I went on the 3rd round to Mednoye, in 5 hours I got almost 2 premium cages, I had to run to sell the cheapest one.
The total farm for the tour is about 3500 and a nice bonus in the form of 6 trophies (4 crucian carp + gray crucian carp + angry crucian carp)
67:59 clip 8 (hand fed 20 balls real every half hour)
everything else is on the screenshots
