Why does my library account say that I am blocked, that I am barred, or that my status is expired?
Users can encounter several different types of status messages. Patrons with questions about their account status can visit the checkout desk in room 241 of LSU Library and ask to speak to a staff member. Alternatively, patrons can reach out to us via e-mail at libcirc@lsu.edu (mailto:libcirc@lsu.edu) . When contacting us via e-mail, LSU students, staff, and faculty should message us from their LSU e-mail address; public patrons should message us from the e-mail address we have on file. For privacy reasons, we cannot discuss the details of patron accounts over the telephone. Expired: Students must be currently enrolled in classes in order to be granted library privileges. Once they graduate, or if they fail to register on time in accord with the deadlines posted on LSUs academic calendar, their privileges expire. If they try to log in to their library account after that date, they will see an alert message informing them that their account has expired. Graduate students who have received a masters degree but are continuing on to get their PhD may also have their privileges expire earlier than expected. The library receives weekly updates on student status from the Registrars Office. Once the semester has begun, if students register during the week, their accounts will not be updated and their privileges extended in the system until the following Monday morning. Blocked: Users with overdue recalled books will have their accounts blocked by the system. Their accounts will remain blocked until the book is returned. The system will not permit staff members to override blocks or to renew books that have been recalled. The only way to remove a block from an account is to return the materials. Barred: Users can be barred from using library materials for a number of reasons, the most common being that they have been billed for lost items. They can also be barred if they resign from the university, if their classes are purged, or for flagrant violations of library policy. If they try to log into their account after they have been barred, they will receive an alert message that tells them that they have been barred. Answered by: Access Services Staff

Domestication as the driver of lower chronic stress levels in fish in catch-and-release recreational fisheries and aquaculture versus wild conspecifics.
The manipulation of species' attributes through selective breeding can produce domesticated traits including decreased stress responses (i.e., selecting for high stress resilience). Common carp Cyprinus carpio ("carp") have been domesticated for centuries, with domesticated forms frequently used to enhance recreational catch-and-release fisheries around the world. In Atlantic salmon Salmo salar ("salmon"), two primary strains are evident, a wild strain and domesticated aquaculture strain. Here, we compared scale cortisol concentrations (a biomarker of fish chronic stress levels) between domesticated carp in catch-and-release pond fisheries and wild carp in waters with no angling. Carp of low scale cortisol concentration were apparent in all sampled populations, suggesting individuals of low stress sensitivity are encountered in both wild and domesticated strains, and in natural and captive environments. Carp with relatively high levels of scale cortisol were, however, only present in wild carp, suggesting high phenotypic variability in their chronic stress responses, with some individuals being highly sensitive to stress. In some wild carp, elevated scale cortisol concentrations could also have been indicative of adaptive responses to their heterogenous environments. We then compared wild versus farmed salmon scale cortisol levels, and found a similar pattern, with relatively high scale cortisol levels only detected in wild fish. These results indicate that while domesticated carp and salmon are exposed to potentially stressful environments, they appear to have some resilience against the adverse effects of chronic stress.

Catch-And-Release Fishing: A Case Study in Poland.
The purpose of this study is to determine the current state of angler knowledge, opinions, awareness, and use of catch-and-release (C&R) best practices and to identify the main socio-economic factors that determine attitudes and willingness to use C&R among Polish anglers. Knowledge of this issue contributes to more effective management of fisheries and fish stocks. The research was conducted through an online survey form using a technique called CAWI (Computer-Assisted Web Interview). The questionnaire used consisted of 25 questions, including basic socio-economic questions, questions about seniority, frequency, location and method of fishing, and specific factual questions related to knowledge and practices regarding C&R. A total of 1574 respondents participated in the survey. The majority of respondents were male (97.5%). The survey showed that Polish anglers are overwhelmingly willing to practice C&R: 48.8% of respondents always and 44.0% often voluntarily release the fish they catch. Statistical analysis revealed a significant relationship between the use of this practice and the age of the angler (r = 0.46; p = 0.0001). Anglers under the age of 55 were the most likely to use C&R (p = 0.0097). The majority of respondents believe that C&R is important for improving fish stocks, but their knowledge and practices in this area have serious shortcomings. Inadequate knowledge of issues such as barotrauma or safe hook types, as well as inappropriate practices such as photographing and unhooking fish, can negatively affect their survival and ultimately the status of living water resources and ecosystem quality. These shortcomings may be due to inadequate education of anglers and fishery managers. [ABSTRACT FROM AUTHOR]
