Catching by hand during low tide
Catching crabs during low tide can be a productive endeavour, as it allows for easier access to crabs and their bait, triggering feeding frenzies. Here is a step-by-step guide for catching Asian shore crabs by hand during low tide:
Location Scouting:
Scout for locations with calm shorelines and shallow water, typically a few feet deep. Look for flat, sandy bottoms and shorelines, as crabs tend to favour sand, especially smaller, inshore species. Mangroves, bays, inlets, marshes, jetties, and piers are also prime spots to find crabs. Additionally, check for holes around shorelines and wet sand, as crabs like to hide in such structures.
Timing:
Time your crabbing excursion during low tide, specifically two hours before or after high tide, as this is when the tide becomes more slack, making it easier for crabs to move around. Low tide also provides a window to set up your equipment before the incoming tide brings crabs towards you.
Baiting:
Use chicken as bait, specifically chicken necks, which are a favourite among crabs. You can also experiment with other baits such as fish (especially oily fish like bunker), squid, turkey legs, or even small, strong-smelling pieces of meat.
Technique:
Use a hand line with a baited chicken neck and a dip net. Slowly pull the string closer to the shore, hand over hand, grabbing inches at a time. Stay patient, and when you see a crab nibbling on your chicken, quickly scoop it up from behind with your dip net. Crabs are fast swimmers, so you need to act swiftly.
Legal Considerations:
Check your local regulations regarding crabbing. While crabbing with a string may not require a recreational license, there might be restrictions on the number of hand lines allowed, minimum crab sizes, etc.
Remember to measure your catch to ensure it's of legal size. With these steps, you can successfully catch Asian shore crabs by hand during low tide, enjoying a fun and productive day by the shore.

Using a net to catch crabs attracted to bait
Asian shore crabs, or Hemigrapsus sanguineus, are an invasive species in North America and Europe. They are native to the coasts of East Asia, specifically Russia, Korea, China, and Japan. These crabs typically inhabit areas with large rocks, such as rocky shores and oyster reefs, and can also be found in salt marshes. They are known for their opportunistic omnivorous diet, consuming a variety of small invertebrates and favouring the consumption of animals over algae.
When it comes to using a net to catch crabs attracted to bait, there are a few methods that can be employed. Here is a step-by-step guide:
- Choose the right net: Select a small, collapsible drop net that can be easily transported and manoeuvred. A net with a fine mesh will help ensure that the crabs do not escape once they are trapped.
- Prepare the bait: Cut pieces of chicken or other bait, such as bunker or chick, can be used. Sand fleas are also mentioned as a bait option, which can be dug out from the sand during low tide.
- Find the right location: Asian shore crabs are often found in rocky areas, so look for boulders or jetties with crevices and cracks where the crabs can hide. The best time to catch them is during low light or at night, as they tend to come out from under the rocks more readily during these times.
- Set up the net: Attach the net to a stout rod or reel. Place the baited net in an area between rocks, ensuring that it is secure and hidden from plain sight. The net should be positioned in a spot where crabs are likely to pass by or congregate.
- Be patient: Wait for the crabs to be attracted to the bait and climb onto the net. This may take some time, so patience is key. During daylight, this method can still be successful but may require a quicker hand to capture the crabs before they scurry away.
- Reel in the net: Once you notice crabs on the net, quickly and carefully reel it up, bringing the crabs with it. You may need to do this swiftly to prevent the crabs from falling off or escaping.
- Empty and collect the crabs: After reeling in the net, carefully empty the crabs into a container or bucket. Repeat the process if necessary to catch more crabs.
Remember to handle the crabs with care and only harvest them from areas that are certified for crabbing or shellfishing, ensuring sustainability and adhering to any local regulations.

Using a collapsible net attached to a rod
Asian shore crabs, or Hemigrapsus sanguineus, are an invasive species in North America and Europe. They are native to the coasts of East Asia, including Russia, Korea, China, and Japan. These crabs typically inhabit areas with large rocks, such as rocky shores and oyster reefs, and can also be found in salt marshes. They are known for their opportunistic omnivorous diet, consuming a variety of small invertebrates and favouring the consumption of animals over algae.
When it comes to catching Asian shore crabs with chicken, one effective method is to use a collapsible net attached to a rod. Here is a step-by-step guide on how to do this:
- Attach a collapsible drop net to a sturdy rod or reel: Ensure that the rod is strong enough to hold the weight of the net and any crabs that you catch.
- Bait the net: Place a piece of chicken or other bait, such as bunker or chick, in the centre of the net. You can also try using sand fleas as bait, which can be found in the sand of the ocean surf during low tide.
- Find a suitable location: Look for areas where Asian shore crabs are known to congregate, such as rocky shores or areas with large boulders. They tend to come out in low light or at night, so plan your crabbing activity accordingly.
- Position the baited net: Place the baited net in a spot between rocks that is wide enough to accommodate it. Choose a location where the crabs are likely to move around and search for food.
- Wait patiently: It may take some time for the crabs to discover the bait and climb onto the net. Remain quiet and still to avoid scaring them away.
- Reel in the net: Once you see crabs on the net, quickly and carefully reel it up using the rod. Be prepared for the crabs to try to scurry away, so a swift and decisive action is key.
- Empty and collect the crabs: Once you have reeled in the net, carefully empty it out and collect the crabs that have been trapped. Place them in a secure container or bucket to transport them.
Remember to follow local regulations and guidelines for crabbing and only harvest crabs in areas that are certified for shellfishing or crabbing. Always handle the crabs with care and respect, and release any crabs that you do not intend to keep.

Digging coffee cans into the sand to trap crabs
To begin, find an area where the sand stays moist during low tide, as this is where Asian shore crabs tend to congregate. Dig several coffee cans into the sand, ensuring that they are flush with the top of the sand. The crabs will then fall into the cans as they move around.
It is important to note that this method may not work for all types of crabs and is specifically targeted towards Asian shore crabs. These crabs are known to inhabit rocky shores and craggy areas of the coast, so finding a sandy spot nearby will increase your chances of success.
Additionally, it is recommended to perform crabbing activities in areas that are certified for shellfishing. This ensures that the location is safe and clean for harvesting crustaceans.
By following these steps and choosing the right location, you can effectively trap Asian shore crabs using coffee cans dug into the sand. Remember to be patient and persistent, as crabbing requires time and a careful eye for the best spots.

Using a sand flea as bait
Sand fleas, also known as sand crabs or mole crabs, are small crustaceans that make excellent bait for surf fishing. They are commonly found on sandy beaches on both the West and East Coasts, where they bury themselves in the sand with just their antennae protruding, waiting for plankton to wash over them as the waves move in and out.
To use sand fleas as bait, you'll first need to gather a bunch of them. You can do this with your hands, a sand shovel, or a sand rake, or by using a net. Simply kick the sand to loosen it and let the tide sweep the dislodged sand fleas into the net.
Once you've collected your sand fleas, keep them in a bucket of moist sand to maintain the moisture of their gills. Be careful not to submerge them in water, as they will drown. If the weather is hot, cover the sand with a damp cloth, and consider adding ice chips to keep everything cool. Remember to drain out the fleas' waste daily to prevent them from suffocating. Sand fleas will typically keep for 3 to 4 days in these conditions.
When you're ready to use your sand fleas as bait, start by putting some attractor beads on your line. Sand flea eggs are orange, and many fishermen believe this colour attracts fish. You can use small fluorescent orange bobbers to keep the bait just off the bottom. Next, attach a short monofilament leader. If you're using a light line, opt for a heavier monofilament leader of about 18 inches (45 cm). You can also attach a snap swivel to make it easier to change hooks or lures.
Finally, hook the sand flea lightly through the body. Thread the point up through the body above the telson (tail section) and belly sac toward the head, ensuring the crustacean can disperse its eggs. The ideal angle will cause the crustacean to be pulled to the side when you retrieve the bait. Some fishermen prefer to push the barb through the shell or remove it altogether.
With your sand flea bait ready, you can now target a variety of fish species, including surf perch, croaker, corbina, drum, whiting, pompano, striped bass, small sharks, and bass.
