Geographic Distribution
Found in the North Atlantic Ocean on both American and European coasts. They range from North Carolina to Labrador on the western side and from Norway to Spain on the eastern side.
Seasonal Patterns
Mackerel migrate northward in spring and southward in fall, following temperature preferences. They spawn in open water during late spring and early summer in offshore areas.
Behavior & Diet
Feeding Habits
Mackerel are voracious predators that feed on small fish, squid, and zooplankton. They hunt in large schools and are known for their feeding frenzies when prey is abundant.
Activity Patterns
Most active during daylight hours, often feeding near the surface. Mackerel form large schools and are constantly on the move, following prey and favorable water conditions.
Fishing Tips & Techniques
Effective Techniques
Effective techniques include trolling with small lures, jigging with diamond jigs, and casting small spoons or flies. Fish during tide changes and look for diving birds indicating feeding activity.
Recommended Gear
Light to medium action rods, spinning reels, and 10-20 lb test line. Use small, flashy lures in silver, blue, or green. Popular lures include small spoons, jigs, and multi-hook rigs.
Conservation Status
Mackerel populations fluctuate naturally and are managed through quotas and seasonal closures. They're an important forage species for larger predators and seabirds.
