Research is showing that use of best practices \u2014 notably, use of a descending device \u2014 help improve survival of released deep-water fishes. Make sure to have yours aboard and readily available starting this week.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Research Need<\/strong><\/h3>\n\n\n\n<p>Reducing mortality after catch-and-release in offshore recreational fisheries remains an important component of stock rebuilding for many reef fish. Mortality for these species can be high due, in part, to injury sustained during capture, coupled with high catch rates and regulations about release.<\/p>\n\n\n\n<p>Recent scientific studies have shown that fish descending devices are highly successful for minimizing trauma to reef fish by aiding in releasing them at depth. The devices perform better for increasing survival rates of many different species compared to venting, which involves use of a tool to expel gas that accumulates within fish when brought to the surface when caught.<\/p>\n\n\n\n<p>Until recently, however, attitudes within the recreational angling community about using descending devices have been relatively unknown.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What did they study?<\/strong><\/h3>\n\n\n\n<p>Scientists at the Center for Sportfish Science and Conservation, in partnership with the organization FishSmart, distributed over 1,000 fish descending devices to anglers from North Carolina to Texas and surveyed them about the use of these devices. After using the devices for an average of eight months and 15 fishing trips, recipients completed the survey.<\/p>\n\n\n\n<p>Questions of particular interest assessed what percentage of fish the anglers believed survive after release and to what extent anglers would use the device in the future.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What did they find?<\/strong><\/h3>\n\n\n\n<p>Anglers released over 7,000 red snapper and 4,000 other reef fish using their descending devices. Prior to receiving their device, 72% of respondents had little to no knowledge of descending devices, though 89% had used venting tools in the past.<\/p>\n\n\n\n<p>After using their device, 70% of respondents indicated that they preferred this method of release over venting, and 76% were likely to continue employing the device on their vessel. In addition, 89% believed that using descending devices would significantly reduce mortality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Anything else?<\/strong><\/h3>\n\n\n\n<p>Although overall preferences for using descending devices was high, responses from the head boat sector were underrepresented. Because many anglers catch fish simultaneously on head boats, the few responses from this sector may indicate it is less likely to use these devices, due to the time-consuming nature of the process (compared to venting) while also juggling multiple client demands. Further research and development of more efficient strategies to descend fish and about how such strategies can best work on head boat charters would be extremely useful moving forward.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>So what? <\/strong><\/h3>\n\n\n\n<p>These data provide managers with important information regarding the opinions of fishery stakeholders. Despite some variations in attitudes and feasibility, the majority of anglers are receptive to using descending devices, and they believe the devices could be beneficial in reducing the mortality of reef fish species. Anglers have confidence their discards will survive, potentially even for future recapture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reading<\/strong><\/h3>\n\n\n\n<p>Curtis, J.M., Tompkins, A.K., Loftus, A.J., and G.W.
