How to Find Long Beach Spot Prawns

Long Beach spot prawns, scientifically known as Pandalus platyceros, are a prized delicacy along the Pacific coast of North America. Renowned for their sweet, delicate flavor and firm, succulent texture, these crustaceans are highly sought after by seafood enthusiasts, chefs, and commercial harvesters alike. Found primarily in the cold, clean waters from Alaska to Baja California, spot prawns are particularly abundant in the coastal regions surrounding Long Beach, California, where tidal conditions, underwater topography, and seasonal migrations create ideal habitats.

Finding Long Beach spot prawns is not merely a matter of casting a net into the ocean—it requires a deep understanding of marine biology, local regulations, seasonal patterns, and the right tools and techniques. Whether you're a recreational fisher, a commercial harvester, or a curious foodie seeking to source these prawns sustainably, knowing how and where to locate them is essential. This guide provides a comprehensive, step-by-step roadmap to help you successfully find Long Beach spot prawns, while emphasizing ethical practices, legal compliance, and environmental stewardship.

Step-by-Step Guide

Understand the Species and Habitat

Before you begin searching, it’s crucial to understand the biology and behavior of spot prawns. These shrimp-like crustaceans live in deep, rocky reef environments, typically between 100 and 500 feet below the surface. They prefer areas with strong currents and abundant cover such as boulders, kelp beds, and submerged ledges. In the Long Beach area, the best habitats are found off the Palos Verdes Peninsula, near the Newport Canyon, and along the offshore reefs of the Santa Monica Bay.

Spot prawns are nocturnal and tend to emerge from their crevices at dusk to feed. They are most active during the spring and early summer months, particularly from April through July, when water temperatures range between 52°F and 60°F. During this window, spawning activity peaks, and prawns migrate toward shallower waters, making them more accessible to trawlers and divers.

Check Local Regulations and Licensing

California’s Department of Fish and Wildlife (CDFW) strictly regulates the harvest of spot prawns. Recreational fishermen must possess a valid California sport fishing license. Commercial harvesters require additional permits, including a Commercial Fishing License and a Spot Prawn Endorsement. Failure to comply can result in significant fines and confiscation of equipment.

There are seasonal closures, gear restrictions, and daily bag limits. As of the latest regulations, recreational fishers are limited to 35 spot prawns per day, and only trap or dip net gear is permitted—trawling is prohibited in nearshore zones. Always verify the current rules on the CDFW website before heading out, as regulations can change annually based on stock assessments.

Choose the Right Time of Year

Timing is everything when it comes to finding spot prawns. The peak season in the Long Beach region typically begins in late April, with the highest concentrations appearing in May and early June. Water temperature and lunar cycles play a significant role: prawns are more active during high tides and in the days following a full moon.

Winter months (December–March) are generally too cold, and prawns retreat to deeper waters. Late summer (August–September) sees a decline in abundance as prawns begin to spawn and migrate offshore. Plan your excursions during the prime window to maximize your chances of success.

Select Appropriate Gear

For recreational anglers, the most effective tools are spot prawn traps and dip nets. Prawn traps are wire cages with funnel entrances that allow prawns to enter but make escape difficult. They are baited with fish scraps, squid, or shrimp heads and lowered to the seafloor. Dip nets, typically 3–4 feet in diameter with a long handle, are used by divers or from piers to scoop prawns from crevices.

Commercial harvesters use larger, standardized traps called “spot prawn pots,” which are deployed in rows and marked with surface buoys. These pots are designed to minimize bycatch and are often equipped with escape vents for undersized or non-target species.

Regardless of method, always use gear that complies with state regulations. Avoid using hooks, lines, or trawl nets, which are illegal for spot prawn harvest in California’s nearshore waters.

Locate Prime Fishing Zones

The most productive areas for finding Long Beach spot prawns include:

• Palos Verdes Reef Complex – A network of submerged rock formations extending 2–3 miles offshore, ideal for trap placement.
• Point Fermin to Point Vicente – Rocky outcrops and deep channels where prawns congregate during migration.
• Offshore of Alamitos Bay – Sandy bottoms adjacent to kelp forests provide transitional habitat.
• The Newport Canyon Edge – A steep drop-off zone where deep-water prawns move toward shallower feeding grounds.

Use nautical charts and GPS mapping tools to pinpoint these areas. Look for depth contours between 150 and 300 feet, and avoid areas with strong surface currents that may interfere with trap stability. Local marinas and fishing supply stores often have updated maps and advice from experienced captains.

Deploy Traps Correctly

When deploying traps, follow these best practices:

1. Attach a heavy sinker (5–10 lbs) to ensure the trap stays on the bottom.
2. Bait the trap with fresh, oily fish like mackerel or sardines—avoid processed or frozen bait that may leak too quickly.
3. Lower the trap slowly to avoid disturbing the sediment or scaring off prawns.
4. Mark your trap location with a bright, floating buoy. Use a unique color or identifier to avoid confusion with other fishers’ gear.
5. Check traps every 4–6 hours. Spot prawns are highly mobile and may escape if left too long, especially in warm water.

Never leave traps unattended overnight unless permitted by law. Many areas require daily retrieval to prevent ghost fishing and marine debris.

Use Underwater Technology

Modern technology can significantly enhance your ability to locate prawns. Portable underwater cameras, such as the GoPro HERO with a waterproof housing, can be attached to a line and lowered to scout for prawn activity. Look for movement near rocks or within kelp fronds—spot prawns are often visible as translucent, reddish-brown creatures with distinctive white spots on their backs.

Side-scan sonar and fish finders with bottom mapping capabilities can help identify structure-rich zones where prawns are likely to hide. Devices like the Humminbird Helix 7 or Lowrance HDS Live can detect hard-bottom areas and rock piles, which are prime prawn habitats.

Some commercial operators use remotely operated vehicles (ROVs) equipped with high-definition cameras and lights to survey deeper zones. While expensive, these tools are invaluable for locating prawns in waters beyond diving depth.

Work with Local Knowledge

No guidebook can replace firsthand experience. Connect with local fishermen, dive clubs, and charter captains who operate in the Long Beach area. Many have been harvesting spot prawns for decades and can share insights on recent hotspots, weather patterns, and prawn behavior.

Join online forums such as California Fishing Forum or Reddit’s r/CaliforniaFishing. Attend monthly meetings at the Long Beach Fishing Club or visit bait shops like Fisherman’s Market in Seal Beach. These are rich sources of real-time intelligence on prawn movements and successful techniques.

Record and Analyze Your Success

Keep a detailed log of each outing: date, time, water temperature, tide phase, depth, location (GPS coordinates), bait used, number of prawns caught, and environmental conditions. Over time, patterns will emerge—perhaps you consistently catch more prawns on rising tides after a cold front, or near specific rock formations at 220 feet.

Use this data to refine your strategy. Digital tools like Google Sheets or specialized fishing apps (e.g., FishAngler or AnglerLog) can help you visualize trends and predict optimal fishing windows.

Best Practices

Practice Sustainable Harvesting

Spot prawns are a vulnerable species due to their slow growth and late maturity (they can live up to 8 years). Overharvesting can lead to population collapse, as seen in other regions with unregulated fisheries. To ensure long-term availability:

• Release undersized prawns (under 3 inches) immediately and gently.
• Avoid harvesting during spawning season (late summer).
• Do not take more than your legal limit.
• Use gear that minimizes habitat disruption—avoid dragging traps across sensitive reefs.

Support initiatives like the Marine Stewardship Council (MSC) certification for spot prawn fisheries. Choosing certified products helps incentivize sustainable practices across the industry.

Respect Marine Protected Areas (MPAs)

California has established numerous MPAs along the coast, including the Point Vicente MPA and the Palos Verdes Peninsula MPA, where all fishing—including spot prawn harvesting—is prohibited. These zones serve as critical sanctuaries for marine life to recover and reproduce. Always consult the CDFW’s MPA map before heading out. Violating these boundaries not only harms ecosystems but also risks legal penalties.

Minimize Environmental Impact

Never leave bait containers, plastic packaging, or lost gear in the ocean. Use biodegradable bait bags and dispose of waste properly on shore. Avoid anchoring on coral or kelp beds—use mooring buoys where available. Spot prawns depend on healthy kelp forests for shelter and food; damaging these habitats indirectly reduces their population.

Handle Prawns Humanely

Once caught, spot prawns should be kept alive in a well-aerated, cool container with seawater. Avoid overcrowding. If you plan to keep them for consumption, humanely dispatch them by placing them in a saltwater ice slurry immediately after capture. This reduces stress and preserves meat quality.

Stay Informed About Ocean Conditions

Environmental factors like El Niño, ocean acidification, and marine heatwaves can drastically alter prawn distribution. Monitor resources like NOAA’s Ocean Observations, the California Current Assessment, and local buoy data from the Southern California Coastal Ocean Observing System (SCCOOS). These platforms provide real-time data on temperature, salinity, and current speed—all critical for predicting prawn behavior.

Engage in Citizen Science

Participate in programs like the CDFW’s “Report Your Catch” initiative or the Scripps Institution of Oceanography’s coastal monitoring projects. Reporting your catch data—even if you catch none—helps scientists track population trends and adjust management policies. Your contributions can directly influence conservation outcomes.

Real Examples

Case Study 1: Recreational Fisherman in Long Beach

In May 2023, a retired fisherman named Miguel used a combination of GPS mapping and underwater camera footage to locate a previously unexplored reef 1.8 miles off the coast of Alamitos Bay. He deployed five traps baited with fresh squid and checked them every five hours. Over two days, he caught 32 spot prawns—within his legal limit. His logs revealed that the highest catch occurred during rising tides with water temperatures of 57°F. He shared his findings with the local fishing club, which led to a new hotspot being added to community maps.

Case Study 2: Commercial Harvester Using Sustainable Methods

A small-scale commercial operator in San Pedro began using MSC-certified spot prawn pots in 2022. He reduced the number of traps by 40%, increased retrieval frequency to every 4 hours, and installed escape vents to release juvenile prawns. In 2023, his catch volume remained stable, but bycatch dropped by 70%, and his gear damage decreased due to less seabed abrasion. He now markets his prawns as “sustainably harvested Long Beach spot prawns” and sells directly to high-end restaurants in Los Angeles.

Case Study 3: Citizen Scientist Contribution

A marine biology student at CSU Long Beach participated in a CDFW citizen science project, recording 112 spot prawn sightings from her dives between April and June. Her data showed that prawns were significantly more abundant in areas with dense giant kelp coverage than in bare sand zones. Her findings were included in the state’s 2024 stock assessment, leading to expanded protection for kelp forests in the Santa Monica Bay.

Case Study 4: Failed Attempt and Lessons Learned

In June 2022, a group of recreational fishers ignored tide charts and deployed traps during a strong ebb current. The traps were dragged across the seafloor, damaging coral and kelp. They caught only 4 prawns and lost 3 traps. After consulting with a local captain, they learned that traps must be placed during slack tide and anchored securely. In 2023, they returned with proper gear and timing, catching 28 prawns with zero gear loss.

FAQs

Where are the best spots to find Long Beach spot prawns?

The most reliable locations are the Palos Verdes Reef Complex, the Newport Canyon edge, and the rocky zones between Point Fermin and Point Vicente. These areas provide the deep, structured habitats spot prawns prefer.

What’s the best time of day to catch spot prawns?

Spot prawns are most active at dusk and during the night. However, traps can be checked during daylight hours. The best time to deploy traps is early morning or late afternoon, allowing them to settle before peak activity at twilight.

Can I use a fishing pole to catch spot prawns?

No. Hook-and-line fishing is not permitted for spot prawns in California. Only traps and dip nets are legal. Using a fishing pole may result in fines and equipment confiscation.

How do I know if a prawn is legal to keep?

Legal spot prawns must be at least 3 inches in total length (from the eye to the end of the tail). They should also have the characteristic white spots on their backs and a firm, translucent body. Juveniles are often smaller, softer, and lack distinct spotting.
