Abstract

White Crappie (Pomoxis annularis) and Black Crappie (P. nigromaculatus) were studied in three southeast Kansas reservoirs to assess exploitation and determine if current regulations were conducive for sustainable populations. Trap nets were used to sample crappie in Elk City Reservoir, Big Hill Reservoir, and Parsons City Lake. Crappie measuring 210 mm and greater received Floy FD-94 tags that served as entries for rewards to encourage tag reporting. Harvest and angler demographic information were collected when tags were reported. Postcard surveys and motion-sensed cameras were used in conjunction to estimate angler effort and reporting rate on Parsons City Lake. Annual exploitation rates (i.e., percent of fish harvested) determined by tag returns and corrected for nonreporting and tag loss were 28.3%, 21.8%, and 3.9% on Elk City Reservoir, Big Hill Reservoir, and Parsons City Lake, respectively. Overfishing was not occurring, so current statewide regulations were likely appropriate, and no changes may be necessary.

评估堪萨斯州东南部三个水库中白螃蟹和黑螃蟹的开发情况
对堪萨斯州东南部三个水库中的白螃蟹(Pomoxis annularis)和黑螃蟹(P. nigromaculatus)进行了研究,以评估开发情况并确定当前的法规是否有利于种群的可持续发展。使用诱捕网对麋鹿城水库、大山水库和帕森斯城湖中的螃蟹进行了取样。210毫米及以上的螃蟹会被贴上 Floy FD-94 标签,作为鼓励报告标签的奖励。在报告标签时,会收集收获量和垂钓者的人口信息。明信片调查和运动感应摄像机被用来估算垂钓者在帕森斯城湖的努力程度和报告率。麋鹿城水库、大山水库和帕森斯城湖的年开发率(即收获鱼的百分比)由标签回报确定,并对未报告和标签丢失进行了校正,分别为 28.3%、21.8% 和 3.9%。没有出现过度捕捞的情况,因此目前全州范围内的规定可能是适当的,可能没有必要进行修改。
