How many pickerel can be kept in a single day's catch?

The correct answer reflects the regulations governing the daily catch limit for pickerel in Maine. State fisheries management often establishes specific limits to ensure sustainable fishing practices and conservation of fish populations. In this case, a daily limit of 10 pickerel means that an angler can legally catch and keep up to this number in a single day. This regulation helps regulate the fishery by preventing overfishing and allowing populations to remain healthy and viable.

Other options may lack realistic conservation measures or may not adhere to current regulations, which typically set specific limits based on species to protect aquatic ecosystems. Understanding these limits is crucial for responsible fishing practices and contributing to the overall health of Maine's natural resources.
