his report documents the age determination protocol for longfinned (Anguilla dieffenbachii) and shortfinned (Anguilla australis) eels, describing the current scientific methods used in New Zealand for otolith preparation and age determination to ensure accuracy and consistency over time. A brief history and the changes in the methodologies used in ageing freshwater eels are reported, and a description of the reference collection, and annotated examples of freshwater eel otolith preparations are also included.

A characterisation and catch-per-unit-effort (CPUE) analysis were carried out for the South Island commercial freshwater eel fishery for fishing years 1990–91 to 2012–13 by eel statistical area, and for shortfin (Anguilla australis) and longfin (A. dieffenbachii) separately.

A characterisation and catch-per-unit-effort (CPUE) analysis were carried out for the North Island commercial freshwater eel fishery for fishing years 1990–91 to 2011–12 by eel statistical area, and for shortfin (Anguilla australis) and longfin (A. dieffenbachii) separately.

The commercial eel (longfin, Anguilla dieffenbachii; shortfin, A. australis) monitoring programme began in 2003–04 and aims to capture processor recorded data from all individual landings throughout New Zealand on catch weights, species composition, size grades, and catch location at the catchment level. This report provides results from the 2009–10 to 2011–12 fishing years and examines trends in the North and South Island time series.

Title: Survey of tuna in customary areas of ANG 14.
12_33_FAR.pdf
(2.8 MB)
3 catchments in ANG14 (Orari, Opihi and Waihao Rivers) were sampled by electric fishing and baited fyke nets. Shortfins were of the catch by both methods. Abundance of juvenile and larger shortfins declined with distance inland but there were no obvious habitat associations for longfins. Growth rates were below the average for shortfins from other South Island rivers but above average for longfins. There was evidence of depletion of large shortfins, but the lack of small longfins was a concern.
