Bag limits are restrictions on the number and size of animals or fish that can be caught and kept by hunters or fishermen during a single trip or season. Synonyms for the term include harvest limits, catch quotas, and possession limits. These are regulations put in place to protect wildlife populations and ensure sustainable hunting and fishing practices. The purpose of bag limits is to prevent overfishing and overhunting, which can have a negative impact on the environment and the species that live within it. By enforcing bag limits, authorities are able to control the harvesting of wildlife and maintain a healthy balance in natural ecosystems.
