Catch regulations are rules set by wildlife management authorities to control the amount and types of fish or wildlife that can be harvested. These regulations help ensure sustainable populations, protect endangered species, and maintain healthy ecosystems. They often include limits on the size and number of fish or animals that can be caught, as well as specific seasons when fishing or hunting is allowed. These regulations can vary by location and may include specific guidelines for different species, such as trout or deer. Anglers and hunters must familiarize themselves with local laws to avoid penalties and contribute to conservation efforts.
