We measured bluefish (Pomatomus saltatrix) weights, densities, and prey sizes during the summers of 1992 and 1993 and diets over a 4-year period (1990-1993) in the Hudson River estuary. This information was used to estimate the loss of young-of-the-year (YOY) striped bass (Morone saxatilis) resulting from YOY bluefish predation. We then compared this predation mortality with the total loss of striped bass in the system. Data from sampling surveys conducted since the mid-1970's were used to examine relationships between bluefish abundance and striped bass recruitment levels. YOY striped bass, bay anchovy (Anchoa mitchilli), Atlantic silverside (Menidia menidia), and Alosa spp. dominated YOY bluefish diets. There were ontogenetic and interannual differences in YOY bluefish diets. Bluefish avoided striped bass at low densities but selected for them at high densities, suggesting a density-dependent feeding response. In the early summer of 1993, bluefish predation accounted for 50-100% of the total estimated loss of YOY striped bass. A significant negative correlation exists between the relative magnitude of striped bass recruitment and bluefish abundance. We conclude that YOY bluefish are important predators of estuarine fish and can have a substantial impact on their recruitment.

<em>Abstract.</em>—Our objectives were to determine if striped bass <em>Morone saxatilis </em>larvae were present in the East River and if so, could they have come from the Hudson River. To meet the first objective, we examined entrainment data collected at the Charles Poletti Power Plant (Poletti) during the years 1999 through 2002. To meet the second objective, we examined the simulated release of 168,000 neutrally buoyant, passive particles in the lower Hudson River Estuary, using a particle-tracking model that was linked to an estuarine circulation model. We also compared the abundance of striped bass post-yolk-sac larvae (PYSL) collected in the East River at Poletti with the abundance of striped bass PYSL collected in the Battery region of the lower Hudson River Estuary and the abundance of striped bass PYSL in the Battery region with freshwater flow in the estuary. Striped bass PYSL were collected by entrainment sampling in the East River at Poletti every year from 1999 through 2002. The striped bass PYSL in the East River probably came from the Hudson River Estuary because the median probability that neutrally buoyant, passive particles would be transported from the lower Hudson River Estuary to the upper East River and western Long Island Sound was 0.12, with a median transport time of 2 d, and because the mean density of striped bass PYSL was highest at Poletti and in the Battery region during the same year. The abundance of striped bass PYSL in the Battery region was higher when freshwater flow during May and early June was higher.

Abundance Estimates

Annual abundances of eggs, yolk-sac larvae (YSL), post-yolk-sac larvae (PYSL), and young-of-the-year (YOY) stages of Morone americana and Morone saxatilis are summarized from a 17-yr monitoring program in the Hudson River Estuary. Variability in temperature and freshwater flow in the Hudson River explained little of the interannual variation of early life stages of either species. Year class strength as indicated by the abundance of early life stages does not appear to be strongly influenced by environmental conditions. YSL were positively related to the abundance of eggs, but these relationships were weak, reflecting the high uncertainty in egg abundance estimates. There were positive relationships between the abundances of YSL and PYSL for both species. Our analysis implies that interannual variability in mortality is less important in determining recruitment to PYSL than the abundance of the prior life stages. There was no relationship, however, between the abundance estimates of PYSL and YOY. Differential mortality among years during the larval stage may result in juvenile recruitment being independent of larval abundance. A second possibility is that YOY are poorly sampled so that the monitoring programs currently provide inadequate estimates of the abundance of YOY.
