Here is just an example, 21 Taimen in 2h 40min. Factor in the lure damage, and gear wear 794 silver. This should really be a valuable fish, belaya isn't a place a low level is going to be trying to fish this. So really its a fish in a level 30 waterbody, powerful, and does take some time to be fishing them. Compare this to sturgeons or even the UL fishing here at Tung which pays way more silver in the same time on much easier fish (way less gear dmg etc) = much more profit overall.
Currently I am fishing them for the enjoyment of the fight lol, but sure would like to be rewarded a bit better for the effort to ^^
