All species inevitably leave genetic traces in their environments, and the resulting environmental DNA (eDNA) reflects present a given habitat. It remains unclear whether eDNA signals can provide quantitative metrics of abundance on which human livelihoods or conservation successes depend. Here, we report results large ocean survey (spanning 86 000 km 2 to depths 500 m) understand distribution Pacific hake ( Merluccius productus ), target largest finfish fishery along west coast USA.

Generating biomass-at-age indices for fisheries stock assessments with acoustic data collected by uncrewed surface vessels (USVs) has been hampered the need to resolve backscatter contemporaneous biological (e.g., age) composition data. To address this limitation, Pacific hake ( Merluccius productus ; “hake”) were gathered from a USV survey (in 2019) and acoustic-trawl (ATS; 2019 eight previous years), fishery-dependent non-target (i.e., not specifically targeting hake) fishery-independent...
Advances in acoustics technologies offer a remote and non-invasive sensing means to conduct fisheries acoustic surveys. Over the past two decades, joint US Canada trawl surveys on Pacific hake (Merluccius productus), one of most important commercial off West Coasts United States Canada, have been conducted at intervals three years within California Current System (CCS). In this presentation, temporal spatial distributions resulting from these spanning period nearly decades will be presented....
