As part of an attempt to reconstruct the original distribution and relative abundance of lake sturgeon in tributaries to Lake Michigan, old newspapers were surveyed for accounts of sturgeon captured by sport and commercial fishers. The reliability of this process was assessed in several ways. A historical column in a modern newspaper (De Pere journal) proved useful for identifying the time period during which original accounts of sturgeon were first published (late 1800s–early 1900s) and the season when most historical catches occurred (the spring spawning season), but a complete survey of the original newspapers revealed many more records than resurfaced in the historical column and some significant accounts that were published outside of the spawning season. Independent surveys of De Pere newspapers by different searchers revealed that the average searcher found a majority of known records (more than 90%). The seasonal distribution of catches in the Lower Fox River as revealed by historical newspaper accounts was very similar to that based on modern sightings, and the newspaper contained several accounts of sturgeon in other parts of the drainage or other parts of Wisconsin. However, comparison with newspapers published in the neighbouring community of Green Bay revealed that the latter included few of the incidents reported in the De Pere paper, and few additional accounts appeared in the Green Bay papers that were not reported in De Pere. Although the De Pere newspaper accounts taken alone reveal a history of sturgeon exploitation in this microcosm remarkably parallel to patterns of sturgeon exploitation nationwide, our initial focus on the De Pere paper appears to have been fortuitous in that few local newspapers along the Lake Michigan shoreline would have yielded comparable amounts of historical information.

Stock Differentiation

To evaluate the stock structure of yellow perch ( Perca flavescens ) in the southern basin of Lake Michigan and in Green Bay, we analyzed recaptures from a lake-wide mark–recapture study implemented from 1996 to 2001 to infer the range and pattern of movement and spawning-site fidelity. Yellow perch generally moved south along the western shoreline, west along the southern shoreline, and north along the eastern shoreline during summer and non-summer months; the magnitude of movement was greater after spawning. Spawning yellow perch frequently returned to the same site, with 35%–80% of recaptured individuals returning to their marking site. Results from multiple tagging sites within Illinois indicated that spawners may return to larger areas rather than to specific sites, suggesting that large spawning complexes exist. Despite strong fidelity in some areas, straying was evident from all sites during spawning, resulting in mixing throughout the southern basin. Such mixing could promote gene flow and diminish stock differentiation. Dispersal of yellow perch within the southern basin of Lake Michigan occurred regularly across adjacent management boundaries. Therefore, adjacent jurisdictions may wish to consider re-examining their regulations based on this information to ensure consistent, complementary regulations that incorporate the movement patterns of yellow perch.

Newspaper Data

ABSTRACT Old newspapers (1850–1915) in the Lake Michigan basin were surveyed for reports of large lake sturgeon (≥ 100 pounds = 45.4 kg). Records of large fish were obtained from throughout the basin. To assess the accuracy of reported measurements, reported weights associated with reported lengths were compared to weights predicted by a weight-length regression developed for a large sample of fish from Lake Winnebago. Although there were a few obvious or likely outliers in the historical Lake Michigan data set, reported and predicted weights were not significantly different. Moreover, although the mean magnitude of deviations between reported and predicted weights, expressed as a proportion of predicted weight, was substantial, it was comparable to natural variability among lake sturgeon due to the effects of differences between sexes, locations, times of year, and reproductive status.

Yolk Absorption

In fishes, environmental ion availability can have substantial effects on growth and development. This study examined the development of Lake Sturgeon in response to the varying environmental ion availability that they experience as part of a conservation stocking program. We reared sturgeon in natural water from the Coosa River, which had higher concentrations of Mg2+, Na+, and Zn2+ than standard hatchery conditions, while [Ca2+] at the Warm Springs National Fish Hatchery was 2× higher than in the Coosa River. Eggs were hatched in each water type and the larvae were sampled at time points before and after yolk absorption during the first 8 weeks of development. Total length and weight in WSNFH larvae were significantly higher than larvae in Coosa River water starting at 8 dph, indicating that growth was dependent on the different environmental ion levels. Concentrations of the ions of interest were also determined for whole-body acid digests of the exposed Lake Sturgeon. We found that Lake Sturgeon reared in Coosa River water had significantly higher magnesium and zinc than Lake Sturgeon reared in WSNFH water (p < 0.05), while calcium was significantly higher in WSNFH than Coosa River water. This difference shows that different environmental ion concentrations also impact the overall development of larval Lake Sturgeon.
