a puffer fish is just cruel. You can also read our guide on becoming a sustainable diver.

Do Puffer fish die when they puff up?

The biggest concern is actually what happens to the puffer fish when the dive guide makes it blow up.

When a puffer fish puffs up, it takes in water to increase the size. This makes the puffers organs move to the side, inside the body and the organs flattens. This causes an extreme stress to the puffer fish. In some cases the puffer fish dies from this stress.

What would you do in this case?

Have you ever seen a diver touch or harm underwater life? What did you do to stop it?

Often divers don’t know what harm, the touch of humans does to marine life, we as divers have a responsibility to share our knowledge, and stop the ones destroying our environment.

Spread the word and let’s have an ocean worth diving in a decade!

    This (dive guide) should be sacked ,This would not happen in Maldives,Red sea etc,more common in afro Caribbean countries where standards tend to be way below the acceptable levels of underwater etiquette

      Is this really regular behavior in those countries? How can people, who works with diving, do this. I can imagine anyone I know doing this.
