What is your invention called?
My invention is called The Dolphin Speaker.

What is the purpose of your invention?
The purpose of the Dolphin Speaker is to save dolphins from getting stuck in the fishermen’s nets.

How does your invention work?
The Dolphin Speaker is a simple mechanism, there's a remote to turn the speaker on so it can play orca sounds. The orca sounds scare the dolphins away from getting stuck in the fisherman's net. Dolphins are afraid of orcas, that is why I chose orca sounds.

What does your invention look like?
This is an example of how the dolphins swim away when the speaker is on.

Name the basic features/components of your invention.
My invention contains an underwater loudspeaker that dolphins can hear from many metres away. There is a long waterproof cable coming for the speaker plugging into any electronic device that plays music. There is an app that plays orca sounds that are specific hunting sounds that scare dolphins.

How do you think you could measure the impact of your project?
To measure the impact I would watch two boats that are going fishing in areas with dolphins, one boat has the dolphin speaker and the other does not. I think that the boat with the speaker would not catch any, but the other one would catch some. However, there are a lot of other things that are killing the dolphins. The Dolphin Speaker will be a step forward.

What are the main problems that inspired your invention?

  1. The main problem is that dolphins are getting stuck in the nets and dying because they can not get air from the surface.

  2. I am sad Dolphins are dying every day.

  3. I would like to keep the ocean full of life.

Why are these problems important to you?
These problems are important to me because every animal counts.

Show us a picture of a waterway close to you that you want to keep clean. What is its name?
I love living next to the ocean, where I see sea life every day like this seal at the Northumberland Strait.

In your opinion, what should other people do every day to help keep the oceans clean?
If your tap is on and you do not need it on, then turn it off so you don't waste water. I also  think that you, your friends and family should not buy tickets to dolphin shows because, in the process, they capture a lot of dolphins, but less than one quarters of the dolphins survive.
