Don't know about "shallow", but some 45yrs. ago, my BIL used to fish
carp in Chautauqua Lake here in western NY using a bow rig with 100lb.
test line. This was when they were spawning and would come up to roll
in the weed beds. I helped row the boat and pull them up. When he hit
them, they'd head straight for the bottom and try to tangle in the
weeds, so it was a matter of literally hoisting them up. Don't know
the weights, but I know we hauled out a lot of 5' ones, and more than
one that exceeded 6' long. His Dad would skin them, cut out the mud-
streak, soak them in salt brine overnight, then smoke them in an old
refrigerator, then sell them to guys in the bars for $1/lb, guys who
normally wouldn't touch Carp on a bet, considering it "ni**er" food.
Spawning in the weed beds sounds about right.
As far as shallow is concerned, unless the fish is in relatively
shallow water and breaks the surface now and then, you're not going to
have much of a chance with a bow and arrow.
Where I grew up those weed beds were shallow, maybe 2'-3' at most.
My dad learned at an early age how to dress out carp.
Cut 1/2" on either side of the dorsal fin to get rid of the mud vein
and 1/2" above the belly fins, again to get rid of the "gamy" taste.
You basically end up with two fillets.
He never learned how to smoke them and preferred fish no bigger than 5
Can still remember he would bake them in the oven with a strip of
bacon on each fillet, pinned in place with tooth picks.
