Annual Meeting
Sponsors: USDA Forest Service, NOAA, Trout Unlimited Despite outcry over the detrimental effects of overgrazing by livestock on riparian habitats and endangered fish, grazing remains one of the most common uses of public land in the United States and contributes to the sustainability of rural economies and landscapes. But when is grazing overgrazing? The USDA... Read More
Sponsors: Australian Centre for International Agricultural Research, South East Asian Fisheries Development Centre The Mekong is one of the most unique and fascinating river systems in the world. It contains almost 1,000 fish species, which form a large proportion of the diet for almost 60 million people. The total capture fishery harvest is approximately 2... Read More
Unlike the “real world,” simulation models provide experimental systems where the outcomes of various assumptions can be examined to help inform management decisions. Given the multiple-objective nature of fisheries management, quantitative fish population and environmental simulations have become more commonly used to help cumulate the effects of multiple management actions and environmental stressors and provide...

Sponsor: Great Lakes Fishery Commission Increasing connectivity into and within rivers can benefit fishes by providing access to important habitats. Deliberate fragmentation of rivers can protect fishes by limiting the spread of invasive species. This symposium first addressed the geographic scope of interest in, and need for, selective bidirectional fish passage. It then explored the... Read More
Temperature is a critical component of freshwater ecosystems, influencing a wide range of phenomena from phenology of individuals to interactions within aquatic communities. This symposium brought together empirical data, statistical tools, and mechanistic models describing thermal regimes in aquatic systems, with the intent of determining which techniques are best equipped for understanding these regimes and...

The AFS scientists tackled a diversity of effects from anthropogenic eutrophication on U.S. fish and fisheries. Although several intertwining factors were discussed in this symposium, it was clear that we are only beginning to scratch the surface of this complex issue. This well-attended symposium began with a thought-provoking keynote that explored if the northern Gulf... Read More
Sponsor: Cramer Fish Sciences When we first imagined this symposium, we thought we’d invite enough speakers to fill one slot. Instead, there was enough interest among AFS members to fill an entire day. We had 19 talks that all addressed fish restoration. Speakers were agency and tribal scientists, academics, consultants, and students. Some talks were... Read More
More than a half century ago, researchers recognized that the sensory basis of navigation could be a powerful way to predict the movements and distribution of fishes. Recent work supports these earlier theories. Variation in the movements of homing salmon are accurately predicted by a biphasic strategy of fish using the geomagnetic field for oceanic... Read More
Large watersheds of western North America provide extensive habitat for Pacific salmon species. These fish are of great cultural, ecological, and economic importance to the peoples and ecosystems of these river basins. Some of these salmon watersheds remain relatively pristine while others have experienced decades of industrial development that have eroded their connectivity and productivity.... Read More
FISHBIO hosted a two-day symposium at AFS 2015 called “Keeping up with the Times: Advancements and Creative Solutions Using Applied Technology in Fisheries Monitoring and Research.” All the presenters provided enthusiastic updates on advancements and innovative uses of both older and new technology. The talks spanned a variety of fisheries technologies, including passive integrated transponder... Read More
