Book Description
Current populations of lake sturgeon (Acipenser fulvescens) are affected by many anthropogenic activities such as dams, pollution, development, and overharvest. Management and recovery efforts hinge on acquisition of basic biological data to better understand variation in recruitment. However, little information is available regarding differences in spawning time, egg development, and larval ecology between river systems that harbor remnant populations. The objectives of this study were to compare and contrast the relative production of larval lake sturgeon observed within and between populations over multiple reproductive seasons, and to evaluate whether there is evidence for morphological differences between larval lake sturgeon that have experienced quite different incubation conditions. Transects of standard D-frame drift nets were deployed below known spawning sites in both the Menominee River, Wisconsin in 2012, 2013 and 2014 (10 nets, evenly spaced along a 200 meter wide transect, 800 meters downstream from the Hattie Street Dam), and the Oconto River, Wisconsin in 2013, 2014 and 2015 (6 nets evenly spaced along a 60 meter wide transect, 1,250 meters downstream from Stiles Dam). A total of 4,442 larvae were captured across all seasons and both rivers. Significant differences were seen in both the number and length of larval lake sturgeon across the Menominee and Oconto Rivers. Rates of change in average body size were significantly different among annual drift events. This information had practical management connections to estimating population recruitment, as well as, providing a better understanding of lake sturgeon early life history patterns on a system by system basis.

Book Description
People of the Sturgeon tells the poignant story of an ancient fish. Wanton harvest and habitat loss took a heavy toll on these prehistoric creatures until they teetered on the brink of extinction. But, in Wisconsin, lake sturgeon have flourished because of the dedicated work of Department of Natural Resources staff, university researchers and a determined group of spearers known as Sturgeon For Tomorrow. Thanks to these efforts, spearers can still flock by the thousands to frozen Lake Winnebago each winter to take part in a ritual rooted in the traditions of the Menominee and other Wisconsin Indians. A century of sturgeon management on Lake Winnebago has produced the world's largest and healthiest lake sturgeon population. Through a fascinating collection of images, stories and interviews, People of the Sturgeon chronicles the history of this remarkable fish and the cultural traditions it has spawned. The authors introduce a colorful cast of characters with a good fish tale to tell. Color photos by the late Bob Rashid and images from the Wisconsin Historical Society evoke both the magical and the mortal. Weaving together myriad voices and examining the sturgeon's profound cultural impact, the authors reveal how a diverse group of people are now joined together as "people of the sturgeon."

Book Description
Abstract : The Menominee River is a Michigan-Wisconsin boundary water historically traversed by lake sturgeon (Acipenser fulvescens), but now contains fragmented populations between hydroelectric dams. Though fish passage is currently being implemented on the lower dams, it is unclear whether sturgeon given access to historic spawning grounds would use them. In 2012 and 2013, a total of 15 pre-spawning sturgeon were captured, implanted with sonic transmitters and translocated upstream over two hydroelectric dams to the stretch below the historic spawning site of Sturgeon Falls. Sturgeon were then tracked via five stationary receivers from April 2012 until August 2013, and with a portable receiver April to September 2012 and May to August 2013. Abiotic habitat features, including water depths, temperatures, present substrate particle classes, dissolved oxygen, and light intensities near the river bottom, and biotic features including invertebrate sampling and vegetation mapping were also collected. Within 2 weeks of translocation, seven of the study sturgeon were detected near the historic spawning site, where sturgeon spawning behavior was observed both study years. Within 48 hours of translocation, the remaining 8 study sturgeon all migrated at least 10 rkm upstream, near two other potential spawning sites within the study area. Habitat measurements suggest that the study stretch contains suitable habitat for year-0, juvenile, and adult lake sturgeon. In-stream vegetation appeared to create a barrier to sturgeon movement in 2012, but did not in 2013 when observed vegetation was at half the coverage as the previous year. This study has found that if pre-spawning sturgeon from an impounded stretch of river are given access to historic upstream spawning habitat, they will migrate to this habitat. Sturgeon spawning activity near Sturgeon Falls Dam was observed in both study years.
