Environmental Proxy

Freshwater mussels in Australia are rarely studied for their life history and potential as palaeoclimate proxy archives. Therefore, we studied three freshwater mussel species from the Williams River, Hunter Valley, Australia, namely Alathyria profuga, Cucumerunio novaehollandiae and Hyridella drapeta, to identify their potential as new environmental proxy archives from Australian freshwater bodies. Growth analysis revealed that A. profuga and C. novaehollandiae produce distinctive growth lines, which allow the first identification of age and growth structure of these species. The oxygen isotope ratio in A. profuga shells and high-resolution element concentrations in all three species show cyclic, annual variations. A high correlation between growth rates and the combined winter air temperature and annual rainfall, as well as accurate temperature reconstruction using oxygen isotope values in the shells suggest that A. profuga has good potential as an environmental proxy archive. However, the low correlation observed between the Sr:Ca ratio and temperature limited the usefulness of the Sr:Ca ratio in A. profuga shells as a water temperate proxy. In contrast, growth rates and element ratios of C. novaehollandiae do not indicate a significant relationship with environmental variables, suggesting that this species, together with H. drapeta, is probably not suitable for palaeoclimatic studies.

The Australian freshwater mussel Hyridella depressa sequesters elements in calcium phosphate (CaP) granules that form extensive aggregations in its tissues. Elements contained in these granules were determined by X-ray microanalysis of river and lake mussels from the Hawkesbury–Nepean River system, New South Wales. Granules in freeze-substituted mantle tissue were analysed to determine the variation in element profiles in granules among mussels and among sites. For the common elements Ca, P, Fe, Mg and Mn, granule composition reflected catchment lithology and site trophic status and indicated exogenous input. These were most important for differentiation among lake sites and also indicated differences between lake and river mussels. Site differences seen with some common elements in granules from lake mussels correlated with differences in water chemistry. Trace elements, particularly Al, Cu, Zn and Pb, were also important in lake and river site differentiation. The granules play a major role in element dynamics in freshwater mussel tissues and provide a focal structure for direct analysis of element accumulation by these bivalves. The results indicate that characterization of element content of granules in mussel populations would provide valuable insights into animal–element interactions in freshwater systems for ecological and ecotoxicological investigations.

Iron Concentrations

The accumulation of iron, manganese, zinc and cadmium by freshwater mussels in the River Murray, South Australia, and their response to changes in environmental iron concentrations are considered. Metal loads varied markedly between individuals from the same population. The variability is accounted for partly by systematic relationships between metal loads and body weight and age, but not sex. The distribution of metals between the major organs is discussed, but the analysis of separate organs showed no advantage for biological monitoring. Comparisons between iron concentrations in river water and in mussels showed no clear correspondence. The study suggests that V. ambiguus may not be a good short-term monitor of iron, but still may have potential as a long-term and site-comparison monitor of metals. once inherent variability is taken into account.

Annulus Formation

The age and growth of Lutjanus adetii and L. quinquelineatus from the central Great Barrier Reef were determined from studies of annuli in sectioned otoliths (sagittae). The period of annulus formation was validated by oxytetracycline labelling of externally tagged fishes. For L. adetii, validation was obtained from tagged fishes that were recaptured after a minimum of 12 months at liberty, the first time this has been achieved for a Lutjanus species. A single opaque and translucent zone was formed once a year, with the opaque band (annulus) being formed during the winter months. Otolith weight was strongly correlated with age for both species. There was significant differential growth between the sexes in length-at-age and weight-at-age for both species, with males growing larger than females. The oldest individuals found were a male L. adetii of 24 years of age and a female L. quinquelineatus of 31 years of age. The shape of the growth curves were steep for the first few years and then became asymptotic. The annual instantaneous rate of natural mortality (M) was 0.235 for L. adetii and 0.154 for L. quinquelineatus, representing an annual survivorship of 79% and 86%, respectively. The protracted longevity and low natural mortality rates imply that both L. adetii and L. quinquelineatus are vulnerable to overfishing despite their small size.

The early life history of the freshwater mussel H. (H.) drapeta was investigated between September 1975 and November 1976. Observations from this study are basically consistent with those from previous investigations of glochidia of Australian freshwater mussels. The glochidia were found to be subtriangular in outline and possess an S-shaped larval tooth on the ventral margin of each valve. The dimensions (average�standard deviation) of the glochidia were: height 0.23� 0.01 mm; length 0.33�0.01 mm; height/length ratio 70.6�2.7%. The glochidia were observed to parasitize the river blackfish, Gadopsis marmorutus and the galaxiids Galaxias maculatus and G. olidus. Peak infections occurred between July and February. A single brown trout, Salmo trutta, was observed to be infected during one peak infection period. The gills of host fish were the major site of attachment and the glochidia were observed to be surrounded with a layer of epithelial tissue.

Detailed Work

This study is the first detailed work on the age and growth of the leaping mullet (Liza saliens, Risso 1810) in the central Mediterranean. During the period 1991-1995 the age and growth of leaping mullet from the Messolonghi -Etoliko lagoon system (western Greek coast) were studied. Age and growth determinations were based upon otolith samples taken from 537 fish. Marginal increment analysis was used to validate age determination. Annulus formation took place around November each year. The back-calculated lengths at age estimated from the otoliths showed no differences between sub-areas of the lagoon system and the recorded limited between-years variability showed no persistent temporal pattern. The maximum age of leaping mullet in the Messolonghi - Etoliko lagoon was 5 years for males and 6 years for females. The von Bertalanffy equation (L‡=32.99±1.25 cm, k=0.258 ±0.017 year-1, t0=-0.47±0.04 year) accurately describes the growth of the total length of leaping grey mullet for all life stages (fry, juveniles and adults). A large spread and length overlap characterized the age groups. The estimated Length-Weight relationships were common for the two sexes (W=0.0079L3.01).
