Landscape Structure And Dynamics Of Recreational Fisheries, Christine N. Ruskamp
Landscape Structure And Dynamics Of Recreational Fisheries, Christine N. Ruskamp
School of Natural Resources: Dissertations, Theses, and Student Research
Angler populations and the waterbodies they use are patchily distributed, creating putatively complex user-resource dynamics on the landscape. Spatially and temporally dynamic relationships between anglers and waterbodies can be difficult to track, understand, and manage. We often focus our efforts on the angler (directly or indirectly) with far less attention devoted to understanding the spatial structure and dynamics of fisheries on the landscape. Waterbodies serve as dynamic attractors on the landscape, shaping landscape patterns in angler participation. We surmise that by understanding the spatial structure and dynamics of recreational fisheries we can gain tremendous insight to cross-scale patterns that shape …

The legacy of fish stocking in mountain lake ecosystems has left behind a challenge for land managers around the globe. In the US and Canada, historically fishless mountain lakes have been stocked with trout for over a century. These non-native trout have cascading ecosystem effects, and can accumulate atmospherically deposited contaminants. While the negative impacts of stocking in these ecosystems have become increasingly apparent, wilderness fishing has garnered cultural value in the angling community. As a result, public lands managers are left with conflicting priorities. National park managers across the western US are actively trying to reconcile the cultural and …
Australian Herring And West Australian Salmon Scientific Workshop Report, October 2017, Brent S. Wise, Brett W. Molony
Australian Herring And West Australian Salmon Scientific Workshop Report, October 2017, Brent S. Wise, Brett W. Molony
Fisheries research reports
A scientific workshop was held on 25th – 29th September 2017 to review available data for Australian herring (Arripis georgianus) and determine current stock status using the Department of Primary Industries and Regional Development’s (DPIRD) Risk-based Weight of Evidence Approach. Recommendations for future monitoring and assessments required to reduce uncertainties and establish sustainable catch levels were also made. Similar discussions were undertaken to establish monitoring and assessment approaches for establishing sustainable catch levels for West Australian salmon (Arripis truttaceus). The workshop was attended by DPIRD and non-DPIRD scientists, fishery managers from DPIRD and South Australia, commercial …
Walleye Fishery Ecology In Lake Oahe Of The Dakotas, Eli Felts
Walleye Fishery Ecology In Lake Oahe Of The Dakotas, Eli Felts
Electronic Theses and Dissertations
Walleye Sander vitreus is among the most popular sport fishes in North America and is the most sought-after fish in both South Dakota and North Dakota. Lake Oahe, a large main stem Missouri River reservoir, spans state boundaries and provides one of the most popular and productive Walleye fisheries in both Dakotas. The Walleye population of Lake Oahe has experienced wide fluctuations in abundance and size structure over the last 25 years which has caused high variability in angler use and satisfaction. Much of this variation is thought to be driven by Rainbow Smelt Osmserus mordax, which are the dominant …
