Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Morphometric and reproductive data from blue catfish (Ictalurus furcatus) collected in tributaries of the Chesapeake Bay, Maryland and Delaware 2020-2022 Morphometric and reproductive data from blue catfish (Ictalurus furcatus) collected in tributaries of the Chesapeake Bay, Maryland and Delaware 2020-2022
In this study, blue catfish were sampled from tidal reaches of the Chesapeake Bay in Maryland (Nanticoke River, Broad Creek, Marshyhope Creek, and Patuxent River) from March - October and at some sites, during specific times of the year. All fish were analyzed with histology to assess reproductive stage (immature, pre-spawn, and post-spawn) and plasma was collected for multiple endpoints...

Growth and Capture Mark Recapture Data from Giant Gartersnakes (Thamnophis gigas) in Rice Irrigation Canals 2018 to 2023 (ver. 2.0, July 2025) Growth and Capture Mark Recapture Data from Giant Gartersnakes (Thamnophis gigas) in Rice Irrigation Canals 2018 to 2023 (ver. 2.0, July 2025)
These data support a study modeling the growth, capture, and survival of giant gartersnakes (Thamnophis gigas). We captured giant gartersnakes inhabiting rice irrigation canals in the Sacramento Valley, California, USA from 2018 to 2023. We analyzed capture-mark-recapture data from 19 populations of giant gartersnakes sampled with an integrated growth-survival model. We tested how growth...
