Mastering Roe for Fraser River Sturgeon
For anglers dedicated to pursuing the legendary White Sturgeon of the Fraser River, the choice of bait is paramount. While many offerings can tempt these prehistoric giants, none hold the almost mythical status of salmon roe, especially when the river swells with migrating salmon. For Sturgeon BC readers looking to elevate their angling game, understanding the nuances of fishing with roe – from selection and preparation to presentation – can be the key to unlocking truly unforgettable encounters.
Why Roe Reigns: A Sturgeon’s Natural Delicacy
The Fraser River ecosystem is intricately linked with its massive salmon runs. As Chinook, Sockeye, Coho, Chum, and Pink salmon return to their natal streams to spawn, they create a veritable feast for resident sturgeon. These ancient bottom dwellers have evolved to capitalize on this seasonal bounty.
- Nature’s Signal: The scent of salmon and their eggs is a powerful dinner bell for sturgeon. It signals a readily available, high-energy food source.
- Nutritional Goldmine: Salmon eggs are packed with protein, fats, and essential nutrients, making them an incredibly efficient meal for sturgeon looking to build reserves.
- Scent Dispersion: Roe, whether loose or in bags, releases a potent and attractive scent trail that sturgeon, with their highly developed olfactory senses, can detect from considerable distances in the often-turbid Fraser waters.
While effective year-round if presented correctly, roe truly shines from late summer through the fall and into early winter, coinciding with the peak salmon spawning activities.
Understanding Your Options: Types of Salmon Roe
Not all salmon roe is created equal in the eyes of a sturgeon, though most will be readily accepted if fresh. The various Pacific salmon species frequenting the Fraser offer different roe characteristics:
- Chinook (King) Salmon Roe: Often large, rich, and oily. Highly prized, though Chinook runs have faced challenges.
- Sockeye Salmon Roe: Typically smaller, bright red eggs, known for their high oil content and strong scent. A favorite for many.
- Coho Salmon Roe: Medium-sized eggs, good color, and scent. Widely available during Coho runs.
- Chum Salmon Roe: Larger individual eggs, often a paler orange. Chum roe is very popular due to the egg size, making for robust bait bags, and its strong scent. Many veteran sturgeon anglers swear by fresh Chum roe.
- Pink Salmon Roe: Smaller eggs, but plentiful during Pink salmon years (which are typically odd-numbered years in the Fraser). Can be very effective due to sheer abundance.
Freshness is paramount regardless of the species. Good quality roe will be plump, relatively firm, and have a clean, fishy smell, not a rancid or overly ammonia-like odor.
Sourcing and Storing Your Roe
- Local Tackle Shops: During salmon season, many Fraser Valley tackle shops carry fresh or well-preserved frozen salmon roe (skeins or loose eggs). They are an excellent source and can offer advice on what’s currently working.
- From Your Catch (Where Permitted): If you are legally and ethically harvesting salmon, their roe can be an excellent source. Ensure you are familiar with all DFO regulations regarding salmon retention and bait use.
- Storage: Fresh roe is delicate. Keep it chilled on ice (not submerged in meltwater) until ready to process or use. For longer-term storage, roe can be cured and then refrigerated or frozen. If freezing, vacuum-sealing in small portions is ideal to prevent freezer burn and maintain quality. Thaw slowly in the refrigerator.
The Art of Curing: Enhancing Your Offering (Optional but Often Beneficial)
While fresh, uncured roe is a fantastic natural bait, curing can offer several advantages:
- Toughens Eggs: Cured eggs become firmer, making them more durable on the hook and better able to withstand casting and the attention of smaller bait-stealing fish.
- Enhances Scent: Certain cure ingredients can amplify or modify the scent profile.
- Preservation: Curing extends the lifespan of the roe, allowing you to store it for longer periods.
- Color Modification: Dyes can be added to change or enhance the color, which some anglers believe makes a difference in certain water conditions.
Common Curing Approaches:
- Simple Borax Cure: The most common and straightforward method. Lay out skeins or loose eggs on paper towels, generously sprinkle with plain Borax (20 Mule Team Borax is a classic), ensuring all surfaces are coated. Let them air dry in a cool place for several hours or overnight until they reach the desired firmness. Borax draws out moisture and toughens the eggs.
- Sugar/Salt/Borax Mixes: Many anglers develop their own recipes. A common starting point is a 3-2-1 ratio (3 parts Borax, 2 parts sugar, 1 part non-iodized salt). These ingredients are mixed and applied similarly to a plain Borax cure. Sugar is believed to be an attractant.
- Commercial Cures: Numerous excellent commercial cures are available (e.g., Pro-Cure, Pautzke Bait Co. products) that come with specific instructions. These often contain a blend of salts, sugars, coloring agents, and scent enhancers.
- Scent Additives (Use with Caution): Some anglers add small amounts of anise oil, shrimp oil, krill powder, or other fish-attracting scents to their cures. However, it’s crucial to remember that sturgeon have an incredibly keen sense of smell and can be put off by unnatural or overly strong chemical scents. Natural is often best.
A Note on Curing for Sturgeon vs. Salmon/Trout: While salmon and trout anglers often use bright, heavily scented cures, sturgeon generally prefer a more natural presentation. Avoid overly chemical or artificial smelling cures. Some guides even prefer completely uncured, fresh roe if available, believing it to be the most natural offering.
Rigging Roe: The Classic Spawn Sack
For sturgeon fishing, the most effective way to present roe is in a spawn sack (roe bag). This keeps the delicate eggs contained, allows for a good hook hold, and enables the scent to “milk” out into the current.
Materials:
- Spawn Netting: Available in various colors (red, pink, orange, chartreuse, white). Experiment with colors, as sometimes one produces better than others, though scent is the primary driver.
- Bait Thread (Spider Thread/Magic Thread): Elasticated thread that sticks to itself, making it easy to tie off sacks.
- Quality Roe: Fresh or cured.
Tying a Roe Bag:
- Cut a square of spawn netting (typically 3×3 to 5×5 inches, depending on desired sack size).
- Place a cluster of roe (or a chunk of skein) in the center. The amount can vary from the size of a large marble to a golf ball, or even slightly larger for Chum roe. Don’t pack it too loosely, or it will wash out quickly; don’t pack it rock-hard, or it won’t milk as well.
- Gather the corners of the netting, forming a pouch.
- Twist the top of the pouch tightly.
- Secure the twisted neck by wrapping it tightly several times with bait thread. The thread will stick to itself.
- Trim off the excess netting above the thread.
Hooking: Pass your hook (typically a 5/0 to 10/0 barbless circle or octopus hook) through the mesh of the tied-off “neck” of the roe bag. Ensure the hook point is well exposed for a solid hookset.
Presentation Tactics for Roe
- Bottom Delivery: Sturgeon are bottom feeders. Your roe bag must be presented directly on the riverbed. Use a sliding sinker rig with enough weight (8-24+ ounces, depending on current and depth) to hold bottom effectively.
- Leader Length: A leader of 18-36 inches is typical. This allows the roe bag some natural movement near the bottom.
- Scent Dispersal: The gentle current flowing past the roe bag will carry its scent downstream, creating a trail for sturgeon to follow. Position yourself upstream of likely sturgeon holding areas.
- Casting: Roe bags, while fairly robust once tied, are still more delicate than some other baits. Use a smooth, lobbing cast rather than a powerful snap cast to prevent the bag from tearing off or bursting.
Prime Time and Location for Roe
- The Fall Feast: Roe is king from late August through November, during the peak of the Fraser’s diverse salmon runs. Sturgeon actively seek out this abundant food source.
- Post-Spawn: Even after the main spawning activity, sturgeon will continue to feed on remaining eggs and decaying salmon carcasses, making roe effective into the early winter.
- Location, Location, Location: Focus on areas downstream of known salmon spawning grounds. Eddies, seams where fast and slow water meet, and deeper holes adjacent to spawning gravel are prime spots. Sturgeon will hold in these areas, waiting for eggs to drift by.
Pro Tips for Roe Success
- Fresh is Best: Even with cured roe, try to use the freshest possible. If your roe bags look washed out or have lost their scent, re-bait.
- Scent Control: Minimize human or unnatural scents on your bait. Wash hands thoroughly, or consider using gloves when handling roe and tying sacks.
- Experiment: Don’t be afraid to try different types of salmon roe, variations in your cure, different spawn netting colors, and various sack sizes.
- Patience Pays: While roe is a top-tier bait, sturgeon fishing demands patience. Let your bait soak and do its job.
- Check Your Bait: Periodically check your roe bag, especially if smaller fish (like pike minnows) are active, as they can peck away at it. A typical soak time might be 30-60 minutes before re-baiting if there’s no action, but this can vary greatly.
Ethical Angling with Roe
- Responsible Sourcing: Always obtain your roe legally and ethically.
- Clean Up: Dispose of used spawn netting, bait thread, and any leftover bait properly. Pack it out with you.
- Adhere to Regulations: Be fully aware of all current fishing regulations, including those pertaining to salmon and sturgeon.
The Allure of the Egg
For the dedicated Fraser River sturgeon angler, mastering the use of salmon roe is a rite of passage. It’s a bait that connects directly to the river’s ancient cycles and the sturgeon’s natural instincts.
