sandsharks/dogfish

[Jimbo]

I mentioned in another post I was at the Chatham fish pier this week. Over the past several years I've stopped by a number of times and when the commercial guys unload, the fist bins are full of what looks like sand sharks or I guess maybe non-spiny dogfish. So I have a few questions about that. I had read in other posts that to eat them you need to bleed or skin them soon after catching or they go bad because [rumor has it] they pee through their skin. So if they're unhooked and thrown in a bin as is and it takes a while to get back to the dock aren't they going bad the whole ride in? Next question, they all seem to be about the same size give or take a couple inches. Hardly any really bigger or smaller, boat after boat after boat. Is there just one size they take back? Or why is it such a uniform catch? And if anyone knows, what happens to them from Chatham? Do they end up in the fried fish platter at the local restaurant or are they exported somewhere?
