Recruitment contributions and natal fidelity in tributary rivers of the Grand Lake, Oklahoma, Paddlefish stockNARA Subscribed
Microchemistry of sectioned dentary (lower jaw) bones was used to determine natal river (Neosho, Spring or Elk River) of paddlefish Polyodon spathula (Walbaum) in the economically important snag fishery in Grand Lake, northeastern Oklahoma, and to assess the relative importance of the tributary rivers as sources of recruits to the fishery. Geological differences between the Neosho River and Spring River watersheds resulted in...
Recruitment sources and spatial patterns of population demographics of spotted bass in a large river–tributary networkNARA Subscribed
Understanding spatial patterns in population characteristics and the principal natal environments supporting riverine fish populations are important for fisheries management. Fin ray microchemistry was used to identify natal environment, and age estimates from sectioned fin rays were used to estimate growth and mortality rates for spotted bass, Micropterus punctulatus (Rafinesque), in a segment of the Ohio River (Smithland Poo...
