Lobster evolution

July 7th, 2008 (07:05 pm)

Maine has laws controlling the lobster fishing industry, to preserve the population. For example, you can't bring in a lobster that's carrying eggs, or one that's over 2.5 pounds (since bigger lobsters lay more eggs).

Massachusetts has no such laws.

Therefore, there exists a selective pressure for lobsters to evolve that will avoid Massachusetts waters.

Likewise, I imagine, with birds whose migratory patterns take them into areas where hunting is permitted part-year.

I'm not sure that's the way that works.

There is an environmental change that favors lobsters that don't respond to traps in the Massachusetts waters; it's a range thing, not a pressure...more like a geographical predator difference.

Like I really have a clue. I don't. Fearless_em is the one to ask.
