We examined the reproductive life history of calico surfperch (Amphistichus koelzi), including mating season, pregnancy, gestation, and multiple paternity utilizing Restriction site Associated DNA Sequencing (RADseq). Further, we compared the mating season of calico with barred (Amphistichus argenteus), walleye (Hyperprosopon argenteum), and silver (Hyperprosopon ellipticum) surfperches to determine if the timing of reproduction is divergent within and between the genera. In calico surfperch, mating season occurs from October to November, and females gestate from December to May. All broods exhibit multiple paternity with a range of four to seven sires per brood. The mating season of calico overlaps completely with barred surfperch; however, barred surfperches have a protracted mating season which extends until the beginning of December, which may be due to differences in reproductive strategy such as size at first reproduction. In the genus, Hyperprosopon mating season begins earlier than Amphistichus, with divergence in the onset of mating between Hyperprosopon congeners by approximately one month.

在冲浪区：对比背景下的印花布冲浪鲈（Amphistichus koelzi）的繁殖策略

我们利用限制性位点相关 DNA 测序 (RADseq) 检查了印花布 (Amphistichus koelzi) 的生殖生活史，包括交配季节、怀孕、妊娠和多亲关系。此外，我们将印花布的交配季节与禁止 (Amphistichus argenteus)、角膜白斑 (Hyperprosopon argenteum) 和银 (Hyperprosopon ellipticum) 海鲈进行了比较，以确定繁殖时间在属内和属之间是否存在差异。在 calico surfperch 中，交配季节发生在 10 月至 11 月，雌性在 12 月至 5 月怀孕。所有的后代都表现出多重父系关系，每只后代有 4 到 7 个公牛。印花布的交配季节与条纹鲈完全重叠；然而，被禁止的冲浪者有一个漫长的交配季节，一直持续到 12 月初，这可能是由于繁殖策略的差异，例如第一次繁殖时的大小。在该属中，Hyperprosopon 交配季节开始于 Amphistichus 之前，Hyperprosopon 同系物之间的交配开始时间相差大约一个月。本文受版权保护。版权所有。
