.. Lasted 2 hours this year. That's over twice as long as last year As I think I've mentioned here, my wife and I own a cabin on Black Lake. Every February they allow 6 or 7 sturgeon to be taken by spear, through holes in the ice. Not our thing, but it's a fun tradition for the Black Lake community, and the nearby town of Onaway. Russian sturgeon eggs are caviar, off course. https://www.detroitnews.com/story/n...ns-thriving-northern-michigan-lake/115469020/ Onaway – It took just over two hours for the 2021 public sturgeon spearing season on Black Lake in northern Michigan to end. Seven sturgeon were claimed in that time on Feb. 6, appearing to show that the ancient species is thriving in the Cheboygan County watershed, according to the Traverse City Record-Eagle. Recreational fishing rules allow only seven of the fish to be taken from Black Lake, about 100 miles northeast of Traverse City. The largest weighed in at 61 pounds. Lake sturgeon are bottom-feeding fish that often live well past 100 years and grow past lengths of six feet. Estimates show the lake system’s adult sturgeon population may have nearly doubled over the course of the last several decades, said Dave Borgeson, fisheries biologist and northern Lake Huron unit manager for the Michigan Department of Natural Resources. “All our information indicates an upward trend in the population,” Borgeson said. Officials end the spearing season after the sixth fish, but a seventh sturgeon may be taken in the moments before the event is called. State officials reported about 570 people registered for the event. The Black Lake chapter of the nonprofit Sturgeon For Tomorrow works to preserve the species, educate the public and assist researchers with hatchery and tagging activities. It also organizes volunteers to guard spawning sturgeon in the Black River from poachers. “Sturgeon guarding has done wonders to protect the adult population when they are really vulnerable while spawning in the spring,” Borgeson said. Officials plan to survey Black Lake’s juvenile sturgeon population in 2023 to compare to data collected in 2013.
