Spatial and temporal survey of waterborne myxozoan parasites in the Lake Sammamish watershed, Washington, from 2019 - 2020

공공데이터포털

There is a fundamental knowledge gap on the distribution, prevalence, intensity, and ecology of salmonid myxozoan parasites in the Lake Sammamish watershed, Washington. To address this knowledge gap, we tested water samples for Ceratonova shasta, Parvicapsula minibicornis and Tetracapsuloides bryosalmonae DNA from 84 sites distributed throughout the Lake Sammamish watershed in fall 2019 and 74 sites in spring 2020. Our surveillance identified zones with high waterborne parasite loads and provides a proof of concept for this approach that could be expanded throughout the larger Lake Washington watershed.

Lake Ontario Mysis diluviana catch and length data, 2021-2022

공공데이터포털

This dataset contains Mysis count and length measurements from vertical whole-column net tows along a depth gradient in Lake Ontario and associated operation data. Sample dates occurred during August 2021 and June, July, and August 2022. Site depths ranged from 70 to 202 meters bottom depth. Sites were sampled using a paired day-night sampling approach. At each visit, the net was lowered to 2 meters from the bottom and raised to the surface. Two to three replicate tows were completed. These data can be used to estimate numeric density or biomass of Mysis, and are intended for use by fisheries managers, academia, researchers, and the public.

Light trap and larval trawl collection of bigheaded carp in the Missouri River Basin, 2016

공공데이터포털

In the Lamine, Moreau, and Little Chariton rivers, light traps were used to capture larval bigheaded carps moving into tributaries. Traps were set on a weekly basis in each river, at roughly 1-kilometer intervals up to 7 km upstream. Ichthyoplankton tows were done in locations near the confluence of each tributary with the Missouri River, and within the Missouri River itself. Data includes identification of larval fish, size, and developmental information of subsampled invasive carp species. Flow readings were taken at up to five points across the channel with a Marsh-McBirney flow meter, and water quality was measured at the surface with a YSI ProPlus before retrieval of light traps.

Active relocations and tagging data for Black Carp Mylopharyngodon piceus; 2019-2023

공공데이터포털

This dataset represents active relocations of acoustic and radio telemetry tagged Black Carp among the Mississippi and Missouri rivers near their confluence. These river segments consist of both open river and impounded habitat present during observed hydrologic conditions from 2019-2023. Relocations were primarily on a monthly interval with initial weekly relocations during the first year of the study. Data are available throughout various seasonal conditions to document timing of movements and habitat use in these large rivers.
