Virginia Tech researchers in the College of Natural Resources and Environment are assessing the efficacy of shark sanctuaries by developing a modeling system that utilizes publicly accessible fishing data to determine shark catch and mortality rates. Published in the journal Science Advances, their findings represent an important step in utilizing data science to tackle oceanic conservation challenges.
their findings represent an important step in utilizing data science to tackle oceanic conservation challenges.designated by countries as places where the targeted fishing of sharks is prohibited," said Brendan Shea, a Ph.D. student in the Department of Fish and Wildlife Conservation and the paper's lead author.
To estimate catch and mortality rates for oceanic shark species, the research team utilized positioning data of fishing vessels from Global Fishing Watch, an open-access website that provides a global view of commercial fishing activities around the world to advance ocean governance. The group also collected publicly available data from regionalorganizations to create a model that would estimate the impacts of longline fishing on seven species of open-ocean sharks.
Shea, who collaborated with research partner Beneath the Waves, a nonprofit marine research institution, said that utilizing multiple streams of data to tackle a specific conservation question marks an important stride forward in fisheries research. Ferretti echoes that research like this marks an important inroad toward considering new approaches to understanding"This is an illustration of how we're transitioning from fisheries science to fisheries," said Ferretti."In the age of big data, we've demonstrated that we can do applied conservation and management research, and it is work that is applicable to many other aspects of fisheries management at large and even global scales.

Researchers create optical device that can kill pathogens on surfaces while remaining safe for humansWhile it has long been known that ultraviolet (UV) light can help kill disease-causing pathogens, the COVID-19 pandemic has put a spotlight on how these technologies can rid environments of germs. However, the excimer lamps and LEDs that can directly emit light in the required deep-UV wavelengths generally have low efficiency or suffer from short lifetimes. Moreover, UV light of the wrong wavelength can actually be harmful to human cells.
