Striped bass
Seven or eight continuous dark stripes mark a silvery predator that uses tidal rivers as nurseries and the coast as a highway.

Striped bass, often called rockfish in Maryland, link fresh, brackish, and salt water. Chesapeake spawning takes place in tidal rivers in spring, and young fish grow in sheltered bay waters before some join the broader Atlantic migration. Seven or eight dark stripes along a silver flank make the adult distinctive, though a view through rippled water rarely reveals every marking.
The state fish is not a stationary “Chesapeake fish” in every life stage. Coastal migrants travel north in warmer seasons and south as conditions change, while resident and pre-migratory fish have different patterns. Maryland biologists survey juveniles and spawning adults to understand year-class success and stock health. Watch for surface-feeding activity from a public shore without assuming that every splash is a striper or that a visible fish is legal to catch.

Quick guide
- Read the stripes
- Look for dark continuous lines along a silvery side.
- Watch the water
- Scan public tidal shorelines without entering spawning habitat.
Understand a fish that moves between waters
- Compare habitat
- A young bay fish and an ocean migrant use different water.
- Notice feeding
- Surface commotion can indicate schooling prey but not a certain ID.
- Count cautiously
- Glare can hide stripes; use body shape and setting too.
- Check the rules
- Current DNR limits govern any fishing, not this field guide.
Good to know
Striped bass fishing rules can change within a season and by waterbody. The app describes the fish’s ecology, not a current open season or harvest permission.

- Two separated dorsal fins
- Forked tail
