“…Spawning timing for the Lake Sturgeon population in Cayuga Lake matches the spawning pattern of the St. Lawrence River source population for these stocked fish [15,13] and in other sturgeon populations [21,24]. Water temperatures and flow regimes are the key cues for Lake Sturgeon spawning [4,20] and were appropriate in Fall Creek in June 2017 (Figure 1). Both live eggs and larvae were collected from the sample site and spawning adults selected areas for egg deposition that had a greater proportion of gravel substrate than was generally available within the study area.…”

In June 2017, we documented the first observed spawning event by a reintroduced population of Lake Sturgeon (Acipenser fulvescens) in Fall Creek, a tributary to Cayuga Lake, New York, USA. This is the first observed spawning encounter of adult Lake Sturgeon since the beginning of the multi-agency Lake Sturgeon restoration effort in Cayuga Lake initiated in 1995 by the New York State Department of Environmental Conservation. Lake Sturgeon egg deposition was found specifically on substrate mainly composed of gravel sized rocks with depths and flows that made up a unique microhabitat combination within the creek which is not typical of habitat identified in other Lake Sturgeon spawning habitat studies across the Great Lakes. An estimated 810,052 ± 24,386 eggs were deposited in the sampled area of Fall Creek. The identified, potentially productive spawning microhabitat type in Fall Creek is likely to be widespread in similar tributaries around Cayuga Lake as well as small tributaries to other Finger Lakes and Lake Ontario. Ongoing research is focused on the evaluation of the extent of Finger Lakes habitat similar to that identified in Fall Creek. This microhabitat evaluation of sturgeon spawning and the broad scale landscape knowledge of tributary habitats, should support subsequent management to restore Lake Sturgeon.

“…For example, Lake Sturgeon may be slower to respond to new habitat than many other species inhabiting the river. Only recently has there been evidence of Lake Sturgeon spawning in the St. Marys River near the Main Rapids (Roseman et al 2020). Their population size was estimated to be <500 individuals (Bauman et al 2011) in the river and individuals spawn every 4–5 years, which suggests that perhaps as few as 100 individuals may be spawning in any given year.…”

Aquatic habitat has been extensively altered throughout the Laurentian Great Lakes to increase navigation connectivity. In particular, the St. Marys River, a Great Lakes connecting channel, lost >50% of its historic rapids habitat over the past century. In 2016, the natural flow was restored to the Little Rapids area of the St. Marys River. The goal of our study was to evaluate physical and ecological responses to the restoration of the Little Rapids area. Extensive habitat and biological data were collected prior to restoration (2013 and 2014), and after restoration (2017 and 2018). Measured parameters included total suspended solids, current velocity, benthic macroinvertebrates, and larval, juvenile, and adult fishes. Total suspended solids stayed low (<4 mg/L) following restoration, with the exception of a single construction‐related event. Pre‐restoration data indicated that all measured velocities were below the target flow rate of 0.24 m/s, whereas 70% of the measured habitat was above the target flow post‐restoration. Abundance and richness of benthic macroinvertebrates were reduced following restoration (>90% reduction). We observed a 45% increase in richness of larval fish 2 years after restoration and a 131% increase in catch per unit effort. For adult fishes, the proportion of individuals with a preference for fast‐moving waters increased from 1.5 to 45% in the restored area, and from 7 to 15% upstream of the restored area; a similar response was observed for lithophilic spawners. The physical and biological conditions of the Little Rapids improved and resembled conditions typical of rapids habitat extent in other areas of the river and other systems.

“…28 Johnson et al (2006) is 1,296 m 2 . 32 There were many differences in methodologies among the larval studies (Table 2.6), especially the number of nets used and duration of sampling. Certain studies did not include the number of nets deployed (Auer and Baker 2002;Roseman et al 2011Roseman et al , 2020, while others had multiple nets spaced across the entire river width (D'Amours et al 2001). Further, all studies appeared to sample through the entire duration when larval Lake Sturgeon would be drifting from the site, with the exception of the 2019 sampling of Roseman et al (2020) that only collected larvae on one day.…”

Fish Spawning Habitat Restoration Challenges and Management Options for the Laurentian Great Lakes

Freshwater fish populations are facing numerous threats including habitat loss and degradation. As such, much effort is devoted to restoring degraded habitats and restoring access to spawning habitats. In this thesis, I conducted a narrative review on sturgeon spawning habitat characteristics and biological productivity outcomes in support of functional monitoring for mandated offsetting measures. While sturgeon life history characteristics limit the feasibility of functional monitoring, this approach can be applied to other fishes. Biotelemetry was used to guide efforts for restoration of fish v Table of Contents ABSTRACT.
