Regional or Local Number: 19-PCAA-00016

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. 19-PCAA-00016 is issued.

Purpose:
Activity necessary or beneficial to the species

Description:
The objectives of the activities covered by the permit are to conduct a survey (seining and trawling) of the East Sydenham River to determine if Northern Madtom (Noturus stigmosus) still exists in this watershed. Previous recent surveys have been unsuccessful in detecting this species. The last known record of Northern Madtom in the East Sydenham River was from 1929 near Alvinston, Ontario, and from 1975 near Florence, Ontario. The other species listed on the permit may be captured incidentally during the surveys. The activities authorized by the permit consist of the capture of Northern Madtom from the East Sydenham River using a small mesh trawl and/or a small mesh seine net. The gear type used will depend on habitat conditions and water levels at each site. Identification and processing will involve the handling of Northern Madtom (count, measure, photograph etc.). After fishes are processed (identified, measured) they will be released back to the river, alive. Vouchers will be collected using digital cameras, but some vouchers of smaller fishes may be retained in 10% formalin to confirm identification, if digital vouchers cannot be collected. These survey activities may result in the incidental capture and handling of Eastern Sand Darter (Ammocrypta pellucida) and the species at risk mussels listed on the permit, for the purposes of identification and processing (count, measure, photograph etc.). Any species at risk incidentally captured will be returned alive to the location of capture.

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Ontario

Affected Species:

Pre-Conditions:
a) Alternatives: No other locations were possible for consideration, as the objective of the work is specifically to locate Northern Madtom in the East Sydenham River. Northern Madtom is a benthic species, and the only two effective gears for capturing it are small mesh seine nets or a small (<3 mm) mesh trawl. The gear types being proposed for this sampling have been successfully used to capture Northern Madtom in the Thames River, Detroit River, and St. Clair River. Seining and trawling have proven to be effective tools for capturing live Northern Madtom. b) Measures to minimize impact: Sampling mortality will be minimized by using well-trained Fisheries and Oceans Canada Science staff to deploy, capture, process, and release fishes quickly at each sampling event. All animal care best management practices will be adhered to during the sampling. Fishes will always be handled with care, and placed in fresh, clean water during processing. Between capture and release, fishes will be placed in fresh water and attention will be given to maintain fresh water for all specimens. After fishes are processed (identified, measured) they will be released back to the river. Vouchers will be collected using digital cameras, but some vouchers will be collected of smaller fishes using 10% formalin to confirm identification. This will only occur if digital vouchers cannot be collected. c) Effects on survival and recovery: The survey will have some minimal habitat disturbance from either seining or trawling. This will be a small area that is disturbed for a short period of time. Each gear type (trawling or seining) disturbs an area less than ~100 m2 each time. Few mortalities are anticipated. Provided the mitigation contained in the description of activities and the permit issued under section 73 of the Species at Risk Act, the project will pose a low risk and will not jeopardize the survival and recovery of the species. The proposed techniques are anticipated to capture few individuals, if any, during the survey due to the rarity of these species in the targeted reach of the East Sydenham River. This survey will have no impact on local populations if any individuals are found.
