Structured Decision Making 2022-2023 Egg-to-Fry Structured Decision Making Egg-to Fry Value of Information Interim Report: Influence Diagram and Qualitative Analysis To Advance Structured Decision-Making

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.

Join Us There are several opportunities to collaborate with the Partnership. Attend science-sharing events , including quarterly science webinars and annual science workshops. Visit the Events page for more information on recent and upcoming events. Participate in an ad-hoc group. The Partnership occasionally forms small groups to help with tasks such as planning science-sharing events or developing science activities. Become a member. Membership is open to those who meet the following eligibility criteria: Are resource agencies, NGOs, coalitions of constituents of the Sacramento River, academic research institutions. Membership will not include private consultants and private organizations. Manage or work on issues related to the Sacramento River and its fisheries and water management. Represent a credible voice in the Sacramento River community of resource managers and scientists. Sign the SRSP Charter. Commit to participate in Partnership and Science Subcommittee meetings and ad-hoc groups as appropriate.
