yes basically the same techniques apply, with variants related to bottom and visibility: if it has been raining with streams pouring in, or if it's very hot in summers and micro-algae grow, you could find yourself doing aspetto with a 60cm gun!!!
However it's agguato for pike, tench and perch, aspetto for black bass and Cephalus Cabeda (a sort of freshwater mullet), rock and hole for eels and turbots. There are also carps, gizzard, bluegill and lake trouts (but trouts have become rare).
The lake we're talking about, Garda, is very deep (340 meters in the deepest pit) with 25 different local winds and lots of different types of bottoms.
The behaviour and distribtion of fish may change a lot according to the season, and thus the techniques. In the winter all fish except gizzards, bluegills and mullet stay 30 meters deep. Pikes come shallow in early spring, then the sink back to 30 meters in summer, and get shallow again in sept/oct, and finally go back to 30 meters for the winter.
Deep agguato for pike is the most difficult technique: you must dive slow motion "dead-leaf" style down to 30 meters in dark, murky, 7°C cold water. It's not for everyone! (that's why I think I'll wait till april).
I tried a hunting session in the lake three weeks ago. Could stay in just for half an hour (too cold) but I did hit something for dinner. I'll post some pics soon.
