Marine-conservation groups are celebrating after the U.S. House passed the America COMPETES Act on Friday.

The bill primarily boosts semiconductor production in the U.S. but a lesser-known provision would phase out an older type of fishing gear called drift gill nets in federal waters, something environmental groups have sought for decades.

Ben Enticknap is Pacific campaign manager and senior scientist at the nonprofit Oceana. He said the mile-long, nearly invisible gill nets are incredibly dangerous for marine life.

"They are set at night in the epicenter of ocean wildlife off the coast of southern California to catch swordfish," said Enticknap. "But they also catch whales, dolphins, sea turtles, sharks and many, many other animals."

The state of California already is phasing out its state drift gillnet permit program, which offers fishing crews cash to turn in their nets and permits, and helps them buy a new, safer type of gear called deep-set buoy gear.

All but four fishing boat captains in Southern California have begun the transition - and those four will have to follow if the bill becomes law.

Opponents of the bill, referring primarily to its provisions on manufacturing, say it is not tough enough on China.

Enticknap noted that it also would ban the sale of shark fins in the United States.

"We've already prohibited shark fins in California and Oregon and Washington," said Enticknap. "And this kind of takes that same approach that's already been passed by a number of states and makes it national."

A version of the COMPETES Act already has passed the U.S. Senate. Now the two have to be reconciled and passed again in both chambers before the final version can go to President Joe Biden's desk.

The Trump administration aims to increase domestic seafood production through industrial aquaculture but opponents said it puts Maine's coastal communities at risk.

Floating cages holding thousands of fish can harm native ecosystems by releasing pathogens and parasites into the ocean, harming the wild stocks on which local fisheries depend.

George Kimbrell, legal director at the Center for Food Safety, said aquaculture permits could be fast-tracked as proposed during Trump's first term.

"What we saw then and what we anticipate now is mirroring what the Trump administration has done in other areas, which is unfettered deregulation of industry," Kimbrell observed.

Supporters of large-scale aquaculture said it can help meet the growing demand for seafood while easing pressure on depleted fisheries but Kimbrell countered wild forage stocks are being overharvested
to ensure fish farms have enough fish food.

Small-scale aquaculture, including shellfish and marine plant farms, is boosting local Maine economies and creating jobs. Conservation groups argued large fin fish farms are similar to land-based concentrated animal feeding operations, or CAFOs, which create harmful amounts of waste and reduce jobs through automation.

Kimbrell explained the Trump administration wants more of them in federal waters.

"Establishing CAFOs of the sea is going to be very similar to what we've seen in Iowa and all across the U.S. in terms of its dramatic environmental impacts and its failure to provide an economic support for those communities," Kimbrell contended. "Instead of farmers, it will be fishers that will be displaced."

Kimbrell encouraged people to make informed decisions about their seafood and to support sustainably managed wild fisheries along with the nonprofits working to protect the ocean.

The National Oceanic and Atmospheric Administration has already identified so-called "aquaculture opportunity areas" starting in the Gulf of Mexico. Public comments on the permits are being accepted through Feb. 20.

At a recent pop-up in Healdsburg, California, to preview Chef Jacob Harth's forthcoming sustainable West Coast seafood restaurant, Winnie's, I tasted my first raw, line-caught Pacific sardines. (The tinned version stars in one of my first food memories, so this new experience was long overdue.) Cured in seaweed salt and gently warmed over coals, the dense and oily fish had been reeled in less than 24 hours before from the ocean off San Diego. But since commercial fishing of Pacific sardines was closed in 2015 (the third moratorium implemented since 1967 to rebuild the boom-and-bust population), how in the world did these forage fish end up on my fork?

Turns out, they were caught up in a targeted mackerel harvest and sold as bycatch, defined as "anything that is caught in the fishing process beyond the species and sizes of the targeted marine organisms," according to the Food and Agriculture Organization (FAO) of the United Nations. This definition casts a wide net and includes, for example, ocean sunfish (Mola mola), an unmarketable bycatch of the California swordfish fishery; the 10 orcas accidentally ensnared off Alaska's Aleutian Islands last year by bottom trawlers in pursuit of yellowfin sole and Pacific Ocean perch; and the Pacific sardines at Winnie's, an incidental catch of an otherwise protected, non-target but quite marketable species.

"Anytime you put a hook in the water, you can't be sure what's going to bite," says Dave Rudie, founder of the seafood market Catalina Offshore Products in San Diego. "So inevitably you're going to get some bycatch." Thanks to the active commercial ban on the fishery, the National Oceanic and Atmospheric Association (NOAA) currently considers the Pacific sardine stock "not overfished." So, onto my plate they went.

What is bycatch - and when is it edible?

"There are multiple meanings of bycatch depending on who you talk to," admits Elizabeth Hellmers, a senior environmental specialist with the California Department of Fish and Wildlife (CDFW). "But as long as their populations are healthy and being managed properly, it's beneficial for the entire production pathway [from fishers to consumers] to use as much bycatch as possible."

Domestic bycatch is monitored by the National Marine Fisheries Services and the U.S. Fish and Wildlife Service, with help from heavy-duty legislation like the Marine Mammal Protection Act, the Endangered Species Act, and a host of other legal provisions that aim to keep our sea stocks flourishing. Even though a 2018 assessment by the FAO estimates that bycatch amounts to nearly 10 percent of the global catch, an NOAA review of standardized bycatch reporting acknowledges that some information about bycatch is predictably anecdotal. "It's hard to count fish in or out of the sea," quips Harth.

Eclipsed by more newsworthy bycatch tragedies, the sustainable utilization of bycatch often goes unsung. Adrian Hoffman, cofounder of Bay Area-based Four Star Seafood (a "first receiver" that "lands" fish and shellfish directly from fishermen before distributing it to restaurants and markets), assumes that the average consumer doesn't think about bycatch much. Why would they need to when halibut, salmon and cod - the pelagic mainstays of American gastronomy - are always in ready supply at the grocery store?

"If consumers do think about bycatch," Hoffman says, "their impression of it is probably something like, 'Oh, some people went fishing and caught all this stuff they can't use, so they just threw it back over.'" Evidently, the average consumer of Hoffman's imagination is not far off the mark: conservation nonprofit Oceana reports that approximately 17 to 22 percent of annual U.S. bycatch is "discarded at sea, likely already dead or dying," while in Europe that number is closer to 50 percent, much to the detriment of marine environment.

Since the U.S. imports 62 to 65 percent of its seafood, utilizing bycatch seems like a legitimate strategy - along with, for instance, sustainable stateside aquaculture - to alleviate that burden. Rudie warns of the "transfer effect," or the shift in supply from well-managed U.S. fisheries to foreign fisheries with potentially questionable standards. "It's quite a trade-off," he says forebodingly.

In grassroots fashion, seafood purveyors and chefs are endeavoring to create awareness around utilizing bycatch, which is doubly sustainable if harvested through methods like hooks, harpoons, bottom-set longlines and traps. Slower and more targeted, these methods produce a micro-catch compared to the weighted bottom-trawler nets typically used in industrial fishing operations (which are very restricted, at least on the West Coast). Giant trawlers not only account for 78 percent of global discards, but they also send plumes of carbon dioxide into the atmosphere and contribute significantly to ocean acidification as they sweep the seabed indiscriminately.

Sustainably caught West Coast bycatch can include Pacific octopus and wolf eel from Dungeness crab pots and skate or dogfish from bottom-set longline black cod. "At some point we're going to need to be very familiar with bycatch," says Harth, "because that's all that's going to be left to eat if we keep going after the same old fish."

Advocating for bycatch

With Winnie's opening in summer 2025, and numerous pop-up previews until then, Harth continues his crusade to advance the use of bycatch and other undervalued sea species, a passion that originated while sportfishing with his father near their family home south of Tillamook Bay, Oregon, and commercial fishing for his erstwhile Portland seafood restaurant, Erizo.

Over the course of his lifelong seafaring history, Harth has developed certain insights about bycatch or even underutilized species. For instance, red and brown rock crab, which can be found in great abundance along the West Coast, make a more robust seafood stock compared to the highly sought-after Dungeness, which has a more delicate flavor despite being "stressed out." While lingcod and rockfish are common targets for rod-and-reel fishers casting off jetties in Oregon, the chef also enjoys the mild and flaky flesh of lesser-known cabezon or monkeyface eel that occasionally hook on the same lines. And at hyper-regional Erizo, he eschewed the wild mussels and ocean-farmed oysters from eastern Canada's Prince Edward Island - a frequent fossil fuel-guzzling flex on West Coast restaurant menus - for Oregon's own gooseneck barnacles, littleneck clams and surftide mussels, which more meaningfully evoked sense of place.

"If anyone could influence someone's opinion about bycatch species, it might be a chef or a restaurant," says Harth. Indeed, he is the latest in a legacy of toques who have fought food waste with kitchen initiatives; consider Dan Barber's WastEd series, which turned food scraps into delicious dishes like fried skate-wing cartilage and beet-pulp burgers, and Massimo Bottura's Food for Soul program, which feeds the homeless warm and nutritious meals made from high-quality restaurant discards. As Katherine Miller, author of "At the Table: The Chef's Guide to Advocacy," said in an interview with The Bittman Project, "Chefs are well suited to help accelerate advocacy work. They can help translate complicated topics into something easier to understand. [They] have too much influence on our food choices ... to just sit on the side lines."

Harth's advocacy brings attention to a waterfall of lost resources and opportunities - the hallmarks of a broken food system - associated with blindly jettisoned legal bycatch, which include but aren't limited to a recreational fisherman's missed meal, the massive carbon demand of importing seafood from foreign countries, and the overfishing of popular species. His activism also manifests in a respectful, elevated approach to preparing these so-called discards: In his purview, house-made butter is flavored with smoked Kellet's whelks, a bycatch of Santa Barbara's lobster fishery. Of the Pacific octopus often found in crab pots, he makes wood-grilled skewers slicked in wild mushroom oil. (Doing their part for the survival of the species, Pacific octopus spawn hundreds of thousands of eggs and die soon after, often at the claws of crabs, which is why they're regularly found in the pots.) And turning purple sea urchin into uni-on-toast is especially beneficial, since the urchin is an invasive species with a voracious appetite for the valuable kelp forests along the Mendocino Coast.

But if mild white fish is the extent of your seafood palate (no judgment here), Harth assures that wolf eel and the small shark species dogfish - whose low marketability in the U.S. may be due to their canine-related monikers among other stigmas - will readily appeal. What's considered bycatch in America may be target catch elsewhere in the world, theoretical proof of concept for their culinary applications. In Ensenada, Mexico, dogfish and angel shark are the preferred proteins for Baja-style fish tacos - a nod to the 1950s and '60s Japanese fishermen who introduced their traditional tempura-battered shark to the region. "That's part of the appeal of most bycatch," says Harth. "It's different, but also familiar."

Marketing for sustainability

Also fighting current on the way to marketability is opah, the world's only fully warm-blooded fish species, a biological advantage that helps them swim, digest and react faster than their cold-blooded cohorts in cold, deep ocean. Its flesh may have a beautiful pinkish-orange hue reminiscent of tuna, but some of its cuts, particularly the adductor muscle, taste entirely, well, beefy. And flavor hasn't been the only barrier to more widespread inclusion on the American dinner table: Its appearance is also unusual. Opah looks almost celestial, with gold-rimmed eyes and a full moon-shaped body that's speckled, silvery and rosy around the edges. For some, the fish may look too otherworldly to eat.

In 2013, Dave Rudie of Catalina Offshore Products received a call from fishermen who were harvesting Pacific bluefin tuna between Hawaii and California. They had found the target species in high numbers, though a significant fraction of the catch comprised opah. Still, Rudie agreed to purchase their 30,000-pound harvest, and subsequent monthly deliveries thereafter, to reboot the tuna supply in San Diego specifically for the sushi market. The city's once-booming tuna canneries ceased operations in the 1970s and '80s, parallel to the decline of Pacific bluefin and yellowfin species in the area due to overfishing.

"But opah was not a popular fish," Rudie says, "so we had to figure out how to sell it." He applied for, and received, NOAA's Saltonstall-Kennedy Grant, which funds efforts to "help fishing communities optimize economic benefits by building and maintaining sustainable fisheries." Catalina Offshore began working with the Southwest Fisheries Sciences Center to find ways to promote the fish using social media, retail sales and local chefs' innovative recipes, such as opah burgers and opah pastrami.

Their marketing savvy paid off. But just as demand for the fish began to rise, the amount of opah bycatch began to trough. "Good old supply and demand," muses Rudie, who sold Catalina Offshore about a year ago and has since pivoted to promoting yet another misunderstood species, the aforementioned purple sea urchin. "That's the free-world capitalist system for you."

Bycatch for the future

The latest Fisheries Economics of the United States Report, from 2022, revealed that the U.S. commercial and recreational saltwater fishing industry generated $321 billion in sales and supported 2.3 million jobs. Climate activist Ian Angus traces the origins of capitalism back 5,000 years to when "fishing for sale rather than consumption developed with the emergence of class-divided urban societies." Additionally, he cites the first mention of overfishing in texts dating back nearly 2,000 years, when the Roman poet Juvenal lamented having to import fish from Corsica and Sicily because "our waters are already / Quite fished-out, totally exhausted by raging gluttony." Sounds like overfishing, or the depletion of fish stocks due to a faster rate of harvest compared to the natural tempo of renewal, is a tale as old as time.

Can utilizing bycatch tackle such an ancestral problem? Maybe not entirely, but Hellmers of the CDFW thinks that using less-popular species can at least take "a little bit of pressure" off the main ones. "We have a huge demand for seafood in this country, so anything that can be used and sold is beneficial for the fishers, the consumer, and from a management perspective," she says.

If the importance of utilizing bycatch isn't obvious by now, consider the fact that such familiar fins of American eating - like petrale sole, ocean perch and Chinook salmon - are among the 30 species presently considered threatened and endangered from overfishing, dams and pollution in the California Current, an oceanic current and dynamic ecosystem that flows from southern British Columbia, Canada, to southern Baja California, Mexico. In 2018, the fall-run Chinook that historically spawn in the Klamath and Sacramento Rivers were determined overfished; in 2023, the fisheries were "declared a disaster" by California's secretary of commerce. Even though Chinook and other salmon runs like coho have been in decline for decades, California has only canceled the last two salmon seasons. Currently considered non-legal bycatch in the Golden State, captured salmon must be released back to the waters from whence they came.

But perhaps the proverbial tides are turning. Earlier this year, dams along the Klamath, a major California-Oregon watershed, were removed and salmon have since been spotted in reaches of the river formerly unreachable for more than a century. Despite the potential to appeal to a wider audience once salmon fishing comes back online, Harth plans to stay the bycatch course. "There will need to be many, many more improved seasons for me to even consider putting salmon on my menu," says Harth. And likely no shortage of bycatch to fill the void.

Fish, once a Friday penance for many, has recently become the "good meat" poster child. Fish farming has been touted as a way to help protect wild marine animals and, by some, even a way to feed the world. Yet a new study in Science Advances makes the case that farming fish comes at a much higher cost than previous estimates suggest, because of how much aquaculture relies on wild fish. According to the researchers, the total mass of wild fish required to produce farmed fish could be 536 percent higher than previous estimates. The drain on wild fish populations can in turn make it harder for vulnerable communities to find food. One of the core arguments for farmed fish - the idea that it protects wild fish by leaving them in the sea - ignores the fact that aquaculture relies on feed made from wild anchovies, sardines, herring, mackerel and other fish that many coastal nations rely on for sustenance.

The field of fish farming is no stranger to criticisms: overcrowded pens; poor fish health; inhumane killing methods; pollution; plastic waste from nets used to create pens, as well as diseases (spread by escaped farmed fish) that cause health problems for wild fish populations.

Nonetheless, the practice is growing. Farmed fish production is expected to have expanded by over 17 percent between 2022 and 2032, according to the United Nations Food and Agriculture Organization. By 2050, global demand for fish is expected to nearly double, thanks in part to an ever-increasing output of farmed seafood. Over a similar period, demand for fishmeal - the feed carnivorous farmed fish like salmon, trout and bass rely on - is projected to grow over seven percent by 2030.

"This is a hot topic in academic circles, but I don't think the public understands how fish farming works, especially in terms of its reliance on wild fish," Spencer Roberts, an environmental science and policy researcher at the University of Miami and a co-author of the new study, tells Sentient. In reality, says Roberts, aquaculture has simply shifted pressure from one set of fish to another.

The need for fish feed is creating problems for people too. "When we hear about fish farming feeding the world, it's not true. The reality is that it's starving people...in places like West Africa where 'reduction fisheries' are taking their fish," says Roberts, and selling or using them to turn into fishmeal. "Subsistence fishing communities are literally starving and being forced to emigrate," Roberts adds.

Part of how the aquaculture industry sold itself as the more sustainable option is thanks to what's known as the fish-in-fish-out ratio - the measurement of how many wild fish it takes to feed farmed ones. This figure, in essence, compares the number of how many wild fish are used as feed for fish farming, versus how many come out to feed humans. The calculation is used by the industry to demonstrate its efficiency, and therefore, its sustainability. It's used to make the case for how large a role it should play in a future with a growing global population, increasing planetary warming and shrinking natural resources, like farmland to grow food.

By focusing only on the ratio, Roberts and his co-authors argue, the true number of wild fish used to feed farm ones ends up obscured - indirect deaths are ignored, essentially - while outputs are maximized. This creates a misleading measurement.

There are a number of ways this plays out, but here's one example: so-called fish trimmings. Trimmings, which are the parts of the fish people don't traditionally eat (heads, tails and so on), are conventionally classified as by-products and subtracted on the basis that they are not wild fish. But according to a representative from The Marine Ingredients Organizations, only about 20 percent of trimmings for fishmeal come from farmed fish. The other 80 percent is from wild fish.

Once you adjust the calculation for the fish trimmings and other factors, the study finds, the volume of wild fish used to feed farmed fish could be over 300 percent higher than standard estimates. Taking other factors into account - when farmed fish that don't eat fishmeal are excluded, and indirect mortalities like slippage are included - it's even more dramatic. The total wild fish mass, according to the study, could be 536 percent higher.

It is not yet possible to convert the study's new percentage estimates into wild fish numbers, but Roberts says researchers working on the question believe reduction fisheries account for most fish taken from the ocean each year, killing over a trillion wild animals. These are animals who could otherwise be maintaining ocean health simply by staying in the sea, or helping to feed vulnerable populations.

Responses from fishmeal trade bodies to the new study varied, with the Marine Ingredients Organization favoring "a shared metric system" of lifecycle assessments, rather than fish-in-fish-out, and linking to a study that supports these as "the pathway to improved sustainability for all feed ingredients." A life cycle assessment quantifies the environmental impacts of a product, system or service from beginning to end.

The Federation of European Aquaculture Producers' general secretary Javier Ojeda was more upbeat about the study, saying its average ratio confirms that farming of fish reliant on fishmeal "is a net producer of aquatic food [which] should be heralded as great news," rather than a way to "demonize" it.

The Problem with Dewilding the Ocean

Fish farming creates another problem: dewilding. Separately, another new study finds mariculture - fish farming that takes place in the sea - is contributing to oceanic dewilding. Dewilding is a term for prioritizing human interests over ecosystems and, essentially, destroying the natural or wild world. Fish farms pollute the ocean too, with fish feces and uneaten food from farms creating excess nitrogen and phosphorus that can lead to algae blooms, depriving the water of oxygen.

The study looks at different dewilding categories, one of which is conceptual dewilding. Conceptual dewilding is a category that deals with human perceptions, which can set the stage for uncontrolled exploitation, says Becca Franks, co-author and assistant professor of environmental studies at New York University.

"The ocean is less explored than the moon... [but] as we map it for more places to put farms in and start to see it as a place to extract more resources from, the less we see it as a wild place, and the more we are going to be casual about destroying it," Franks tells Sentient.

Findings by Roberts and his team that aquaculture's dependence on wild fish is underestimated, are, Franks says, an example of "this rough, casual" approach to marine environments, and evidence that we are "not looking at the ocean as a wild space that should be approached with respect and caution."

Franks offers an example of humanity turning from a rough approach to a respectful one: whales. "We used to see them as floating oil reserves ...[but] with enough organizing and attention to who they actually were ... and allowing a bit of poetry to come in ... [we have] completely changed the way we think about whales, and it has allowed them to do better."

The bottom line, according to Franks, is that the critical role of oceans in storing carbon and mitigating climate change means we should take a very careful look at what kinds of aquaculture we want to proceed with, adding, "the details really matter."
