Abstract:

Port Jackson sharks are distributed throughout southern Australia, with evidence suggesting that potential subpopulations exist. If subpopulations are evident, then phenotypic variation among groups should result in differences in life-history parameters. The present study tested for patterns of spatial variability of life-history parameters among regional Port Jackson shark populations. Rates of growth from Port Jackson sharks caught in the gulf waters of South Australia were calculated on the basis of counts of vertebral increments. Growth parameters were obtained by fitting the length-at-age data to von Bertalanffy and Gompertz growth functions. While the derived growth curves fit the length-at-age data well (r2 ranged from 0.87 to 0.91), parameters showed considerable differences between the two functions, with the von Bertalanffy function providing the more realistic estimates of growth (combined sexes: k = 0.081 year–1, L∞ = 1232 mm total length and t0 = –1.937 years). Life-history parameters for South Australian Port Jackson sharks were collated with the available data for the species, facilitating comparisons among regional populations. Growth curves among populations varied significantly; however, considerable overlap in the length ranges of size at birth and sizes at maturity among populations were evident. Overall, the data presented here do not provide definitive support for the presence of subpopulations across the distribution of the Port Jackson shark, suggesting that molecular analysis maybe required to directly test for structuring.

Abstract:

Catches and by-catches were surveyed in the commercial prawn trawl fleets of Botany Bay and Port Jackson, two estuaries in the Sydney metropolitan area (NSW, Australia). Catches were surveyed in all tows during replicate fishing trips in each month during the 1990-91 and 1991-92 prawn trawl seasons in each estuary. Significant species-specific variabilities in abundances were detected between estuaries, between years, and between early and late in the fishing season. The mean annual ratio of by-catch to catch of prawns (by weight) was 2.5 : 1 for Botany Bay and 1.8 : 1 for Port Jackson. A mean annual by-catch (� 1 s.e.) of 142 � 14 t was taken from the Botany Bay fishery and 38 � 3 t from Port Jackson. These by-catches included large numbers of small recreationally and commercially important finfish: a mean annual by-catch of 1.52 �0.20 million fish from Botany Bay and 219� 23 thousand fish from Port Jackson. Despite uncertainties about the impacts of such by-catches on interacting commercial and recreational fisheries, it is recommended that strategies for the reduction of such by-catches be considered.

Abstract:

Contemporary diaries and the water-colours of artists such as the Port Jackson Painter vividly tell of Aboriginal life when the First Fleet in 1788 settled its cargo of convicts in Australia. Fishing was important around the waters of Port Jackson, whose Aboriginal inhabitants are recorded to have used the techniques of spear-fishing and angling. Were other methods also used? Fish remains from a shell midden provide an opportunity to investigate.

Full text

Abstract:

Tuscan-born and Spanish-trained Alessandro Malaspina (1754-1810) captained the most significant scientific expedition ever launched by Spain in the years 1789-1794. After a survey of the Spanish colonies in America, he directed the course of the Descubierta towards the South Pacific and anchored at Port Jackson on 11 March 1793. In my essay I will scrutinize the New South Wales leg of Malaspina’s voyage account, comparing 'Viaje político-científico alrededor del mundo' (the original 1885 Spanish edition) and 'Journal of a Voyage by Alejandro Malaspina' (its 2001 English translation), and integrating them with the captain’s secret reports. The examination of Malaspina’s comments on the infant colony will simultaneously expose the Spanish attitude to early British colonialism in New South Wales, and help assess Malaspina’s complex role as the first explorer who reached Terra Australis from the Italian peninsula.

Abstract:

SCUBA observations show that Port Jackson sharks repeatedly visit specific resting sites on ocean reefs at South Bondi (New South Wales) and, when disturbed, move directly from one site to another. The sharks also use specific resting sites in Sydney Harbour and, when transferred by boat to different localities within the harbour, up to 3 km away, return to their original resting sites. The sharks migrate from as far south as Tasmania to Sydney Harbour to lay their eggs in specific sites. Speculative extrapolation from the above observations suggests that Port Jackson sharks must have a highly developed spatial memory.

Abstract:

Knowledge of the broad-scale movement patterns of sharks is essential to developing effective management strategies. Currently there is a large bias in studies focusing on species that are either large apex predators or found in tropical to subtropical regions. There is limited knowledge of the movements and migrations of benthic and temperate shark species. The present study used passive acoustic telemetry to investigate the movement patterns of a benthic shark species, the Port Jackson shark (Heterodontus portusjacksoni). Individuals were tagged with acoustic transmitters between 2012 and 2014 and their movements were monitored within Jervis Bay and along the east Australian coastline for up to 4 years. Male and female Port Jackson sharks demonstrated high levels of philopatry to both Jervis Bay and their tagging location across multiple years. Although males and females did not differ in their arrival times, females departed from Jervis Bay later than males. Approximately half the tagged individuals migrated in a southward direction, with individuals being detected at Narooma, Bass Strait and Cape Barron Island. This study provides conclusive evidence of bisexual philopatry in a benthic temperate shark species, confirming previous hypotheses, and presents the most detailed migration route for Port Jackson sharks to date.

Abstract:

Abstract This article is a contribution to the debate over Australia’s convict beginnings and the nature of the British colonization of New South Wales. The early agriculture of the convict colony is set in the maritime context of imperial rivalries and visions of empire in the Pacific Ocean. When the Port Jackson settlement is viewed from this maritime perspective, it is apparent that agriculture was an imperial imperative of the Pitt administration. The design and early function of the settlement as a port of shelter and refreshment ensured that, despite initial despondency and drought, a bountiful and secure agricultural hinterland was in the making. Within five years after the planting of New South Wales, convict settlers, mixed agriculture, and imperial designs had transformed "a rude, wild country into a pleasant garden." As a planned, self-sufficient, maritime settlement, Port Jackson rapidly developed its capacity to produce a surplus of antiscorbutic seamen’s greens essential for a distant port and naval base to become an assured resource of refereshment, services, and supplies necessary for Britain to "effectively occupy" the oceanic territory of New South Wales and thereby integrate the development of a global empire.

Full text

Abstract:

This study surveyed levels of trace elements and hydrocarbon contamination in Australian seaport environments. Different activities contribute to discharges of trace elements and hydrocarbons into estuarine and marine environments. The elements of highest concern are As, Cu, Pb, Zn and Ni at Port Derwent, with Cd, Zn, Cu and Pb at Port Kembla and Zn and Cu at Botany Bay all exceeding the Australia and New Zealand Environment Conservation Council standards. Concentrations of some elements (Zn, Pb and Cu) in sediments at Port Kembla, Port Newcastle and the Derwent estuary are also higher than the Inter Sediment Quality Guidelines. The concentrations of polychlorinated biphenyls, dichlorodiphenyltrichloroethane and chlordane in the aquatic biota at two eastern ports (Port Jackson, Port Brisbane) are also among the highest in Australia and similar areas around the world. These findings provide baseline information on which to prioritise further research and formulate strategies to improve water quality in Australian port environments.

Abstract:

Metaprotella haswelliana (Mayer, 1882), the type species of Metaprotella, was originally described from Port Jackson, New South Wales, Australia and was reported from there in literature published between 1882 and 2003. However, the type specimens are lost and no further specimens could be found in recent surveys in New South Wales waters. The only current records are from Albany, Western Australia and from Port Phillip Bay, Victoria. Based on the materials from Western Australia, the poorly known type species, Metaprotella haswelliana is redescribed, a neotype is assigned, and the genus Metaprotella Mayer, 1890 is redefined.

Full text

Abstract:

Stormwater runoff has resulted in heavy metal contamination throughout much of the Port Jackson estuary, Sydney, Australia. Metal partitioning was investigated in the benthic estuarine sediments of Iron Cove, an off-channel embayment of Port Jackson. Contamination was greatest near the stormwater canal, where sediments were anoxic and contained high concentrations of sulfide in the porewater. Away from the canal a layer of non-cohesive, sub-oxic surficial sediment containing high dissolved iron was found overlaying a more cohesive substratum. At all sites, porewater Cd, Cu, Ni, Pb and Zn were <2.5 g L–1, and negligible metal release was observed upon sediment resuspension. According to water quality guidelines, the ecological risk posed by dissolved metals from the Iron Cove sediments is low. Estimated fluxes of Cd, Cu, Ni, Pb and Zn from the sediments were calculated to be <0.2 mol m–2 day–1. The rapid oxidation then hydrolysis of iron(II) in porewaters caused a drop in pH and the formation of iron hydroxide precipitate. These processes may affect dissolved metal concentrations; hence, oxidation of samples must be avoided during sampling and extraction procedures. Sediment-bound zinc was the metal most easily mobilized.

Abstract:

Commercial fisheries can discard a considerable volume of sharks and rays, which, as a group, are of high conservation concern. In Western Australia (WA), commercial shark fishing commenced in the 1940s; however, catch time series are not available for discarded species. The present study quantified catch (i.e. dead individuals) time series of discarded sharks and rays in WA’s shark fisheries using on-board observer information collected since 1993 and testing assumptions through sensitivity analysis. Overall, 18 shark and ray taxonomic groups were discarded, comprising ~20% of the observed catch by number. Port Jackson shark, southern eagle ray and spurdogs were the most commonly discarded elasmobranchs, followed by western wobbegong, angel sharks, stingrays, and guitarfish and shovelnose rays. For the base case scenario, the catch of these species was small, peaking at 12.6, 5.6, 1.3, 1.8, 4, 1.3 and 2.7 tonnes (Mg) respectively, given their low post-release mortality (PRM). Current catch levels were even lower (e.g. <5 Mg for Port Jackson shark). Other discarded elasmobranchs were rarely caught. Assuming 100% PRM resulted in higher annual catches, highlighting the need for further research on the PRM of sharks and rays. The reconstructed catch series will be used in risk assessments to determine the sustainability of discarded species.

Abstract:

This study investigated the behaviour of two Elasmobranch species; Southern fiddler ray (Trygonorrhina dumerilii, n = 1) and Port Jackson shark (Heterodontus portusjacksoni, n = 4) and two teleost species; moonlighter (Tilodon sexfasciatus, n = 1) and banded morwong (Cheilodactylus spectabilis, n = 1) living within a single enclosure. For this study, two treatments were compared, the original enclosure design, and then after the enclosure had been renovated to more closely represent the species natural habitats, with a raised front viewing glass to prevent visitor interaction. Behaviours such as resting, swimming and abnormal behaviours such as surface and perimeter swimming (elasmobranchs only) were recorded as well as location within the enclosure, for 10 days pre and 10 days post renovation. The Port Jackson sharks significantly reduced the performance of abnormal behaviours after renovation, and significantly increased the time spent near the exhibit front. The Southern fiddler ray increased resting post renovation, while the teleost species also spent more time near the exhibit front. Although a small sample size was used, the results suggest that a more naturalistic environment with multiple micro-habitats and effective visitor barriers allows for a greater proportion of the day spent exhibiting natural behaviours, greater space use and reduced stereotypes.

Full text

Abstract:

Restricted gene flow and reproductive philopatry are increasingly being described in marine predators such as sharks. However, observing shark reproductive behaviour in situ is problematic because of issues associated with sampling in the marine environment. As such, molecular tools have become fundamental to unravelling complex mating behaviours. In this study, we examined patterns of genetic structure in the oviparous Port Jackson shark (Heterodontus portusjacksoni) using 10 microsatellite loci and the mitochondrial (mt)DNA control region. Patterns of genetic structure were investigated between breeding aggregations in Sydney and Jervis Bay, as well as between two sites within Jervis Bay. Significant genetic differentiation was detected between Sydney and Jervis Bay using mtDNA, but no structure was observed within Jervis Bay. No significant genetic differentiation was found with microsatellites within or between aggregations. Mean assignment index values were significantly higher for females than males in Jervis Bay, but not in Sydney. Both females and males migrate inshore during the Austral winter for breeding, but it appears females may exhibit higher levels of reproductive philopatry than males. This is the first study to document reproductive philopatry in an oviparous shark, highlighting the importance of conserving and appropriately managing breeding sites for H. portusjacksoni and potentially other oviparous shark species.

Abstract:

In this study, the potential of two adsorbents prepared from Port Jackson (PJ) plant for the removal of Janus Green (JG) and Victoria Blue (VB) dyes from wastewater was investigated. One of the adsorbents was prepared from Port Jackson by employing the plant’s leaves in their natural form after washing while the second one was obtained by treating the leaves with concentrated sulphuric acid. The adsorbents were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Batch adsorption experiments were conducted with different initial concentrations of dyes, adsorbents doses, temperatures and contact times to determine their effects on the process efficiency. Equilibrium isotherm, kinetics and thermodynamics of the processes were also evaluated. The percentage removal of the dyes by the two adsorbents increased with increasing contact time and adsorbent dosage but decreased with increasing temperature. The kinetics parameters obtained were found to follow pseudo-second order model, suggesting that the rate limiting step may be chemisorption. Thermodynamic studies reveal that the adsorption processes were spontaneous and exothermic in nature as evident from the negative values of Gibbs free energy (G0) and enthalpy (H0) obtained. The processes were accompanied with decreased randomness as shown in the negative change in entropy (S0). It can be concluded that the two adsorbents have good potentials for remediating JG and VB dye-contaminated wastewater.

Abstract:

Movement ecology has traditionally focused on the movements of animals over large time scales, but, with advancements in sensor technology, the focus can become increasingly fine scale. Accelerometers are commonly applied to quantify animal behaviours and can elucidate fine-scale (<2 s) behaviours. Machine learning methods are commonly applied to animal accelerometry data; however, they require the trial of multiple methods to find an ideal solution. We used tri-axial accelerometers (10 Hz) to quantify four behaviours in Port Jackson sharks (Heterodontus portusjacksoni): two fine-scale behaviours (<2 s)—(1) vertical swimming and (2) chewing as proxy for foraging, and two broad-scale behaviours (>2 s–mins)—(3) resting and (4) swimming. We used validated data to calculate 66 summary statistics from tri-axial accelerometry and assessed the most important features that allowed for differentiation between the behaviours. One and two second epoch testing sets were created consisting of 10 and 20 samples from each behaviour event, respectively. We developed eight machine learning models to assess their overall accuracy and behaviour-specific accuracy (one classification tree, five ensemble learners and two neural networks). The support vector machine model classified the four behaviours better when using the longer 2 s time epoch (F-measure 89%; macro-averaged F-measure: 90%). Here, we show that this support vector machine (SVM) model can reliably classify both fine- and broad-scale behaviours in Port Jackson sharks.

Abstract:

The genital ducts of Heterodontus portusjacksoni are lined by a ciliated epithelium. In the ductuli efferentes the epithelium is low and contains numerous intraepithelial leucocytes which often contain large dense bodies. All epithelial cells are ciliated and are characterised by apical vesicles, vacuoles and glycogen granules, some rough endoplasmic reticulum, dense bodies and lipid droplets, and a Golgi apparatus. The initial segment of the ductus epididymidis is lined by a very tall epithelium of ciliated and non-ciliated cells. The non-ciliated cells contain numerous apical vesicles, a large Golgi apparatus and numerous mitochondria and secretory granules in close association with an extensive endoplasmic reticulum. The terminal segment of the ductus epididymidis is lined by a low columnar epithelium. A proximal region, occupying part of the head of the epididymis, is similar to the epithelium in the ductuli efferentes. Distally, all the epithelial cells are ciliated. They are characterised by considerable dilated endoplasmic reticulum, a Golgi apparatus, apical vesicles, and numerous mitochondria and secretory granules. The secretory tubules of Leydig's glands are lined by a very tall epithelium with non-ciliated cells containing extensive, dilated, rough endoplasmic reticulum, a large Golgi apparatus, and numerous mitochondria and secretory granules. The significance of the structural differentiation of the duct is discussed in relation to the evolution of the mammalian epididymis.

Abstract:

The family Colomastigidae is represented on the Great Barrier Reef by a total of six species, all members of the genus Colomastix, three of which are new to science. Ranges of the three known species, C. japonica Bulycheva, 1955, C. lunalilo J.L. Barnard, 1970 and C. plumosa Ledoyer, 1979, are extended to include the Great Barrier Reef. Of the three new species, two are found only on the Reef and the third also occurs near Port Jackson, New South Wales. All six species are fully described and illustrated.

Abstract:

one of 353 port jackson sharks, heterodontus portusjacksoni, caught off the southern coast of western australia, was a hermaphrodite. the female reproductive tract consisted of a large (functional) right ovary with three large yolked ova, a small non-functional left ovary and two well-developed uteri and oviducal glands. the male tract comprised two conspicuous but undeveloped testes, two vas deferens and two calcified claspers with grooves. this individual represents the first published example of hermaphroditism in the order heterodontiformes and is a rare example of an elasmobranch with a complete suite of both male and female reproductive structures.
