Research explores recreational shark fishing's impact on protected species

In Delaware, recreational shark fishing is popular, with anglers taking part in half- and full-day shark fishing trips. However, they are prohibited from keeping protected species of sharks.


A University of Delaware research team led by Aaron Carlisle, assistant professor in UD's School of Marine Science and Policy (SMSP), is studying the impact of releasing these sharks, aiming to understand their post-release survival and how fishing operations handle them. Carlisle, graduate student Bethany Brodbeck and Ed Hale, assistant professor and aquaculture specialist for Delaware Sea Grant, are conducting the field research for the study, riding along with recreational fishing vessels to better understand what happens to sharks when they are caught and released.


Another component to the research is being led by George Parsons, E.I. du Pont Professor at UD’s College of Earth, Ocean and Environment, who is looking at the economic aspect, using survey-based research to value the shark fishery and study anglers’ perceptions and attitudes toward sharks and their management.


Carlisle said the two concurrent studies will help gauge the biological and economic impacts of the shark fishery in Delaware.


“We want to find out how much money the fishery is actually drawing to the economy,” Carlisle said. “We also want to find out how the fishery is actually impacting the populations of sharks in Delaware, especially the protected ones.”


The research was funded by Delaware Sea Grant, which helps communities wisely use, manage and conserve coastal resources.

Researchers find ‘narrow’ depictions of fatherhood in children’s literature

When children read picture books, they are often greeted with depictions of family and life lessons their young minds soak up. What happens then, when those depictions don’t offer a thoughtful image of gender or family as they have changed over the years? That is one of the questions University of Delaware Professor Bill Lewis and Social Science Research Analyst and UD alumna Laura Cutler explored in their recent paper, published in the quarterly journal Children's Literature in Education. In “Portraits of Fatherhood: Depictions of Fathers and Father–Child Relationships in Award-Winning Children’s Literature,” Lewis and Cutler looked at more than 80 children’s books to analyze how authors and publishers depicted fathers and fatherhood. What they found was that over a span of nearly 20 years, from 2001 to 2020, these books presented "a narrow view of fatherhood," both in what roles fathers have in familial units and which types of fathers are presented. They also noted that these portrayals have remained relatively static over the last two decades. Lewis, a professor in the College of Education and Human Development’s School of Education, broke down what spurred the research and what he and Cutler hope changes as a result of the research in a new Q&A.

Professors address students' climate anxiety

Professors at the University of Delaware preparing students for careers working on climate change are making sure to consider mental health issues as they send them out into the world. UD's Climate Change Science and Policy Hub, led by director A.R. Siders, is starting a series of initiatives – on campus and in the region – to tackle the challenge of what is known as climate anxiety. This involves traditional trainings but also innovations with creativity, art, video games and play. "Learning about and working on climate change causes climate anxiety, ecogrief, solastalgia – there’s a whole new set of terms being created just to describe the problem," said Siders, also an associate professor in UD's Disaster Research Center and Biden School of Public Policy and Administration. "This is a real mental health concern." This new way of approaching climate education has become even more critical as universities expand climate education – such as new climate schools, degrees, courses and even embedding it in general education courses, Siders said. The U.S. government is supporting a growing climate workforce, and it is expected that more people will work in climate-related careers.

Those flying spiders are harmless; don't tell that to arachnophobes

A breed of flying arachnids known as Joro spiders are headed to the northeast this summer, specifically Pennsylvania, New Jersey and Delaware. Experts say there's nothing to fear, but that doesn't make them any less scary to those who have an issue with the eight-legged bug eaters. Two University of Delaware experts can provide insight and (some) comfort regarding any potential risk to humans. Brian Kunkel, an expert in landscape and household insects and entomology for ornamentals with UD's Cooperative Extension, confirmed the yellow and black spider will be making its arrival in the Tri-State area but said it isn't likely to be noticed until the fall, when it grows to visible size. Regardless, there is no need to be concerned. In the unlikely event that it bites, you would feel something akin to a bee sting, Kunkel said. Doug Tallamy, professor of entomology and wildlife ecology, confirmed the spiders are on the way but echoed Kunkel's assessment that there is nothing to be worried about. To set up an interview with Kunkel, send an email to mediarelations@udel.edu. If interested in an interview with Tallamy, visit his profile and click on the contact button.
