Matsya Avatar or fish incarnation of Lord Vishnu is his first of Dashavatar (10 divine incarnations). The main purpose of Vishnus Matsya avataram was to warn the world about the Maha Pralay (deluge).
In Hindu religious history, the fish manifestation of Lord Narayana, the Matsya Avatar, does not have importance in terms of worship, rituals, customs and traditions. In ISKCON temples and some other Viashnava temples, Matsya Jayanti is celebrated with performing special puajs and archanas, and reciting Matsya Purana.
There is only one temple in India dedicated to Lord Matsya – Nagalapuram Veda Narayana Swamy Temple near Tirupati in Andhra Pradesh. The presiding deity of the temple is Lord Matsya and the idol has the head and torso of Lord Vishnu and golden human-like feet. Matsya Jayanti is observed with utmost gaiety in Nagalapuram Veda Narayana Swamy.
