im asian xD and ive eaten bat ray before , although i rarely catches em and i do respect them for the "fight" they put up. i personally think they r somewhat edible if cooked correctly ( with no hint of the nasty slime they have) ..... and i actually went to that famous cook school in Napa valley, and the high end restaurant there, and i got served some fried stingray ( not sure if its bat ray) but .... man, that turned out really nice ... or perhaps its just because my parents made me eat it n it costed like 30 bux -_-
but next time i catch em, im gonna release them anyway, cuz trying them once is enough ^^;;
