Twelve-year-old Premlal and his friends spend hours every day in the paddy fields of their village Bhinjain in Chakai block of south Bihar. It is monsoon and the children use an age-old technique of blocking water in paddy fields by putting up barriers. The water is then drained out, leaving behind large puddles. Since fishes reach fields with rain water during monsoon, children can easily catch them. Premlal is a Santhal, member of the scheduled tribe largely concentrated in Jharkhand, Bihar, Tripura, Odisha and West Bengal.
