We evaluated 24‐h poststocking survival of fingerling black crappies Pomoxis nigromaculatus (mean total length 117 mm) that were cheek‐tagged with binary‐coded microwire (CW) tags and estimated the percent contribution of stocked fish to a naturally occurring year‐class in a Florida lake. Retention of CW tags at 15 d was high (96%), but posttagging survival of CW‐tagged fish was low compared with reports for other CW‐tagged species and for untagged fingerling black crappies. Survival at 24‐h averaged 26% (SD = 11) for CW‐tagged fish held in a cage in Lake Jeffords, Florida. Ten months after stocking 294 fingerling black crappies/ha in Lake Jeffords, only 4.8% of the age‐1 fish sampled from the lake with otter trawls had CW tags. Low posttagging survival probably contributed to the low percent contribution of stocked fish to the naturally occurring year‐class.
