9 Partnering in Fisheries Management Cooperative assessments of inland lake walleye populations are a prime example of inter-agency coordination. Large-scale population surveys are undertaken each spring and fall. Data are exchanged, reviewed through inter-agency committees, and reported to the public. Managers calculate population estimates and determine allowable harvest levels for both tribal and state fisheries. Managers also monitor population trends, establish on-going population monitoring protocols, and prepare harvest reports. Walleye population assessments use electrofishing equipment to collect, fin-clip and then recapture fish. Biologists estimate population size using standardized statistical protocols. Here, a GLIFWC tribal crew dips for fish and an 1854 Treaty Authority crew “works-up” its catch before returning the fish to the water. This graph integrates, in a convenient way, data resulting from cooperative walleye population assessments and monitoring activities in the Wisconsin ceded territories. It reports on overall population size (light blue), state harvest (dark blue), and the comparatively small tribal harvest (green). Joint tribal, state, federal and localfisherymanagementefforts yield comprehensive knowledge about a shared resource, building a better foundation for informed management decisions by all concerned.
