Parentage Based Tagging (PBT)

The SRSP’s Science Subcommittee has been charged with hosting a series of science sharing presentations focused on parentage based tagging (PBT). The goals of these presentations include:

Develop a shared understanding of PBT among a variety of audiences including scientists, field technicians, fishermen, water users, agency staff, and NGOs.
Develop a shared understanding PBT as a tool that can be used to meet a range of objectives using lessons learned from other regions and applications.
