INTRODUCTION
This guide is designed to describe the sagittal otoliths of fish species that occur predominantly in the temperate waters of south-east Australia, but may extend from Western Australia through to New South Wales. The species included are mostly benthic, benthopelagic or mesopelagic in origin, or from inshore coastal habitats. From the sampling opportunities available to us, a total of 141 species, from 68 families and 15 orders, were collected and included, but this guide does not cover all fish species known from the area. As such, there is still a need for further collection and identification of otoliths, particularly for pelagic species.
Otoliths of Common Australian Temperate Fish: A Photographic Guide has been compiled primarily as a reference work for use in studies of the dietary composition of a range of marine animals, including fish, sharks, cephalopods, mammals, penguins and other seabirds. Ecosystem studies have been recognised as being increasingly important to the understanding of the marine system (EPBC Act, 1999). The study of the diet of marine animals, particularly the identification of teleost otoliths from the gut content of piscivorous predators, is integral to an understanding of their ecology and interactions with commercial fisheries (Croxall 1987, Gales and Pemberton 1994, McMahon et al. 1999, Tasker et al. 2000, Bulman et al. 2001, Childerhouse et al. 2001, Bradshaw et al. 2003). These dietary studies are presently limited by the lack of taxonomic accuracy in identifying prey items. Otolith structures, primarily sagittal otoliths, vary widely among fish species and are recognised as being species-specific (Maisey 1987). Being dense, otoliths are one of the last features to be digested and can therefore often be obtained from stomach contents and scats, and their distinctive morphology compared with reference otoliths to identify the individual prey species. As the range of diet studies increases, it has become apparent that guides to the otoliths of the fish of different regions are an essential element in the toolbox of ecologists. Otolith publications are available for specific regions around the world: the northeast Atlantic (Harkonnen 1986), the north-west Atlantic (Campana 2004), the south Pacific (Garcia-Godos Naveda 2001), the western Indian Ocean and south-eastern Atlantic (Smale et al. 1995), the Southern Ocean (Hecht 1987) and the Australian Antarctic territory, including Macquarie and Heard Islands (Williams and McEldowney 1990). These publications may include some species occurring in Australian waters, but, until now, limited information on otoliths has been available for Australian marine species.
Alternative research uses of otoliths Otoliths, which are present in all bony fishes, consist of a calcium carbonate (usually aragonite) crystal that grows continuously by accretion over the life of the fish. They are contained within a membranous labyrinth in paired otic capsules on either side of the skull. Three pairs of otoliths are present – sagittae, asteriscus and lapillus – with the sagittae being the largest in most bony fishes. Primarily an organ associated with balance, movement and hearing (Tavolga et al. 1981, Popper and Lu 2000), findings from otolith research have provided fisheries scientists with several valuable tools, particularly in the areas of fish ageing and population studies. Otoliths have become the primary structure for estimation of fish age, predominantly using otolith increment analysis techniques in adults, and applying alizarin marking techniques in larvae and juveniles. As these techniques have developed, the importance of accuracy and precision in age determination has become increasingly evident (e.g. Beamish and McFarlane 1983, Chambers and Miller 1995, Secor et al. 1995, Campana 2001). As such, validations of methods for estimating fish age continue to be assessed for many species (e.g. Milton et al. 1995, Fowler and Short 1998, Stewart et al. 1999, Dwyer et al. 2001, Dwyer et al. 2003).

Otoliths of Common Australian Temperate Fish
Otoliths have proved valuable beyond the studies of feeding, age and growth alone. Research into studies of populations – stock assessment and stock discrimination, together with fish migration and movement studies – all benefit from data derived from otoliths. Through the examination of otolith microstructure, patterns of chemically or thermally induced increments have been used to distinguish between populations or stocks of fish (Gunn et al. 1992, Proctor et al. 1995, Secor 1999, Campana and Thorrold 2001, Gao et al. 2001, Bastow et al. 2002, and others). As the chemical composition can be distinct for different water masses, trace elements incorporated into the surface of the otolith reflect the physical and chemical characteristics of the ambient water, and can be used to discriminate between groups of fish that have spent part of their lives in different environments (e.g. Thresher 1999, Campana et al. 2000). Strontium to calcium ratios have been used as indicators of
salinity, to show migration between freshwater, estuaries and saltwater environments (e.g. Edmonds et al. 1999, Bath et al. 2000, Pontual et al. 2003). Stable isotopes, particularly oxygen, have been used as indicators of the metabolic and temperature history of fish (e.g. Kalish 1991, Weidman and Millner 2000, Lenanton et al. 2003, Ayvazian et al. 2004). Other disciplines have also benefited from otolith research. Studies of archaeology and palaeoclimatology have based reconstructions of palaeoclimate on the elemental and isotopic composition of recovered otoliths (Anderson et al. 1997, Patterson 1998, Ivany et al. 2000, Wurster and Patterson 2001). Studies of ecology and ecomorphology have drawn on the implications of otolith structures and function, and tested these variations for some species and habitats (Gauldie 1988, Sideleva and Zubina 1990, Lombarte 1992, Arellano et al. 1995, Paxton 2000, Volpedo and Echeverria 2003) to provide a further source of information to fisheries studies.

METHODS AND MATERIALS
and were stored as TIFF files using Powerpoint software. Raw images were enhanced by sharpening contrast and making images lighter or darker to increase clarity. As the minimum SEM magnification was X10, the largest otoliths needed to be scanned in parts and ‘pasted’ together. SEM images of DSF and TMAG collected otoliths were carried out at the University of Tasmania, Central Science Laboratories, and stored as micrographic negatives. The species contained in this guide have been arranged by phylogenetic sequence of Order and Family, with species then listed alphabetically by genus. Scientific names are shown in bold italic typeface, with common names and previous nomenclature also provided after the recognised species name. This allows easy cross-referencing of predator–prey information from published literature where previous taxonomic naming has been used. Taxonomic names follow the nomenclature contained within the Codes for Australian Aquatic Biota (CAAB) website (http://www.marine.csiro.au/ caab/) (Rees et al. 2000) and, where included, other names cited in Gomon et al. (1994) and Last et al. (1983). For species not included in these latter references, previous taxonomic names follow the California Academy of Sciences, Catalog of Fishes On-line nomenclature, (http://www.calacademy.org/ research/ichthyology/catalog/fishcatsearch.html) which is regularly updated. Similarly, we have included the official common name for each species in bold typeface (obtained from CAAB), followed in brackets by other previously used common names. Fish length and weight data has been recorded at point of capture/collection. Otolith length data has been recorded at the time of otolith extraction, after cleaning. Where available, otolith weight and primordium position are from the Marine and Freshwater Resources Institute (MAFRI – currently Central Ageing Facility (CAF)) Final Reports 1 and 2, compiled for CSIRO from material collected during the listed Southern Surveyor research
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 identified, individual fish lengths and weights were recorded and otoliths removed and stored in seed envelopes or gelatin capsules. Otoliths were later soaked in distilled water and cleaned with a soft brush to remove any blood, tissue or otic fluids. Cleaned otoliths were weighed, measured and mounted onto numbered stubs, using double-sided carbon tape. Stub numbers were cross-referenced to the individual species details. Mounted otoliths were lightly sputter-coated as a requirement for scanning electron microscopy. Samples from CSIRO Marine and Atmospheric Research (CMAR) were sputter-coated with platinum, and samples from Tasmanian Museum and Art Gallery (TMAG) and Department of Sea Fisheries (DSF – currently Tasmanian Aquaculture and Fisheries Institute) were sputter-coated with gold. All mounted otoliths where then stored in lidded containers to minimise dust or damage. Scanning electron micrograph (SEM) images were taken of all otoliths. Descriptions were based on these images and original specimens. Where possible, a size range of otoliths from each specimen was photographed and described. Where there was extensive variation with ontogeny, this was also stated. All material described are sagittal otoliths, either left or right otoliths, and generally proximal side only, unless diagnostic features were found to occur on the distal surface. These instances are individually noted. SEM images from CSIRO collected otoliths were carried out at the CSIRO laboratories in Hobart

cruises. Brief details of distribution and ecology have also been provided, as a means of further aiding species identification. Line drawings of fish have been provided for each species. Used together with distributional and ecological information, these provide a quick reference to the fish morphology, and some assumption of the likelihood of predator–prey interactions. Line drawings have been predominantly taken from Fishes of Tasmania (Last et al. 1983), with permission from copyright holders, Department of Primary Industry and Water, Tasmania. The remainder are sourced from Gomon et al. (1994) or redrawn from Smith and Heemstra (1986). For each fish species, references are made to known data or published information on predators of that species. In many cases references identify the prey fish to only the Family or Genus level. In these instances, comment is made that the particular predator preys upon undistinguished species of that particular Family or Genus. If the respective group has more than one species represented in the atlas, we place the reference with the first species.
Because of the general lack of availability of this data to date, it was considered important to include all available length/weight data for the species included. As such, some data sets are very small. It should be emphasised that n and R values should be carefully noted when using these regressions. Further limitations do exist in this technique, for example, for juvenile fishes or after fish reach maximum size. Therefore, the size of fish should only be estimated over the size distribution of the sampled dataset. Where the data used contains both juvenile and adult specimens, this has also been noted and should be taken into account. Where available, morphometric data has been provided for each species within this guide. Data includes ratios for conversion of otolith weight to fish length, otolith length to fish length, and fish length to fish weight. With few exceptions, this data has not previously been reported. It will further assist in studies of dietary analysis and energetics.
Distribution, ecology and predator–prey information For each species contained in this guide, a brief distribution and ecology section has been provided. For dietary studies, using distribution and ecology data coupled with the distributional range of the predator from which the sample was taken, will enable the user to make some judgement on the likelihood of the predator–prey relationship. This may immediately eliminate some species from further consideration, provided the knowledge of the fauna of the area and the distribution of the particular species is considered to be reasonably well understood. Where available, predator–prey information has been included in this guide. But there remains much to learn – the marine food web and trophic structure of the temperate Australian region is complex. As such, the ability to identify trophic linkages through identification of prey remains is a significant tool in increasing our understanding of ecosystem functioning and the effects of perturbations on our marine environment.
Morphometric data sets Early morphometric studies identified a positive relationship between fish size and otolith size (Trout 1954, Templemann and Squires 1956), between fish weight and otolith length (Casteel 1974), and later between fish length and otolith length (Frost and Lowry 1981, Wyllie Echeverria 1987, Gamboa 1991). Generally, a simple linear regression can be used to describe these relationships. For species within this guide, information regarding fish length, fish weight, otolith weight and otolith length were compiled from original unpublished data, with standard error and sample values provided. The source of this data is noted and includes morphometric measurements from CMAR research cruises (1984–86 and 1995–2002) and TMAG measurements collected during predator– prey studies (1984–90).

DEFINITION OF TERMS
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.
Margin: shape and sculpturing of otolith edges. The general outline of the dorsal, ventral and posterior margins are given, followed by the sculpturing – that is ‘the finer surface features’ of that margin. Terms are illustrated in Figure 3, and follow the standard of Smale et al. (1995). Other terms used may include: • distal surface: the face of the otolith directed towards the exterior of the lateral surface of the fish, generally lacking distinct features; classified as seen in cross section as convex, concave or flat. • proximal surface: the face of the otolith directed towards the interior of the fish, showing prominent characteristic otolith features; classified as seen in cross section as convex, concave or flat.
Size: using otolith diameter from posterior to anterior margin, otoliths were classed as: • very small (<3 mm diameter). • small (3–5 mm). • medium (>5–8 mm). • large (>8 mm). Scale bars: used in all figures are 1 mm, unless otherwise noted.
Sulcus or sulcus groove: (also known as sulcus acusticus), a longitudinal depression on the proximal surface of the otolith. It may be divided into ostium (that portion of the sulcus anterior to the neck) and cauda (that portion of the sulcus posterior to the neck). For species within this guide, the sulcus is described according to the degree of differentiation as:
Shape: terms used to describe otolith shape are illustrated in Figure 2, and follow the standards and terminology of Smale et al. (1995). The following terms then appear in the same sequence as used in the otolith descriptions:
Figure 1

Otoliths of Common Australian Temperate Fish
Rostrum: where present, the portion of the otolith extending ventrally and anteriorly from the excisura notch.
• archaesulcoid: no differentiation into ostium and cauda and no features on floor of sulcus. • pseudo-archaesulcoid: no differentiation into ostium and cauda, but features are present on the floor of the sulcus. • heterosulcoid: ostium and cauda differentiated and unequal. • homosulcoid: ostium and cauda differentiated and equal.
Antirostrum: where present, the portion of the otolith extending dorsally and anteriorly from the excisura notch. Excisura: where present, the opening of the sulcus onto the otolith anterior margin; often with an associated notch.
The opening of the sulcus is generally onto one or more margins. Species within this guide fall into four categories, and are described as: • ostial: sulcus opens onto the anterior otolith margin only. • ostio-caudal: sulcus opens onto the anterior and posterior margins. • caudal: sulcus opens onto the posterior otolith margin only. • mesial: the sulcus is only open to the proximal (mesial) surface of the otolith and thus rostrum, antirostrum and excisura are absent.
Pseudo-rostrum: where present, the equivalent of a rostrum, but extending ventrally and posteriorly. This feature is only present in otoliths with a sulcul opening at the posterior margin of the otolith. Pseudo-antirostrum: where present, the equivalent of an antirostrum, but extending dorsally and posteriorly. This feature is only present in otoliths with a sulcul opening at the posterior margin of the otolith. Pseudo-excisura: where present, the equivalent of an excisura in an otolith with a sulcul opening at the posterior margin.
Colliculum: a raised part of the sulcus floor, occuring in the ostium (anterior colliculum) or in the cauda (posterior colliculum). (A secondary crest (pseudocolliculum ) may also occur, generally just above the crista inferior.) Where determined, the colliculum is described as: • homomorph: undifferentiated, or with two colliculi almost equal in size. • heteromorph: with two distinctly different colliculi. Collum: where present, a wall-like structure separating ostium and cauda.
Dorsal area and ventral area: the area on the proximal surface of the otolith lying dorsal/ventral to the sulcus. (May not be included in description if features are absent or non-descript.) May include: • dorsal or ventral depression: a depression in the dorsal/ventral area that is morphologically different from the rest of that area. • dorsal or ventral groove: narrow, elongate depression often running parallel to the otolith margin.
Crista: the rim of the sulcus dorsally (crista superior) and ventrally (crista inferior), ranging in development from absent or broken, through to a continuous, extended feature, which in turn may be poorly developed, or well developed, through to a raised, ridge-like margin to the sulcus.
Primordium: the nuclear region, which represents the innermost region of the otolith, formed during embryonic development; forms the commencement area for growth increments used for age estimates in fish. Description only provided where available from documented otolith sectioning.
