ABSTRACT: The United States has a small net-pen salmon industry dating back over 40 years and a nascent net-pen industry for other marine fish. The United States net-pen aquaculture sector has improved its resource efficiency in terms of the amount of fish meal and fish oil used in feeds and reduced its environmental impacts in terms of the mass loading...

RESUMEN: Los Estados Unidos de Norteamérica (EE. UU.) poseen una pequeña industria de acuacultura de salmones mediante jaulas de red que data desde hace cuatro décadas y una incipiente industria de cultivo con jaulas de otras especies de peces marinos. El sector de la acuacultura con jaulas de red en los EE.UU. ha mejorado la eficiencia de sus recursos en términos... Read More
RESUMEN: En noviembre de 1991, el Servicio Nacional de Pesquerías Marinas de los Estados Unidos de Norteamérica, ingresó al salmón (Oncorhynchus nerka) en el Acta de Especies Amenazadas de los Estados Unidos (AEA) bajo la categoría de amenazado. Los últimos remanentes conocidos del stock del Río Snake, regresaron al Lago Redfish, Valle Sawtooth, en la... Read More
ABSTRACT: In November 1991, the U.S. National Marine Fisheries Service listed Snake River Sockeye Salmon (Oncorhynchus nerka) as endangered under the U.S. Endangered Species Act (ESA). The last known remnants of the Snake River stock return to Redfish Lake in the Sawtooth Valley in central Idaho. In the ensuing two decades since the ESA listing,... Read More
Saul Greenberg and Theresa Godin Estimating angling effort on more than a few lakes can be prohibitively expensive using creel surveys and often requires finer-scale angler distribution data than aerial surveys can provide. An alternate method uses remote cameras to capture images of lakes at hourly intervals over long time periods. Technicians then visually analyze... Read More
Jake Rice, Michael J. Bradford, Keith D. Clarke, Marten A. Koops, Robert G. Randall, and Roger Wysocki In 2012, Canada’s Fisheries Act was amended. New fisheries protection provisions provide for the sustainability and ongoing productivity of commercial, recreational, and Aboriginal fisheries. These provisions replace previous provisions that focused on fish habitats, and concerns have been... Read More
Derek P. Crane, Loren M. Miller, James S. Diana, John M. Casselman, John M. Farrell, Kevin L. Kapuscinski, and Joe K. Nohner New research techniques and changing Muskellunge Esox masquinongy and Northern Pike E. lucius fisheries have contributed to paradigm shifts in the science and management of these species. A symposium on Muskellunge and Northern... Read More
We compare results of Great Lakes charter captain surveys from 2002 and 2011. Charter trips declined 27%, from over 103,000 in 2002 to less than 76,000 in 2011. Revenues between the two years fell 24%, from US$48.0 million to $36.4 million, after values were adjusted for inflation. An estimated 1,696 captains operated as a small... Read More
From 2002 to 2011, the number of charter fishing trips in Michigan waters of Lake Huron declined by 51%. Declines in catch rates, rising gasoline prices, and the economic downturn have been suggested as possible reasons for this decline. To better understand the relative importance of these factors, five catch-based and six economic variables were... Read More
The North Carolina charter boat fishery was surveyed in 1978 and provided a comprehensive assessment of the species catch composition and economic impacts. This fishery was surveyed again in 2007–2008 to provide a more recent representation of the effects and impacts on tourism and coastal fish populations. We analyzed and compared the species catch composition,... Read More
