The Sandusky River, Ohio, USA, has experienced more than a century of alterations, including dam implementation and removal, causing cascade habitat changes. physical changes in the river led to establishment several invasive species. Ten hoop-net sampling sites, spaced about 500 m apart were established monitor fish assemblage their preferences. Four 10-d events completed from April through October 2021. Ordination analyses used assess fish-assemblage structure seasonably, species-habitat...
ABSTRACT Objective Invasive carps continue to spread across the Mississippi River basin, posing significant ecological risk. Identifying technologies slow their dispersal is critical. The use of sound has been proposed as a method modify behavior Silver Carp Hypophthalmichthys molitrix, offering nonstructural deterrent strategy. Methods implanted with acoustic transmitters were released into earthen ponds equipped telemetry arrays. fish exposed 30-min playback three underwater sounds (chirp...
Abstract Despite significant efforts devoted to understanding the underlying complexity and emergence of collective movement in animal groups, role different external settings on this type remains largely unexplored. Here, by combining time series analysis complex network tools, we present an extensive investigation effects shady environments behavior a fish species (Silver Carp Hypophthalmichthys molitrix ) within earthen ponds. We find that shade encourages residence during daylight hours,...
Abstract The role of offering a commercial pelleted diet has been characterized as both an expensive organic fertilizer and selected food item for larval hybrid striped bass (palmetto), Morone saxatilis × chrysops , culture operations. In this study, we examined the effects providing on fish production zooplankton dynamics during phase I in plastic‐lined ponds. We also sought to estimate relative dietary contribution feed natural pond biota using stable isotope tissue analysis. Palmetto were...
Abstract Trophic dynamics and conceptual niche spaces of top piscivores were assessed using stable isotope analysis following the introduction hybrid striped bass Morone saxatilis (Walbaum) × chrysops (Rafinesque) into an established reservoir fishery devoid gizzard shad, Dorosoma cepedianum (Lasueur). Hybrid initially stocked Three Mile Lake, Iowa as attempt to biologically control pervasive yellow bass, mississippiensis Jordan & Eigenmann, populations. From analyses, it concluded that...
Abstract Although there are many methods to determine ingestion and absorption of aquafeeds, none exist that simple, cost‐effective, quantitative can mark fish with a long‐lasting, visible indicator. In addition aquafeed development, selective baits needed be used for aquatic invasive species removal efforts, including Grass Carp Ctenopharyngodon idella . Bait incorporated pesticide would allow targeted species. A method quickly assess multiple bait formulations was developed expediate...
