Maine Fishing Seasons And Regulations Guide In 2025

Welcome to Maine fishing! Whether you’re trying to fish here for the first time or you’re a seasoned angler, Maine’s lakes, rivers, and streams provide great opportunities for everyone. It offers some of the most diverse and pristine freshwater fishing experiences in the country.

This guide breaks down everything you need to know about fishing seasons, limits, gear restrictions, and licenses you need to know to make the most of your time on the water. Let’s get started!

Maine’s Fishing Seasons And Limits

Maine splits its inland waters into two zones: North and South. These zones have different season dates and rules, so always check which zone you’re in before planning your trip. Here’s a breakdown of the fishing seasons for inland waters:

North Zone Fishing Season

Lakes & Ponds: Open April 1 – September 30 for open water fishing. Closed October 1 – March 31.

Rivers, Streams & Brooks:

• April 1 – August 15: Open to all methods.
• August 16 – September 30: Artificial lures or flies only.
• Closed from October 1 – March 31.

Tip: The North Zone is prime for wild brook trout and Arctic charr. Be ready to pack your fly rod for late-summer river fishing.

South Zone Fishing Season

Lakes & Ponds: Open year-round for ice and open water fishing.

Rivers, Streams & Brooks:

• Open from April 1 – September 30.
• Closed from October 1 – March 31.

The South’s milder climate allows for longer lake fishing, while the North’s colder winters protect spawning fish in rivers.

Species-Specific Possession And Size Limits

Maine is home to a variety of fish species, each with specific bag limits and minimum length requirements. You need to know which types of fish you can or cannot catch. Familiarizing yourself with these will help you stay compliant with state regulations.

Following are the total possession limits and size limits of each fish for inland water fishing:

Some of the waters have special regulations and season dates that differ from the general fishing laws. You can check those specific zones here: Maine Fishing Lawbook.

Interstate Waters Fishing Season (Maine&New Hampshire)

Fishing seasons in these areas vary throughout the year, depending on the type of fishing and the location.

Ice fishing is allowed from January 1 to March 31 on lakes and ponds, and you can catch all species except landlocked salmon and cusk. For open water fishing, lakes, ponds, rivers, streams, and brooks are open from April 1 to September 30, and you can fish for all species.

From October 1 to December 31, lakes and ponds remain open for all species, but if you catch trout, landlocked salmon, or togue, you can only catch and release them immediately.

During this same period, rivers, streams, and brooks are closed to all fishing, except for the Salmon Falls River.

Winter tip: South Zone lakes stay open year-round—perfect for enthusiastic anglers!

Now that you’re familiar with the fishing season schedules for interstate waters, here’s the information on the total numbers and minimum size for each fish species you can catch:

Free Fishing Days

One of the great opportunities Maine offers is Free Fishing Days. It’s a perfect chance for families and newcomers to experience Maine’s fishing culture without the initial investment of a license.

In 2025, these days will start on February 15-16 and May 31-June 1.

• February 15–16 (ice fishing)
