Abstract
Jasus verreauxi (H. Milne Edwards)—known locally as the packhorse crayfish— is the less common of the two New Zealand species of spiny lobster (marine crayfish; J. edwardsii is the other), and is commercially important only in the north‐easlt of North Island. About 80% of the annual J. verreauxi catch is landed in 5 months of the year: November, December, January, February, and March. The fishery is small and unimportant compared with the total New Zealand fishery for both spiny lobster species. During the 5 years of this study (January 1962‐December 1966) the commercial catch of J. verreauxi amounted to only about 0.7% of the total spiny lobster catch during the same period. Limited daita collected by Marine Department suggest that the J. verreauxi fishery showed a downward trend during this period. J. verreauxi and J. edwardsii fisheries are briefly compared and biological differences between the two species are discussed.
