The Dory dilemma, conservation fears from a movie

The video discusses the impact of the movies Finding Nemo and Finding Dory on the demand for clownfish and blue Tang as pets. After Finding Nemo, the demand for clownfish increased, leading to overfishing and local extinctions. While clownfish can be bred in captivity, blue Tang cannot, posing a conservation challenge. The video highlights the difficulties in breeding blue Tang and the harmful methods used to capture them in the wild. Conservationists are working on breeding blue Tang in captivity, and the video suggests alternative fish for aquariums.

What was one of the consequences of the movie Finding Nemo on clownfish populations?

• Increased interest in marine biology

• Clownfish became the most popular aquarium fish

Why is breeding blue tangs in captivity particularly challenging?

• They require a specific water temperature

• They are aggressive towards other fish
