Influence of Habitat Characteristics on Shore-Spawning Kokanee

Influence of Habitat Characteristics on Shore-Spawning Kokanee by Steven L. Whitlock, Michael C. Quist and Andrew M. Dux Abstract Sockeye Salmon Oncorhynchus nerka and kokanee (lacustrine Sockeye Salmon) commonly spawn in both lentic and lotic environments; however, the habitat requirements of shore spawners are virtually unknown relative to those of stream spawners. A laboratory experiment and.. read more →

A New Beginning for South African Native Fish

In an article in this month’s Fisheries, an international collaboration between AFS and South African institutions resulted in South Africa’s first non-native fish eradication using rotenone in February 2012 in the Rondegat River, a small headwater stream in South Africa’s Cape Floristic Region (CFR) that had been invaded by Smallmouth Bass. The CFR is a.. read more →

Boom and Bust in Lake Michigan

Lake Michigan’s balancing act Boom and bust: Nature is full of examples of what happens when the balance between predators and prey gets out of whack. But when that balance is between two nonnative species in the vastly altered ecosystem of the Great Lakes, puzzling patterns may emerge. In a recent paper in Transactions of.. read more →

David Bella—Plenary Speaker Abstract for the 144th AFS Annual Meeting

Systemic Distortion David Bella, Oregon State University, Corvallis I have been asked to succinctly convey some lessons involving two related problems not well addressed in your educations. First, distortion of information emerges on vast scales. Second, reductionism—reducing the character of wholes to the character of their parts—misperceives such distortions. Together, these two failures combine to.. read more →

Thierry Oberdorff—Plenary Speaker Abstract for the 144th AFS Annual Meeting

Patterns in Riverine Fish Diversity: A Macroecological Perspective Thierry Oberdorff,  Muséum national d’Histoire naturelle, Paris Here I develop a conceptual framework that views contemporary riverine fish diversity as a product of a series of filters operating at different spatial and temporal scales and combining different processes, the heart of which is the drainage basin. The.. read more →

Ana Parma—Plenary Speaker Abstract for the 144th AFS Annual Meeting

Leveraging Local Experience to Improve Sustainability of Global Fisheries: It Is Not About Tools But Processes Ana Parma, Centro Nacional Patagonico, Puerto Madryn Chubut, Argentina The quest for management approaches to achieve sustainable fisheries has often led to prescriptions of technical fixes and tools for assessment, harvest control, and regulation of access privileges, without due.. read more →

Louis Bernatchez—Plenary Speaker Abstract for the 144th AFS Annual Meeting

Think/Act Globally and Locally; The Essential Contribution of Basic Science Towards Improved Fishery Management Louis Bernatchez, Université Laval, Quebec City Economical and budgetary concerns are increasingly pushing government research funding toward utilitarian research with expected quick return for the industry at the expense of basic science. Investing in utilitarian research has obvious merits, yet this.. read more →

It’s a girl! Sonograms help endangered fish

Even fisheries scientists can have a difficult time determining whether a fish is male or female by just glancing at it. So, imagine if you had a hatchery full of several hundred fish that you hope to breed in order to sustain an endangered species. In a recent article in the North American Journal of.. read more →

What’s a Striped Bass Worth?

Every year, thousands of anglers travel to Southern reservoirs hoping to land a selfie-worthy enormous Striped Bass. But is the cost of stocking Striped Bass justified, especially when there are other species to fish for in these reservoirs that don’t require stocking? In a recent article in the North American Journal of Fisheries Management, scientists.. read more →

More than Mucus: The Hidden World of the Fish Microbiota

More than Mucus: The Hidden World of the Fish Microbiota By Andrea M. Larsen and Cova R. Arias All living organisms maintain a diverse community of microbes that live in association with mucus-covered surfaces including the digestive, respiratory, and urogenital tracts. These microbial communities are known as ‘microbiota’. We grow up viewing microbes as disease-causing.. read more →

Flood Effects on Road–Stream Crossing Infrastructure: Economic and Ecological Benefits of Stream Simulation Designs

Abstract: Stream simulation design is a geomorphic, engineering, and ecologically based approach to designing road–stream crossings that creates a natural and dynamic channel through the crossing structure similar in dimensions and characteristics to the adjacent natural channel, allowing for unimpeded passage of aquatic organisms, debris, and water during various flow conditions, including floods. A retrospective.. read more →

Little Chubs Migrate, Too

When you think of migrating fish, usually silvery salmon gracefully leaping up waterfalls in the Pacific Northwest come to mind. In fact, many freshwater fish migrate in order to spawn, even the small minnows and chubs of the large, muddy rivers of the Great Plains. These large rivers are now  interrupted by numerous dams, diversion.. read more →

How Do Fish Catch a Virus? They Eat It

Viral hemorrhagic septicemia virus (VHSV) is just as unpleasant as it sounds for fish, leading to considerable losses of fish both in the wild and at some European fish farms.  Unfortunately, this disease has recently spread to the Great Lakes region but scientists are still unsure how it is transmitted. In a recent paper in.. read more →
