                  The project started in February by filling the pond,
                then fertilizing the pond in April so there would be plen-
                ty of zooplankton for the brood stock to eat.
                  After the pond was fertilized,  threadfin shad brood
                stock was collected from Tenkiller Lake.
                  The shad were hauled to the nursery pond to start
                spawning. Some of the fish just couldn’t wait, and shad

                had been placed in the pond. And in short order, the first                                          MATTHEW PALLETT/ODWC

                can actively feed for itself.
                  As  the  weeks  passed,  the  shad  grew  to  fingerling
