Catch-and-release fishing may be harmful to fish

The video discusses the impact of the catch and release method on fish, specifically how it affects their ability to capture prey. Scientists from UC Riverside conducted a study using Shiner perch, capturing some with hooks and others with nets. Observations showed that fish with mouth injuries had difficulty sucking prey into their mouths due to disruptions in the suction feeding system. This disruption creates negative pressure in the mouth, hindering the fish's ability to feed effectively.

What is a potential consequence of the catch and release method on fish?

• Improved ability to capture prey

• No effect on fish behavior

• Impaired ability to capture prey

• Increased fish population

What was the purpose of the UC Riverside experiment?

• To increase fish population

• To develop new fishing techniques

• To observe the effects of different capture methods on fish feeding

• To study fish migration patterns

How were the Shiner perch captured in the experiment?

• Using a spear

• Using a hook and line and a net

• Using a fishing rod

• Using a trap

What did researchers find about fish with mouth injuries?

• They had no difficulty feeding

• They grew larger than uninjured fish

• They had difficulty sucking prey into their mouths

• They were able to feed more efficiently

What system is disrupted by mouth injuries in fish?

• The respiratory system

• The digestive system

• The suction feeding system

• The circulatory system
