Notice of permit

Regional or Local Number: 17-PCAA-00011

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. 17-PCAA-00011 is issued.

Purpose:
Scientific research for the conservation of the species

Description:
This is a monitoring project to investigate the use and suitability of newly created wetland sites at Crown Marsh; sampling will occur annually. Study design permits characterization of successional changes. Each summer, fishes are sampled by five hauls of a bag seine within a 75 m2 area, enclosed by a block-net. At each site, fish and macrophyte sampling take place at 10 randomly selected points. Visual estimates are used to characterize aquatic macrophyte species composition and submersed plant coverage. The same sampling methods will be applied to: 1) inventory fishes in currently isolated ponds; and, 2) characterize changes to fish assemblage composition over a three-year period after isolated ponds are connected to Long Point Bay.

Start Date: 2017-04-10   End Date: 2017-11-01

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: Other gear types have been identified as appropriate for the collection of fishes at risk in wetland habitats including: boat electrofisher, hoop-net, and trap-net (Portt et al. 2008). However, a standardized seining protocol has been already implemented during the first phase (2012-2014) of this monitoring study. Therefore, the same seining approach will be applied in order to ensure data consistency. b) Measures to minimize impact: All fishes, when captured, will be transferred from nets to buckets of clean water. During processing, fishes will be held in multiple tubs or buckets to reduce overcrowding. Water in buckets will be changed every 10 minutes. All fishes will be released after processing. c) Effects on survival and recovery: Sampling will not negatively affect Lake Chubsucker, Pugnose Shiner, and Spotted Gar populations. Individuals will be released after processing. The project directly supports the following Government-led recovery actions identified in Government Response Statements for Lake Chubsucker and Pugnose Shiner: investigate the effectiveness of coastal wetland restoration activities to recover Lake Chubsucker populations; investigate the effectiveness of coastal wetland restoration activities to recover Pugnose Shiner populations.
