Condition of Surgical Acoustic Tag Incisions in Recaptured Lake Erie Walleye (2011-2016) Intracoelomic implantation of electronic tags has become a common method in fishery research, but rarely are fish examined by scientists after release to understand the extent that surgical incisions have healed. Walleye (Sander vitreus) are a valuable, highly-exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n=926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed...

The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the region. To accomplish this, publicly available data, criteria derived from the regional managers and local stakeholders, and geospatial analysis were used to form an ecological model for spatial prioritization.

LEBS is the primary federal agency for applied fisheries science excellence in Lake Erie. From 2011-2013, LEBS carried out a project which addressed the effects of regional climate change on aquatic food webs in the Great Lakes. This study focused on Lake Erie, as it is a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate...

Since 2004, LEBS has participated in a collaborative, multiagency effort to assess forage fish populations in the western basin of Lake Erie. Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based based fishery management, and supports decision making that considers food-web interactions.

This range is significant in that it includes the year of peak abundance following recovery from ~4 decades of near extirpation (~1960 through the mid-1990s) through a period of decline. This range overlaps with fluctuations in abundance of other potentially relevant species, such as Round Goby and Dreissena spp. mussels. A novelty of these data is the separation of age classes, which provides for potentially novel approaches to assessing mayfly trends.

Measurements were made to complement data on fish egg deposition in the St. Clair-Detroit Rivers from 2005-2016. Depth measurements were made with a boat mounted sonar unit at the beginning of spring and fall sampling season from 2005-2016. Water velocities near the river bed were measured in 2013 and 2015 using a handheld velocity meter attached to a 6.8 kg sounding weight. The sounding weight was lowered off the side of a boat to the river bottom and then lifting the weight slighlty off the bottom to ensure the weight and velocity meter were properly oriented with the current, the mean velocity...

Collections were made using a 0.5 m diameter 153 um zooplankton net. Nets were lowered to ~0.5 m from bottom depth and retrieved. Nets were utilized with a General Oceanics flowmeter to calculate the distance the net traveled. At sites of collection, both temperature (degrees C) and Secchi depth (m) were collected for abiotic influencing factors of the zooplankton community. Collected specimens were narcotized in sugar formalin. Specimens were enumerated, identified, and measured under a dissection microscope. Volumetric estimates (m^-3) were obtained by applying the distance traveled and...
