Looking for Advice: How to Catch Extremely Passive European Perch at This Spot?

Hey everyone,

Looking for some advice on how you’d approach this spot this time of year, because I’m kind of running out of ideas.

Spot details: Small bay, roughly 390 x 425 feet (about 120 x 130 m). Saltwater, water temperature around 39°F (4°C). Estimated depth 5–10 feet (1.5–3 m). Water is very dirty / stained brown, low visibility. Heavy fishing pressure. Fish seem extremely inactive / lethargic.

How would you fish an area like this: The water is near-freezing. Visibility is poor. Fish are very pressured and lethargic. Would you: Go even slower (dead-sticking, long pauses)? Focus more on vibration or scent? Upsize profile for visibility or downsize even further? Stick tight to bottom structure, or experiment with mid-water presentations? Switch to something totally different (live bait, blade baits, suspending lures, etc.)?

Any cold-water salt/brackish-water tips, lure recommendations, or presentation tweaks would be hugely appreciated. Even small adjustments might make a difference in conditions like these.

What I’ve tried so far: Traditional jighead + soft plastics Dropshot Ned rig

Gear setup: Rod: Abu Garcia Veritas Sensi-S Light Reel: Daiwa Fuego 23 – 1000 Main line: 0.10 mm braid (≈ 8 lb test) Leader: 0.25 mm fluorocarbon leader (≈ 10 lb test)

I’ve slowed everything way down, downsized, and tried fishing painfully slow, but bites are either nonexistent or extremely subtle.

Thanks in advance folks!
