Horseshoe Crabs and Red Knots Are In Peril

Jessica R. Clarke • August 3, 2021

The Chesapeake Bay’s 64,000-square-mile watershed covers parts of six states and is home to more than 18 million people. We all know how important the Bay is to our blue crabs.  

Across Delmarva, another bay - Delaware Bay – is a critical point for another “crab,” the horseshoe crab, a critical link to biodiversity and for migratory Red Knots and other shorebirds.

Horseshoe crabs lay millions of eggs on Delaware beaches, feeding shorebirds, fish, and other wildlife. Their large, hard shells serve as microhabitats for many other species, such as sponges, mud crabs, mussels, and snails. The world’s largest spawning population of horseshoe crabs is found in Delaware Bay.


Delaware Bay is also a critical stopover point for Red Knots on their annual migration from their wintering grounds at the southern tip of South America to their Arctic breeding area. This is one of the longest migrations in the avian world, more than 9,000 miles. Over half of the Western Atlantic flyway’s Red Knots, Ruddy Turnstones, and Semipalmated Sandpipers rely on the Delaware Bay each spring. It is the birds’ last chance to gain sufficient energy reserves for the breeding season.

 

Unique Ecological Relationship between Horseshoe Crabs and Red Knots

 

Horseshoe crabs are not really crabs; they are more related to spiders. They appeared on Earth over 400 million years ago, before dinosaurs. Today, horseshoe crabs are considered living fossils.

 


Males, often more than one at a time, trail behind the larger females and externally fertilize her 60,000 to 120,000 eggs, which she then buries near the high tide line. The small, green eggs are food for shore birds, fish, and other wildlife; they are critical for the migrating Red Knot.

 

After the surviving horseshoe crab eggs hatch, the juveniles return to the Bay. Once they mature in eight to 10 years, they come to shore again only to mate. Horseshoe crabs shed their outer shells 16 or 17 times before they become adults. Those shells, scattered on beaches throughout the summer and fall, are often mistaken for dead horseshoe crabs. They are the remains of the animals’ outgrown exoskeletons.

 

The Red Knot’s spring migration begins in mid-February from their wintering grounds in South America. By mid-April, they have reached southern Brazil, believed to be the last area in South America where they feed and gain weight. By the middle of May, large numbers of Red Knots arrive at Delaware Bay to refuel before completing their journey. Their arrival coincides with the spawning of horseshoe crabs on Delaware Bay’s beaches.

 

By the end of May or the first few days of June, the migrating birds have departed on the last leg of their journey, reaching the Arctic just as the snow is melting and abundant insect life is emerging. Once there, they have just enough time to establish nesting sites, perform courtship displays, incubate eggs, and replenish their energy reserves before their autumn migration begins again in mid-July.

 

Because the Arctic season is so short, there is almost no room for delay. If they have not accumulated enough fat reserves at the Delaware Bay stopover, or if the Arctic insects have not emerged until after the birds have laid their eggs, they will likely not be able to breed.

 

Threats

 

Delaware Bay’s horseshoe crabs are imperiled by overharvesting for bait and biomedical tests. Horseshoe crab blood contains copper instead of the iron that gives human blood its red color. That “blue blood” is the key ingredient in Limulus Amebocyte Lysate (LAL), used to test vaccines and medical equipment for bacterial contaminants that could be introduced during the manufacturing process. That blood, when harvested, currently goes for $60,000 a gallon.

 

Threats such as oil spills and other pollution, habitat loss from development or shoreline alterations to prevent erosion, along with other human disturbances, and sea level rise due to climate change are only a few of the threats to Red Knots. Competition with gulls for food and reduced food availability also affect the Red Knots’ complicated spring migration.

 

The population of Red Knots has dropped to the lowest level since counts began 40 years ago — fewer than 7,000, down from 90,000 in the early 1980s. The population drop this year is attributed to cold ocean temperatures which delayed the spawning of horseshoe crabs last year until early June. By then, the Red Knots and other shorebirds had already left for their breeding grounds. Because they were unable to refuel in the Delaware Bay, it is estimated that 40% of the migrating birds never arrived, lacking the energy reserves to reach the Artic.

 

Some Progress

 

Threats of declines among horseshoe crabs and their valuable eggs and the environmental threats to Red Knots and other shorebirds remain.

 

The Red Knots’ extinction has, so far, been prevented by regulations limiting the harvesting of horseshoe crabs for bait. The regulations moderated the steep decline of the horseshoe crab population; however, Red Knot numbers are slow to recover. This year’s setback puts the survival of the Red Knot at severe risk.

 

Awaiting FDA approval is Recombinant Factor C (rFC), a synthetic alternative to LAL, the “blue blood” needed for testing vaccines and medical equipment for contamination. The synthetic has been available since 2003 for vaccine and medical equipment testing but, so far, not to researchers.

 

Conservationists are calling for an immediate ban on harvesting horseshoe crabs for bait. Since 1996, Maryland’s commercial fishery has operated under a quota system for horseshoe crabs. In 2013, the harvest of female horseshoe crabs was prohibited, and quotas were set for males. New Jersey implemented a full moratorium on horseshoe crab bait harvest in 2008. Delaware allows the bait harvest of male crabs under a quota system.

 

Research to identify supplemental and artificial baits for the conch and eel fisheries is being conducted. Because horseshoe crabs do not breed before age nine or older, it may take some time before the population measurably increases.


The Atlantic States Marine Fisheries Commission, with representatives from each state on the Atlantic Coast, developed a horseshoe crab management plan, state-by-state harvest quotas, and created a 1,500 square mile Horseshoe Crab Sanctuary off the mouth of the Delaware Bay. Since 2004, a closed season during May helps to ensure that shorebirds have sufficient eggs to feed upon.

 

However, the Horseshoe Crab/Red Knot connection remains threatened whenever regulations are not enforced and the supply of the eggs that migrating birds depend upon is reduced.

Common Sense for the Eastern Shore

By John Christie February 17, 2026
These are the words from Emma Lazarus’ famous 1883 sonnet “The New Colossus” inscribed on a bronze plaque on the pedestal of the Statue of Liberty. In 1990, Congress reaffirmed this vision of America by establishing the Temporary Protected Status program. TPS is designed to provide humanitarian relief to foreign nationals in the United States who come from disaster-stricken countries. In its present form, the TPS legislation gives the Secretary of the Department of Homeland Security responsibility for the program. However, the legislation prescribes the kind of country conditions severe enough to warrant a designation under the statute, the specific time frame for any such designation, and the process for periodic review of a TPS designation which could culminate in termination or extension. All initial TPS designations last from six to eighteen months. Before the expiration of a designation, the statute mandates that the Secretary shall review the conditions in the foreign state to decide if the conditions for the designation continue to be met, following consultation with appropriate agencies of the government. Extension is the default; the designation “shall be extended” unless the secretary affirmatively determines that conditions are “no longer met.” ------------------------------------------------------------- A massive earthquake devastated Haiti in January 2010, and precipitated an unprecedented humanitarian crisis. Shortly after, then-DHS Secretary Janet Napolitano, after consultation with the State Department, designated Haiti for TPS due to “extraordinary conditions.” Haitian nationals in the United States continuously as of January 12, 2010, could thus apply for TPS, and obtained the right to remain and work in the U.S. while Haiti maintained its TPS designation. Napolitano set the initial TPS designation for 18 months. As Haiti’s deterioration worsened, successive DHS secretaries have extended this program. Gang violence and kidnappings have spiked. In 2021, a group of assailants killed Haiti’s then-President Jovenel Moïse. In 2023, another catastrophic earthquake hit Haiti. In 2024, in response to these conditions, then-DHS Secretary Alejandro Mayorkas once again extended and redesignated Haiti for TPS, this time effective through February 3, 2026. During the 2024 election cycle, the GOP candidate, Donald Trump clearly indicated that time had not tempered his views on Haiti, characterized by him as a “shithole country” during his first term. He stated that when elected, he would “absolutely revoke” Haiti’s TPS designation and send “them back to their country.” On December 1, 2025, Kristi Noem, DHS secretary in the second Trump administration, announced, “I just met with the president. I am recommending a full travel ban on every damn country that’s been flooding our nation with killers, leeches, and entitlement junkies. Our forefathers built this nation on blood, sweat, and the unyielding love of freedom, not for foreign invaders to slaughter our heroes, suck dry our hard-earned tax dollars, or snatch the benefits owned to Americans. We don’t want them, not one.” So says the official responsible for overseeing the TPS program. And one of those (her word) “damn” countries is Haiti. Three days before making the above post, Secretary Noem announced she would terminate Haiti’s TPS designation as of February 3, 2026. Five Haitian TPS holders filed suit in federal court in Washington initially seeking an injunction against the termination of the Haitian TPS program pending the completion of the litigation. These plaintiff TPS holders are not “killers, leeches, or entitlement junkies.” They are instead a neuroscientist researching Alzheimer’s disease, a software engineer at a national bank, a laboratory assistant in a toxicology department, a college economics major, and a full-time registered nurse. The case was assigned to district court judge Ana Reyes who granted the plaintiffs’ injunction request on February 2, 2026, by way of an 83-page opinion. The plaintiffs charge that Secretary Noem preordained her termination decision because of hostility to non-white immigrants. According to Judge Reyes, “This seems substantially likely. Secretary Noem has terminated every TPS country designation to have reached her desk — twelve countries up, twelve countries down.” Judge Reyes also decided that Noem’s conclusion that Haiti (a majority non-white country) faces only “merely concerning” conditions cannot be squared with the “perfect storm” of “suffering and staggering” humanitarian toll described in page after page of the record in the case. In Judge Reyes’ view, Noem also ignored Congress’s requirement that she review the conditions in Haiti “after consulting with appropriate agencies.” Indeed, the record indicates she did not consult other agencies at all. Her “national interest” analysis focuses on Haitians outside the United States or here illegally, ignoring that Haitian TPS holders already live here and legally so. And though Noem states that the analysis must include “economic considerations,” Judge Reyes concluded Noem ignored altogether the billions that Haitian TPS holders contribute to the economy. The administration’s primary response in the litigation has been to assert that the TPS statute gives Secretary Noem “unbounded” discretion to make whatever determination she wants, any way she wants. Yes, Judge Reyes acknowledges, the statute does grant Noem some discretion. But, in Judge Reyes’ opinion, “not unbounded discretion.” To the contrary, Congress passed the TPS statute to standardize the then ad hoc temporary protection system; in Judge Reyes’ words, "to replace executive whim with statutory predictability.” The administration also argued that the harms to Haitian TPS holders were “speculative” if they are forced to return to Haiti. Because the State Department presently warns, “Do not travel to Haiti for any reason,” the administration asserts that harm is “speculative” only because DHS “might not” remove them. However, according to Judge Reyes, this argument fails to take Secretary Noem at her word: “We don’t want them. Not one.” The public interest also favors the injunction, in the opinion of Judge Reyes. Secretary Noem complains of the strains that unlawful immigrants place on our immigration-enforcement system. Noem’s answer is to turn 352,959 lawful TPS Haitian immigrants into unlawful immigrants overnight. Noem complains of strains to our economy; her answer is to turn employed lawful immigrants who contribute billions in taxes into the legally unemployable. Noem complains of strains to our health care system. Noem’s answer is to turn the insured into the uninsured. “This approach is many things – but the public interest is not one of them,” according to Judge Reyes. The opinion of Judge Reyes concludes: “Kristi Noem has a First Amendment right to call immigrants killers, leeches, entitlement junkies, and any other inapt name she wants. Secretary Noem, however, is constrained by both our Constitution and the law to apply faithfully the facts to the law in implementing the TPS program. The record to-date shows she has yet to do that.

Gov. Wes Moore signed legislation on February 17, 2026, to prohibit State and local jurisdictions from deputizing officers for federal civil immigration enforcement activity. The law, created under SB 245/HB 444 , is effective immediately. “In Maryland, we defend Constitutional rights and Constitutional policing — and we will not allow untrained, unqualified, and unaccountable ICE agents to deputize our law enforcement officers,” Moore said. “This bill draws a clear line: we will continue to work with federal partners to hold violent offenders accountable, but we refuse to blur the lines between state and federal authority in ways that undermine the trust between law enforcement and the communities they serve. Maryland is a community of immigrants, and that's one of our greatest strengths because this country is incomplete without each and every one of us.” “As an immigrant, this bill is deeply personal to me,” said Lt. Gov. Aruna Miller. “Immigrants make Maryland stronger every day, and our communities are safer when everyone feels protected and valued. This legislation ensures that our law enforcement resources remain focused on keeping Marylanders safe, not on actions that create fear in our neighborhoods. I thank the bill sponsors and Governor Moore for their leadership in ensuring Maryland remains a place where dignity and opportunity go hand in hand.” U.S. Department of Homeland Security Immigration and Customs Enforcement, also known as ICE, established its 287(g) program to authorize local law enforcement officials to perform federal civil immigration enforcement functions under ICE’s oversight. Under SB 245/HB 444, State and local jurisdictions in Maryland are prohibited from engaging in such agreements. Any local jurisdictions with standing 287(g) agreements must terminate them immediately. The legislation does not: Authorize the release of criminals Impact State policies and practices in response to immigration detainers that are issued by the U.S. Department of Homeland Security Prevent the State or local jurisdictions from continuing to work with the federal government on shared public safety priorities, including the removal of violent criminals who pose a risk to public safety Prevent State or local jurisdictions from continuing to notify ICE about the impending release of an individual of interest from custody or from coordinating the safe transfer of custody within constitutional limits State and local law enforcement will also maintain the ability to work with the federal government on criminal investigations and joint task forces unrelated to civil immigration enforcement. Any individual who is charged with a crime is entitled to due process and, if convicted, must serve their sentence.

When I practiced law, much of my litigation involved issues arising under federal antitrust laws. The Department of Justice (DOJ) was my frequent adversary in court. In some cases, DOJ challenged a client’s conduct as anticompetitive. In others, they claimed an intended client merger would create a monopoly. Some of these DOJ court battles were won, others were not. Overall, I had great respect for DOJ lawyers. They were professional, well prepared, and dedicated to their mission of seeing justice done. They were courteous, honest, and forthright with the courts before which we argued our cases. In those days, without resorting to social media or press conferences, the DOJ spoke entirely through its court filings. Although as an advocate I took issue with various DOJ investigatory decisions as well as decisions to initiate litigation, I never thought politics was involved. Post-Watergate internal rules strictly limited communication with any figures at the White House. Not so, it seems, anymore. Beginning last January 20, all of this changed rapidly and spectacularly . On March 14, Trump triumphantly arrived at the main DOJ building in D.C. to be welcomed by a group of carefully selected VIPs. He was greeted by Pam Bondi, his chosen new attorney general, who exclaimed, “We are so proud to work at the directive (sic) of Donald Trump.” Bondi’s boast that the DOJ now worked at the president’s behest was something never said before and, in effect, surrendered the department’s long and proud independence. And Bondi’s comment was not an empty gesture. As chronicled by reporters Carol Leonnig and Aaron Davis in their new book, Injustice: How Politics and Fear Vanquished America’s Justice Department , within hours of being sworn in, Trump and his lieutenants began punishing those at the Justice Department who had investigated him or those he considered his political enemies. Career attorneys with years of experience under many administrations were fired or reassigned to lesser work, or they resigned. As Leonnig and Davis report, what followed was “the wholesale overthrow of the Justice Department as Trump insert[ed] his dutiful former defense attorneys and 2020 election deniers atop the department.” [Source: Injustice , p. xix.] In the place of years of experience, the new team appears credentialed simply by loyalty to the president’s causes. The DOJ’s conduct in court has since caused damage to judicial and public faith in the integrity and competence of the department. Just Security is an independent, non-partisan, daily digital law and policy journal housed in the Reiss Center on Law and Security at the New York University School of Law. Since January 20, it has documented federal judicial concerns about DOJ conduct. In 26 cases, judges raised questions about DOJ non-compliance with judicial orders and in more than 60 cases, judges expressed distrust of government-provided information and representations. This count was taken the day after a federal court dismissed the DOJ cases against former FBI Director James Comey and New York Attorney General Letitia James. [Source: Just Security , “The ‘Presumption of Regularity’ in Trump Administration Litigation,” Nov. 20, 2025.] As summarized by the Georgetown Law Center’s Steve Vladeck, “It’s one thing for the Department of Justice to so transparently pursue a politically motivated prosecution. But this one has been beset from the get-go with errors that remotely competent law students wouldn’t make. Indeed, it seems a virtual certainty that the Keystone Kops-like behavior of the relevant government lawyers can be traced directly to the political pressure to bring this case; there’s a reason why no prosecutors with more experience, competence, or integrity were willing to take it on.” [Source: One First , Nov. 24, 2025.] Rather than accept criticism and instead of trying to do better, Bondi’s DOJ and the Trump administration lash out in a fashion apparently aimed at demeaning the federal judiciary. At a recent Federalist Society’s National Lawyers Convention, Deputy Attorney General Todd Blanche, one of Trump’s former defense attorneys, attributed the Trump administration’s myriad losses in the lower federal courts to “rogue activist judges.” He added, “There’s a group of judges that are repeat players, and that’s obviously not by happenstance, that’s intentional, and it’s a war, man.” Deputy Chief of Staff Stephen Miller decries each adverse ruling against the Trump administration as just part of a broader “judicial insurrection.” Not to be left behind, Trump himself regularly complains of “radical left lunatic” judges. In addition to the harm these comments inflict on the federal courts, their premise is simply not true. According to a survey by Vladeck, as of Nov. 14, there were 204 cases in which federal district courts have ruled on requests for preliminary relief against the Trump administration. In 154 of them, district judges granted either a temporary restraining order, a preliminary injunction, or both. Those 154 rulings came from 121 district judges appointed by seven presidents (including President Trump) in 29 district courts. In the 154 cases with rulings adverse to the Trump administration, 41 were presided over by 30 Republican-appointed judges, fully half of whom were appointed by President Trump. No, it is no longer your grandfather’s Department of Justice. John Christie was for many years a senior partner in a large Washington, D.C. law firm.

The Salisbury City Council has appointed longtime public servant Melissa D. Holland to fill the vacancy in District 2. Holland was selected on Dec. 1 after the council reviewed several applicants. A 27-year resident of Salisbury, Holland brings more than 20 years of experience in government, education, and administration. As executive assistant to the president of the University of Maryland Center for Environmental Science, she currently oversees operations, budgeting, communications, and planning. Before joining UMCES, Holland worked for nearly 11 years with the Wicomico County Council, gaining extensive experience in legislative procedure, constituent services, research, and budget preparation. Her background includes positions with the Wicomico County Board of Education, the State of Maryland’s Holly Center, and multiple early-learning programs. Approved by a 3-1 council vote, Holland was selected based on her administrative expertise and long-standing community involvement. (Salisbury’s City Council is now comprised of only women.) She has a bachelor’s degree in legal studies from Post University and an associate degree from Wor-Wic Community College. She has also served as PTA president at East Salisbury Elementary and Wicomico Middle School. In her application, Holland emphasized her commitment to maintaining transparency in city government and ensuring that District 2 residents remain informed and represented. “I plan to be well-informed on the issues that matter to the citizens of Salisbury and to listen to their concerns carefully,” she wrote. “I want to make a positive and lasting impact on our city.” Holland’s appointment restores the City Council to full membership as it faces debates over budgeting, infrastructure planning, and local governance initiatives. She is expected to begin constituent outreach immediately and participate fully in the selection of the next council president.

Voters in Hurlock have delivered sweeping changes in this year’s municipal election, as Republican and GOP-aligned candidates won key races there. The results mark a setback for Democrats and a significant political shift in a community that has historically leaned Democratic in state and federal contests. The outcome underscores how local organizing and turnout strategies can have an outsized impact in small-town elections. Analysts also suggest that long-term party engagement in municipal contests could shape voter alignment in future county and state races. Political analysts warn that ignoring municipal elections and ceding them to the GOP could hurt the Maryland Democratic Party in statewide politics. Turnout increased by approximately 17% compared with the 2021 municipal election, reflecting heightened local interest in the mayoral and council races. Incumbent Mayor Charles Cephas, a Democrat, was soundly defeated by At-Large Councilmember Earl Murphy, who won with roughly 230 votes to Cephas’s 144. In the At-Large Council race, Jeff Smith, an independent candidate backed by local Republicans, secured a 15-point win over Cheyenne Chase. In District 2, Councilmember Bonnie Franz, a Republican, was re-elected by 40 percentage points over challenger Zia Ashraf, who previously served on the Dorchester Democratic Central Committee. The only Democrat to retain a seat on the council was David Higgins, who was unopposed. The Maryland Republican Party invested resources and campaign attention in the Hurlock race, highlighting it on statewide social media and dispatching party officials, including Maryland GOP Chair Nicole Beus Harris, to campaign. Local Democrats emphasized support for Mayor Cephas through the Dorchester County Democratic Central Committee, but the Maryland Democratic Party did not appear to participate directly.
