CHAPTER 1 INTRODUCTION Since 1973, an annual Year Class Report has been prepared on behalf of the several electric utility companies (collectively, the Utilities) operating generating stations in the Hudson River estuary. This report has been prepared on behalf of Dynegy Roseton L.L.C., Entergy Nuclear Indian Point 2 L.L.C., Entergy Nuclear Indian Point 3 L.L.C., and Mirant Bowline L.L.C.

Sponsorship and technical direction for the 1999 Hudson River Biological Monitoring Program, upon which this report is based, was provided by Consolidated Edison Company of New York, Inc.; New York Power Authority; Central Hudson Gas & Electric Corporation; and Southern Energy, New York. The principal reporting objective has been to present and analyze data on the distribution and abundance of early life stages of selected fish species based on field surveys conducted throughout the Hudson River estuary. The content and scope of these reports have varied over time from estimating the environmental impact of five Hudson River generating stations to focusing on indices of year class strength to describing the spatiotemporal distribution of selected fish species. Since the early 1990s, the annual Year Class Report has been standardized to describe the physical/chemical parameter patterns in the Hudson River estuary and the spatiotemporal distribution of 16 selected species of fish.

These 16 species were identified by the New York State Department of Environmental Conservation (NYSDEC) of interest for discharge permitting purposes.

This report adds to the historical database by describing the results of the Longitudinal River Ichthyoplankton Survey, the Fall Shoals Survey, and the Beach Seine Survey for 1999. The 1999 Year Class Report presents basic abundance and distribution data with the following objectives:

• Describe the patterns and variability of environmental parameters that may have affected fish distribution and abundance in the Hudson River estuary in 1999.

• Describe the distribution and abundance of 16 selected species of fish (Table 1-1) in the Hudson River estuary in 1999.

• Describe the fish community of the Hudson River estuary in 1999.

• Describe patterns in growth for the 1999 year class of key species.

• Summarize the results of the Atlantic tomcod food habit study for 1999 (presented in an appendix section).

This report is organized into four chapters with supporting appendixes. Data collection and analysis methods are described in Chapter 2. Physical and chemical parameters are described in Chapter 3 and fish community analysis and spatiotemporal distribution of selected fish species are presented in Chapter 4. Detailed data tables supporting report analyses are contained within the appendix sections as follows:

• Appendix A - Quality Control Report for the 1999 Hudson River Ichthyoplankton Laboratory Program and 1999 Fall Juvenile Survey;

• Appendix B - Physical/Chemical Parameters;

• Appendix C - Numbers of Fish Collected in the Long River (1988-1999), Fall Shoals (1985-1999), and Beach Seine (1985-1999) Surveys;

• Appendix D - Density and Standing Crop Estimates;

__________ 1-1 1999 Year Class Report

• Appendix E - Length Frequency Distribution;

• Appendix F - Atlantic Tomcod Food Habit Study; and

• Appendix G - Annual Abundance Indices.
