Achieving 30×30 by addressing how we fish
Created in partnership with
Wild Salmon Center
Sustainable fishing is the implementation of fishing practices that ensure healthy streams, rivers, lakes, and oceans, as well as healthy and diverse fish and wildlife populations long into the future.
This includes sustainable aquaculture, well-managed fisheries, and adapting human behaviors to respect and support balanced aquatic ecosystems.
“For [migrating] species like salmon—whose lifecycles span both marine and inland environments—the protection of upriver habitat and sustainable fishing are both crucial to their success… And, in turn, leads to healthier forests, robust food webs, and cleaner, colder water.”
– Kim Kosa, Wild Salmon Center
For tens of thousands of years, humans have sustainably harvested fish for both food and commerce. Examples of Indigenous Peoples in the northern Pacific Rim harvesting salmon for sustenance date back more than 10,000 years. To this day, Indigenous communities fish with intentionality, using fish and resource management practices to balance human needs alongside healthy fish populations and ecosystems.1“Indigenous Systems of Management for Culturally and Ecologically Resilient Pacific Salmon Fisheries,” Bioscience ≫
Unfortunately, the rise of industrial commercial fishing pushed aside these traditional practices until sustainable fishing became the outlier, not the norm. As we navigate toward a future that once again prioritizes sustainable fishing, we must acknowledge the originators and keepers of this traditional knowledge and uplift Indigenous communities as subject experts and leaders.2“Indigenous Fishing Practices Hold Promise for Future,” Wild Salmon Center ≫

Healthy fresh and marine waters require thriving fish populations to maintain balanced ecosystems. Why are balanced, aquatic ecosystems important? For starters, many countries and cultures around the world rely heavily on fish for both sustenance and income. It’s estimated that humans catch or consume 200 million tons of fish every year, equal to a total number of fish somewhere in the trillions. Fish, both freshwater and marine, are integral to food security worldwide, which makes protecting fish populations and their ecosystems even more important.3“Fish and Overfishing,” Our World in Data ≫; “Two-Thirds of the World’s Seafood Is Over-Fished,” Forbes ≫
Sustainable Fishing and Climate Change
Our planet’s waters are a huge carbon sink. Oceans alone absorb more than 30% of all human-produced carbon and roughly 90% of the heat created by these emissions. Rivers, streams, and lakes are also major carbon holders. So much so that, due to human activity and the destruction of forests and other carbon-holding environments, lakes have tripled the amount of carbon they bury in the sediment beneath them.4“Quantifying the Ocean Carbon Sink,” NOAA ≫; “The ocean – the world’s greatest ally against climate change,” United Nations ≫; “New study finds lakes have tripled the amount of carbon they bury,” Loughborough University ≫
The increased carbon level in our waters, as well as increasing water temperatures due to climate change—a result of excess heat absorption and human interference in natural habitats (e.g., dams, logging, and overfishing)—are wreaking havoc on ecosystems worldwide. Changing water temperatures dramatically impact fish reproduction and spawning grounds, and increased carbon levels in the water result in acidification, harming many aquatic species.
Learn about the who, where, and when of how we can leverage sustainable fishing for 30×30 goals.
Who has the power to initiate the greatest change when it comes to fishing and fisheries? Like with any environmental solution, there are many factors at play. However, to successfully address this question, we need to consider who has the power to make the greatest sweeping changes in policy, funding, and fishing industry practices.
Here are the groups that can help the most:

More than 70% of our planet is covered in water, which means there are a lot of places where we could focus our efforts on sustainable fishing. Certainly, an overwhelming prospect, but one that can be tackled by prioritizing those areas where human influence is most significant as well as important ecological regions where improvements to fishing practices will promote faster recovery.
EXISTING FISHERIES | It may not seem like fisheries and land conservation have much to do with one another, but this could not be further from the truth. Addressing how we protect and manage our existing wild fisheries can have beneficial outcomes for fish populations, other wildlife, food supply, and even our lands and forests. Initiating protections against harmful practices, such as mining and industrialization near important fish habitats, as well as introducing and actively managing for improved standards in sustainable fishing will play a large role in protecting the health and wellbeing of critical fresh and marine waters while simultaneously increasing livelihood prospects for fishers. Migrating salmon also fertilize trees and help with forest growth!5“Can shrimp farming restore mangroves?” Conservation International ≫; “Bristol Bay,” Wild Salmon Center ≫; “Effects of Salmon-Derived Nitrogen on Riparian Forest Growth and Implications for Stream Productivity,” Ecology ≫
FRESHWATER ECOSYSTEMS | Roughly 40% of fish caught for human consumption come from bodies of freshwater. When you consider the fact that freshwater only covers about 0.3% of the Earth’s surface, that forty percent begins to look a lot bigger.6“Sustainable Fishing,” National Geographic ≫
In tandem with other harmful drivers of global declines in freshwater biodiversity such as dams and other human-made industrial changes to watershed regions, it probably won’t come as a surprise that nearly one-third of all freshwater fish species are under the threat of extinction. Increasing freshwater fish populations isn’t just an ecological need either, it’s also a cultural one. Fish have been an integral part of human life for millennia. Addressing the health and wellness of our freshwater ecosystems is a critical step for the environment and for people to thrive.7“One-third of freshwater fish face extinction and other freshwater fish facts,” World Wildlife Fund ≫; “Early Humans May Have Cooked Fish 780,000 Years Ago,” Smithsonian Magazine ≫
NO-TAKE ZONES | A No-Take Zone is a stricter form of a marine protected area that, as the name suggests, disallows the fishing or procurement of sea life. These restrictions can be implemented at the local, territorial, tribal, state, and federal levels and can be strategically used in geographical areas that are ecologically important for species that are suffering. These protected areas can provide increased fishing opportunities in surrounding areas by protecting abundant, large, breeding-age individuals. Additional protections have been established in breeding grounds and nurseries and migration route waypoints. Qualifying freshwater habitats can also be given MPA status.8“Assessing spillover from marine protected areas and its drivers,” Di Lorenzo, Guidetti, Di Franco, Calò, Claudet; Fish and Fisheries, 2020 Sept. 21(5):906-15.
The good news is that sustainable fishing practices have been and continue to be used in many places around the world. In fact, many traditional techniques original to Indigenous communities (and still deployed for supporting everyday life) are now common practice for artisanal fishing, which employs 90% of the capture fisheries workforce worldwide (though this share is much smaller in North America). However, to have the positive impact needed, these practices need to be adopted on a broader scale and at a more rapid rate. Challenging, sure, but not impossible.9“Sustainable salmon fishing the Lummi way,” Seattle Times ≫; “Supporting Small-Scale Fisheries,” Sustainable Fisheries Partnership ≫
A 2016 report published in the Proceedings of the National Academy of Sciences estimates that, with proper reforms and management, global fish stocks can be at healthy levels again in just 10 years’ time AND will increase profits for fishers by 204% in the next three decades. Positive change is possible if we start now.10“Global fishery prospects under contrasting management regimes,” Proceedings of the National Academy of Sciences ≫

EVERYONE can help expand sustainable fishing practices, and strong public support is one of the fastest ways to set change in motion.

Education is the first step in building public support for sustainable fishing and fisheries. Humans catch around 200 million tons of fish every year, which means the total number of individual fish we’re catching likely amounts to a number in the trillions.
Without protections and sustainable management practices in place, we will deplete our oceans of this important food source for billions of humans—it’s just a matter of when. Unfortunately, there is a popular misconception among the public that, despite these statistics proving otherwise, we can’t possibly overfish our seas. To communicate the importance of sustainable fishing, we must first break through this false narrative, and that’s where education comes into play.
The more people know about the harmful effects of many of today’s most common fishing practices and the true reality of today’s declining ocean stocks and habitats, the better equipped they are to make educated decisions on where they purchase their seafood and from whom. Education also needs to be happening at the legislative level. Lawmakers with the power to support new and existing legislation should have a firm grasp of these basic concepts.

Dear Congressperson [NAME],
As a citizen of [YOUR STATE] and one of your constituents, I urge you to support the passing of [BILL NUMBER & NAME].
Sustainable fisheries are paramount to achieving food security and maintaining healthy habitats that can meet the demands of a growing global population. Not to mention, our oceans store about 30% of all human-produced carbon dioxide and 90% of the resulting heat. When habitats—including marine habitats—are healthy, they can store even more carbon. This benefits the health and well-being of all people, including [STATE] communities.
I strongly support this piece of legislation that prioritizes the health and sustainability of our fisheries, our communities, and our planet. I ask that you do the same and use your influence to advance this bill to a vote in the [HOUSE / SENATE].
Please let me know what action you intend to take on this bill. I appreciate your consideration and look forward to hearing from you.
Sincerely,
[YOUR NAME]
Hello, my name is [YOUR NAME] and I am a constituent of [CONGRESSPERSON’S NAME]. I am calling in support of [BILL NUMBER & NAME] and would like to leave a comment.
Legislative Staff Person will offer to transfer you to an answering machine or take down your message. Use the following to leave your message:
Hello, my name is [YOUR NAME] and I live in [YOUR CITY, STATE]. I am calling in support of [BILL NUMBER & NAME] and to communicate the importance of sustainable fisheries. Sustainable fishing and fisheries are paramount to achieving food security and maintaining healthy habitats that can meet the hunger demands of a growing global population. Not to mention, our oceans store about 30% of all human-produced carbon dioxide and 90% of the resulting atmospheric heat. When habitats—including marine habitats—are healthy, they can store even more carbon. This benefits the health and well-being of all people, including [STATE] communities.
As my representative in the [HOUSE / SENATE], I hope I can count on you to support [BILL NUMBER] and the development of more sustainable fisheries. It’s essential if we want a healthy future for the next generation of Americans.
Legislative Staff Person will ask if you want a response. You can politely decline, or say:
Yes. Please have a response sent to my email at [YOUR EMAIL ADDRESS] or by phone at [YOUR PHONE NUMBER]. Thank you for your assistance. Goodbye.

Our waters are significantly overfished. In the last fifty years alone, the number of overfished stocks around the world has tripled, leaving one-third of all global fish stocks overfished. This leaves fisheries, and those communities who rely on seafood as a primary food source, at high risk for climate-related tragedies such as natural disasters and warming waters, which can make seafood and fish capture scarcer. To help remedy this risk, fisheries need to be more sustainable and resilient to our changing climate by making marked improvements to their current practices.1“Plenty of Fish?” U.N. Framework Convention on Climate Change ≫
By using science to determine the best methods of fishing which allow stocks to regenerate naturally, and by reducing fisheries’ environmental influence by transitioning to clean energy and eliminating plastic usage, fishers and fisheries around the world have a much better chance of addressing food demand and doing so in a way that not only makes a greater profit, but which reduces environmental impact overall.
A marine protected area (MPA for short) is a nationally and/or internationally recognized geographical area of protected waters for the purpose of conservation. The purpose of an MPA is to place limits on human activity within that area—whether that’s fishing, boating, or even swimming—to reduce the harm done to essential marine ecosystems. National and state parks, as well as marine sanctuaries, are examples of MPA programs. And while having protected marine waters is certainly important, it can only be successful when these MPAs are properly managed and have consistent oversight and rule enforcement; something that many MPAs are missing today.2“Marine Protected Areas,” Protected Planet ≫
A capture fishery is one in which fish and other seafood are harvested (a.k.a. “fished” or “captured”) from the wild.
This can happen in both marine or freshwaters and can also include other naturally occurring organisms, like seaweed, which are also collected for human use and consumption.
How we spend our money matters, and that includes where and from whom we’re buying our seafood. Informed consumers are those who know where their food is coming from. How can you get started? Purchasing fish certified by the Marine Stewardship Council (MSC)—look for the blue logo—is one way buyers can be sure they are supporting sustainably sourced seafood. Likewise, check with your favorite local restaurants to see how they’re sourcing the seafood they serve.
When you quite literally put your money where your mouth is—even if you start small with one or two sustainable swaps a week—it can make a difference. Change adds up!
However, to make a significant change, this is a widespread shift that needs to be supported by consumers at large, so it’s critical that everyone reading this makes a concerted effort to make sustainable swaps and purchases whenever and wherever possible.
Forty-four percent of the global population lives within 93 miles of the ocean. These coastal and fishing communities are at the frontlines of both environmental harms and the positive changes that stem from activating sustainable solutions. As a result, they are in a unique and powerful position to not only implement change but be the voice for what changes are truly working.3“Doubling Ocean Protection,” Conservation International ≫
Community education and partnerships with environmental science and restoration groups will help build a foundation that sets these local communities up for success. How can this be achieved? By partnering with organizations that specialize in sustainable fishing and management and developing workshops, a network of consultants, as well as local, regional, national, and international networking support for independent fishers who may not have the funding and capacity to otherwise connect with other fishers and learn about sustainable practices.4“Coastal Fisheries Initiative: Teaching communities to fish sustainably,” Global Environment Facility ≫; “Mariculture in Southeast Alaska,” Ecotrust ≫
Recreational fishing restrictions and other local legislation will also be critical to protect key fisheries and bodies of water where, currently, overfishing and a lack of guidelines is greatly impacting fish stocks and ecosystem health.
To increase the number of sustainable fisheries, we need to increase the demand for sustainable fish and improve the seafood supply chain to significantly reduce fossil fuel usage and harm to our global waters. Restaurants and the food industry play a critical role in this. Restaurants and food manufacturers can choose to source their fish and seafood from sustainable fishers and fisheries, sourcing from local sustainable vendors whenever possible.5“Improve Your Sourcing,” World Wildlife Fund ≫
After all, independent research shows that 72% of seafood consumers across 21 countries agree that seafood needs to come from sustainable sources, and 54% said they are prepared to pay more for sustainable seafood.6“Seafood consumers put sustainability before price and brand,” Marine Stewardship Council ≫
Reducing plastic usage and transitioning to clean energy for food transport and manufacturing are also key changes within our food systems that will have a significant influence on not only our fish and oceans, but on our planet’s health as a whole.
Check out World Wildlife Fund’s extensive resource library to learn more about sustainable seafood.
Artisanal fishers, or career fishers who run smaller, private fishing operations across the globe, are already a step ahead when it comes to sustainability. Many artisanal fishers are already using sustainable fishing practices, such as limiting what fish species are caught to certain times of the year, giving them plenty of time to replenish.
What makes artisanal fishers such a driving force when it comes to sustainable fishing is that 90% of the global fishing industry is made up of artisanal fishers, and 66% of all seafood catches specifically for human consumption come from them. The problem stems largely from the fact that many of these fishers are local and do not have the resources or capacity to network far beyond their region to learn more about sustainable fishing practices and how these can further benefit the work they do and the communities that rely on them.
Subject-expert organizations need to partner with artisanal career fishers and other industry professionals to increase outreach, education, programming, and funding for further sustainable changes. Building a network of career fishers and environmental experts interested in helping to innovate and support one another will not only build resilient fisheries, but resilient communities across the globe.
Fishing on the mass scale that we see today involves removing huge quantities of our fish from their fresh and marine water ecosystems, but it also does significantly more harm. Other problematic practices like bottom trawling and ghost fishing largely impact the wildlife left behind, causing the further destruction of animal habitats and deaths.
Significantly reducing fossil fuel usage and transitioning to clean energy across the whole of the industry, establishing universal fishing guidelines that are regularly enforced, and working alongside scientists and researchers to implement data-informed strategies on when and where to fish are other ways commercial fisheries could make huge strides toward a more planet-friendly approach. Electric fishing vessels are one way scientists and engineers and working to advance clean solutions.9“Battery-Electric Fishing Vessel Marks a Sea Change for Small Commercial Fishers,” National Renewable Energy Laboratory ≫
However, when we talk about commercial, large-scale fishing and the immense impact this has on ourworld, we must remember that, in large part, we’re talking about corporations. And, as much as we plead our case for the health of the environment and global society, this doesn’t change the fact that corporations are largely motivated by profits. It will likely take significant policy changes and consumer demand to force the hands of these companies and instigate major transformation.
To make large-scale changes toward sustainable fishing, we need to have a large-scale approach—and that starts with governmental bodies. Alterations to subsidy programs, regulation of fish stocks, Marine Protected Areas (MPAs), and new harvesting policies are all ways in which governments at all levels (local, tribal, territorial, state, and federal) can take a stance and forge a path toward real environmental and social progress.
Since the Industrial Revolution began around 1750, carbon dioxide (CO₂) levels in our atmosphere have risen considerably. Like heat, our ocean absorbs a large amount of this CO₂, increasing the pH levels of surface-level seawater (a.k.a. ocean acidification). While generally harmful to all marine life, this acidification is particularly damaging for shellfish and corals as it interferes with their ability to build their shells and skeletons.
“The current rate of acidification is at least 100 times faster than any time period over the last few hundred thousands years and is it most likely unprecedented in Earth’s history.”
– Oceana
But our global oceans aren’t the only bodies of water being affected by acidification. Rising CO₂ levels in lakes, reservoirs, and other standing bodies of water has been documented as well, though it’s believed the excess carbon transfer to these bodies of water occurs through the surrounding vegetation. And as is the case with marine life, rising acidity in freshwater bodies negatively impacts the plant and animal species the ecosystem supports.11“Like Oceans, Freshwater Is Also Acidifying,” Scientific American ≫
Commercial fishing is the practice of catching fresh and marine water fish and other sea life for profit, conducted by commercial fishing boats. It’s a big $150 billion-a-year industry and the most widely distributed ocean-based activity worldwide. It significantly supports global food security as more than 3 billion people rely on seafood as a major form of protein.12“Commercial Fishing,” Global Fishing Watch ≫
Unfortunately, with an industry this large—one that still relies on fossil fuels and unsustainable fishing practices—commercial fishing leaves a substantial footprint. Half of all global fish stocks are overfished, leading many to collapse as they’re unable to replenish fish populations.13“Global Fishing Index,” Minderoo Foundation ≫
Commercial fishing relies significantly on fossil fuels, producing more annual carbon emissions (about 1 gigaton, or 2.2 trillion pounds) than the entire aviation industry (about 800 metric tons, or 1.8 million pounds). Notably, fishing corporations have worked alongside oil lobbyists to prevent the installation of offshore wind farms. (Although, this too is a nuanced conversation as many wind farms are located in ecologically sensitive waters with robust fisheries.)14“How Industrial Fishing Creates More CO₂ Emissions Than Air Travel,” Time Magazine ≫; “U.S. fishing industry teams up with oil lobby to fight offshore wind,” Reuters ≫
Most concerning is the industry’s lack of comprehensive planning or targets to initiate a transition toward a cleaner form of energy. With immediate implementation of strong regulations, it is estimated that we will see a reduction in annual carbon dioxide emissions by 81 million tons of CO₂ per year.15“Improved Fisheries,” Project Drawdown ≫
Bottom line, there is a lot of room for improvement where commercial fisheries are involved. However, there’s not much incentive for these companies to make changes given the profitability of what they’re doing—even though it’s causing what may soon become irreparable harm to our planet. Governments and other regulatory entities must step up to implement fishing limitations, better monitor and regulate the fishing practices taking place in their own waters, and enforce sustainable-first methodologies. This could include no-take zones, increased marine protected areas, or even wide-spread education on sustainable fishing practices.
The markers that help identify a balanced aquatic ecosystem are the same as those that apply to terrestrial ecosystems: biodiversity, stable plant and wildlife populations, and clean and intact habitats. Healthy ecosystems rely on balance—a balance between plants and wildlife, as well as a balance between what humans capture and what the ecosystem naturally provides.16“The survival of marine fauna depends on sustainable fishing,” Iberdrola ≫
When talking about an “ecosystem-based approach” to restoring and conserving healthy waters, this means ensuring a balanced aquatic ecosystem by identifying those factors that are causing damage and remedying them in a way that does not harm or alter the natural environmental systems in place.
The human benefits of a balanced aquatic ecosystem? Endless. But just to name a few, healthy fish populations mean improved food security, increased profits for fishers, and quality of life improvements for communities who rely on seafood and/or the fishing industry for survival.
The term “fishery” has multiple uses, though the two most common interpretations are as follows:
A fishery can be both the operation and the location of catching fish for recreational and commercial purposes alike and are often named for their target species (such as, a “Chinook fishery”17“Chinook Salmon,” NOAA Fisheries ≫). How the word is defined will depend largely on the context in which it’s being used. For example: “Artisanal fishing employs 90% of the captured fisheries workforce worldwide.” In this case, fisheries is being used in reference to the business or industry.
Similar to the overarching term of “agriculture” to refer to all activities involving the growth of crops and raising of livestock, aquaculture is the production and/or raising of aquatic organisms. This includes everything from growing and harvesting seaweed to breeding and raising fish or shellfish. Like agriculture, aquaculture is a method for producing food—only, it just so happens to be underwater. Aquaculture enhances fishery stocks when wild stocks are low and helps restore essential habitats, such as oyster reef restoration and outplanting. However, it’s important to remember that this work is not the same as restoring healthy wild stocks.18“Farmed Seafood,” World Wildlife Fund ≫
Today, aquaculture farms produce more than 50% of the fish and seafood used for human consumption. Unfortunately, these farms often pose hazards to surrounding natural ecosystems, including abundant antibiotic use and practices like open-net pens.19“Aquaculture,” NOAA Fisheries ≫; “Antibiotics in seafood farming,” Aquaculture Stewardship Council ≫
Open-net pen fish farming is the practice of placing large farms in open waters—rivers and marine waters—where fish are raised in their “natural” environment. The concentration of waste produced by these fisheries dangerously depletes oxygen from the surrounding water. These farms also can pass parasites and contaminants to wild fish stocks. When the waters become too contaminated to continue raising fish, the fisheries simply move location.20“Our Salmon. Our Sound.” Wild Fish Conservancy ≫; “Here’s Why We’re Working To End Open Net-Pens in B.C.” Wild Salmon Center ≫
“The use of hatcheries to propagate fisheries often results in domesticated stocks of fish (with reduced fitness compared to wild counterparts) and not the replenishment of wild stocks. Moreover, hatchery fish can have [harmful] impacts on wild populations through increased competition.”
– Melaney Dunne, Wild Salmon Center
Working alongside First Nations fishery managers and other key players on British Colombia’s Central Coast, Wild Salmon Center has helped develop the first-ever artificial intelligence tracker—paired with an ancient Indigenous fishing structure called a “weir” or “tidal weir”—to positively identify and track a dozen-plus fish populations as they migrate throughout the year.
This automated fish counting has huge implications for fishers, especially First Nations fishery managers, to more accurately predict population numbers, set harvest targets, and make informed decisions about emergency fishery closures. This technology has shown success in tracking salmon with scores ranging from 80% to 90% accuracy when tracking the coho and sockeye species of salmon.
