Scientific research for the conservation of the species
The Biodiversity Science Section of the Great Lakes Laboratory for Fisheries and Aquatic Sciences will be conducting a survey of larval fishes in the East Sydenham River. This survey will occur at four locations between Alvinston and Dawn Mills, Ontario. This survey will involve placing stationary, larval drift nets into the Sydenham River for timed surveys each day for a period of three months (~12 weeks).

Location of Activity (province, territory or ocean):
a) There are not alternatives to this research. Larval fishes cannot be identified in the field and only can be identified in the lab or using genetic analysis of samples. The emergence of larval fishes in relation to degree day is critical to informing the long-term recovery of all these species. This research is important to determining critical growth data as it relates to fish spawning timing, gonad development, larval fish emergence and larval drift. This critical research is important to the management fishes at risk. Further this research is a pilot for future fish species at risk larval research in Canada. b) Measures to minimize impact: Sampling will be limited to a total of 30 minutes per day per site. This amount of sampling is minimal. The goal of this project is to detect the emergence/drift of larval fish species at risk. If field crews begin to catch larger volumes of larval fishes than anticipated sampling times will be adjusted to reduce potential impacts to local populations. Unionid Impacts: These nets will be placed on in the water on posts. These posts will be pushed into the streambed to support the drift nets. Care will be taken to not impact species at risk mussels that may reside at the larval fish sampling locations. c) The proposed activities will not jeopardize the survival or recovery of these species as the techniques to be used are anticipated to capture few individuals during the survey. This information will be used to inform important early life history questions for Northern Madtom, Eastern Sand Darter, Blackstripe Topminnow, Spotted Sucker. No habitat of these species will be impacted during this research.
