3 Last Fall I was fishing for striped bass using green crabs and sand fleas for bait but without any luck. In this presentation I will look into the biology of striped bass in order to determine why I haven t been able to catch them in the past, and what I need to know to have the best chance of catching them this year Including their migration patterns, diet, and habitat use.

4 The striped bass population is currently abundant and sustainably fished. They can live up to 30 years and grow up to 6.6 feet long. Striped bass are anadromous fish that range all along the east coast of the USA. They spawn in several estuaries along the east coast with the Chesapeake bay being the largest.

5 Striped bass females are mostly migratory, so their habitat is very large. They can be found off the coast of South Carolina to as far North as Nova Scotia. Males on the other hand will stay around their natal estuary for their whole life. Within estuaries different contingents exist in which subpopulations will live in varying degrees of salinity. These contingents stay out of each other s way. Females in the same contingent will school together in migrations Return to same area to spawn every year.

6 Migration groups have highly varied destinations. Different contingents take different routes to get to the same general locations during migrations.

7 In the spring females migrate north to Massachussets stopping in the Chesapeake bay in late April to Mid-May (Now!) In the fall, females migrate south towards the Carolinas, stopping in the Chesapeake bay in Mid October to Early November.

8 Amphipods (small shrimp like crustaceans) are most common prey for smaller juveniles As they get bigger they eat more blue crabs and lots of bunker. Bunker makes up the majority of the dietary biomass in migratory striped bass, and it is suggested that striper migration may be patterned in part to follow the migration of bunker.

9 To have the best chance of finally catching a big striper I will be applying the following plan: First go fishing ASAP if at all possible! Second, This Fall I will check the fishing reports in New Jersey around early to mid October. Third check the local tackle shops for freshly caught wild bunker. Lastly use the fresh bunker for bait instead of green crabs and sand fleas.
