Meat with mushy texture originates from soft-shelled crabs, a problem which can easily be rectified by culling. Black discolouration on the other hand, is likely caused by the enzymatic oxidation of polyhydroxy- phenyl and aminophenyl compounds in the tissues.

The only way you can accurately estimate your crab's age is if it dies. Then the otoliths, small concretions of mineral deposits, which sit atop the crab's balance organ (located at the base of each antennule), need to be removed. The otoliths can be sectioned and the number of growth rings counted.

Crab can be frozen for up to three months before beginning to lose its flavor, though Dungeness crab should not be frozen for more than one month and Alaskan king crab legs should not be frozen for more than six months.
