Spawn timing & temperature guide
The Striped Bass (Coastal) spawn cycle is driven by water temperature, not calendar date — fish initiate spawn behavior when water reaches 55°F regardless of when that happens in your region. Pre-spawn striped bass migrate from coastal Atlantic into tributary rivers (Chesapeake, Delaware, Hudson) as water temperatures climb throug
Spawn temperature gauge
Spawn behavior is driven by water temperature, not calendar date. The same striped bass (coastal) may spawn weeks earlier in southern range than northern — track water temp, not the date.
Spawn cycle
Phase-by-phase
Pre-spawn striped bass migrate from coastal Atlantic into tributary rivers (Chesapeake, Delaware, Hudson) as water temperatures climb through low 50s.
The Chesapeake spring trophy striper season targets pre-spawn bull stripers staging at the Bay mouth — VA trophy season runs through May.
Active spawning behavior. Broadcast spawners — eggs require flowing brackish water to remain suspended. Chesapeake Bay, Delaware Bay, and Hudson River produce the bulk of Atlantic Coast striped bass.

Conservation context
Atlantic striped bass populations are under ASMFC rebuilding plan due to overfishing and reduced recruitment. Slot limits are tight, harvest is restricted, and most coastal states have implemented additional spawn-period protections. C&R for trophy bull stripers (40+ inches) is widely practiced.
Post-spawn coastal stripers leave tributary rivers and migrate north along the Atlantic coast through spring and summer.
The post-spawn striped bass migration is the iconic East Coast inshore event — fish push north from Chesapeake toward Maine.
Fish disperse to summer habitat and feeding patterns. Spawn cycle complete until following year.
Standard summer fishing tactics apply.
Regional spawn windows
Striped Bass (Coastal) spawn timing varies by region. Southern range fish initiate spawn first; northern fish later.
Delaware Bay striped bass spawn peaks May.
Upper Chesapeake (Susquehanna Flats) is the largest single Atlantic striper spawning population — peaks late April to early May.
Lower Chesapeake (Rappahannock, James) spawn peaks April–May.
Spawn habitat
Typical depth: 5–30 ft
Male vs. female behavior
Broadcast spawners — eggs require flowing brackish water to remain suspended. Chesapeake Bay, Delaware Bay, and Hudson River produce the bulk of Atlantic Coast striped bass.
