2023 Alaska Fisheries Science Center Seminar Series -- Phil Ganz
The Nuts and Bolts of Catch Accounting
Estimates of catch for the various species that are encountered in Alaska's commercial groundfish fisheries are used by fisheries managers, stock assessment authors, and the public to gain a better understanding of harvest. However, not all data users may be familiar with the mechanics of how these estimates are generated. Because not all fishing activity in Alaska is monitored, NMFS has made decisions that determine what data are used to make catch estimates for unmonitored fishing. In this talk, I will give a mid-level overview of those rules. I will also show how these decisions manifest in terms of the frequency with which different types of fishing activities rely on estimates and the proximity in time and space that data used to produce those estimates come from. The goal of the talk is to illustrate how catch estimates in Alaska are currently generated in order to give data users a better understanding of them.
