Restorative function of offshore longline mussel farms with ecological benefits for commercial crustacean species.

Offshore ocean aquaculture is expanding globally to meet the growing demand for sustainable food production. At the United Kingdom's largest longline mussel farm, we assessed the potential for the farm to improve the habitat suitability for commercially important crustaceans. Modelled distribution patterns (GAM & GLM) predicted the low complexity seabed beneath the mussel farm was 34-94 % less suitable for European lobster (Homarus gammarus) and brown crab (Cancer pagurus) than nearby rocky reefs.

Combining acoustic telemetry with archival tagging to investigate the spatial dynamic of the understudied pollack, Pollachius pollachius.

Combining fish tracking methods is a promising way of leveraging the strengths of each approach while mitigating their individual weaknesses. Acoustic telemetry provides presence information as the fish move within receiver range, eliminating the need for tag recovery. Archival tags, on the other hand, record environmental variables on tag retrieval, enabling continuous path reconstruction of a fish beyond coastal regions.

A novel method for identifying coded tags recorded on aquatic acoustic monitoring systems.

Aquatic biotelemetry increasingly relies on using acoustic transmitters ('tags') that enable passive detection of tagged animals using fixed or mobile receivers. Both tracking methods are resource-limited, restricting the spatial area in which movements of highly mobile animals can be measured using proprietary detection systems. Transmissions from tags are recorded by underwater noise monitoring systems designed for other purposes, such as cetacean monitoring devices, which have been widely deployed in the marine environment; however, no tools currently exist to decode these detections, and thus valuable additional information on animal movements may be missed.

Before and after resident work hour limitations: an objective assessment of the well-being of surgical residents.

Purpose: To assess the impact of resident work hour limitations on how surgical residents feel about their training, patient care, and their overall well-being.

Methods: Three surveys were administered to 28 categorical surgery residents before and after implementation of the Accreditation Council on Graduate Medical Education (ACGME) work hour restrictions. The surveys consisted of a Beck Depression Inventory II (BDI-II), a SF-36 Health Status Profile (SF-36), and a custom 20-item Likert scale survey.
