Atlantic sturgeon abundance and movement in the lower Delaware River

Objectives: 1) Monitor abundance, length frequency, and population size of juvenile Atlantic sturgeon in the lower Delaware River. Use small mesh gill nets to establish the abundance of small, pre-migratory sturgeon. 2) Identify important habitats through sonic tracking. 3) Collect tissue samples for DNA analysis and spine samples for age and growth. 4) Develop an age / length key and apply it to previous catches to determine age composition. Project: AFC - 9 Final Report Time period covered: June 1, 1998 through May 31, 1999 Grant no. NA86FA0315
