Abstract Tributaries provide spawning habitat for three of four major sub-stocks of Lake Erie walleye (Sander vitreus). Despite anthropogenic degradation and the extirpation of other potamodromous species, the Maumee River, Ohio, USA continues to support one of the largest fish migrations in the Laurentian Great Lakes. To determine if spawning habitat availability and quality could limit production of Maumee River walleye, two habitat suitability models were created for the lower 51 km of the Maumee River and the distribution and numbers of walleye eggs deposited in a 25 km stretch of river were assessed. Walleye eggs were collected using a diaphragm pump at 7 and 10 sites from March/April to May 2014 and 2015. The habitat suitability models showed that

确定莫米河角膜白斑鱼生产对伊利湖西部鱼类种群的栖息地限制:记录产卵地面屏障

摘要 支流为伊利湖角膜白斑鱼(Sander vitreus)的四个主要亚种群中的三个提供产卵栖息地。尽管人为退化和其他马蹄莲物种灭绝,美国俄亥俄州的莫米河继续支持劳伦森五大湖中最大的鱼类迁徙之一。为了确定产卵栖息地的可用性和质量是否会限制 Maumee River 角膜白斑的产量,为 Maumee 河下游 51 公里创建了两个栖息地适宜性模型,并评估了沉积在 25 公里河段中的角膜白斑卵的分布和数量。从 2014 年 3 月/4 月到 2014 年 5 月和 2015 年,使用隔膜泵在 7 和 10 个地点收集了角膜白斑卵。栖息地适宜性模型显示,
