What Atlantic Herring Are and Where They Live

Atlantic herring are small, silvery fish that school in massive numbers along the eastern coast of North America, from the Gulf of St. Lawrence down to North Carolina. They rarely exceed 15 inches in length, though some populations grow to 17 or 18 inches. Their compressed bodies, dark blue-green backs, and silver sides make them easy to spot in shallow water, and they move predictably between deep offshore wintering grounds and shallow coastal bays where they feed and spawn.

Herring are most abundant in the Gulf of Maine, the Bay of Fundy, and around Cape Cod, where they concentrate in spring and fall. They prefer water temperatures between 45 and 55 degrees Fahrenheit and are most active during the cooler months. Summer heat pushes them into deeper water or northward, while winter cold drives them offshore. Understanding these seasonal movements is the first step to finding them consistently.

Key Takeaways

  • Atlantic herring are most abundant in the Gulf of Maine and Bay of Fundy from April through June and again in September through November.
  • They school in tight formations near the surface in shallow bays and estuaries, making them visible and catchable with small jigs, spoons, and live bait.
  • Regulations vary by state and province—some require a commercial license even for personal use, while others allow them under general saltwater permits.
  • Herring are excellent bait for striped bass, bluefish, and cod, and many anglers target them specifically to use fresh or frozen for larger species.
  • The best fishing occurs at dawn and dusk in areas with strong tidal flow, where herring concentrate to feed on plankton.

Seasons and Timing for Herring Runs

Atlantic herring follow two main seasonal patterns. The spring run occurs from April through June, when herring move from deep water into coastal bays and estuaries to feed. This is the most reliable time to find them in shallow water, and catches are often heaviest in May and early June. Water temperatures are rising, daylight is long, and herring are aggressive.

The fall run begins in August and peaks from September through November. Herring gather in the same bays and estuaries before moving offshore to spawn and winter. Fall fishing can be even better than spring because the water is still warm enough for active feeding, but herring are concentrated and hungry. By December, most herring have moved to deep offshore grounds and are no longer accessible to shore or small-boat anglers.

Winter herring fishing is possible only from larger boats working offshore grounds, typically 20 to 60 miles from shore. Most recreational anglers focus on spring and fall, when herring are within reach from docks, jetties, and small boats in bays and estuaries.

Regulations by State and Province

Herring regulations differ significantly across the Atlantic coast. In Massachusetts, herring are managed under a commercial license system, but recreational anglers may take them under a general saltwater permit or fishing license. Daily bag limits and possession limits vary by year depending on stock assessments. Check the Massachusetts Division of Marine Fisheries website before each season for current rules.

In Maine, herring are regulated by the Department of Marine Resources. Recreational harvest is allowed, but some rivers and estuaries have seasonal closures to protect spawning populations. A saltwater fishing license is required. New Hampshire and Rhode Island allow herring under general saltwater permits, though specific bays may have local restrictions.

In Canada, herring regulations are managed by Fisheries and Oceans Canada (DFO). The Bay of Fundy and Gulf of St. Lawrence have separate rules, and some areas require a commercial license even for personal use. Contact your provincial fisheries office or the DFO before fishing to confirm what is allowed in your specific location.

How to Catch Atlantic Herring

Herring are caught most reliably with small jigs and spoons in the 1/4- to 1/2-ounce range. Silver, white, and chartreuse colors work well. Cast or jig vertically in areas where herring are schooling—usually near the surface in shallow bays, around pilings and jetties, and in channels with strong tidal flow. Herring respond to a steady retrieve or a jigging motion that mimics small baitfish. A single herring jig on a light spinning rod is often all you need.

Live bait is also effective. Small silversides, sand eels, or even small herring themselves work well. Fish them under a bobber in shallow water, or cast and retrieve slowly near structure. Herring will strike aggressively when they are feeding, so you will feel the bite immediately.

Timing matters. Fish at dawn and dusk when herring are most active. Slack tide and the first hour of incoming tide are usually best. Avoid midday when herring move deeper and feeding slows. In fall, herring often feed throughout the day, but early morning and evening are still most productive.

Where to Fish for Herring on the Atlantic Coast

The Gulf of Maine is the most consistent herring fishery in the United States. Cape Cod Bay, Massachusetts Bay, and the waters around Portland, Maine hold large populations in spring and fall. Jetties, piers, and shallow estuaries are accessible to shore anglers. The Bay of Fundy in Nova Scotia and New Brunswick is equally productive and offers some of the largest herring populations on the continent.

Specific productive areas include the Merrimack River estuary in Massachusetts, the Kennebec River in Maine, and the Penobscot Bay area. In Rhode Island, Narragansett Bay and the waters around Block Island hold herring in spring and fall. New York's Hudson River estuary and Long Island Sound support smaller populations but are still worth fishing during peak seasons.

Access varies. Many productive areas are accessible from public docks, jetties, and boat launches. Some private marinas allow day-use access for a fee. Check local regulations and ask at tackle shops for current conditions and access points—herring populations shift within bays from year to year, and locals know where they are concentrated.

Using Herring as Bait for Larger Fish

Many anglers target herring specifically to use as bait for striped bass, bluefish, and Atlantic cod. Fresh herring are among the most effective baits for these species, especially in spring and fall when herring are abundant. A whole small herring (4 to 6 inches) fished on the bottom or under a bobber will attract larger predators quickly.

Frozen herring are also reliable and easier to store and transport than fresh bait. They work nearly as well as fresh herring and are available year-round at most tackle shops. Many anglers catch herring in May or June, freeze them, and use them throughout the summer and fall for bass and bluefish fishing.

If you plan to use herring as bait, check local regulations—some areas require that bait fish be caught in the same water where you intend to fish them, to prevent the spread of disease or invasive species. Ask at your local tackle shop or check your state's fisheries website for specific rules.

Gear and Tackle Setup

A light spinning rod (5 to 6 feet) with 6- to 10-pound test line is ideal for herring. Herring are not strong fighters, so you do not need heavy gear. A small spinning reel that holds 150 to 200 yards of line is sufficient. Pair it with a 2- to 4-pound fluorocarbon leader if you are using jigs or spoons.

For jigging, use a single small jig (1/4 to 1/2 ounce) on a short leader. For live bait, use a small circle hook (size 4 to 6) and a bobber to keep the bait at the depth where herring are feeding. A simple three-way rig with a sinker and a short leader to a baited hook also works well for bottom fishing in deeper channels.

Waders are useful if you plan to fish from shore in shallow bays and estuaries. A small net makes landing herring easier, especially when fishing from jetties or docks. Herring are slippery and can escape quickly if not handled carefully.

Frequently Asked Questions

What is the best time of day to fish for herring?

Dawn and dusk are most productive, when herring move into shallow water to feed. Slack tide and the first hour of incoming tide are also reliable. Midday fishing is slower, especially in spring, though fall herring may feed throughout the day.

Can I keep herring I catch and use them as bait?

Yes, in most states and provinces. Check your local regulations first—some areas require that bait fish be caught in the same water where you intend to fish them. Your state fisheries website or a local tackle shop can confirm the rules for your area.

Do I need a special license to fish for herring?

Requirements vary. Most states require a general saltwater fishing license. Some areas, particularly in Canada and parts of New England, may require a commercial license even for personal herring fishing. Contact your state or provincial fisheries department before you fish.

What size herring should I target?

Most herring range from 8 to 15 inches. Smaller herring (6 to 10 inches) are easier to catch on light jigs and make excellent bait for striped bass and bluefish. Larger herring (14 to 17 inches) are less common but are better for bait if you are targeting very large stripers or cod.

Where can I find herring in winter?

Winter herring move to deep offshore grounds, typically 20 to 60 miles from shore. They are accessible only to larger boats equipped for offshore fishing. Most recreational anglers fish for herring only in spring and fall when they are in shallow coastal bays.
