    The length and weight of Thunnus albacares (Bonnaterre, 1788) off north Andhra Pradesh during 2012 - 2015 were studied and the length-weight relationship was found out. A total of 3,617 specimens were analysed and the reported length range was18 cm to 186 cm fork length. In the fishery, peak landings of size classes 41-50 cm and 111-120 cm were observed. Annual mean lengths ranged from 62.7 cm to 92.7 cm. The highest mean length of 92.7 cm was recorded in 2014 and the lowest mean length of 62.7 cm was recorded in 2015. Length-weight relationship was not found to differ significantly between sexes and the pooled relation was log W = log 0.016 + 2.996 log L. The growth pattern observed was isometric.
