Methods And Materials

The material described and illustrated in this guide was collected from fishing boats working off the north-west and south coast of Tasmania, between 1985 and 1987, and from CSIRO Southern Surveyor research cruises between Wilsons Promontory Victoria and Bermagui New South Wales , between April and December 1996, predominantly trawling in depths from 25 to 200 m. In addition, species were collected at the Melbourne markets from fishing operations in Bass Strait waters. Once fish were...

Definition Of Terms

Otolithen Sulcus Fisch

The predominant otolith features included in descriptions are shown in Figure 1 using a generalised otolith. Otolith descriptions for each species follow a standardised format. Some terms are in bold type to aid navigation. Each description begins with the size and shape of the otolith. Size using otolith diameter from posterior to anterior margin, otoliths were classed as very small lt 3 mm diameter . Scale bars used in all figures are 1 mm, unless otherwise noted. Shape terms used to describe...
