Scientific research for the conservation of the species
The Biodiversity Science Section of the Great Lakes Laboratory for Fisheries and Aquatic Sciences (GLLFAS) will be conducting a survey of Spotted Gar spawning habitat in Rondeau Bay, Ontario. Since 2015 the GLLFAS Biodiversity Lab has been tracking Spotted Gar to determine spawning locations in Rondeau Bay. This three year study will conclude in 2017 as the telemetry tags will stop working this year. The macrophyte component of this study will involve identifying spawning sites with telemetry tracking. Once sites are identified, a randomized search of these locations will be conducted to determine macrophyte preferences of Spotted Gar. Within each location 10 quadrat samples will be collected of aquatic macrophytes. Spotted Gar eggs may be encountered; eggs will be collected along with the macrophytes to be counted to determine egg density within each quadrat. Macrophyte species preferences for egg adhesion will also be assessed.

Location of Activity (province, territory or ocean):
a) The only alternative to this research is to identify the aquatic macrophytes in situ versus removal of the macrophytes. This is not very productive for a few reasons: 1) The water will be too turbid to accurately identify macrophytes within the sampling quadrats without removal; 2) Eggs will be difficult to observe in turbid conditions without macrophyte removal; and, 3) Early spring water temperatures will be cold (~15°C to 20°C) and field crew members may not be able to remain in the water for extended periods of time. This research is important to determining critical habitat data as it relates to fish spawning timing, identification of critical habitat areas and identifying components of those critical habitat areas. This research is important to the management of Spotted Gar in Canada. b) Measures to minimize impact: A very low impact to Spotted Gar habitat in Rondeau Bay is expected as a result of the macrophyte removal. The maximum number of sites to be used for this survey will be between 30 and 50 sites (depending on spawning observations). This would be a total area of disturbed habitat between 75 m2 and 125 m2 of habitat (2.5 m2 of habitat disturbed at each macrophyte survey area). This will result in less than 1/1000 of 1% of the total potential spawning habitat within Rondeau Bay being disrupted. c) The proposed activities will not jeopardize the survival and recovery of Spotted Gar, and are anticipated to sample a very small percentage of the total spawning habitat in Rondeau Bay. The nature of this survey will develop strong correlations to habitat and macrophyte preferences for Spotted Gar habitats. This includes species of macrophytes preferred for egg adhesion. Further, we also have temperature loggers installed in Rondeau Bay to help develop spatial cues for spawning and egg development. This information will be used to inform important early life history questions for Spotted Gar.
