About the event

The Giant Freshwater Crayfish is listed as an endangered species on the IUCN Red List due to overfishing and habitat degradation, and it has been prohibited to catch it since 1998. The crayfish move up and down streams for feeding and breeding, but it appears - based on sightings by residents - that they are unable to use under road culverts, and instead are getting out of the stream and crossing the road, to get to the stream on the other side of the road. 

This project, undertaken by Todd Walsh, surveyed priority under-road culverts in the Kentish Municipality to determine whether or not they are accessible to crayfish. 

Todd will outline his findings at this presentation and propose remedial actions.
