Distribution, movements, and habitat use of small striped bass (Morone saxatilis) across multiple spatial scales
Distribution, movements, and habitat use of small (<46 cm,juveniles and individuals of unknown maturity) striped bass (Morone saxatilis) were investigated with multipletechniques and at multiple spatial scales (surveys and tag-recapture in the estuary and ocean, and telemetry in the estuary) over multiple years to determine the frequency and duration of use of non-natal estuaries. These unique comparisons suggest, at least in New Jersey, that smallerindividuals (<20 cm) may disperse from natal estuaries and arrive in non-natal estuaries early in life and take up residence for several years. During this period of estuarine residence, individuals spend all seasons primarily in the low salinity portions of the estuary. At larger sizes, they then leave these non-natal estuariesto begin coastal migrations with those individuals from nurseries in natal estuaries. These composite observationsof frequency and duration of habitat use indicate that non-natal estuaries may provide important habitat for a portion of the striped bass population.
