Robja,
Wow! A great and very unusual report

! Maybe actually epic

!
They dipped whole bunches of little taters like that and even half or a third that size in tempura batter and fried 'em in clumps in oil 'till light, golden brown in Japan...delicious, too.
Don't think they "dock fish" them, or catch 'em one at a time, though. A man could starve to death doing it that way, ya know?
Never did hear how hard they fought or the right kind of gear for catching them, neither. Prolly a light tackle thing, though.
