Fluke and porgy fire up in Long Island Sound as stripers dodge sharks

What's biting

What's next

If the pattern holds, expect the bottom bite to keep carrying Connecticut trips through the week ahead. Black Hawk's scup limits and mixed sea bass and triggerfish catches, per The Fisherman — Connecticut, suggest good numbers holding on the Sound's reef and rock piles, and that kind of consistency typically keeps producing through late August before cooling water starts thinning it out. Fluke should keep trending up too, since J&B Tackle's note that the bite 'continues to improve' around Sarah's Ledge, Two Tree Channel, Black Point, and Hatchetts Reef points to fish still stacking on structure rather than scattering, typical for this point in summer.

Striped bass are the one to watch. Both Tartan II and J&B Tackle describe the open-water bass bite pausing as brown shark numbers build in the areas bass normally use. If that shark pressure holds through the coming days, expect stripers to keep favoring the skinnier, harder-to-patrol water AW Marina is already seeing produce fish: the river mouth, up past the bridge, and around Fort Trumbull Pier. Anglers chasing bass locally may do better working those structure-tight, current-driven spots on a moving tide rather than open beach or reef water this week.

Zooming out to the wider region, The Fisherman (Northeast)'s August 13 forecast described the 'fall run pregame' ramping up from Narragansett to Plymouth with striper blitzes and a growing bonito push around Cape Cod, a signal that the broader Northeast migration is starting to stir even while the immediate Sound bite stays more bottom-focused for now. Saltwater Edge's August outlook similarly flagged that 'fall run fishing is on our doorstep' with a few more southerly wind days working in anglers' favor. Neither report is Sound-specific, but both are worth watching: as water temperatures typically ease off their summer peak over the coming weeks, bait and predator activity in Long Island Sound tends to trend toward that fall pattern, with striped bass and bluefish activity usually picking up as baitfish push into coves and river mouths. Plan around early morning and evening tide swings for the best shot at moving fish, and keep a heavier leader on hand if bottom fishing near known holding areas, since several CT shops report steady shark interest right now.

Context

Mid-August in Long Island Sound typically means a transition period: the summer bottom fishery (scup, black sea bass, fluke) is in full swing while striped bass activity gets more variable, often pushed around by warm surface water, boat traffic, and bait movement. This week's reports fit that seasonal shape closely. Strong porgy numbers and an improving fluke bite, per Black Hawk and J&B Tackle, are right on schedule for late-summer Sound fishing.

What stands out this year is how consistently Connecticut shops are flagging shark pressure as a factor in the striper bite. Tartan II and J&B Tackle both independently point to elevated brown shark presence as a reason bass have gotten harder to find in their usual spots, and Black Hawk landed one boatside during a routine porgy trip. That is a stronger and more consistent shark signal than a typical August report cycle produces, though without a state-agency source confirming whether shark numbers are genuinely up versus just more frequently reported this week, it is best treated as anecdotal for now.

The broader Northeast intel from The Fisherman (Northeast) and Saltwater Edge suggests the region is still in pre-fall-run mode as of mid-August, with blitz activity concentrated further east along Rhode Island and Cape Cod beaches rather than in the Sound itself. That is typical timing, since Long Island Sound's fall run usually trails the outer-coast migration by a few weeks. No CT-specific water-temperature or fishery-status data was available this cycle, so this comparison leans on shop reports rather than official monitoring data.
