Scientific research for the conservation of the species
Natural Resource Solutions Inc. (NRSI) will address existing knowledge gaps to improve understanding of the range and habitat of Pugnose Shiner. Targeted fish sampling will be performed through the use of a specialized electrofishing raft and seine net, sampling throughout tributaries of Lake St. Clair, including the lower reaches of Baptise Creek, Big Creek Drain, Little Creek, Ruscom River, Duck Creek, Bell River, Puce River, and Pike Creek. Sites will be selected based on site-specific water quality conditions to minimize risk of injury or mortality.

Location of Activity (province, territory or ocean):
a) Alternatives: There are no other sampling techniques that are as benign or effective as electrofishing (particularly where NRSI will be using a raft, which further reduces the impact on local benthic communities since the sampling platform floats and wading in water is not required), therefore no alternatives were considered. NRSI’s use of an electrofishing raft, rather than a backpack unit, further reduces the potential impact on benthic communities since no wading is necessary. By sampling within the known range for Pugnose Shiner, NRSI increases the likelihood of capturing the target species, which will provide beneficial information for recovery strategies and management plans. b) Mitigation measures for minimizing impacts during electrofishing sampling include using low-frequency pulsed direct current (to avoid fish spinal injury and asphyxiation) and proper fish handling techniques to avoid further injury once captured. Once captured, all fish will be maintained in a large, well-aerated holding tank with plenty of clean water until they can be released. Nets and proper gripping techniques will always be used, should an individual require handling. c) Effects on survival and recovery: NRSI is proposing to undertake a targeted sampling plan to detect the presence or absence of Pugnose Shiner within the tributaries of the south shore of Lake St. Clair. Sampling techniques and all activities associated with the project were chosen and designed to be as environmentally harmless as possible. Information gained through this research will help to increase the understanding of Pugnose Shiner populations in Ontario, which will allow more specific protection and recovery strategies to be designed, and will provide more detailed range data to inform management plans. The proposed research is anticipated to have an overall positive effect on the recovery of the species.
