Why the Mud Crab?

Despite their not-so-appetizing name, these crabs are delicious to eat and like stone crabs, they have a lot of meat. They are pretty robust species as well and will eat a good variety of organisms in the water and are tolerant of a wide range of water conditions. Because of that and the fact that they grow very rapidly in captivity, there is a high demand to sell them. Mud crabs are in high demand in southeast Asian countries and in Australia. Usually, these critters are boiled and then seasoned or sautéed. Chili mud crab dishes are very popular. Sautéing them in onions and shallots with a bit of white wine is also a go-to dish.

Can you spot the crab?

The mud crabs in the mud flats can be found hiding in and under trees, buried into a patch of mud, or even just out in the open. The trick is to train your eyes to locate them despite the fact that their carapaces blend into the environment or utilize a stick or some sort of long, poking mechanism to prod the mud. If you encounter something hard in the mud with a kind of hollowness when you poke it, it may be a mud crab.

Once you’ve found them, catching them should be pretty simple. They aren’t very fast and can’t really hide anywhere other than where you’ve found them. If the location is accessible to you, chances are they can’t get far. You can use your hands to grab both nippers from the back. If you use this method, be sure to wear some type of protective gloves or just be very careful. Another way is to just place a bucket on the ground sideways and force them into the bucket. The possibilities to catch them here are endless. Be creative.

Finding mud crabs in mud flats so the simplest and most economical way to catch these critters. You don’t need bait or any tool for that matter. Just a steadfast determination and adventurous spirit. However, this may be the more difficult way to catch them.

If you can find places that look like the locations above, then there’s a good chance mud crabs live there.

To catch them, usually people will use traps called crab pots/dillies. Since the water will likely have poor visibility, you wouldn’t really want to actively try and catch them using, for instance, crab rings. Instead, opt for the method of setting and forgetting. The basics are you have some sort of sinkable trap that holds bait where crabs can enter but have a difficult time leaving. You toss the trap in the water and basically wait or go do some fishing. After a span of hours (some people will leave the traps overnight), you come back to check on the trap and hopefully you have trap full of mud crabs. You can learn all about rigging and setting crab pots here. As far as what bait is suitable for the best chances of catching mud crab, well, this is debatable. Mud crabs are ‘omnivorous’ scavengers. They are also cannibalistic. They will eat dead fish, barnacles, oysters, etc. Popular recommendations to use as bait include mullet and chicken parts. The smellier, the better.
