Scientific research for the conservation of the species
The research project will assess population assignment of striped bass in the area where the St. Lawrence River and southern Gulf of St. Lawrence populations overlap. 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 360 striped bass from both populations will be sacrificed, with approximately 20% of them coming from the St. Lawrence River population.

Location of Activity (province, territory or ocean):
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 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 not yet been 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. The mesh size of the gillnets will be adjusted to minimize bycatch, and the gear will be deployed for only the minimum time necessary to catch the number of specimens required. 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 striped bass from the St. Lawrence River 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.
