Grady, J. M. and G. A. Conover (1998). Mississippi River Basin paddlefish research coded-wire tagging project - 1997 Annual Report. Mississippi Interstate Cooperative Resource Association, MICRA Annual Report.
The Mississippi Interstate Cooperative Resource Association (MICRA) planned, organized, and initiated a long-term, multi-state, multi-jurisdictional paddlefish study to assess the status of paddlefish stocks throughout the Mississippi River Basin in 1994. Two previous Interim reports contained information regarding fish tagging efforts in 1995 (Oven and Fiss 1996) and tag reading and database construction (Bettoli and Brennan 1997). This report summarizes progress made through 1997. MICRA participants participated in 420 sampling trips in 1996 and 1997 resulting in about 10,400 hours of effort. Biologists captured, tagged, and released 2,455 wild paddlefish in 1996 and 2,244 fish in 1997. More hatchery reared paddlefish were released to date in 1997 (127,743) than in 1996 (113,306). The total number of hatchery paddlefish released by MICRA cooperators is 437,022. Through January 1997, 701 paddlefish released by MICRA cooperators have been recaptured. Dossiers on each recaptured paddlefish were completed and provided to MICRA cooperators. Care and maintenance of the paddlefish databases were transferred from Tennessee Technological University to the U.S. Fish and Wildlife Service in March 1998. Changes in datasheet protocols were made after consultation with MICRA cooperators and are presented in Appendix B.
