Residents and police said the strike was being observed in other towns in the Muslim-majority Kashmir valley.
In August, tens of thousands of Muslims took to Srinagar's street to demand that the UN recognise the Himalayan region's right to self-determination.
In the past few months, Indian-administered Kashmir has witnessed the biggest pro-independence demonstrations since clashes erupted in 1989.
The protests have been met by a tough crackdown by Indian security forces.
The UN has maintained a presence in the disputed area since 1949 and currently monitors the Line of Control dividing Indian- and Pakistan-controlled Kashmir.
