Pelagic broadcast-spawning fishes (pelagophils) are considered susceptible to flow alteration because eggs and larvae drift passively in suspension for several days until they become free swimming (Battle and Sprules 1960; Balon 1975; Platania and Altenbach 1998). This project would develop statistical models that describe the relationship between pelagophils (e.g., Arkansas River Shiner) and flow elements. The data were previously compiled by a SARP project. In conjunction, status surveys will be reviewed and follow up surveys would be completed in areas where data were lacking.
Flow-ecology models across the region could be used to develop possible flow standards for Great Plains rivers. At a minimum, these efforts would benefit a recovery plan. These data would also be useful to better understand the likely implications of reduced flows on pelagic broadcast spawning fishes
