Download FAR 2014/59 Age composition of orange roughy from ORH 3B (Chatham Rise: northwest ,1994, and northeast,2013), and from ORH 7A (Challenger Plateau in 1987, 2006 and 2009)

Age compositions of orange roughy were estimated from three spawning plumes (Main Plume, Rekohu Plume, and Mount Muck) on the northeast Chatham Rise (ORH 3B) sampled in 2013, from a 1994 wide area research survey on the northwest Chatham Rise (ORH 3B), and from three research surveys on the Challenger Plateau (ORH 7A) in 1987, 2006 and 2009. The distributions were produced for use in assessments of these stocks.
