How can anglers harm the fish?

Anglers can harm fish through practices such as improper catch and release, where fish are handled roughly or kept out of water for too long, leading to stress or injury. The use of non-barbless hooks can cause significant damage to fish's mouths, and fishing gear can result in entanglement or ingestion, leading to injury or death. Additionally, pollution and habitat destruction from fishing activities can negatively impact fish populations and their ecosystems.
