When to fish
Length of season
The Miramichi opens for salmon fishing on April 15. The Southwest Miramichi headwaters close on September 30, and the rest of the system closes on October 15.
On April 15 the Miramichi system is still heavily populated with salmon that have spent the winter in the river after spawning. These fish are called kelts. They bite aggressively as they attempt to recondition and put on weight lost in spawning. This is a historic and very popular Miramichi fishery. The river is high and cold, and the fishing is generally done with sinking lines from boats. Kelt fishing lasts until May 15.
Spring salmon fishing
Salmon begin entering the Miramichi in late May, with the NW branch being known for the earliest arrivals. Mid-May through mid-June is also the most likely time to catch large, sea-run brook trout.
The famous “grilse run” typically begins during the first week of July, with the peak of the summer run occurring from the last week in June until the end of July.
Beyond these general guidelines, good fishing can take place anytime during the season with the right conditions. Even though late July through mid-August is normally the slowest part of the summer - often with warm and low water - a good rain and some cool mornings can bring in new fish and turn on those that are holding in the pools.
Autumn and Fall Fishing
The Miramichi is well-known for its very prolific fall run. The run starts the second week in September, reaches its peak the last week in September, and fresh fish are still arriving when the season closes on October 15.
