Complete Survey

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.

Development and evaluation of a habitat suitability model for young lake sturgeon (Acipenser fulvescens) in the North Channel of the St. Clair River, Michigan

We evaluated the quantity, quality, and spatial distribution of riverine nursery habitat for larval, young-of-year (YOY), and juvenile (<500 mm) lake sturgeon (Acipenser fulvescens) in the North Channel of the St. Clair River (SCR), Michigan, using habitat suitability modeling (HSM) and fish collections. This HSM was developed using georeferenced habitat information on substrates, invertebrate densities, benthic flow velocities, and water depth. High-quality habitat comprised 29.1% of the study area, primarily in river bends and other areas where water velocities were highly varied. In all, 283 larval lake sturgeon were collected, with the majority found in high-quality habitat (81%) and heavily clustered in three locations (91.2% of total catch). Substrate composition and benthic flow velocity were the best indicators of observed larval catch-per-unit-effort (CPUE) patterns. Available data on captured YOY and juveniles were used to corroborate modeled habitat output and revealed strong associations between modeled habitat conditions and young lake sturgeon presence. An abundance of suitable habitat for young lake sturgeon within the North Channel of the SCR suggests that lack of suitable spawning habitat or high mortality early in life limits recruitment success in this system.
