Variability in Fish Tissue Proximate Composition is Consistent with Indirect Effects of Hypoxia in Chesapeake Bay Tributaries

By Troy D. Tuckey and Mary C. Fabrizio The spatial and temporal extent of summer hypoxia (dissolved oxygen [DO] concentration ≤ 2 mg/L) in Chesapeake Bay and its tributaries has been increasing for decades, consequently affecting fish distribution and abundance by shifting biomass to non-hypoxic habitats. Hypoxia in coastal waters impacts food web dynamics, thereby... Read More

Back Page Photo Series: An Interview with Stacy Farina

Interview by Natalie Sopinka     What species of fish is in this image? This is a 3D volume rendering from a micro-computed tomography (CT) scan of a Scalyhead Sculpin skeleton. Computed tomography scanning is commonly used as a diagnostic tool in medicine, but it is also incredibly useful for studying the biology of animals.The... Read More

Green Lights Stop Sea Turtle Deaths

Illuminating fishing nets is a cost-effective means of dramatically reducing the number of sea turtles getting caught and dying unnecessarily, conservation biologists at the University of Exeter have found. Dr. Jeffrey Mangel, a Darwin Initiative research fellow based in Peru, and Professor Brendan Godley, from the Centre for Ecology and Conservation at the University’s Penryn... Read More

Fish populations revealed through seawater analysis

A research group led by Yamamoto Satoshi, a research fellow at the Kobe University Graduate School of Human Development and Environment, has shown that measuring quantities of fish DNA in seawater can reveal how many fish inhabit that environment. This discovery could enable quicker and more effective surveys of fish distribution, and has potential applications in... Read More
