摘要: AbstractElevated water temperature has been shown to influence mortality during fishing tournaments. However, data on conditions in live wells are lacking, and the benefits of managing live-well equivocal. The objective current study was define a well live-release black bass Micropterus spp. angling tournaments, compare temperatures with ambient surrounding lake. For this, thermal loggers were added three different tournaments (17 across tournaments), anglers fished tournament using automatic recirculating pumps (recirculation aeration occurs freshwater is pumped in). Live found be significantly cooler (˜1°C) than epilimnion for two examined, 1°C warmer other examined. Based these findings, fish held do not ap...
