Striped bass are opportunistic predators that consume a diverse diet including baitfish (menhaden, herring, sardines), crustaceans (crabs, shrimp), squid, eels, and various marine worms. Their feeding patterns change seasonally and by location, with juveniles eating zooplankton and small invertebrates while adults become increasingly piscivorous (fish-eating). Understanding their diet is crucial for successful fishing, as striped bass size and feeding behavior directly influence the best baits and techniques to use.
Whether you call them rockfish or stripers, these remarkable fish have earned their reputation as one of America's premier game fish. This comprehensive guide explores their complete dietary preferences, feeding behaviors, and how this knowledge can dramatically improve your fishing success.
Understanding Striped Bass: The Basics
Before diving into what striped bass eat, it's important to understand the characteristics of striped bass that make them such effective predators. These anadromous fish possess streamlined, silvery bodies marked with distinctive horizontal black stripes that extend from behind the gills to the base of their tail.
Rockfish vs striped bass is actually a regional naming convention rather than a species difference. North of New Jersey, anglers typically call them striped bass or "stripers," while south of New Jersey they're known as "rockfish" or simply "rocks." Both terms refer to the same species: Morone saxatilis.
Adult striped bass commonly range from 20-40 pounds, though trophy specimens can exceed 50 pounds. Their striped bass size directly influences their prey preferences, with larger fish capable of consuming much bigger meals than their smaller counterparts.
What Do Striped Bass Eat?
Primary Baitfish Species
Menhaden (Atlantic Bunker) Menhaden, also called bunker or pogies, represent the most important food source for striped bass along the Atlantic coast. These oily, nutrient-rich fish are packed with the fats and proteins that fuel striper growth. Adult bunker can reach 15 inches, providing substantial meals that help striped bass pack on weight quickly.
Peanut bunker (juvenile menhaden) create different feeding opportunities. Since they're only 2-4 inches long, striped bass must consume dozens to satisfy their hunger, leading to extended feeding frenzies that can last for hours.
Herring Species Both blueback herring and alewife form crucial components of the striped bass diet. These fish migrate up rivers to spawn, coinciding perfectly with striped bass movements. River herring provide high-energy meals during critical pre-spawn and post-spawn periods when stripers need to rebuild their energy reserves.
Sardines and Anchovies In coastal waters, sardines and anchovies offer abundant forage. Their schooling behavior makes them easy targets for coordinated striped bass feeding attacks. These smaller baitfish are particularly important for juvenile and sub-adult stripers.
Crustaceans and Invertebrates
Crabs Blue crabs, green crabs, and lady crabs all fall prey to hungry striped bass. The crabs' hard shells provide calcium and other minerals, while their meat offers protein and fat. Striped bass often hunt crabs in shallow water during high tides when crabs are most active.
Shrimp and Mysid Shrimp Grass shrimp and mysid shrimp serve as important forage, especially in estuarine environments. These invertebrates are particularly crucial for juvenile striped bass transitioning from zooplankton to larger prey items.
Marine Worms Sandworms, bloodworms, and ragworms provide year-round food sources. These invertebrates burrow in sandy and muddy bottoms where striped bass actively hunt. Worms are especially important during winter months when other prey may be less available.
Other Important Prey Species
Squid Longfin inshore squid become primary forage during their seasonal migrations. Cape Cod waters particularly see intense squid feeding, with striped bass using their burst-speed capabilities to ambush squid schools. Dead squid also proves highly effective as bait.
American Eels Both juvenile and adult eels provide high-fat meals for striped bass. Eels are particularly abundant in brackish waters where many striped bass spend significant time. However, with declining eel populations, this food source has become less reliable.
Sand Lance (Sand Eels) These slender, elongated fish bury themselves in sandy bottoms, but striped bass have learned to dig them out. Sand lance feeding often occurs at or near the surface, creating excellent topwater fishing opportunities.
Life Stage Dietary Changes
Juvenile Feeding (First 2 Years)
What does striped bass eat changes dramatically as they grow. Newly hatched striped bass larvae feed on their yolk sacs for the first few days, then transition to microscopic zooplankton including copepods, rotifers, and other tiny organisms.
As juveniles reach 1-3 inches, their diet expands to include:
- Small mysid shrimp
- Insect larvae
- Tiny crustaceans
- Small worms
- Larval fish
Sub-Adult Transition (2-4 Years)
Sub-adult striped bass undergo a crucial dietary shift, becoming increasingly piscivorous (fish-eating). Their menu now includes:
- Small baitfish (2-4 inches)
- Juvenile crabs
- Larger shrimp
- Marine worms
- Small squid
Adult Feeding Patterns (4+ Years)
Mature striped bass become apex predators with diverse diets. Male vs female striped bass feeding patterns show some differences, with larger females capable of consuming bigger prey items due to their increased size and jaw capacity.
Seasonal Feeding Patterns
Spring Feeding (March-May)
Spring marks the pre-spawn feeding period when striped bass spawn in April through June, depending on location and water temperature. During this time, striped bass aggressively feed to build energy reserves for the spawning process.
Key prey during spring includes:
- River herring (alewife and blueback herring)
- Early-season squid
- Overwintered crabs
- Marine worms
When do striped bass spawn? Peak spawning occurs when water temperatures reach 60-65°F, typically mid-April through mid-May in the Mid-Atlantic region. The timing varies by latitude, with southern populations spawning earlier.
Summer Feeding (June-August)
Summer brings peak feeding activity as striped bass recover from spawning and take advantage of abundant forage. However, water temperature becomes critical—striped bass seek cooler water when surface temperatures exceed 75°F.
Summer diet highlights:
- Menhaden (both adult and peanut bunker)
- Sand lance
- Mackerel
- Squid
- Blue crabs
Fall Migration Feeding (September-November)
Fall represents prime feeding time as striped bass prepare for winter migration. This season often produces the year's best fishing as fish feed aggressively before heading south.
Fall forage preferences:
- Massive menhaden schools
- Late-season squid
- Migrating baitfish
- Crabs preparing for winter
Winter Feeding (December-February)
Winter feeding slows significantly as striped bass enter deeper, more stable water temperatures. Their metabolism decreases, reducing feeding frequency but not eliminating it entirely.
Limited winter diet includes:
- Deep-water baitfish
- Bottom-dwelling invertebrates
- Opportunistic feeding on available prey
Regional Diet Variations
Chesapeake Bay Diet
The Chesapeake Bay, producing 70-90% of Atlantic coast striped bass, offers incredibly rich feeding opportunities. The bay's diverse habitats support varied prey species:
- Shallow Flats: Blue crabs, grass shrimp, small baitfish
- Channel Edges: Menhaden, spot, croaker
- Tributary Mouths: River herring, white perch, catfish
- Deep Waters: Large menhaden, spot, bottom invertebrates
New England Coastal Waters
Cold, nutrient-rich New England waters support different prey assemblages:
- Sand lance (primary forage)
- Mackerel schools
- Squid (seasonal abundance)
- River herring (spring runs)
- Sea worms
Mid-Atlantic Surf Zone
The dynamic surf environment creates unique feeding opportunities:
- Surf clams and mussels (dislodged by waves)
- Sand fleas and beach crabs
- Mullet and other surf-adapted baitfish
- Spearing (Atlantic silverside)
Freshwater vs. Saltwater Diet Differences
Landlocked striped bass in freshwater environments must adapt their diets to available forage species. While their feeding instincts remain the same, the prey species differ significantly:
Freshwater Striped Bass Diet
- Primary Forage: Gizzard shad, threadfin shad
- Secondary Species: White bass, yellow perch, bluegill
- Seasonal Options: Alewife (where present), cisco, rainbow smelt
- Invertebrates: Crayfish, aquatic insects, freshwater shrimp
This dietary adaptation showcases the species' remarkable flexibility. Whether you're targeting striped bass in saltwater fishing locations or freshwater venues, understanding their opportunistic feeding nature remains crucial.
How Diet Knowledge Improves Your Fishing Success
Bait Selection Strategy
Understanding what striped bass eat directly translates to better bait choices:
Live Baits:
- Bunker (menhaden) - deadly during fall runs
- Herring - excellent for spring fishing
- Eels - productive year-round, especially at night
- Spot and croaker - versatile Chesapeake Bay baits
- Shrimp - effective for smaller stripers
Cut Baits:
- Fresh bunker chunks - release oils that attract fish
- Herring strips - perfect for surf fishing
- Squid strips - durable and scent-holding
- Clam bellies - excellent surf bait
Lure Selection Based on Prey
Topwater Lures: When striped bass feed on surface schools of baitfish, topwater lures excel:
- Poppers (mimic fleeing baitfish)
- Walk-the-dog style lures (injured baitfish)
- Swimming plugs (healthy baitfish)
Subsurface Lures:
- Bucktail jigs tipped with soft plastic (bottom feeders)
- Swimming plugs (schooling baitfish)
- Spoons (fleeing baitfish)
- Soft plastic shads (wounded baitfish)
Understanding different types of fishing techniques helps you match your approach to striped bass feeding patterns.
Feeding Behavior and Timing
Daily Feeding Patterns
Striped bass feeding follows predictable daily rhythms:
Dawn (5:00-8:00 AM): Prime feeding time as low light conditions favor ambush predation. Surface activity is common as baitfish schools are pushed upward.
Midday (11:00 AM-2:00 PM): Reduced surface activity, fish move deeper. Focus on structure and current breaks where baitfish concentrate.
Dusk (6:00-9:00 PM): Second prime feeding period. Surface activity resumes as baitfish become vulnerable in fading light.
Night (9:00 PM-5:00 AM): Continued feeding but more dispersed. Large stripers often feed actively at night when smaller fish seek shelter.
Tidal Influence on Feeding
Tidal movement dramatically affects striped bass feeding patterns:
Moving Water: Current brings fresh baitfish and oxygen. Focus fishing efforts during incoming and outgoing tides rather than slack periods.
Structure Interaction: Current hitting points, rocks, and pilings concentrates baitfish, creating feeding opportunities.
Depth Changes: Rising tides allow stripers to access shallow feeding areas previously unavailable.
Striped Bass Taste and Eating Quality
Many anglers wonder, "Does striped bass taste good?" The answer is a resounding yes, but with important considerations about size and preparation.
Optimal Eating Size The best-tasting striped bass typically measure 18-28 inches. Fish in this size range offer:
- Firm, flaky white meat
- Mild, slightly sweet flavor
- Minimal contaminant accumulation
- Manageable fillet size for families
Striped bass legal size varies by state and region, but many areas have slot limits protecting both small fish and large breeders. Always check current regulations before keeping fish.
Preparation Tips
- Remove the red "blood line" along the lateral line for milder flavor
- Keep fish iced immediately after capture
- Fillet soon after catching for best quality
- Remove skin to eliminate any "muddy" taste
Health Considerations Larger, older striped bass may contain higher levels of PCBs and mercury. Health advisories recommend limiting consumption to one serving per week and avoiding fish over 35 inches.

Expert Feeding Tips for Anglers
Reading Water for Feeding Activity
Surface Signs:
- Diving birds indicate active baitfish schools
- Surface splashes show feeding activity
- Oil slicks reveal recent feeding areas
- Nervous water suggests baitfish presence
Electronics Tips:
- Look for baitfish arches on fish finders
- Fish near the bottom in deeper water
- Target current breaks and structure edges
- Watch for temperature breaks where baitfish concentrate
Seasonal Fishing Strategies
Spring Strategy: Focus on river mouths and tributaries where striped bass intercept spawning river herring. Live eels and fresh herring work best.
Summer Strategy: Fish deeper water during midday, shallow areas during low-light periods. Target structure where baitfish seek shelter from currents.
Fall Strategy: Follow the baitfish schools. When you locate massive bunker or herring schools, striped bass won't be far behind.
Winter Strategy: Slow down presentations and fish deeper, more stable water temperatures. Focus on areas with consistent forage like oyster bars and mussel beds.
Advanced Feeding Pattern Recognition
Blitz Feeding: When striped bass drive baitfish to the surface in coordinated attacks, any topwater lure can be effective. Work fast as these feeding frenzies can end quickly.
Subtle Feeding: When fish feed selectively on specific prey, match the hatch precisely. Use lures that mimic the exact size, color, and action of natural forage.
Nighttime Feeding: Large stripers often feed at night when smaller prey fish are most vulnerable. Slow-swimming lures and live bait produce best results.
