Delaware Weakfish (sea trout / gray trout) 2026 — Season, Bag Limit, Size Rules

Cynoscion regalis

Last updated May 26, 2026

Weakfish — known locally as 'sea trout' or 'gray trout' or 'tide-runners' — was historically Delaware's marquee bay sport-fish, with the Bowers Beach + Slaughter Beach + Indian River Inlet spring run (May – June, when fish move into Delaware Bay to spawn) producing some of the most concentrated weakfish fishing on the entire US Atlantic coast. The species suffered a catastrophic ASMFC-coastwide stock collapse beginning in the mid-2000s (peak documented landings 1980, decline accelerating through the 1990s and 2000s, full collapse 2008), and DNREC + ASMFC now run a drastically reduced emergency rule that has remained in effect since 2009 as the stock slowly rebuilds — 13-inch minimum + 1 fish per angler per day (down from pre-collapse 8 / day at 13 in min in DE). The stock has shown modest signs of recovery in recent years but remains a fraction of pre-collapse biomass. Delaware Bay weakfish are still a viable spring fishery in the Bowers Beach to Slaughter Beach run May – June, plus occasional fall catches around the Indian River Inlet and the artificial reefs in Delaware Bay. Always confirm current-year DNREC Marine Fisheries notices — weakfish regs may be reset under ASMFC stock-rebuilding adjustments.
