The role and worth of science in shark conservation advocacy
Where do environmental advocates get their scientific data?
Two-thirds of respondents indicated that they on a regular basis go through several peer-reviewed primary scientific literature content every single thirty day period, and only eight per cent of respondents indicated that they had in no way browse a peer-reviewed primary literature article. All respondents who described owning under no circumstances go through the literature worked for a non-gain with much less than 10 personnel. Fifty-5 per cent of respondents indicated that they had been a coauthor or guide author on at least just one peer-reviewed principal scientific literature article.
Fifty-6 % of respondents claimed that scientists were being immediately used by their non-gain, and 16% documented that their non-gain experienced a official scientific advisory board composed of unbiased scientists who were being available for technical session. Only 12% of respondents indicated that their NGO did not function with any researchers in any capacity (every of the 8% of respondents who claimed hardly ever acquiring browse a scientific article also claimed in no way doing work with researchers in any capacity). Of the respondents who did not get the job done with scientists in any capacity, 75% claimed doing work for very smaller (significantly less than 5 employees) shark-centered NGOs in Europe and North The usa.
Respondents claimed that science-primarily based arguments were by far the most frequently state-of-the-art arguments for shark conservation applied by their NGO (Fig. 2, Supplementary Supplies Desk S3), specially the notion that shark populace declines can result in destructive ecosystem-huge effects. Respondents described that moral or values-based arguments have been a lot fewer regularly used than science-primarily based arguments.

Does all appropriate scientific information access environmental advocates?
Surveyed environmental advocates had been most aware of scientific papers exhibiting extreme shark population declines and papers showing damaging ecological implications of those people declines (97% and 100% recognition respectively). Though rebuttals to those people papers (72.7% recognition) and papers showing that that sustainable shark fisheries are attainable (82.6% recognition) were being however extensively identified, they experienced lower consciousness amid respondents in contrast with papers showing populace declines and ecological outcomes of those declines. Some extensively-publicized papers about shark conservation have been considered rather controversial by other researchers in the subject resulting in rebuttals. Rebuttals can be observed as an attempt to proper the scientific record by pointing out an mistake in the first paper, hence awareness of the rebuttals was considered to be a proxy for technological expertise associated to the current point out of scientific evidence of shark conservation and administration challenges.
In abide by-up interviews, respondents documented actively seeking for rebuttals every time they discovered a paper that appeared to support their perspective. Just one spelled out “We appear for it all, and we’re always open up to making use of new science that will come alongside and tells us a thing distinctive.” A different explained, “We often consider and involve rebuttals and contradictory info to give the whole picture.” A 3rd instructed interviewers that “It is too effortless to see a paper that justifies your assert that you can soar on and use, but how valid is that?” Interviewees regularly stressed the relevance of in search of out information that not only supported their arguments but was scientifically legitimate.
Some of the environmental non-income advocates surveyed right here also elevated concerns about the focus of most shark research created by academic experts. A number of respondents suggested that exploration could be created a lot more beneficial by broadening the present concentrate (a couple effectively-analyzed species in a few very well-examined areas) to include things like significantly less charismatic species and much less-frequented examine websites, specifically individuals in the creating globe. Respondents also elevated issues about scientists professing to do conservation-related exploration with out consulting managers, regional colleagues, or users of the impacted group to see what type of info would be most handy. Just one comply with-up Skype interview participant explained that if experts want to do policy-related exploration, “The initial action is to try out and detect details demands of policymakers they know what they never know and what they need to have to know- converse to them as early as possible when commencing a study job!”.
Respondents also instructed new roles for experts, this sort of as serving as public educators or advocates for conservation by communicating their analysis to the public. Various respondents from the producing world recommended the experts from wealthy establishments or nations must cease engaging in “helicopter science” or “parachute science”18 by checking out faraway areas and leaving as before long as their analysis was accomplished (although this time period can also refer to exploitative relationships with geographically proximate indigenous communities, we notice that our respondents ended up apparent that they intended worldwide apps of this termInstead, respondents ask for that viewing scholars present instruction and chances to colleagues and college students in the building globe to acquire neighborhood capability. There have been also phone calls for more study on the human proportions of shark conservation, like socioeconomic reports of shark fishers.
Do environmental advocates operate towards the mentioned coverage preferences of scientist?
Over fifty percent (56%) respondents accurately determined that printed scientific proof displays that sustainable shark fisheries are attainable, and almost 50 percent (46%) correctly discovered that revealed scientific proof shows that sustainable shark fisheries exist in the entire world today (there is no factual or scientific doubt that these types of fisheries can and do exist though preferring bans based on individual values is a legitimate tactic, proclaiming that bans are universally vital due to the fact sustainable fisheries are scientifically unachievable is a misrepresentation of the science). A lot more than 3-quarters (78%) of respondents agreed with the assertion that the intention of shark conservation advocacy ought to be to promote sustainable exploitation in its place of full bans on exploitation and trade (Fig. 3, Supplementary Products Table S4). In just about every case, drastically much less NGO workers than earlier-surveyed AES experts agreed with these statements.
Proportion of environmental advocate respondents from this review (blue) and scientists respondents from Shiffman and Hammerschlag 2016B (eco-friendly) who concur with these three issues, with * indicating a important change in responses to every single issue in between the two groups making use of a 2-tailed Z exam of independent proportions (for Concern 1, Z = − 3.66, P = 0.0003, for Issue 2, Z = − 4.48, P < 0.00001, for Question 3, Z = − 1.87, P = 0.03).
Results show that in general, the environmental advocates who most strongly supported bans on fisheries and trade were the least familiar with the current state of scientific knowledge on sustainable shark fisheries. While many of these respondents reported that science was important to advocacy and that their arguments were based on science, many arguments misrepresented the state of the science. A conditional inference tree found that the primary partitioning variable associated with general support for bans on trade was self-reported regularity of reading the scientific literature 100% of respondents who report never reading the scientific literature (N = 4 of 4) supported bans over sustainable fisheries, compared with just 10.5% of respondents who reported regularly reading the scientific literature (N = 4 of 38), (Figs. 4, 5). There was also a clear geographic bias with respondents who worked in the developed world more likely to support bans than those working in the developing world (Fig. 4).
Proportion of environmental advocate respondents who agree with the statement that sustainable fisheries (as compared with bans on all fishing and trade) should be the goal of shark conservation, broken down by regularity of reading the literature, highest degree earned, and geographic area of focus.
Results of conditional inference trees for the questions “should the goal of shark conservation be sustainable fisheries or total bans on fisheries and trade,” “do you support shark fin trade bans,” and “do sustainable shark fisheries exist in the world today,” showing primary partitioning variables for each and the results of separating the data by those partitioning variables.
Of respondents who supported a total ban on all exploitation and trade over sustainable fisheries, 86% work in the US or Europe, while 100% of respondents who work in South America (N = 3), the Indo Pacific (N = 1), the Caribbean (N = 1), or Africa (N = 1) who answered this question preferred sustainable fishing over bans (Fig. 4). One-third (N = 7) of respondents who work at shark-specific environmental non-profits support bans over sustainable fisheries, compared to just 12% (N = 3) of those who work in ocean-focused environmental non-profits. Fifty percent of all stated preferences for bans over sustainable fisheries came from advocates working for very small (less than five employees) non-profits.
Respondents who did not agree that sustainable shark fisheries are possible or exist cited a variety of reasons, ranging from not having personally seen evidence of sustainability to technical concerns to a general overarching belief that sustainable fisheries in general cannot and do not exist (Table 1).
The individual who reported never having personally seen any evidence of sustainable shark fisheries also reported never having read the scientific literature and never interacting with professional scientists. Those respondents who did agree that sustainable shark fisheries are possible and exist mostly cited peer-reviewed published technical literature to support their opinion (Table 2), though several noted that while these fisheries can and do exist, there are not very many of them, and not all shark fisheries are potentially sustainable.
This suggests that while some advocates are not aware of the current state of science on this topic or are misinformed about it, for some, the issue is less about knowledge of whether sustainable shark fisheries are possible in theory than about whether they personally believed successful implementation of sustainable management practices was probable or practical in the complex real world—there are certainly many examples of poorly managed shark fisheries, a point broadly understood both by those advocating for improving fisheries sustainability and those advocating for bans.
One respondent explicitly mentioned misinformation from other non-profits as a possible cause of public misunderstanding on the issue of sustainable shark fisheries. A conditional inference tree indicated that the primary partitioning variable driving agreement with the statement that sustainable shark fisheries exist was awareness of rebuttals to high-profile shark conservation papers, which was used as a proxy for awareness of the current state of technical literature (Fig. 5). Only 24% of respondents who were unaware of those rebuttals agreed that sustainable shark fisheries exist, compared to 78% of those who were aware of these rebuttals. Of respondents who report regularly reading the scientific literature, 88.6% (N = 39) agree that there are current examples of sustainable shark fisheries, compared with just 50% (N = 2) of those who never read the literature and 62% (N = 10) of those who rarely read the literature. Sixty-five percent of all respondents who agree that sustainable fisheries do not exist come from the US or Europe, and no respondents in the Caribbean, South America, or Africa agreed with the statement that sustainable shark fisheries do not exist.
A plurality of respondents (45.8%) agreed with the statement that the science concerning the sustainability of shark fisheries is currently uncertain, and 15.2% of respondents agreed with the statement that the science is clear that sustainable shark fisheries cannot and do not exist. Sixty-five percent of respondents with a Masters or Ph.D. degree correctly identified that the science is clear that sustainable shark fisheries can and do exist (and 0 respondents with a Masters of Ph.D. degree indicated that the science is clear that sustainable shark fisheries cannot and do not exist). There was also a divide by familiarity with the scientific literature, none of the respondents who never read scientific papers correctly identified that the science is clear that sustainable shark fisheries can and do exist, compared with 26.6% of those who rarely read the literature and 45.2% of those who regularly read the literature. Fifty percent of respondents who never read the literature inaccurately reported that they agree that the science is clear that sustainable shark fisheries cannot and do not exist, compared with 26.6% of those who rarely read the literature and 9.5% of those who regularly read the literature. Nine percent of respondents reported that their opinions about shark fisheries come from their personal ethical values, and therefore scientific measures of sustainability are not relevant to their decision-making on this topic.
Fifty-four percent of respondents reported that their environmental non-profit organization has worked on fisheries management tools in the last five years, compared with lower numbers of those whose employer worked on no-take marine protected areas (45.2%), fin bans (25%), and Shark Sanctuaries (16.7%). Many respondents noted that different contexts (cultural, political, and economic) require different kinds of solutions, that there is no one “silver bullet” policy for shark conservation, and that enforcement of existing management rules is critical no matter which policy strategy is selected. Significantly more respondents support traditional fisheries management tools (73.3%) than support either Shark Sanctuaries (49.1%) or shark fin trade bans (41%), and significantly more respondents oppose Shark Sanctuaries (30.1%) and shark fin trade bans (32.7%) than oppose traditional fisheries management tools (5%) (Fig. 6). There was no difference in support for or opposition to no-take marine protected areas versus traditional fisheries management tools. The only respondent who strongly disagreed with traditional science-based fisheries management tools also reported never reading the literature or interacting with a scientist.
Proportion of respondents who support, oppose, or have no opinion concerning a variety of conservation policies. All target-based traditional fisheries management tools were grouped together because there were no differences in responses.
A conditional inference tree indicated that the primary partitioning variable associated with support for shark fin trade bans was agreement with the statement that sustainable shark fisheries cannot exist (Fig. 5) 100% of respondents who agree that sustainable shark fisheries cannot exist support shark fin trade bans, compared with 24% of respondents who agree that sustainable shark fisheries can exist. Respondents with a Ph.D. showed the least support for shark fin bans (18.1%, compared to 43.7% support from respondents with a Bachelor’s degree and 54.1% support from respondents with a Masters). Respondents who regularly read the literature had the lowest support for fin bans (31.5% support, compared with 57.1% support from those who rarely read the literature and 75% support from those who never read the literature) (Fig. 7). The only two geographic regions where more respondents supported fin bans than opposed them were Europe (56.2% support) and North America (60% support). In Asia, 50% of respondents opposed fin bans compared to 33.3% who support them. No respondents from the Caribbean supported fin bans. The Indo-Pacific and South America had equal numbers of supporters and opponents.
