Environmental DNA (eDNA) Detection of Aquatic Invasive Species in
Manitoba Lakes, a comparative analysis of microscopy and
DNA detection methods.
This study assessed the presence of three Aquatic Invasive Species (AIS) Dreissena polymorpha, Dreissena bugensis, and Bythotrephes spp. in samples collected between 2022 and 2024 from several lakes of the Manitoba basin using both conventional microscopy and environmental DNA analysis.
First report of ciliate epibionts (Suctoria) on the invasive Bythotrephes cederströmii (Schödler, 1877) in Canada. Author: Liudmila Aleaga Aguilera
There are currently two species (B. longimanus and B. cederströmii) found in many freshwater ecosystems across Canada. During the analysis of samples for the monitoring of aquatic invasive species in Manitoba, many individuals of B. cederströmii from Cedar Lake, were observed to be carrying suctorian ciliate epibionts in very high density.

Title: PREVENTING THE INTRODUCTION AND THE SPREAD OF FRESHW ATER INVASIVE INVERTEBRATES IN ONTARIO: ASSESSME NT OF THE PROPOSED INVASIVE SPECIES ACT (BI LL 37)
Because of the importance that policy development and implantation play in managing invasive species for their effective prevention and spread, a policy analysis of the proposed Ontario’s Bill 37 (“An Act respecting Invasive Species”) was conducted based on an extensive literature review, the interview responses with provincial government officials, and the results from the constructed nonnative species checklist. A total of 46 species were identified as having a high impact on the environment, according to the literature
