Valuing Angling on Reservoirs Using Benefit Transfer

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two approaches to benefit transfer—value transfer and function transfer—which we demonstrate estimate similar economic values for fishing site access but substantially different economic values for catch rate improvements at some reservoirs. We encourage agencies that are responsible for inland recreational fisheries management to consider economic assessment, especially benefit transfer, as a critical tool in the management toolbox

Stepping Up: A U.S. Perspective on the Ten Steps to Responsible Inland Fisheries

The Ten Steps to Responsible Inland Fisheries are global recommendations to address the subordinate position of inland fisheries in sustainability dialogues. Regional and local perspectives are essential for implementing global initiatives. Hence, we surveyed state fisheries agency administrators and American Fisheries Society Governing Board members about the importance, funding, and achievability of the Steps. Respondents rated Science, Communication, and Assessment as highly important, well funded, and achievable steps, unlike Aquaculture and a global Action Plan. Nutrition was rated the most inadequately supported yet achievable step, highlighting an opportunity to promote nutritional contributions of inland fisheries. Opinions were similar between administrators and Governing Board members across U.S. regions, suggesting a foundation for incorporating underemphasized steps into management programs by building multi-organizational partnerships and applying lessons from better integrated steps (e.g., Science, Assessment). Overall, the Steps can advance freshwater science and management in the United States while increasing the visibility of inland fisheries that are rarely prioritized globally.This article is published as Carlson, Andrew K., William W.

Robotic total pancreatectomy with splenectomy: technique and outcomes

BACKGROUND:Robotic total pancreatectomy (TP) represents a minimally invasive approach to a major intra-abdominal operation. Its utility, technique, and outcomes are evolving. METHODS:In this video, we describe a systematic approach to a robotic total pancreatectomy performed for multifocal intraductal papillary mucinous neoplasm (IPMN). Additionally, we reviewed the National Cancer Database (NCDB) to examine the outcomes of robotic TP compared to laparoscopic and open TP between 2010 and 2014. RESULTS:The patient is a 61-year-old female who was diagnosed with multifocal IPMN. A total of 6 robotic ports were placed and the da Vinci Xi robotic system was used with the patient supine. The approach entailed as follows: (1) Diagnostic laparoscopy; (2) Entry into the lesser sac; (3) Division of the short gastric vessels; (4) Exposure and dissection of the inferior pancreas border; (5) Dissection and transection of the splenic artery; (6) Mobilization of the pancreas tail/spleen; (7) Exposure of the splenic vein-superior mesenteric vein confluence; (8) Kocher maneuver; (9) Release of the ligament of Treitz and transection of the proximal jejunum; (10) Transection of the distal stomach; (11) Portal lymphadenectomy; (12) Dissection and transection of the gastroduodenal artery; (13) Superior mesenteric vein exposure/dissection of the uncinate process; (14) Hepaticojejunostomy; (15) Cholecystectomy; and (16) Gastrojejunostomy. NCDB database review of 73 patients who underwent robotic TP revealed similar rates of margin negative resections and retrieved lymph nodes between robotic, laparoscopic, and open TP, whereas robotic and laparoscopic TP were associated with shorter in-hospital stay and reduced mortality at 30 and 90 days compared to open TP. Overall median survival of pancreatic adenocarcinoma patients who underwent TP was similar between robotic, laparoscopic, and open approaches. CONCLUSION:Robotic total pancreatectomy with splenectomy offers a minimally invasive approach to a major abdominal operation and is feasible in a stepwise, reproducible technique. It is associated with improved postoperative outcomes and equivalent oncologic outcomes compared to open TP
