Abstract

In March 2005, an exceptionally large blue-eye trevalla, Hyperoglyphe antarctica (Carmichael, 1819), was captured by drop line off the south coast of Western Australia. The specimen measured 1066 mm total length, 968 mm fork length, was female and in spawning condition (hydrated oocytes were present). The sagitta was used to estimate an age of approximately 32 years. This specimen is one of the largest and oldest reported for this species and also contributes towards the knowledge of the reproductive biology of this species, which has not been investigated in Western Australia.
