Which fish species is specifically limited to a maximum length of 25 inches?

The correct choice highlights that both landlocked salmon and brown trout are species that have specific regulations limiting their maximum length to 25 inches. In many fishing regulations, particularly in Maine, certain species are managed to maintain populations and ensure sustainable fishing practices. For landlocked salmon, regulations typically aim to prevent overfishing of larger individuals that contribute to the reproductive stock. Similarly, the regulation for brown trout often aims to balance both the characteristics of the ecosystem and fishing enjoyment.

Since both species share this length limit, it's important for anglers to be aware of such regulations to promote conservation efforts and maintain healthy fish populations. Understanding these specifics helps in responsible angling and adherence to state guidelines, positively impacting the future of fishing in the region.
