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.
