Characterisation and length-based assessment model for scampi (Metanephrops challengeri) in the Bay of Plenty (SCI 1) and Hawke Bay– Wairarapa (SCI 2)

Abstract

Assessments of SCI 1 and SCI 2 stocks have been updated, and both were accepted. For SCI 1, SSB remains stable at around 75% SSB0. Fishing intensity has consistently been below F 40% B0. For SCI 2, SSB has continued to increase, and is between 89% and 113% SSB0. Fishing intensity peaked in 2002 but has declined in recent years, while SSB/SSB0 has increased. For both stocks, future catches up to 156 tonnes (SCI 1) or 200 tonnes (SCI 2) to 2021 are not predicted to reduce the SSB below 40% SSB0.
