60, according to US and Canada standards. How many dozens are in a bushel of crabs? Depending on the size of the crab, as many as 7 to 8 dozen crab will fill a bushel.   Jumbo crabs (6 to 6-1/2  in dimensions) will yield 5 to 6 dozen per bushel.
Really tiny crabs may take only days or weeks to molt (One of mine molted within two days). They will mostly likely molt about four to ten times a year. Any larger than a baseball, it could take longer than four-seven months. However this will occur about once to twice every two years. All of this is approximate, use it to determine around how long your crab(s) will take to molt, as well as how often. Also, if you have more then one crab(which is reccommended) remember to isolate them from the other hermit crabs during this time period.
