Stocking and electrofishing occurrence and abundance data for northern pike Esox lucius L. in >3800 km of French rivers across 7 years were compared to assess the effect of recreational fisheries stocking programmes on wild pike populations. A positive relationship was found between the additive effect of stocking and the size of the stocked pike. However, the stocking programmes implemented in France by recreational fishery managers from 2008 to 2013 increased the probability of pike occurring in the river network, without increasing abundance in well-established pike populations, because pike stocked in their early-life stages were used in most of the stocking programmes.

法国大都市北梭鱼(Esox lucius)在大空间和时间尺度上的放养效率

对超过 7 年法国河流中超过 3800 公里的北梭鱼Esox lucius L. 的放养和电捕鱼发生率和丰度数据进行了比较,以评估休闲渔业放养计划对野生梭鱼种群的影响。发现放养的附加效应与放养的梭鱼的大小之间存在正相关关系。然而,2008 年至 2013 年由休闲渔业管理者在法国实施的放养计划增加了河网中出现梭子鱼的可能性,但并未增加成熟的梭子鱼种群的丰度,因为大多数使用处于早期生命阶段的梭子鱼。的放养计划。
