How Do The Deadliest Catch Captains Target The Right Type Of Crab?

In that same thread, u/Aggressive-Set3049 compared crab fishing to other types of commercial fishing, pointing out that a great deal of research goes into the selection of fishing spots. They also noted that a crew's experience also plays an important role in the success of an expedition. "[It's the] Same as fishing for any specific fish in one big ocean," they wrote. "Depends on bait, time of year, where they live and what they eat. It's what makes a great fisherman a great fisherman. They know their migratory patterns, and they keep logs of past fishing trips to give them a general reference for future fishing."

For recreational crabbers, Crabbing Hub suggests that using a variety of baits can lead to success, including fish, chicken, turkey, eels, and even pig's feet. The site recommends augmenting any bait with oily fish like tuna or sardines, even suggesting that a can of tuna with a small hole in it can be an effective lure. 

Another recommendation is to use bait that is local to the waters being fished. "The best bait you could use is freshly caught fish from the same body of water where you are crabbing. Chicken, squid, turkey, or any type of oily meats will also get the job done."
