How to Set Crab Traps in BC: A Beginner's Step-by-Step Guide

Knowing how to set crab traps comes down to three things: the right spot, the right depth and the right soak time. In BC, set your trap in 10–30 m of water over a muddy or sandy bottom near eelgrass. Bait it, attach a buoy marked with your name, drop it, and check it after a couple of hours.

This guide walks you through every step. If you're still choosing gear, start with our range of crab and prawn traps.

Key Takeaways

•         Set traps in 10–30 m of water over mud or sand, close to eelgrass.

•         Use a marked buoy and enough line to reach the bottom at high tide, plus spare.

•         Check your trap after one to two hours, and measure every crab right away.

•         You need a Tidal Waters Sport Fishing Licence, and you can use a maximum of two traps.

•         Check DFO for closures and limits before every trip. Rules change.

What You Need Before You Go Crabbing

A good first trip starts on shore. Gather your gear and check your paperwork before you leave the dock.

Here's a simple checklist:

•         A crab trap or ring in good working order

•         Fresh bait and a bait cage or bait jar

•         A buoy marked with your name

•         Buoy line, plus a weight if your trap needs one

•         A crab gauge, gloves and a bucket

•         A lifejacket for everyone on board

•         Your Tidal Waters Sport Fishing Licence

Your buoy line matters more than most beginners expect. Floating line drifts on the surface and can wrap around your propeller. Most crabbers use sinking rope for the main line so it stays down and out of the way.

Pick a line long enough to reach the bottom at high tide. Add some spare so your buoy doesn't get pulled under when the current runs.

Where to Set Crab Traps in BC

Dungeness crab prefer muddy or sandy bottoms near eelgrass beds. That's your starting point.

Around the Strait of Georgia and the Fraser River approaches, look for sandy flats and gentle drop-offs with eelgrass nearby. A chart or fishfinder helps you read the bottom before you drop anything.

A few places to avoid:

•         Navigation channels. Traps must not be set where boats travel. Stay clear of marina entrances and ferry lanes.

•         Closed areas. Some areas are closed for conservation or contamination. Check DFO's current closures before you go.

•         Very strong current. Fast water drags traps and buoys around. Look for calmer pockets.

Step-by-Step: How to Set Crab Traps (Baiting, Dropping and Marking)

Once you've found your spot, the process is simple. Take your time on your first few drops.

1.       Check your trap. Make sure the openings work and the escape section is intact. DFO requires an escape opening in recreational traps.

2.       Attach your marked buoy. Write your name on the buoy. DFO can remove gear that isn't marked.

3.       Bait the trap. Put fresh bait in a bait cage or jar and secure it in the centre of the trap so crabs can't pull it out.

4.       Tie on the line. Secure the buoy line to the trap with a strong knot. Coil the line neatly in the boat so it pays out without tangling.

5.       Slow down and lower the trap. Don't throw it. Lower it over the side and let the line run out freely, keeping your feet clear of the coils.

6.       Drop the buoy last. Make sure it floats upright and the line isn't wrapped around anything.

7.       Note your position. Mark it on your GPS or use landmarks, and write down the time you set the trap.

Keep your crab gauge, gloves and other fishing tools together in one bucket. When it's time to pull the trap, everything is within reach.

How Long to Soak and How to Pull Traps

Most boaters soak their traps for one to two hours. If the crabs are slow, you can leave them longer. Don't leave them so long that your bait is stripped.

Strong currents can drag traps and carry bait scent away. Many crabbers set their traps around slack tide for this reason.

To pull a trap:

1.       Approach the buoy slowly, with the current behind you if possible.

2.       Grab the line with a boat hook and bring it on board.

3.       Haul hand over hand and coil the line as you go.

4.       Lift the trap in and open it over a bucket or tote.

5.       Measure every crab right away. Release undersized crabs and all females quickly and gently.

6.       Rebait and reset, or bring the trap home.

Safety note: Wear your lifejacket when setting and hauling. A loose line around your foot can pull you overboard in seconds. If you're unsure about handling gear in rough water, go out with an experienced boater first.

BC Rules: Licences, Limits and Closed Areas

BC's crab rules protect the fishery, and fines for breaking them can be steep. Always check the official source. Here's a summary of what Fisheries and Oceans Canada (DFO) lists in its sport fishing guidelines for crab:

•         You need a valid Tidal Waters Sport Fishing Licence.

•         You may use a maximum of two crab traps or rings.

•         The daily limit for Dungeness or red rock crab is four on the South Coast and six on the North Coast. The possession limit is twice the daily limit.

•         Dungeness crab must measure at least 165 mm across the shell.

•         All female crab must be released.

•         Traps must be marked with your name, and must not be set in navigation channels.

Red rock crab have their own size limit, so check the DFO page for the current number. We cover measuring in more detail in a separate guide.

Rules, limits and closures change. Confirm the current details with DFO before you go.

Frequently Asked Questions

Do I need a licence to crab in BC?

Yes. You need a valid Tidal Waters Sport Fishing Licence to harvest crab in BC tidal waters. You can get one through DFO's online licensing system.

How long should crab traps soak?

One to two hours is a good starting point for most areas. If you aren't catching anything, move the trap to a new spot rather than waiting all day.

Can I leave crab traps overnight?

Some boaters do, but check DFO's current notices for your area first. Traps left for days can lose their buoy and become lost gear that keeps catching crab.
