Summary statistics for 90,817 striped mullet, Mugil cephalus, tagged and released in the 1991 pilot experiment to evaluate 
release-season effects on hatchery releases in Kaneohe Bay. Unique batch codes were used to identify fish from each cell in the 
matrix. Spring release lot 1 occurred on 3 May, lot 2 on 10 May, and lot 3 on 17 May. Summer release lot 1 occurred on 12 July, lot 
2 on 19 July, and lot 3 on 26 July.
