9 Fish and Shellfish You Can’t Legally Harvest in U.S. Fisheries
A fishing license doesn’t mean you can keep everything that bites. Some fish and shellfish are protected from harvest because their populations have declined, while others are prohibited under fishery-management rules. Atlantic sturgeon, smalltooth sawfish, and endangered abalone are among the species that belong in the water, not in a cooler headed for dinner.
The legal distinction matters: these are nine species subject to harvest or retention prohibitions in the U.S. waters or fisheries described below, not nine identical nationwide bans covering every possible transaction. Accidental capture differs from deliberately targeting or keeping a protected animal, and authorized research may have exceptions. Selling illegally harvested wildlife can also trigger the Lacey Act, which reinforces federal, state, and foreign wildlife laws.
Sturgeon Are Not Ordinary Catches
Atlantic sturgeon
Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) once supported fisheries for meat and caviar, but their five U.S. population segments are now federally protected. Four are listed as endangered; the Gulf of Maine population is threatened. NOAA Fisheries states, “It is illegal to fish for, catch, or keep sturgeon, including Atlantic, Shortnose, and Gulf.” That warning applies only to those protected sturgeons, not to every sturgeon species or every legally produced caviar product.
Shortnose sturgeon
Shortnose sturgeon (Acipenser brevirostrum) are a separate species, not young Atlantic sturgeon with a less impressive nose. They are listed as endangered throughout their range, and NOAA says anglers may not fish for, catch, or keep them. Protection has not eliminated the challenges they face: accidental capture and other human-related threats remain concerns. If one is hooked unintentionally, NOAA’s guidance is to release it carefully rather than turn an unexpected encounter into a retained catch.
Green sturgeon
Green sturgeon (Acipenser medirostris) bring the sturgeon warning to the West Coast. NOAA reports that retention is prohibited in both recreational and commercial fisheries throughout California, Oregon, and Washington. Its public guidance is direct: “It is illegal to fish for, catch, or keep green sturgeon.” The practical point is that a fish’s size does not make it legal to retain. Anglers need to identify the species and follow the applicable release rules, not simply check whether it would fit in the boat.
Reef Fish and Sharks Have Limits
Nassau grouper
Nassau grouper (Epinephelus striatus) are not interchangeable with the grouper offered at a seafood counter. NOAA says all harvest of this threatened species is prohibited in the United States, including Puerto Rico, the U.S. Virgin Islands, and U.S. exclusive economic zone waters. Applicable fishery rules also prohibit possession. “Grouper” is a broad common label, so the restriction must be tied to the actual species rather than stretched into a claim that all grouper fishing or sales are illegal.
Gulf grouper
Gulf grouper (Mycteroperca jordani) are another protected species—and their name can mislead readers. They are associated primarily with Mexico’s Gulf of California, not simply any grouper swimming off the U.S. Gulf Coast. NOAA lists them as endangered and states that all U.S. harvest is prohibited, with possession prohibited as well. Its final endangered-listing rule took effect on Nov. 21, 2016. Their tendency to gather predictably for spawning helps explain their vulnerability to overfishing.
Dusky shark
Dusky sharks (Carcharhinus obscurus) appear on NOAA’s prohibited-shark list for Atlantic highly migratory species fisheries. The agency’s commercial compliance guide says the listed prohibited sharks “may not be possessed or retained in any form.” Recreational guidance likewise prohibits targeting or retaining dusky sharks. The geographic qualification is essential: this is an Atlantic fisheries restriction, not evidence that every shark species is prohibited everywhere in the country. A shark’s legality depends on identification, location, and the rules governing that fishery.
Smalltooth sawfish
Smalltooth sawfish (Pristis pectinata) may look like sharks equipped with improbable power tools, but they are rays. Their U.S. population was listed as endangered in 2003, and the non-U.S. population followed in 2014. NOAA explains, “Under the ESA, it is illegal to catch, harm, harass, or kill an endangered sawfish.” Accidental encounters require immediate, careful release following species-specific guidance. The agency also asks people to report sightings or encounters at 844-472-9347 to help researchers track these rare animals.

Shellfish Protection Counts, Too
White abalone
White abalone (Haliotis sorenseni) show why this list extends beyond fish with fins. These marine snails were listed as endangered in 2001, becoming the first marine invertebrate protected under the Endangered Species Act. Their protected status means ordinary harvesting is not allowed; authorized conservation work is a different category. The species name matters here, too. A seafood product labeled “abalone” does not automatically establish a violation, because white abalone are not the only abalone species.
Black abalone
Black abalone (Haliotis cracherodii) once numbered in the millions along California’s coast, according to NOAA, but are now endangered throughout their range. They are algae-eating marine snails, not a darker market variety that collectors can freely gather. Their Endangered Species Act protection rules out ordinary take without applicable authorization. NOAA and its partners monitor remaining populations and habitats as part of recovery efforts, making an animal attached to a coastal rock a conservation concern rather than a free seafood opportunity.
These restrictions are not just about whether something is edible. They protect species whose recovery can be undermined by targeted fishing, retention, habitat damage, or illegal trade. Before fishing or collecting shellfish, check current federal and state rules for the exact species and location; if you accidentally catch a protected animal, follow its handling, release, and reporting guidance. The memorable catch can still become a story without becoming dinner or merchandise.
