Trends in US recreational catch and effort data for Atlantic blue marlin and white marlin from 1972 to 2000 are examined. A method for predicting and setting minimum size regulations for this fishery is described. Additionally, this paper re-examines the impact of the most recent minimum size increases on the US recreational fishery for Atlantic marlin. The effectiveness of setting minimum size limits as a primary management approach is discussed, as is the increase in catch and release fishing in the US recreational marlin fishery.

Abstract Weltersbach, M. S., and Strehlow, H. V. 2013. Dead or alive—estimating post-release mortality of Atlantic cod in the recreational fishery. – ICES Journal of Marine Science, 70: 864–872. Atlantic cod (Gadus morhua) is one of the most important commercial and recreational target species in European marine waters. Recent recreational fisheries surveys revealed that recreational cod catches and release rates are substantial compared to the commercial fishery, particularly in the western Baltic Sea. Despite high release rates, no literature exists exploring the post-release mortality of cod and potential sublethal effects after catch-and-release in recreational fisheries. This study investigates (i) the post-release mortality of undersized cod, (ii) potential factors affecting mortality, and (iii) consequences of the catch-and-release process on cod. During four experimental trials, western Baltic Sea cod were angled from a charter vessel and thereafter observed together with control fish in netpens for 10 d at holding temperatures between 6.2 and 19.8°C. Adjusted mortality rates for angled cod ranged from 0.0–27.3% (overall mean 11.2%). A logistic regression analysis revealed that bleeding and holding-water temperature were the only significant predictors of mortality. Slow hook injury healing (>10 d) and bacterial wound infections were observed in some surviving cod. The results will help to increase the accuracy of recreational cod removal estimates and thereby improve the management of western Baltic cod stock.

Fisheries are complex social–ecological systems with multiple potential linkages between fish and anglers. Understanding these linkages helps to support effective fisheries management. We examine the social–ecological dynamics of a recreational fishery by assessing relationships between fish, anglers, and a management intervention. We focus on catch-and-release steelhead trout (Oncorhynchus mykiss) fisheries on six rivers within the Skeena River watershed, British Columbia, Canada, the location of a recent management intervention. First, based on analyses of annual steelhead trout abundance and annual angler effort information, we found that years with a higher abundance of returning steelhead trout were associated with years of higher catch rates and angler effort. Second, based on analyses of nonresident angler effort, we discovered that a new management intervention provided periods of lower angler effort, but effort was apparently redistributed to other rivers and time periods. Third, responses from angler interviews post-management intervention revealed that anglers were more satisfied if they caught more fish and experienced less crowding; at higher crowding levels, higher catch rates were required to increase angler satisfaction. In conclusion, we found that this recreational fishery is influenced by both human dimensions and natural ecological dynamics such as fish population fluctuations.

Catch Composition

This study analyzed the profile of recreational fishers on-site in Ilhéus, northeastern Brazil, their fishing habits, and catch composition. Interviews were conducted along the coast of Ilhéus from December 2006 to December 2008 with all fishers encountered and their catch identified and measured. A total of 227 fishers were interviewed in 23 days. Most of the interviewees were men (93.4%), residing in Ilhéus (84.9%). They preferred fishing in the morning, weekends, and summer. Shrimp was the main bait used. Fishers were generalists, but most of the catch included Polydactylus virginicus, Ariidae, and Menticirrhus littoralis. Catches observed during the interviews allowed to estimate an annual catch of 1.4 t. A proportion of 88% of fishers practiced catch-and-release, mainly small fishes. Only 10.0% of them carried license for recreational fishing and about 5.3% were members of fishing clubs. This provides a unique opportunity to compare our results with those from another study conducted in the same locality during the same period with members of fishing clubs. These fishers used very small hooks during competitive events, which resulted in the capture of smaller fishes than was reported here on-site. This study sets a baseline to analyze temporal changes in fishing habits and catch.

Based on statistical data collected on the Varzuga River in 1991-2020, the results of recreational fishery of the Atlantic salmon on the basis of “catch and withdraw” and “catch and release” principle are considered. The paper identifies the issues concerning the calculation of quotas, the catch data reliability and the absence of the concept of returning the harvested aquatic biological resources to their habitat in the fishing legislation. Measures for the solution of these issues are proposed.

Improve Service Delivery

Educational audiologists often must delegate certain tasks to other educational personnel who function as support personnel and need training in order to perform assigned tasks. Support personnel are people who, after appropriate training, perform tasks that are prescribed, directed, and supervised by a professional such as a certified and licensed audiologist. The training of support personnel to perform tasks that are typically performed by those in other disciplines is calledmultiskilling. This article discusses multiskilling and the use of support personnel in educational audiology in reference to the following principles: guidelines, models of multiskilling, components of successful multiskilling, and "dos and don’ts" for multiskilling. These principles are illustrated through the use of multiskilling in the establishment of a hearing aid monitoring program. Successful multiskilling and the use of support personnel by educational audiologists can improve service delivery to school-age children with hearing loss.
