By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] WINNER: 2014 Best Paper, North American Journal of Fisheries Management Phenology is the study of cyclic and seasonal natural phenomena, especially in relation to climate. Although everyone understands it intuitively (imagine looking for the first crocuses emerging from under the snow in your yard), it... Read More
By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] WINNER: 2014 Best Paper, North American Journal of Aquaculture As a practical matter, fish culturists often need to spawn fish artificially, and this is especially true of the catfish industry where hybrids of Blue Catfish Ictaluras furcatus and Channel Catfish Ictaluras punctatus are preferred for...

By Jeff Schaeffer | AFS Co-Chief Science Editor The stone crab Menippe spp. fishery is one of the most unusual fisheries in the world, because only claws are harvested, and animals are released to remain in the fishery via survival and claw regeneration. Florida accounts for the majority of landings, and there both claws can... Read More
By Jeff Schaeffer, AFS Co-Chief Science Editor The upper Laurentian Great Lakes were separated physically from the Atlantic coast by Niagara Falls, but constructed ship canals allowed marine invaders to penetrate the system. Invading Sea Lampreys Petromyzon marinus decimated native piscivores during the 1940s, which allowed Alewife Alosa pseudoharengus to proliferate to nuisance levels of... Read More
By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] Management of many fish species requires good recruitment estimates; this is especially true for Gulf Coast reef fishes that are harvested intensively. One of the most important of these is Gray Snapper Lutjanus griseus, which are a primary target of nearshore fisheries in Florida. Gray... Read More
By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] Ethanol production has increased 13-fold from 2000 to 2013, and this has resulted in a concurrent increase in distillers dried grains (DDG), which are a byproduct of the fermentation process. While long used as feed for cattle, they have not been used widely in aquaculture... Read More
By Jeff Schaeffer | AFS Co-Chief Science Editor. E-mail: [email protected] Fish culturists struggle constantly with preventing and treating disease, but one helpful trend is the development of assays that can provide rapid diagnostics so that disease presence can be verified or treated. Saranya Plaon and colleagues at the Srinakharinwirot University (Thailand) present a great look... Read More
When you think of a national park, you probably have a vision of a place that is mostly pristine and untouched. So when Parks Canada took on the task of trying to eradicate the invasive Brook Trout Salvelinus fontinalis from the Middle and Lower Devon lakes, which form part of the headwaters of the Clearwater...

As an anadramous species, Atlantic Salmon Salmo salar have a complex life history that includes spending part of their lives in freshwater, estuarine, and marine habitats. In recent years, the decline of Atlantic Salmon has been attributed to their poor marine survivorship, due in large part to climate change. However, factors contributing to their marine... Read More
By Sarah Harrison | AFS Contributing Editor. E-mail: [email protected] Clifford Hutt (Mississippi State University, Human Dimensions and Conservation Laboratory) and his colleagues estimated both the economic impact (the monetary benefits of angling to the regional economy) and economic value (the value of a fishing trip above the angler’s actual costs; their net “willingness-to-pay” for the...
