Download FAR 2022/37 Catch-at-age sampling of Trachurus novaezelandiae from JMA 1 in 2019–20 and 2020–21

Commercial purse seine landings of Trachurus novaezelandiae from the Bay of Plenty purse seine fishery were sampled from length and age throughout the 2019–20 and 2020–21 fishing years. Catch curve total mortality estimates derived from the resulting age distributions suggest that levels of fishing mortality were sustainable in the areas fished. Age-length and length-weight parameter estimates are also provided by this report; these should be used instead of existing estimates for this species.
