Chill out: physiological responses to winter ice-angling in two temperate freshwater fishes

A large body of research has documented the stress response of fish following angling capture, however almost no work focused on the effects of capture in the winter via ice angling. Therefore, the SFEL conducted a study to examine physiological disturbance and reflex impairment following capture by ice-angling in two commonly targeted species, bluegill Lepomis macrochirus and yellow perch Perca flavescens.

Study links fish stress hormones to whether they take the bait

Members from the SFEL have published a new study of stress responses in largemouth bass that found those that are less likely to strike at a fishing lure also tend to experience higher cortisol levels after a stressful encounter. Illinois Natural History Survey research scientist Dr. Jeffrey Stein and graduate student Michael Louison, along with Natural Resources and Environmental Sciences professor Cory Suski, found a relationship between fish stress responses and catchability. This is called fisheries-induced evolution, which occurs when humans capture fish with specific traits, leaving behind genetically distinct survivors. Read more about this study here.
