Notice of permit

Regional or Local Number: MPO-LEP-QC-17-007

Notice is hereby given that pursuant to the provisions of section 73 of the Species at Risk Act permit no. MPO-LEP-QC-17-007 is issued.

Purpose:
Scientific research for the conservation of the species

Description:
The research project will assess population assignment of striped bass in the North Shore region, since no existing data indicates if it is the population of the St. Lawrence River or that of the southern Gulf of St Lawrence. The place of origin of the striped bass will be determined through an otolith microchemical analysis technique. To meet the study objective, the protocol states that a maximum of 120 striped bass will be sacrificed, probably from both populations.

Start Date: 2017-07-20   End Date: 2017-11-15

Issuing Authority: Department of Fisheries and Oceans

Authority Used:

  • Species at Risk Act

Location of Activity (province, territory or ocean):

  • Quebec

Affected Species:

Pre-Conditions:
a) Several alternatives were analyzed. Genetic testing is not feasible, since the St. Lawrence River population was reintroduced from the southern Gulf of St. Lawrence population. This reintroduction occurred too recently for the two populations to be genetically differentiated. Telemetry cannot be used to estimate the proportion of individuals from each population, mainly because of insufficient data collection and the atypical movement patterns of individuals tagged in the St. Lawrence River. Scale microchemistry was also assessed as an alternative, but the effectiveness of this method has yet to be demonstrated, especially for anadromous species. With current knowledge, otolith microchemical analysis is the only reliable method to achieve the study objective. b) All possible measures were taken to minimize any negative effects of this activity on the striped bass. The sampling protocol was optimized to sample only the minimum number of individuals to achieve scientifically valid statistical data. To avoid taking a high density of striped bass, the harvesting of individuals will take place mainly following notification from recreational or commercial fishers (bycatch) and fishway operators (dipnet catches). If gillnets are used, the mesh size will be adjusted to minimize bycatch, and the gear will be deployed for only the minimum time necessary to catch the required number of specimens. The protocol reduces the probability of catching and killing more specimens than are needed for the study. c) Effects on survival and recovery: The activity has no impact on the species' habitat. Mortality of the St. Lawrence River striped bass population caused by the study will not jeopardize the survival or recovery of the species, according to the experts responsible for management of the species, especially because there are several signs that the population is currently growing and because stocking is ongoing. Also, the study is taking place outside of the known range of the St. Lawrence River striped bass population.
