how does zaroff stock his island with game

General Zaroff stocks his island with game, meaning human prey, by deliberately causing shipwrecks near his island. He manipulates the channel lights to mislead ships into dangerous rocky waters, causing them to wreck on the sharp reefs surrounding the island. The survivors of these shipwrecks become Zaroff's human game for hunting on the island, which he considers the "most dangerous game" due to human reasoning ability. This method ensures a steady supply of victims for Zaroff's cruel and deadly hunting game.
