Mike Ostrander, a local captain who has been guiding blue catfish fishing trips for 17 years, has noticed this decline in trophy-size fish landed. As a result, he has experienced a 50 percent drop in business.
“The James River at one point was a nationally recognized trophy fishery for blue catfish. I can’t say for certain why there was a drop in the biomass of large catfish, but it is likely due to a number of different reasons. I think one of the first things that happened, years ago, was some kind of market developed for the large catfish. I believe some of the larger catfish were being captured from the river and transferred to trophy lakes around the county,” Ostrander says.
Science tends to back up the anglers’ distress. In 2006, the Southeastern Association of Fish and Wildlife Agencies Journal published a study calling attention to the difficulty for blue catfish to reach trophy weights and lengths. This element of ecology makes it easier for the harvest of large individuals to destroy the trophy fishery in a given location. In response, some Midwest states have restricted their harvest to preserve the economically valuable fishery.
Ostrander also believes that pollution from coal ash dewatering, trawling that kills endangered species when they get caught as by catch, and dumping raw sewage into the river following heavy rains, makes humans more invasive than the blues. “I think people, not catfish, are the main cause of the demise of the native species,” he adds.
Ultimately, Ostrander says, “the catfish are likely doing something, but it’s probably nothing compared to the poor water quality they have to survive in.”
