North-easternmost record of Halosaurus ovenii Actinopterygii: Notacanthiformes: Halosauridae) in the Mediterranean Sea, with notes on its biology

A single adult female specimen of Halosaurus ovenii Johnson , 1864 was captured by trammel nets at a depth of about 200 m off the coast of Arbatax (Sardinia, Italy) in early April 2007. Macroscopic and microscopic analysis of the gonad showed a postspawning ovary. This is the fourth documented capture of this fish in the Mediterranean Sea, representing the north-easternmost record for this species in this geographic area. Furthermore, the present specimen was fished at the shallowest depth ever recorded before.
