Delaware shad and spawning stripers pushing past Trenton in strong spring run

What's Biting

What's Next

The shad and striper corridor on the Delaware looks set to remain productive for at least another week or two. Per JB Kasper (The Fisherman — NJ/DE Freshwater), the Lewis Shad Fishery has been turning in consistent hauls, and the run typically holds through mid-May before tapering as the spawn winds down. Morning tide windows on the tidal reaches near Trenton and Lambertville have been moving fish upriver — drift presentations with shad darts and small spoons in the quarter- to three-eighths-ounce range remain the go-to. The 35-inch striper near Lambertville signals fish are pressing higher than typical; anglers working large soft-plastic swimbaits or live bait near rocky ledges and bridge pilings in the non-tidal reach should find opportunities as the push continues.

For bass and panfish, Old School Outdoors (Ewing) is seeing good crappies in the river, and local lakes are giving up decent numbers of largemouth and crappie as well. Fairfield Fishing Tackle cautions that largemouth action is erratic while fish fluctuate on and off the beds — warming afternoon windows tend to be the most reliable timing, as shallow fish move up to feed before evening temperatures pull them back. On Pine Barrens streams, the 37.1 cfs reading at USGS gauge 01408000 represents gentle, stable baseflow — ideal for light-spinning or fly-rod presentations to resident chain pickerel and bass in the cedar-tinted corridors. Expect those fish to make a full post-spawn transition to open-water patterns as temperatures firm up through the back half of May.

Trout fishing in the Delaware and Raritan Canal has been productive since the last stocking, per Old School Outdoors. NJ Fish & Wildlife expanded stocking locations and added days to the spring season this year, meaning the canal corridor has more access points than in recent seasons. Early mornings before angling pressure builds remain the sharpest timing window for stocked fish.

The Last Quarter moon generally mutes tidal influence on river fish, which can open up broader feeding windows rather than the concentrated tidal-burst bites that a full or new moon drives. If winds stay manageable through the weekend, Saturday morning through mid-day shapes up as the top shad-and-striper window along the Delaware.

Context

Early May is traditionally the heart of the Delaware River American shad run in New Jersey, a migration that has defined the region's spring fishery for centuries. The Lewis Shad Fishery at Lambertville is one of the last operating commercial shad operations on the river, and JB Kasper's report of 30 to 65-plus fish per haul (The Fisherman — NJ/DE Freshwater) places this week squarely in the prime window. The run typically peaks between late April and mid-May, then fades quickly once the bulk of the fish have moved through or completed spawning — the next two weeks are the optimal time to target shad before that window closes.

The presence of a 35-inch striper in nets near Lambertville is notable. While some spawning stripers push into the lower tidal Delaware annually, strong upriver penetration into the non-tidal reach tends to track with robust coastal migration years. On The Water flagged this spring as one of the best striper seasons in recent memory along the NJ coast, and the upriver striper signal here is consistent with that broader picture.

For the Pine Barrens, USGS gauge 01408000 at 37.1 cfs is a normal, expected reading for early May. Pine Barrens streams are low-gradient and tea-colored year-round; flow in this range keeps them accessible without the scouring that heavy rain events cause. Nothing in today's data suggests any unusual hydrological stress on that system.

The on-and-off bass bed pattern Fairfield Fishing Tackle describes is entirely typical for New Jersey freshwater in early May. Overnight temperature dips and daytime swings routinely disrupt spawning-stage fish before warmth stabilizes later in the month. Anglers who have fished this region in prior years know that consistent all-day bass bites are rare before Memorial Day — afternoon windows and slow presentations near structure are what produce during this transition. No comparative data is available in this report to quantify whether conditions are running early or late relative to prior years, but the activity level across shad, stripers, crappie, and bass all points to a season tracking close to schedule.
