Columbia River Basin Salmon And Steelhead Long-Term Recovery Situation Assessment, Oregon Solutions, William D. Ruckelshaus Center

National Policy Consensus Center Publications and Reports

In the fall of 2012, after consulting with a wide range of salmon recovery partners, NOAA Fisheries asked Oregon Consensus and the William D. Ruckelshaus Center (university-based, neutral, third-party institutions devoted to promoting collaborative governance and consensusbased public policy) to conduct an independent, impartial situation assessment to explore regional views about how best to approach comprehensive, long-term salmon and steelhead recovery in the Basin. The centers assembled an Assessment Team comprised of practitioners and academics from Washington, Oregon and Idaho.

The Assessment Team conducted 206 semi-structured interviews with individuals selected for their knowledge of, engagement in, and/or concern for salmon …

Ecosystem-Based Fisheries Management (Ebfm) Risk Assessment Of The Western Australian Abalone Managed Industry, F J. Webster, B Wise, Anthony M. Hart

WA Marine Stewardship Council report series

This report provides a comprehensive overview of the Western Australian (WA) Abalone Managed Fishery (AMF) and the outcomes from the 2015 ecological risk assessment of this fishery. The AMF targets three species of abalone greenlip (Haliotis laevigata), brownlip (H. conicopora) and Roe’s abalone (H. roei). Greenlip and brownlip abalone are primarily targeted on the south coast of WA, while Roe’s abalone is primarily targeted on the West Coast. Commercial fishing for abalone in WA has been undertaken since 1964.

Estimating The Number Of Recreational Anglers For A Given Waterbody, Kevin L. Pope, Larkin A. Powell, Brian S. Harmon, Mark A. Pegg, Christopher J. Chizinski

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Knowing how many anglers use a given body of water is paramount for understanding components of a fishery related to angling pressure and harvest, yet no study has attempted to provide an estimate of the population size of anglers for a given waterbody. Here, we use information from creel surveys in a removal-sampling framework to estimate total numbers of anglers using six reservoirs in Nebraska, USA, and we examine the influence of the duration of sampling period on those estimates. Population estimates (N ± SE) of unique anglers were 2050 ± 45 for Branched Oak Lake, 1992 ± 29 for …
