The harvest of horseshoe crabs, a practice that has long been associated with the commercial fishing industry, has become a subject of increasing concern among conservationists in recent years.
This concern arises from the recognition of the crucial role that horseshoe crabs play in coastal ecosystems.
Of particular significance is their role in providing a vital source of food for a subspecies of bird known as the red knot. These migratory shorebirds, characterized by their distinctive rust-colored plumage, have been listed as threatened under the Endangered Species Act.
The red knot relies heavily on the eggs of horseshoe crabs as a critical source of sustenance during their long migration journeys. As the population of horseshoe crabs declines due to overharvesting, the availability of this essential food source for the red knot is also being jeopardized, further exacerbating the precarious situation faced by this already threatened bird species.
Conservationists are therefore calling for urgent action to address the issue of horseshoe crab harvesting in order to safeguard the delicate balance of coastal ecosystems and protect the red knot from further decline.
In the ever-changing natural world, the remarkable journey of migratory birds, spanning a vast distance of approximately 19,000 miles (30,577 kilometers) from South America to Canada, stands as a captivating spectacle of endurance, survival, and adaptation.
Amidst this awe-inspiring feat lies a crucial need for the red knot, an avian species known for its remarkable migration, to engage in periodic stops to replenish their energy reserves.
As these extraordinary creatures undertake their arduous journey, the availability and conservation of horseshoe crabs emerge as integral factors in their continued existence.
Bethany Kraft, the esteemed senior director for coastal conservation at the Audubon Society, asserts that enhanced protection measures should be put in place to safeguard these vital marine organisms, for the red knot’s survival hinges upon it.
Regrettably, despite the recognition of the importance of horseshoe crabs, the guidelines governing their handling remain voluntary rather than mandatory, leaving the red knot species vulnerable to unforeseen hazards and perils.
Hence, it becomes increasingly apparent that the longevity and prosperity of these majestic migratory birds are closely intertwined with the preservation and sustainable management of their invaluable food source – the horseshoe crabs.
Ensuring an adequate fuel supply for these birds during their extensive and arduous journey is of utmost importance, emphasized Kraft.
The interdependence between horseshoe crabs and the survival of the red knot in the forthcoming years is undeniably evident. The red knot, a migratory bird species, relies heavily on the eggs of horseshoe crabs as a vital food source during their long-distance migrations.
These small, red-breasted birds undertake an astonishing feat, traveling thousands of miles each year from their breeding grounds in the Arctic to their wintering grounds in South America.
The timing of their arrival at the Delaware Bay, a crucial stopover site, coincides with the peak spawning season of horseshoe crabs. This synchrony between the red knot and horseshoe crabs is essential for the birds’ survival, as they need to replenish their energy reserves before continuing their journey.
The eggs of horseshoe crabs provide a rich and nutritious fuel source that enables the red knots to complete their migration successfully.
Therefore, the conservation and protection of horseshoe crabs are vital to ensure the continued survival of the red knot population. The significance of this relationship cannot be overstated, as any disruption or decline in the horseshoe crab population would have dire consequences for the red knots and their ability to complete their epic migratory journey.
Thus, it is imperative that measures are taken to safeguard the horseshoe crab population and preserve their critical role in sustaining the red knot species in the years to come.
The horseshoe crabs hold immense value due to their unique ability to provide a crucial component in the manufacturing of limulus amebocyte lysate, commonly known as LAL.
This substance is instrumental in detecting pathogens present in vital medications like injectable antibiotics. To obtain this valuable resource, fishermen meticulously collect the horseshoe crabs either by hand or through trawlers, ensuring their availability for biomedical companies.
Once captured, the crabs’ blood is carefully separated, and the proteins within their white blood cells are processed.
It is worth noting that the blood of numerous crabs is required to fill a single glass tube, as it contains immune cells that possess a remarkable sensitivity to bacteria.
On the East Coast, there are only five federally licensed manufacturers responsible for processing horseshoe crab blood.
Activist groups often describe the blood as being worth an astounding $15,000 per quart (liter); however, industry experts argue that this figure is challenging to substantiate.
Nevertheless, the scarcity and importance of this resource contribute to its perceived high value.
Unfortunately, the bleeding process of horseshoe crabs does come at a cost. Regulators estimate that approximately 15% of the crabs perish during this procedure.
In 2021 alone, this amounted to the loss of around 112,000 crabs, according to Caitlin Starks, a senior fishery management plan coordinator at the Atlantic States Marine Fisheries Commission.
It is disheartening to note that the bait fishery for horseshoe crabs, primarily utilized as bait for eels and sea snails, resulted in the deaths of over six times that number.
The delicate balance between the necessity of horseshoe crab blood for medical advancements and the ethical concerns surrounding its extraction presents a complex dilemma.
As the demand for indispensable medicines continues to rise, it becomes imperative to explore alternative methods of obtaining LAL while ensuring the conservation and preservation of this remarkable species.
In a recent development, the fisheries commission has taken a significant step by approving new best management practices for the biomedical industry’s harvesting and handling of crabs.
This decision comes as a response to the growing concerns regarding the impact of sunlight exposure and inadequate moisture on the well-being of these crustaceans.
By minimizing their exposure to sunlight and ensuring that they are kept cool and moist, the commission aims to address the welfare issues associated with the harvesting and handling process.
This move reflects a commitment to upholding ethical standards and promoting sustainable practices within the biomedical industry.
It is a positive stride towards safeguarding the welfare of these creatures and ensuring their optimal conditions are maintained throughout the harvesting and handling stages.
Such proactive measures demonstrate the commission’s dedication to responsible management and the preservation of marine resources.
The statement, “The goal is to give the crabs that are bled a better chance of surviving and contributing to the ecosystem after they are released,” reflects an important aspect of the newly introduced guidelines.
Nora Blair, the quality operations manager at Charles River Laboratories, a prominent manufacturer of Limulus Amebocyte Lysate (LAL) derived from horseshoe crab blood, affirms that these guidelines will precisely achieve this objective.
Blair’s involvement as a member of the working group responsible for formulating these updated guidelines demonstrates the collaborative effort between industry professionals, conservationists, fishery managers, fishermen, and other stakeholders.
This diverse representation ensures that the guidelines encompass a comprehensive perspective, taking into account the interests and concerns of all parties involved.
By prioritizing the survival and contribution of bled crabs to the ecosystem, these guidelines not only address ethical considerations but also promote the overall sustainability of the horseshoe crab population and the ecosystems they inhabit.
Blair has stated that the industry is actively working towards developing a synthetic alternative to horseshoe crabs, a goal that conservationists have been advocating for over the years.
However, at present, the wild harvest of horseshoe crabs remains of utmost importance for ensuring drug safety, as emphasized by Blair.
He further asserts that due to their critical role in the biopharmaceutical supply chain and coastal ecosystem, the conservation of horseshoe crabs is imperative. The Atlantic horseshoe crab, which is harvested along the East Coast, spans from the Gulf of Maine to Florida.
According to the 2016 assessment conducted by the International Union for Conservation of Nature, this species is classified as “vulnerable.” The Delaware Bay, an estuary located between Delaware and New Jersey, is particularly significant for horseshoe crabs as it serves as their breeding ground and a feeding area for red knots.
According to Lawrence Niles, an esteemed independent wildlife biologist and former head of New Jersey’s state endangered species program, the density of horseshoe crab eggs in the bay is significantly lower than it was in the 1990s.
In addition, the rufa red knot, a subspecies that is currently threatened, has experienced a staggering 75% decline since the 1980s, as reported by the National Park Service.
To facilitate the recovery of these birds, Niles emphasizes the need for substantial protection of horseshoe crab eggs. His extensive experience in monitoring the health of red knots and horseshoe crabs has led him to establish the Horseshoe Crab Recovery Coalition, a group dedicated to advocating for conservation measures.
Niles and the volunteers he organizes have been diligently counting horseshoe crab eggs since the 1980s, as well as tagging birds since the 1990s.
As he concluded this year’s tracking activities in southern New Jersey in mid-June, Niles described the egg count as consistently positive throughout the month. His ultimate goal is to cease the harvest and killing of horseshoe crabs, allowing their population to rebuild to its maximum capacity.
Over the years, horseshoe crabs have been extensively harvested for bait and medicinal purposes, with the largest harvests occurring in Maryland, Delaware, Massachusetts, and Virginia. Federal fishery statistics indicate that the crabs were valued at approximately $1.1 million at the docks in 2021.
The economic value of certain seafood species, such as lobsters and scallops, far surpasses that of horseshoe crabs, often reaching hundreds of millions of dollars.
Nevertheless, it is important to acknowledge the dedicated efforts of horseshoe crab fishers who serve as stewards of a fishery that provides an essential product. George Topping, a fisherman from Maryland, emphasizes the significance of horseshoe crab blood in various aspects of life.
From vaccines to antibiotics, the utilization of horseshoe crab blood is pervasive. Topping further asserts that the stocks of horseshoe crabs remain robust and healthy.
This underscores the importance of recognizing the value of horseshoe crabs as a vital resource for the medical and pharmaceutical industries.
