__________ 2013 Year Class Report 4-1 CHAPTER 4 SPATIOTEMPORAL DISTRIBUTION OF SELECTED SPECIES OF HUDSON RIVER ESTUARY FISHES This chapter presents graphs of the spatiotemporal distribution within the Hudson River for 16 selected species as well as graphs of the temporal, geographical, and annual abundance indices for these species. Length data for young-of-year fish of several species are plotted.

Supporting tables for these graphs are provided in Appendices C (Species Composition), D (Density and Standing Crop Estimates), E (Temporal and Geographical Distribution Indices), F (Annual Abundance Indices), and G (Length Frequency Distribution). 4.1 SPECIES COLLECTED Overall species composition for each year from 1974 to 2013 and species composition by survey for 2013 are tabulated.

__________ 2013 Year Class Report 4-1 CHAPTER 4 SPATIOTEMPORAL DISTRIBUTION OF SELECTED SPECIES OF HUDSON RIVER ESTUARY FISHES This chapter presents graphs of the spatiotemporal distribution within the Hudson River for 16 selected species as well as graphs of the temporal, geographical, and annual abundance indices for these species. Length data for young-of-year fish of several species are plotted.
