It would probably depend on whom you ask. But back in the late 90's there were some conditions put on crabbing.
I don't know if this happens every where, but in Houston Texas, if you are crabbing, you are not allowed to take the females. If you catch any, you must throw them back in. And yes, it is real easy to tell the females from the males.
Turn the crab over and on there belly there is a "V" shaped flap, the female's is wider than the males.

Do blue crabs swim?
Blue crabs, like lady crabs, are definitely swimming crabs. The largest population of the blue crab can be found in the Chesapeake Bay.
What would happen to Chesapeake Bay if the amount of blue crab were to increase in the ecosystem?
Well first of all, the prey of the blue crab would decrease in population and the predators would increase in population. As a result the whole food chain would be thrown off. organisms which have the same diet, live in the same territory as the blue crab would also be affected because an increase in the blue crab population would mean a decrease in the natural resources that those blue crab exploit. if the blue crabs were able to keep a steady or exponential population growth, barring the natural resources around them lend way for population growth the blue crabs would eventually hit their carrying capicty. One they reach and begin going beyond this capacity the Blue Crabs would have to outcompete their selves for dwindling natural resources, mates, food, etc. Eventually the population would decrease because of this interspecies competeion as a result overexplotiation of natural resources. Things could in the entire ecosystem could return close to normal considering the no other species went extinct as a result of Blue crab population growth or no enviromental changes occured a sa result of this growth.
