Waldo; Herrmann, Bent (Journal article; Peer reviewed, 2018-03-30)This study evaluated how illuminating the headrope of a selective flatfish trawl can affect catches of groundfishes, including Pacific Halibut Hippoglossus stenolepis, in the U.S. West Coast limited‐entry (LE) groundfish ... -
The Efficacy of Illumination to Reduce Bycatch of Eulachon and Groundfishes Before Trawl Capture in the Eastern North Pacific Ocean Shrimp Fishery
Lomeli, Mark J. M.; Groth, Scott D.; Blume, Matthew; Herrmann, Bent; Wakefield, W. Waldo (Journal article; Peer reviewed, 2019-05-24)This study examined the extent that eulachon (Thaleichthys pacificus) and groundfishes escape trawl entrainment in response to artificial illumination along an ocean shrimp (Pandalus jordani) trawl fishing line. Using a ...
