Fisheries managers in Kansas face increasing challenges to diversify angling opportunities and increase appeal to a broader audience. One method of diversification is the development of alternative fisheries to complement those that are already established. To address this desire for diversification, age‐1 Channel Catfish Ictalurus punctatus and age‐0 Channel Catfish × Blue Catfish I. furcatus hybrids were stocked in equal numbers at approximately equal sizes in two Kansas impoundments to compare growth, body weight, and return to creel in public put–grow–take systems. Catfish were sampled over a 3‐year period with a suite of gears, including gill nets, baited tandem hoop nets, and low‐frequency electrofishing. Additionally, creel surveys were conducted at both impoundments in 2015 and 2016 to estimate angling success. Hybrid catfish exhibited more rapid growth than Channel Catfish and reached the 381‐mm minimum harvest length approximately 267–343 d earlier in both impoundments. Channel Catfish weight was 1.01–1.06 times the hybrid catfish weight at 280 mm, 0.96–0.99 times the hybrid weight at 410 mm, and 0.88–0.95 times the hybrid weight at 610 mm. Angler success did not differ between types of catfish in either impoundment during either year, but low sample sizes prohibited thorough comparison. More Channel Catfish (N  = 623) than hybrid catfish (N  = 297) were encountered with sampling gears, but differences in catch rate by gear were minimal, with no discernable patterns. Results presented herein provide evidence that hybrid catfish might be suitable for public put–grow–take fisheries. Additionally, growth and production benefits of hybrid catfish may make them a more economical option than Channel Catfish in these types of fisheries.

堪萨斯州两种公共放养捕捞渔业中Cat鱼和Channel鱼×蓝色Cat鱼杂种的生长，体重及其对游乐Cre的贡献比较

堪萨斯州的渔业经理们面临着越来越多的挑战，需要使垂钓机会多样化并增加对更广泛受众的吸引力。一种多样化的方法是发展替代渔业，以补充已经建立的渔业。为了满足这种多样化的需求，我们使用了1岁的Channel鱼Ictalurus punctatus和0岁的Channel鱼×蓝色Cat鱼I. furcatus在堪萨斯州的两个蓄水池中，以相同数量的大致相同大小的杂种动物被放养，以比较公共认养系统中的生长，体重和返回筒架。a鱼在3年内使用一套渔具进行了采样，包括刺网，诱饵串联环网和低频电鱼。此外，在2015年和2016年对这两个水库进行了纱架调查，以估算钓鱼成功。杂交cat鱼的生长速度比海峡fish鱼快，在两个水库中都达到了381-mm的最小收获长度，大约提前267-343 d。鱼的体重是280毫米杂交cat鱼重量的1.01-1.06倍，410毫米是杂交重量的0.96-0.99倍，610毫米时是0.88-0.95倍。在任何一年的任何一次蓄水中，鱼的成功率在不同类型的between鱼之间都没有差异，但是样本量少，无法进行全面比较。更多Channel鱼（N  = 623）比使用cat鱼 渔具的杂交cat鱼（N = 297）好，但渔具的捕获率差异很小，没有可辨别的模式。本文提供的结果提供了证据，表明杂交cat鱼可能适合于公共放养/捕捞渔业。此外，在这些类型的渔业中，杂交cat鱼的生长和生产效益可能使其比海峡Cat鱼更经济。
