Growing concerns with antibiotic resistance have increased the need for non antibiotic disease treatments. Atefeh Sheikhlar and colleagues challenged Sharptail Catfish Clarias gariepinus with the bacterium Aeromonas hydrophila and compared growth and survival among untreated controls, treatment with the antibiotic oxytetracyline, and varying concentrations of an extract of the Asian asthma- plant Euphorbia hirta that...

Technological advances have led to unprecedented insights into animal movements, and this study by Eric Richer and his colleagues added GPS capability to radio- frequency identification (RFID) tags to accurately determine near- exact locations of fi sh within streams such that far more precise estimates of habitat use are now attainable. As a bonus, it... Read More
To restore native fish populations, fisheries programs often depend on active removal of aquatic invasive species. Chemical removal can be an effective method of eliminating aquatic invasive species, but chemicals can induce mortality in nontarget organisms and persist in the environment. Read More
In recent months, talk of offshore aquaculture has been buzzing in the news and in Washington. While finfish and shellfish culture has flourished in state waters for more than a century, offshore finfish aquaculture has not kept pace. There are currently no large-scale commercial finfish net-pen aquaculture operations in federal waters. Congress and federal agencies... Read More

The Mississippi River is a multijurisdictional and multiuse resource that has been variously altered and is foremost managed for navigation and flood control throughout much of its 3,734-km passage from its origin at Lake Itasca, Minnesota, to its outlet at the Gulf of Mexico Read More
Bioenergetics modeling is a widely used tool in fisheries management and research. Although popular, currently available software (i.e., Fish Bioenergetics 3.0) has not been updated in over 20 years and is incompatible with newer operating systems (i.e., 64-bit). Read More
Commercial and recreational fisheries remain a strong contributor to the United States economy, according to the annual Fisheries of the United States report released today by NOAA. Saltwater recreational fishing remains one of America’s favorite pastimes and a key contributor to the national economy—with 9.6 million anglers making nearly 63 million trips in 2016, catching more than 371...

By Daniel C. Dauwalter, Kurt A. Fesenmyer, Robin Bjork, Douglas R. Leasure & Seth J. Wenger Remote sensing has been pivotal to our understanding of freshwater fisheries, and we review this rapidly changing field with a focus on satellite and airborne applications. Historical applications emphasized spatial variation in the environment (e.g., watershed land use and in... Read More
