Why Fishermen Keep Fishing Despite Dwindling Catches
Half of fishermen will not give up their livelihood in the face of drastically declining catches according to research led by the University of East Anglia (UEA).
A new report, published Feb. 6 by PLoS ONE, challenges previously held notions about poverty and adaptation by investigating why fishermen in developing countries stick with their trade.
“We found that half of fishermen questioned would not be tempted to seek out a new livelihood—even if their catch declined by 50 percent," said Dr. Tim Daw, lead author from UEA’s School of International Development. "But the reasons they cling on to their jobs are influenced by much more than simple profitability.”
Fisheries are challenged by the combined effects of overfishing, climate change, deteriorating ecosystems and conservation policies. Understanding how fishermen respond to these changes is critical to managing fisheries.
The research project is the largest of its kind and was undertaken as a joint project with the Wildlife Conservation Society, the School of Marine Science and Technology at Newcastle University, and the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia.
Researchers surveyed almost 600 fishers across Kenya, Tanzania, the Seychelles, Mauritius and Madagascar about how they would respond to hypothetical catch declines.
They then investigated how social and economic conditions, such as local culture and socioeconomic development, influenced whether fishermen were willing to give up their trade.
“Surprisingly, fishermen in the more vibrant and developed economies were less likely to give up their trade—despite having more economically fruitful opportunities open to them,” said co-author Dr. Joshua Cinner from the ARC Centre of Excellence for coral reef Studies in Australia.
“This is the reverse of the common belief that poor communities are less likely to adapt than wealthy ones. We suspect that this may be in part due to the perverse impacts of subsidies in more developed countries encouraging people to stay in the fishery even when it is not profitable.”
“But reduced profitability was certainly not the only deciding factor," said Dr. Daw. "Fishers often have an occupational attachment, job satisfaction, family tradition, culture, and a sense of identity, which makes them reluctant to stop fishing—even when it would be an economically rational decision.”
The research demonstrates the complexity of decision making and how willingness to adapt is influenced by a range of factors.
“We have found that willingness to adapt to change is influenced by cultural, as well as economic, factors—with differing scales of importance,” said Dr. Daw. “Undertaking such a large-scale analysis has helped to untangle the complexity of the situation."
“Previous studies have been too small to offer insights into larger scale factors," Dr. Daw continued. "This is the first large-scale study to evaluate the willingness of fishers to exchange their livelihoods for a new trade—and how this decision is influenced by factors operating at different scales,” he added.
“This is very important research which helps us understand why and when fishers will leave a fishery," said Tim McClanahan from the Wildlife Conservation Society. “Some of the findings are unexpected and contrary to many arguments about the impacts of management and climate change on poor people. They will be a surprise to many people working in this field and the policies associated with resource and disaster management.
“A surprising finding was that fishermen in a poor country like Madagascar would leave the fishery sooner than those in wealthy countries such as the Seychelles. This indicates that the poor do have alternatives to fishing and lower investments that allow them flexibility in the face of environmental and management changes.
“So, the poor can adapt to climate change and temporary losses in fishing grounds as long as the alternatives are productive, which helps when trying planning for improvements in fisheries management in poor countries," added McClanahan.
The findings add to a growing raft of literature which identifies multiple interlocking and dynamic factors which affect people’s capacity to deal with environmental change. It is hoped they will help identify points of intervention for conservation policies that aim to reduce fishing effort. They could also help communities become more adaptive to change.
It also highlights the importance of understanding resource-based livelihoods, such as fishing and farming, in the context of the wider economy and society.

One of nature's epic events is underway: Monarch butterflies' fall migration. Departing from all across the United States and Canada, the butterflies travel up to 2,500 miles to cluster at the same locations in Mexico or along the Pacific Coast where their great-grandparents spent the previous winter.
Millions of People Care About Monarchs<p>I will never forget the sights and sounds the first time I visited monarchs' overwintering sites in Mexico. Our guide pointed in the distance to what looked like hanging branches covered with dead leaves. But then I saw the leaves flash orange every so often, revealing what were actually thousands of tightly packed butterflies. The monarchs made their most striking sounds in the Sun, when they burst from the trees in massive fluttering plumes or landed on the ground in the tussle of mating.</p><p>Decades of educational outreach by teachers, researchers and hobbyists has cultivated a generation of monarch admirers who want to help preserve this phenomenon. This global network has helped restore not only monarchs' summer breeding habitat by planting milkweed, but also general pollinator habitat by planting nectaring flowers across North America.</p><p>Scientists have calculated that restoring the monarch population to a stable level of about 120 million butterflies will require <a href="https://doi.org/10.1111/icad.12198" target="_blank">planting 1.6 billion new milkweed stems</a>. And they need them fast. This is too large a target to achieve through grassroots efforts alone. A <a href="https://www.fws.gov/savethemonarch/CCAA.html" target="_blank" rel="noopener noreferrer">new plan</a>, announced in the spring of 2020, is designed to help fill the gap.</p>
Pros and Cons of Regulation<p>The top-down strategy for saving monarchs gained energy in 2014, when the U.S. Fish and Wildlife Service <a href="https://www.fws.gov/southeast/pdf/petition/monarch.pdf" target="_blank">proposed</a> listing them as threatened under the Endangered Species Act. A decision is expected in December 2020.</p><p>Listing a species as endangered or threatened <a href="https://www.fws.gov/endangered/esa-library/pdf/listing.pdf" target="_blank">triggers restrictions</a> on "taking" (hunting, collecting or killing), transporting or selling it, and on activities that negatively affect its habitat. Listing monarchs would impose restrictions on landowners in areas where monarchs are found, over vast swaths of land in the U.S.</p><p>In my opinion, this is not a reason to avoid a listing. However, a "threatened" listing might inadvertently threaten one of the best conservation tools that we have: public education.</p><p>It would severely restrict common practices, such as rearing monarchs in classrooms and back yards, as well as scientific research. Anyone who wants to take monarchs and milkweed for these purposes would have to apply for special permits. But these efforts have had a multigenerational educational impact, and they should be protected. Few public campaigns have been more successful at raising awareness of conservation issues.</p>

The Rescue Attempt<p>To preempt the need for this kind of regulation, the U.S. Fish and Wildlife Service approved a <a href="https://www.fws.gov/savethemonarch/pdfs/Monarch%20CCAA-CCA%20Public%20Comment%20Documents/Monarch-Nationwide_CCAA-CCA_Draft.pdf" target="_blank">Nationwide Candidate Conservation Agreement for Monarch Butterflies</a>. Under this plan, "rights-of-way" landowners – energy and transportation companies and private owners – commit to restoring and creating millions of acres of pollinator habitat that have been decimated by land development and herbicide use in the past half-century.</p><p>The agreement was spearheaded by the <a href="http://rightofway.erc.uic.edu/" target="_blank">Rights-of-Way Habitat Working Group</a>, a collaboration between the University of Illinois Chicago's <a href="https://erc.uic.edu/" target="_blank" rel="noopener noreferrer">Energy Resources Center</a>, the Fish and Wildlife Service and over 40 organizations from the energy and transportation sectors. These sectors control "rights-of-way" corridors such as lands near power lines, oil pipelines, railroad tracks and interstates, all valuable to monarch habitat restoration.</p><p>Under the plan, partners voluntarily agree to commit a percentage of their land to host protected monarch habitat. In exchange, general operations on their land that might directly harm monarchs or destroy milkweed will not be subject to the enhanced regulation of the Endangered Species Act – protection that would last for 25 years if monarchs are listed as threatened. The agreement is expected to create up to 2.3 million acres of new protected habitat, which ideally would avoid the need for a "threatened" listing.</p>
A Model for Collaboration<p>This agreement could be one of the few specific interventions that is big enough to allow researchers to quantify its impact on the size of the monarch population. Even if the agreement produces only 20% of its 2.3 million acre goal, this would still yield nearly half a million acres of new protected habitat. This would provide a powerful test of the role of declining breeding and nectaring habitat compared to other challenges to monarchs, such as climate change or pollution.</p><p>Scientists hope that data from this agreement will be made publicly available, like projects in the <a href="https://www.fws.gov/savethemonarch/MCD.html" target="_blank">Monarch Conservation Database</a>, which has tracked smaller on-the-ground conservation efforts since 2014. With this information we can continue to develop powerful new models with better accuracy for determining how different habitat factors, such as the number of milkweed stems or nectaring flowers on a landscape scale, affect the monarch population.</p><p>North America's monarch butterfly migration is one of the most awe-inspiring feats in the natural world. If this rescue plan succeeds, it could become a model for bridging different interests to achieve a common conservation goal.</p>
The annual Ig Nobel prizes were awarded Thursday by the science humor magazine Annals of Improbable Research for scientific experiments that seem somewhat absurd, but are also thought-provoking. This was the 30th year the awards have been presented, but the first time they were not presented at Harvard University. Instead, they were delivered in a 75-minute pre-recorded ceremony.
