北温带湖泊的鱼类种群调查通常在秋季或春季进行，此时很容易用传统渔业技术捕获个体。因为有些鱼准备产卵或产卵在这些季节，有一个关键的需要，以更好地了解这些调查的决定，是有关鱼类reproduction.MethodsWe的潜在影响测试是否春季标志，再捕获调查使用fyke网，然后电捕鱼影响男性小嘴鲈鱼Micropterus killieuin北方威斯康星州湖的生殖行为。在2001-2008年期间进行了Fyke网，电捕鱼和全湖巢浮潜调查，并多年跟踪Floy标记的男性，以测试是否在fyke网捕获或在电捕鱼调查中捕获影响跨年度巢址保真度和生殖时间。和返回的男性被抓获的电捕鱼调查筑巢~50米远，从他们的前一年的巢比两个男性，仅捕获在fyke网和男性，没有被捕获的方法。平均年间巢距离为200米，中位数年间巢距离为90米的男性，没有捕获的电捕鱼调查。Electrofishing和fyke网没有影响的时间reproduction.ConclusionSpring electrofishing调查小嘴鲈鱼有可能取代繁殖男性首选的筑巢栖息地。如果位移对适应性产生负面影响（即，年龄-0存活到成熟），春季电捕鱼调查不建议用于评估Smallmouth Bass种群。然而，春季人口调查往往发生在冰关闭后不久，在这些较冷的温度下进行的调查通常压力较小，不太可能导致死亡。未来的研究应该测试的健身影响减少巢网站保真度以下Smallmouth低音电捕鱼，同时考虑潜在的健身权衡，如果调查是在今年晚些时候move.Impact statementFish种群通常在春季进行调查，因为许多物种移动到海岸线产卵在这个时候。靠近海岸线使鱼更容易捕获，但我们不太了解电捕鱼调查如何影响繁殖。这项研究有助于解决这一差距，以便更好地管理小嘴鲈鱼种群。
ObjectiveFish population surveys in north‐temperate lakes are often conducted in the fall or spring when individuals are easy to capture with traditional fisheries techniques. Because some fishes are preparing to spawn or are spawning during these seasons, there is a critical need to better understand the potential influences of these surveys on decisions that are related to fish reproduction.MethodsWe tested whether spring mark–recapture surveys using fyke nets followed by electrofishing affect the reproductive behaviors of male Smallmouth BassMicropterus dolomieuin a northern Wisconsin lake. Fyke netting, electrofishing, and whole‐lake nest snorkeling surveys were conducted during 2001–2008, and Floy‐tagged males were tracked across years to test whether capture in the fyke nets only or capture in the electrofishing survey influenced interyear nest site fidelity and reproductive timing.ResultThe mark–recapture surveys were conducted preceding the spawning of Smallmouth Bass, and returning males that were caught in the electrofishing survey nested ~50 m farther from their prior year's nest than both males that were captured only in fyke nets and males that were captured by neither method. Average interyear nest distances were ~200 m, and median interyear nest distances were ~90 m for males that were not captured in the electrofishing survey. Electrofishing and fyke netting did not influence the timing of reproduction.ConclusionSpring electrofishing surveys for Smallmouth Bass have the potential to displace breeding males from preferred nesting habitats. If displacement negatively influences fitness (i.e., age‐0 survivorship to maturation), spring electrofishing surveys would not be recommended for assessing Smallmouth Bass populations. However, spring population surveys often occur soon after ice off, and surveys that are conducted at these colder temperatures are typically less stressful and less likely to result in mortality. Future research should test for fitness implications of reduced nest site fidelity following electrofishing in Smallmouth Bass while considering potential fitness trade‐offs if surveys are moved later in the year.Impact statementFish populations are often surveyed in the spring because many species move to the shoreline to spawn at this time. Being near the shoreline makes fish easier to catch, but we do not understand well how electrofishing surveys impact reproduction. This study helps address this gap to allow better management of Smallmouth Bass populations.
