A further update from the MPI:
MPI has just received reports that some lamprey migrating up the Mataura River in Southland this year appear to have similar skin markings to those present on lamprey last spring.
When we put our activities on hold last year, the intention was to monitor future lamprey migration activity should the issue reoccur. We’re planning to send out a small team of scientists to collect suitable samples to carry out the necessary laboratory testing to once again try to identify what’s going on.
In the coming weeks we plan to work with other agencies, local authorities, tangata whenua and industry groups to identify and manage any biosecurity issues. We aim to provide you updates on our progress as we understand more about the situation. Bear in mind that it may take a number of weeks to gain any useful new information.
In the meantime, we recommend people finding lamprey with skin markings similar to those in the photos below immediately contact our 0800 free-phone – 0800 80 99 66. This will allow us to build up a picture of how widely distributed the problem is.
At this point, we plan to collect all necessary samples for laboratory testing, as the method of collection and processing is crucial to getting suitable samples. We do not need community members to submit dead or affected lamprey.
