Rocky reefs provide important spawning and refuge habitats for lithophilic fishes. However, many have been lost or severely degraded through anthropogenic effects like dredging, channelization, sedimentation. Constructed used to mitigate these in some systems, but are also subject degradation which may warrant custodial maintenance. Monitoring maintenance of natural constructed not common practices; therefore, few methodologies created test the effectiveness such tools. We conducted a...
Abstract Natural and anthropogenic sources of sedimentation have the potential to degrade spawning habitat negatively affect incubating fish embryos. Walleye Sander vitreus are lithophilic broadcast spawners that use specific habitats vulnerable degradation caused by deposition suspended sediments. We measured effect different types sediment cover on hatching success eggs assessed whether differences in female (female length mean egg size) account for tolerance cover. Experiments were...
Abstract Rocky reef habitats in lacustrine systems constitute important areas for lithophilic‐spawning fishes. Interstitial spaces created by the structure of rocky reefs form microenvironments where incubating embryos and juvenile fish are potentially protected from predators physical displacement. However, if interstitial filled or blocked sediment biofouling, may lose these benefits. Common practices to restore habitat include augmentation existing structures construction new reefs,...
ABSTRACT Optimal egg size theory implies that female organisms balance between fecundity and individual offspring investment according to their environment. Past interspecific studies suggest fishes in large marine systems generally produce smaller eggs than those small freshwater systems. We tested whether intraspecific variation reflected a similar pattern by comparing among yellow perch ( Perca flavescens ) populations inhabiting range of system sizes. In 2018, 2019, 2023, we collected...
