Pelagic fish communities (waters with depths >20 m) of Lakes Powell and Mead were examined quarterly from 1995 to1998 using vertical gill nets and a scientific echosounder. Nets captured a total of 449 fish consisting of striped bass (57%/45% [Lake Powell/Lake Mead]), threadfin shad (24%/50%), common carp (15%/4%), walleye (3%), channel catfish (2%), and rainbow trout (<1%). Each reservoir contained concentrations of pelagic species separated by expanses of habitat with few fish (<10 kg ? ha?1). Reservoirs experienced dramatic seasonal and annual fluctuations in pelagic biomass. Lake Powell?s biomass peaked at the Colorado River at 709.7 (�46.5) kg ? ha?1 and Lake Mead?s reached 291.9 (�58.2) kg ? ha?1 at Las Vegas...
This data set includes environmental and biological information on fishes collected using gill nets and otter trawls during day and night, as well as diet data for Striped bass and Sacramento pikeminnow obtained via gastric lavage. Sampling took place in and around Ryer Island, Suisun Bay, California during Winter and Spring of 2018.
Final Report: Data provision and projected impact of climate change on fish biodiversity within the Desert LCC
The four primary objectives of this project were to: (1) compile a dataset of fish occurrence records for the entirety of the Rio Grande drainage in the US and Mexico; (2) improve that dataset by reformatting dates, synonymizing species names to a modern taxonomy, georeferencing localities, and flagging geographic outliers; (3) for those species with sufficient data for modeling, create species distribution models (SDMs); (4) use the environmental conditions determined via those models to project the species distributions into the future under two climate scenarios. To accomplish those objectives, we compiled 495,101 fish occurrence records mined from 122 original sources into a single database. We then, on the...
