Removing Black Bullhead Using Collapsible Minnow Traps

The West Fork San Luis Rey River, located just north of San Diego, California on Palomar Mountain, is home to the southernmost population of native Coastal Rainbow Trout (Oncorhynchus mykiss irideus). In 2007, non-native Black Bullhead (Ameiurus melas) washed into the stream from a source population in a private stock pond located in the headwaters. While species of catfish are often difficult to eradicate in introduced systems, biologists from California Department of Fish and Wildlife successfully conducted a removal project from 2016-2018 and achieved complete bullhead eradication within this stream. This CCAST Webinar will share how biologists implemented a variety of techniques to successfully remove Black Bullhead and discuss implications for conserving a unique assemblage of native fishes and amphibians.
