摘要目前对黑鱼的管理策略--特别是大口黑鱼和小口黑鱼--有时会在繁殖活动期间结合休渔季节的规定。我们的实地研究调查了垂钓者遵守安大略省关闭的黑鱼捕捞季节的情况，以及非法季前捕捞和放生钓鱼如何影响黑鱼的繁殖成功。研究区域由安大略省东南部两个湖泊和两条河流中2公里长的海岸线组成。实验程序包括对垂钓者活动的目测评估，对黑鱼繁殖成功的目测监测，以及对雄性黑鱼个体的实验垂钓。我们的结果表明，至少在休渔季节覆盖的一些水域，有大量的季节前垂钓来筑巢雄性黑鱼。结果还表明，这一非法活动在一些水域相当严重，足以减少鱼苗产量。问题是……
Abstract Current management strategies for black bass Micropterus spp.—specifically, largemouth bass M. salmoides and smallmouth bass M. dolomieu—sometimes incorporate regulations with closed fishing seasons during reproductive activities. Our field study investigated how well anglers were complying with Ontario's closed black bass fishing season, and how illegal preseason catch-and-release angling was affecting black bass reproductive success. Study areas were composed of 2-km stretches of shoreline in two lakes and two rivers in southeastern Ontario. Experimental procedures involved visual assessment of angler activities, visual monitoring of black bass reproductive success, and experimental angling of individual male black bass. Our results demonstrate that there is substantial preseason angling for nesting male black bass in at least some waters covered by the closed season. Results also indicate that this illegal activity is substantial enough in some waters to decrease fry production. The question t...
