摘要确定休闲渔业中小头黑鲈鱼自愿捕捞和释放的发生率，对选择和评估捕捞法规具有重要意义。在美国南部的一些渔场中，黑鲈鱼的自愿放生率有所增加，但放生率可能在空间上有所不同。1984年至2006年期间，我们对明尼苏达州167个水体进行了245次开放水域鱼网调查，对垂钓者进行了访谈，以确定在以黑鲈鱼为目标的垂钓者和不以黑鲈鱼为目标的垂钓者之间、在州内不同地理区域和不同时间段内，黑鲈鱼的释放率是否存在差异。在四个时间段中，以黑鲈鱼为目标的垂钓者和不以黑鲈鱼为目标的垂钓者之间的释放率排名值没有显著差异。1990年以前，该州北部和南部地区的黑鲈鱼释放率中值相似，任何一个地区都不超过80%。1990-1994年和1995-1999年期间，释放率中位数…
Abstract Determining the prevalence of voluntary catch and release occurring in recreational fisheries for black bass Micropterus spp. is important in selecting and evaluating harvest regulations. Voluntary release rates of black bass have increased in some southern U.S. fisheries, but release rates could vary spatially. We used angler interviews from 245 open-water creel surveys conducted on 167 Minnesota bodies of water during 1984–2006 to determine whether black bass release rates differed among anglers specifically targeting black bass and anglers that were not targeting black bass, among geographic regions within the state, and among time periods. Ranked values of release rate did not significantly differ between anglers targeting black bass and anglers not targeting them for any of the four time periods. Before 1990, median black bass release rates were similar in northern and southern regions of the state and did not exceed 80% in either region. During 1990–1994 and 1995–1999, median release rates ...
