Early Spring Fishing in Connecticut: What's Biting in March, April, and May
Connecticut fishing follows a predictable spring progression that rewards anglers who understand the timing. Ice-out in late February and early March activates the first species. The trout stocking program fires up in April. By May, bass are in pre-spawn, shad are running in the Connecticut River, and the first stripers are pushing into tidal rivers from the Sound. Knowing what to target and when makes the difference between a blank day and the best fishing of the year.
March: Ice-Out and Yellow Perch
Connecticut's late winter/early spring is yellow perch season. Perch move into the shallows of ponds and lakes to spawn as ice retreats, typically late February through late March depending on the winter's severity.
**Where:** Shallow coves and shorelines in most CT ponds and lakes. Gardner Lake, Mashapaug Lake, Lake Zoar, and Bantam Lake are reliable early-season perch spots.
**What works:** Tube jigs and small grubs in 1/16–1/8 oz on ultralight tackle. Live minnows under a bobber. Small Rapala shad raps. Perch are most active on sunny afternoons when shallow water warms fastest.
**Why it matters:** Yellow perch provide the first consistent action of the year and are excellent table fish. Limit bags apply — check DEEP regulations for current limits.
The window is March–early April; once temperatures climb and bass become more active, perch disperse from their spawning aggregations.
April: Trout Stocking Season Opens
Connecticut's DEEP stocks over 500,000 trout annually into over 100 rivers, streams, and ponds throughout the state. Most stockings begin in early to mid-April, with the season running through mid-May for most waters (some year-round stocked ponds receive additional stockings in fall).
Stocked fish are rainbow, brown, and brook trout in the 10–14 inch range, with some trophy-size fish mixed in at designated "trophy" stocking locations. They hold in the same pools and runs for several weeks after stocking before either being caught or dispersing.
**Timing your outing:** Fish within the first 7–10 days after stocking for the densest populations and most willing fish. DEEP publishes stocking reports on their website — check what was stocked and when before driving to a location.
**What works:** Inline spinners (Rooster Tail, Panther Martin), small Rapalas, PowerBait (specifically for recently stocked fish conditioned to hatchery pellets), and nightcrawlers. Recently stocked trout are far less selective than wild fish.
Trout/salmon stamp required in addition to a standard fishing license.
April–May: Pre-Spawn Bass
Largemouth bass become increasingly catchable as water temperatures climb through 50–60°F in April. Fish that were lethargic in cold water become actively feeding in preparation for the spawn (which typically occurs in late May–early June in Connecticut when water reaches 62–68°F).
**Pre-spawn bass behavior:** Fish move from winter deep-water staging areas into transitional structure — secondary points, the mouths of coves, north-facing banks that warm first, and shallow flats near spawning areas. They're aggressive and feeding heavily.
**What works:** Slow-rolling a spinnerbait around the edges of the first cover you find in 4–8 feet of water. Jigs worked slowly along bottom transitions. Shad-pattern crankbaits in the 35–55°F range. As temperatures climb past 58–60°F, topwater and shallower presentations become effective.
The pre-spawn window — roughly mid-April through mid-May in CT — often produces the biggest bass of the season. Fish are shallow, feeding aggressively, and before the angling pressure of summer builds.
May: Connecticut River Shad Run
The American shad run in the Connecticut River is one of the most underappreciated fishing events in New England. Shad are anadromous — they spend their adult lives at sea and return to rivers to spawn. The Connecticut River shad run produces fish in the 3–6 lb range in significant numbers from mid-April through late May.
**Where:** The entire tidal Connecticut River from Old Saybrook to Hartford holds shad during the run, with concentrations at the Enfield Dam (the first significant upstream barrier) and at the Salmon River confluence near East Haddam.
**What works:** Shad darts in chartreuse, red, or white — a specialized small metal lure that shad hit aggressively. Fish on a slow dead drift just above bottom, or use a tandem rig with two darts. Fly fishing with small flash streamers is equally effective. Shad don't eat in freshwater (they're running on stored energy), but will hit lures out of aggression.
**License note:** Shad are included in your standard CT fishing license — no additional stamp required.
Late May: First Striped Bass in Tidal Waters
Striped bass enter Connecticut's tidal rivers and harbors from Long Island Sound beginning in May, following the baitfish migration that precedes summer. The first fish to arrive are often among the largest of the year — cows (large female stripers) that have been wintering south of Cape Hatteras move north earliest.
**Where to start:** The Salmon River mouth at Salmon Cove (East Haddam), Niantic River, Mystic River, Thames River, and the Connecticut River below the Salmon Cove area. Rocky shores along the CT coastline at Harkness Memorial, Ocean Beach, and Hammonasset State Park all produce early-season fish.
**What works:** Live herring or alewives fished on a 3/0 circle hook and light sinker under a float or free-lined. Swimming lures (Bomber A-Salt, Yo-Zuri pencils), bucktail jigs, and large soft plastics (Hogy, Tsunami shads) at dawn and dusk.
May striper fishing often provides the cleanest action of the season before summer traffic, boat pressure, and warmer water push fish into different patterns. Early birds catch the best stripers.
