Salmon Conservation and Genetic Diversity

What was the estimated number of coho salmon returning to California streams 75 years ago?

• 100,000

• 200,000

• 300,000

• 400,000

Which of the following is NOT a reason for the decline in salmon populations?

• Overfishing

• Water diversion

• Building of dams

• Increased water quality

What is a unique feature of salmon's life cycle?

• They are born in the desert

• They migrate over 1000 miles

• They live in trees

• They never leave the ocean

What is the main goal of the DNA sequencing program for salmon?

• To maximize genetic diversity

• To change the color of salmon

• To increase the size of salmon

• To reduce the number of salmon

How are young salmon collected for the DNA sequencing program?

• By fishing in the ocean

• By capturing them in rivers

• By collecting them from fish markets

• By breeding them in labs

Why is genetic diversity crucial for the survival of salmon?

• It helps them grow faster

• It prevents inbreeding and increases fitness

• It makes them taste better

• It makes them more colorful

What is the potential consequence of inbreeding among salmon?

• Longer lifespan

• Deformities and disease vulnerability

• Increased size

• Faster swimming

What role do salmon play in their ecosystems?

• They are a type of bird

• They are a type of plant

• They are a vital food source and nutrient provider

• They are a primary predator

What is the ultimate goal of the salmon DNA program?

• To increase the population to original numbers

• To change the migration pattern of salmon

• To make salmon a popular pet

• To eliminate salmon from the ecosystem

How can people contribute to salmon conservation efforts?

• By eating more salmon

• By planting more trees

• By supporting conservation organizations

• By avoiding rivers
