Title: Standardised CPUE indices for swordfish (Xiphias gladius) from the New Zealand tuna longline fishery, 1993 to 2012
FAR_2013_46_2677_SEA2012-16_Obj1, MS3, RR1.pdf (3.8 MB)
This report updates the CPUE analysis for the New Zealand surface longline fishery for swordfish, to be used in a revised stock assessment for the wider South Pacific region. Effective targeting of swordfish increased over time due to greater use of light-sticks, a concentration of fishing around the full moon and at night, and the legalisation of swordfish targeting in 2004.

Title: Port sampling of tuna longline catches for swordfish (Xiphias gladius) size composition in 2005–06.
FAR_2013_29_1317_TUN2005-02.pdf (461.8 kb)
 A shore-based catch sampling programme for swordfish was developed and implemented which was cost-effective, statistically sound and achieved high coverage of landings. Individual processed weights were collected electronically from licensed fish receivers, and a predictive relationship was used to convert these to catch-at-length. Length-specific sex ratios derived from scientific observer data was projected onto the estimates of catch-at-length to estimate sex-specific catch-at-length.
