I would like to discuss the differences between Finnish and Russian reservoirs on the example of Ladoga and Saimaa. And the differences are very big. Especially if we are talking about the southern part of Ladoga, where there are endless reed fields, extensive shoals and sometimes the complete absence of serious changes in depth.

Полная противоположность финская Сайма — огромное количество каменистых островов, крутые свалы и гряды камней. К примеру на Сайме свал возле границы камыша с двух до пяти метров — не редкость. На Ладоге я про такие места не слышал. Подобные отличия сильно влияют на тактику ловли и в целом подход к рыбалке.

Fishing for coastal reeds and rafting with a water parachute downwind are popular in Ladoga. On the Saimaa, it is more likely to catch stone ridges and promising braids near the islands and jig in the depths. Only trolling is equally popular. First of all, Saimaa is rich in large perch, it is really significantly more than in Ladoga. The same can be said about bream, but it is almost not caught in Finland.

Another difference, in the warm season, the coastal pike is not larger than three kilograms, with rare exceptions, but on Ladoga there are large specimens in shallow water more often.
