Surface distribution of albacore tuna, <i>Thunnus alalunga</i> Bonnaterre, in relation to the Subtropical Convergence Zone east of New Zealand

Abstract

Trolling surveys showed that albacore tuna are about equally abundant in subtropical and Subtropical Convergence Zone surface waters off the south‐east coast of New Zealand. Few albacore were located in Subantarctic Surface Water, indicating that the Subtropical Convergence Zone is the southern limit for albacore in this area.
