Browsing the portal the other day I did a double-take when I saw that this same statue called The Struggle (Borba) by Simeon Roksandric (1874-1943) is in Zagreb. Roksandric had made one statue for the great Balkan exhibition in London in 1907. During the transport to or from London, Roskandic got word that the ship carrying the sculpture had sunk. So he made another statue from the same cast.
It turned out that this was untrue and he ended up with two identical statues. The Belgrade City Council decided to buy one in 1912, and Zagreb bought the other.
Like my fellow blogger in Zagreb, I was unable to find any information as to exactly what this statue represents, other than the obvious fisherman strangling a snake. Tried Googling in several languages, nothing!
