Research explores recreational shark fishing's impact on protected species

In Delaware, recreational shark fishing is popular, with anglers taking part in halfand 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.

Biography

Dr. Carlisle joined the University of Delaware in 2018 as Assistant Professor of Fisheries Ecology. His research focuses on how the abiotic and biotic environment and organismal biology interact to influence the behavior, distribution and ecology of species, and how these interactions impact their population dynamics, life history strategies, and ecosystem roles. He uses a variety of approaches and technologies, such as stable isotope analysis and biologging, combined in new ways to provide unique insights into marine species.

Dr. Carlisle is a graduate of Stanford University (Ph.D.), Moss Landing Marine Laboratories (M.S.), and Princeton University (A.B.). He is a member of the IUCN Shark Specialist Group and serves on the board of directors of the American Elasmobranch Society.

Multi-taxa marine isoscapes provide insight into large-scale trophic dynamics in the North Pacific

Progress in Oceanography

2023

Quantifying large scale trophic dynamics and interactions in marine systems remains a key challenge in ecological research and conservation, particularly in remote habitats which are difficult and costly to access. Stable isotope (SI) analysis has emerged as an effective tool for studying ecosystem interactions, especially when used to construct isotopic landscapes, or “isoscapes”.

Using pseudo-absence models to test for environmental selection in marine movement ecology: the importance of sample size and selection strength

Movement Ecology

2022

Understanding the selection of environmental conditions by animals requires knowledge of where they are, but also of where they could have been. Presence data can be accurately estimated by direct sampling, sightings, or through electronic tag deployments. However, absence data are harder to determine because absences are challenging to measure in an uncontrolled setting.

Understanding the selection of environmental conditions by marine predators requires knowledge of where they are, but also of where they are not. Tracking marine organisms is challenging because animals can only be detected when they are at the surface.
