Download FAR 2022/45 Growth of juvenile red rock lobster (Jasus edwardsii) in New Zealand and implications for stock assessment

An analysis of juvenile red rock lobster growth around New Zealand, based on existing length and mark-recapture based growth information, is reported here. The time lag from puerulus settlement to recruitment in stock assessment models is highly likely to be 2–3 years, when this occurs at 30–35 mm tail width (TW). Annual growth increment at 30 mm TW is about 9 mm based on Stewart Island growth information, about 12 mm at Gisborne, and potentially faster along the north coast North Island.
