As someone who’s spent over a decade exploring the coastlines of the United States, from the Pacific Northwest to the Atlantic shores, I’ve seen a lot. But even I was surprised the first time I came across a sturgeon washed up on the beach. These prehistoric-looking fish, often called “dinosaur fish” due to their ancient lineage, are a magnificent sight in the water, but finding one deceased on shore can be unsettling. Knowing what to do – and not do – is crucial, both for legal reasons and for the potential conservation of these incredible creatures. This guide will walk you through everything you need to know when you encounter a dinosaur fish washes up, covering identification, reporting, and responsible handling.
Identifying a Sturgeon: Is it Really a “Dinosaur Fish”?
The term “dinosaur fish” is a popular nickname for sturgeon, and it’s not entirely inaccurate. Sturgeon are ancient fish, with fossil records dating back over 200 million years – predating even the dinosaurs! There are several species of sturgeon found in North American waters, including the Atlantic sturgeon, White sturgeon, and Green sturgeon. Here’s how to identify them:
- Appearance: Sturgeon have elongated bodies covered in bony plates called scutes, rather than scales. They have a distinctive shovel-shaped snout and a heterocercal tail (where the upper lobe is larger than the lower lobe).
- Size: Sturgeon can grow to impressive sizes. White sturgeon, found in the Pacific Northwest, are the largest freshwater fish in North America, reaching lengths of over 10 feet and weights exceeding 800 pounds. Atlantic sturgeon are typically smaller, but can still reach 8-10 feet.
- Coloration: Color varies by species and age, ranging from olive-brown to gray to almost black.
- Barbels: Look for four barbels (whisker-like sensory organs) near their mouth. These help them locate food on the bottom of rivers and estuaries.
If you’re unsure if the fish you’ve found is a sturgeon, take clear photos and compare them to images online. The NOAA Fisheries website has excellent species identification guides. Misidentification can lead to incorrect reporting and potentially hinder conservation efforts.
What to Do When You Discover a Washed-Up Sturgeon
Finding a sturgeon washed up on beach can be a distressing experience. Here’s a step-by-step guide on how to respond:
- Observe from a Distance: Do not immediately approach or attempt to move the sturgeon. Even a dead sturgeon can have sharp scutes and a powerful tail.
- Document the Location: Precisely note the location using GPS coordinates if possible. Include details about the beach, landmarks, and any nearby structures.
- Take Photographs: Capture clear photos of the entire sturgeon, including close-ups of its head, body, and any visible injuries. Photos are crucial for identification and reporting.
- Report the Finding: This is the most important step. Who you report to depends on the location and species.
- Atlantic Sturgeon: Report to the NOAA Fisheries Office of Law Enforcement.
- Pacific Sturgeon (White & Green): Contact your state’s Department of Fish and Wildlife. (e.g., Washington Department of Fish and Wildlife, Oregon Department of Fish and Wildlife).
- General Reporting: You can also contact the local National Park Service (nps.gov) or USDA Forest Service (fs.usda.gov) if the sturgeon is found within their jurisdiction.
- Follow Instructions: The agency you contact will provide specific instructions. They may ask you to remain at the location until a biologist arrives, or they may instruct you to leave the sturgeon undisturbed.
Legal Considerations: Why Reporting is Essential
Sturgeon are protected under federal and state laws. Many species are listed as threatened or endangered, and even handling a dead sturgeon without authorization can be illegal. Here’s why reporting is so important:
- Endangered Species Act: Atlantic, White, and Green sturgeon are all protected under the Endangered Species Act. Disturbing or harming these species can result in significant fines and penalties.
- State Regulations: Most states have specific regulations regarding sturgeon, including restrictions on harvesting, possession, and reporting of dead specimens.
- Data Collection: Reporting helps scientists track sturgeon populations, identify threats, and develop effective conservation strategies. Information gathered from stranded sturgeon can provide valuable insights into their health, diet, and migration patterns.
- Potential for Investigation: In some cases, a sturgeon washed up on the beach may be the result of illegal poaching or other harmful activities. Reporting the finding can trigger an investigation.
What Not to Do: Avoiding Harmful Actions
It’s just as important to know what not to do when you find a dinosaur fish washes up. Here are some actions to avoid:
- Do Not Attempt to Move the Sturgeon: As mentioned earlier, even a dead sturgeon can be dangerous.
- Do Not Remove Any Parts of the Sturgeon: Removing scutes, eggs, or other parts of the fish is illegal and can hinder scientific analysis.
- Do Not Attempt to Bury the Sturgeon: Leave the disposal to the authorities. They may want to collect tissue samples for analysis.
- Do Not Post the Location Widely on Social Media: While sharing information is good, publicly broadcasting the exact location can attract poachers or individuals who may disturb the site.
Why are Sturgeon Washing Ashore? Understanding the Causes
There are several reasons why you might find a sturgeon washed up on beach. Understanding these causes can help us better protect these vulnerable fish:
- Natural Causes: Old age, disease, and predation can all contribute to sturgeon mortality.
- Ship Strikes: Sturgeon are often found in busy shipping lanes, and collisions with vessels can cause serious injuries or death.
- Habitat Degradation: Pollution, dam construction, and other forms of habitat degradation can negatively impact sturgeon populations.
- Climate Change: Changes in water temperature and salinity can stress sturgeon and make them more susceptible to disease.
- Illegal Poaching: Although illegal, poaching continues to be a threat to sturgeon populations, particularly for their valuable eggs (caviar).
Supporting Sturgeon Conservation Efforts
As outdoor enthusiasts, we all have a role to play in protecting sturgeon. Here are some ways you can help:
- Report Sightings: Continue to report any sturgeon sightings, both live and dead, to the appropriate authorities.
- Support Conservation Organizations: Donate to organizations dedicated to sturgeon conservation, such as the Sturgeon Recovery.
- Practice Responsible Boating: Be aware of sturgeon habitat and slow down in areas where they are known to congregate.
- Reduce Your Environmental Impact: Minimize your use of pollutants and support sustainable practices that protect water quality.
- Educate Others: Share your knowledge about sturgeon with friends, family, and fellow outdoor enthusiasts.
Encountering a sturgeon washed up on the beach is a sobering reminder of the challenges facing these ancient creatures. By following the guidelines outlined in this article, you can help ensure that future generations have the opportunity to witness the majesty of these “dinosaur fish” in their natural habitat. Remember, responsible reporting and conservation efforts are key to their survival. As a seasoned outdoor professional, I encourage everyone to be a steward of our natural resources and protect these incredible animals.
