Does the library offer a book delivery service?
Yes, LSU Library offers book deliveries to faculty and staff only . We will deliver LSU Library books and interlibrary loan books to your departmental mailbox. Reserve and Government Document materials will not be included. To use the service, request the item through your interlibrary loan account. On the request form under "Delivery Options" select "Deliver to Departmental Mailbox." The request will arrive 1-2 business days from the date we receive the item. Heres how to get your materials delivered:
- You will need an ILLiad account to make the request.
- Once logged in, you will need to select "Deliver to Departmental Mailbox" for your Delivery Method. Books will be delivered to the departmental mailbox of the requestors within 1-2 business days. A second attempt will be made if the delivery is not successful the first time, but if the department office is inaccessible again, patrons will receive an e-mail stating the problem and asking them to come pick up their materials.
- The materials will be placed on hold and kept at the checkout desk for 7 days. If they are not picked up in this time frame, they will be returned to the collection. Be aware of the following:
- Users are responsible for returning materials back to the library.
- Materials will be checked out to the patrons library account prior to being delivered.
- The user is responsible for the items requested through this service.
- Any LSU Library books not returned or renewed within 40 days of the due date will be considered lost and the usual penalties will apply.
- A limit of eight physical material format items can be requested per day. LSU Libraries | Book Delivery Answered by: Access Services Staff

Ecological Aspects of Bottom Gill Nets Catches During the Evening and Pre-dawn Periods in Inner Ambon Bay, Indonesia.
Gill nets are widely used in small-scale fisheries because of their simplicity and efficiency, particularly for capturing demersal and pelagic species. This study analyzed the catch characteristics of bottom-set gill nets with a 5.08cm mesh size during the evening (7:00-8:30 PM) and pre-dawn (4:00-5:30 AM) periods in Inner Ambon Bay, Indonesia. A total of 30 fishing trips were conducted, and data on species composition, catch diversity, and length frequency distribution were collected. The results revealed significant temporal variation in species composition and dominance. In the evening, Selar crumenophthalmus was the most dominant species (64.57%), whereas its proportion decreased to 38.15% in the pre-dawn period, accompanied by an increase in Upeneus moluccensis (19.61%). Diversity indices (Shannon-Wiener) indicated moderate diversity, with higher values during the pre-dawn period (1.51) than during the evening (1.36). Dominance was lower in the pre-dawn period (0.09) than in the evening (0.44). Length frequency analysis showed that the gilled method was the most effective capture mechanism, selectively targeting fish in the 21.5-22.5cm range. These findings emphasize the influence of fishing time on catch composition and size selectivity, providing insights for optimizing fishing practices and supporting sustainable fishery management in Inner Ambon Bay.

Optimal harvest strategies with catch-dependent pricing for chub mackerel in South Korea.
Chub mackerel (Scomber japonicus) is a key commercial species in South Korea. However, the catch volume of chub mackerel has experienced significant fluctuations over the past few decades, with current trends indicating a decline. Despite regulatory measures such as closed seasons, resource depletion remains a concern, thereby highlighting the requirement for effective management strategies. Numerous previous studies have proposed optimal harvest strategies by assuming constant prices. However, as large catches of mackerel tend to have lower prices, it is crucial to develop optimal harvest strategies that account for this decrease. Thus, we aim to develop a monthly optimal harvest strategy for chub mackerel that considers catch-dependent pricing. We define logarithmic, rational, and irrational catch-dependent price functions and their corresponding objective functions. In addition, we develop an optimal control system based on a discrete age-structured model. We use Pontryagin's maximum principle to prove the necessary conditions for the optimal harvest strategy under the three catch-dependent pricing functions and perform simulations using the forward–backward sweep method. We compare the optimal harvest strategies under the three catch-dependent pricing scenarios with those under a constant price. The optimal harvest strategies with the rational and irrational price functions are similar to those with a constant price, where the fishing effort increases immediately after spawning and then gradually decreases. In contrast, the optimal harvest strategy with the logarithmic price function involves a gradual increase in fishing effort from July immediately after the spawning period, with the maximum effort in June before the next spawning season. In addition, we compare the effects of monthly closed seasons across the four pricing scenarios. A closed season in July immediately after spawning provides the highest resource recovery efficiency. In contrast, a closed season in June provides the highest catch and profit efficiencies. As the cost per unit of effort increases, the fishing effort, catch, and profit decrease, while the biomass increases, and the profit decrease is smallest under the logarithmic price function. Our method can improve monthly optimal harvest strategies for other species using catch-dependent pricing functions as well as significantly contribute to enhancing fishers' profit.
