Mizan | Mehdi Mohebbi Pour: The fishing season has begun in northern Iran as pelicans are catching fish along with fishermen. The Caspian Sea located to the north of Iran is the world’s largest lake. The fishing season there begins on October 12 and ends on April 4 the next year. Different species of fish live in the sea. The Caspian Sea accounts for a large portion of the world’s sturgeon. With the arrival of autumn, thousands of fishermen in north of Iran prepare their nets and head for the sea.
