Young‐of‐year (age‐0) largemouth bass Micropterus salmoides from the Little Beaver Creek embayment of B. Everett Jordan Lake, North Carolina, were individually tagged with magnetic binary‐coded wire tags in 1989 and 1990. Fish were recaptured during electrofishing and seine sampling in the year of tagging and the following year. In 1989, 529 age‐0 largemouth bass were tagged, of which 40 were recaptured. Of these, only 2 of 31 age‐0 and 2 of 9 yearling fish had moved out of their tagging coves. In 1990, 1,090 age‐0 largemouth bass were tagged, of which 47 were recaptured. Of 15 recaptured largemouth bass that had been tagged in coves, only 2 age‐0 fish had moved from their tagging coves. Of 32 recaptured largemouth bass that had been tagged outside coves, only 2 age‐0 and 1 yearling fish had moved into cove areas. No tagged age‐0 or yearling largemouth bass were recaptured outside the embayment. Because most fish seem to stay near their tagging site, localized supplemental stocking of fingerlings may benefit largemouth bass populations in basin, bay, or cove areas of large, complex reservoirs.
