Oops! What is Bycatch?

Sometimes, when people go fishing for yummy fish to eat, they accidentally catch other sea creatures like dolphins, porpoises, and even big whales! This is called bycatch. It happens when these amazing animals get tangled up in fishing nets or lines, or sometimes they get hooked by accident. It's like accidentally catching a butterfly in a net meant for a ladybug, but for ocean animals!

Why Do They Get Caught?

Fishing boats use huge nets and long lines to catch lots of fish. These nets can stretch for miles! The ocean is the home of dolphins and whales, so they swim near these fishing areas.

Sadly, they can get confused or swim into the nets without realizing it. Sometimes, they might even mistake the fishing lines for food. It’s a tricky situation because the fishing is for food we eat, but it accidentally harms these ocean mammals.

A Sad Surprise for Whales and Dolphins

When dolphins and whales get caught, it can be very scary and dangerous for them. They can get hurt or even drown because they can't get to the surface to breathe air. This is a big problem because there are more and more fishing boats out at sea. It means more chances for these wonderful ocean animals to get accidentally caught. We need to find ways to help them stay safe!

Helping Our Ocean Buddies

Scientists and people who work with fishing boats are trying to find clever ways to stop bycatch. They are inventing special nets that are less likely to trap dolphins and whales, or nets that have ways for them to escape. They are also trying to make fishing practices safer so that fewer sea animals get caught by accident. It’s all about protecting these amazing creatures that share our planet.
