Thanks @petertheo, slowly getting better. Bass are not really an edible fish from what I'm told, also the lake is likely quite polluted. So I currently don't eat any of my catches. However if it was a different kind of fish (and location) I might keep one.

I keep seeing people here in Korea catching dozens of carp and taking them all home. They each fish with between 6 and 15 rods per person. The fish simply don't stand a chance and there's certainly no challenge. They are not fishing as a food source, but for sport (you can tell by their branded fishing clothing, expensive equipment and huge 4x4 vehicules - it's all about being flashy over here)
