Thesis submission for the degree of Doctor of Philosophy Thesis Title and Abstract Declarations Inclusion of Publications Statement Corrected Thesis and Responses Thesis Title Dynamic distributions of coastal zooplanktivorous fishes Thesis Abstract Zooplanktivorous fishes are an essential trophic link transferring planktonic production to coastal ecosystems. Reef-associated or pelagic, their fast growth and high abundance are also crucial to supporting fisheries. I examined environmental drivers of their distribution across three levels of scale. Analysis of a decade of citizen science data off eastern Australia revealed that the proportion of community biomass for zooplanktivorous fishes peaked around the transition from sub-tropical to temperate latitudes, while the proportion of herbivores declined. This transition was attributed to high sub-tropical benthic productivity and low temperate planktonic productivity in winter.

Location Temperate seas of south-eastern Australia. Methods Mixed data sources synthesized from published accounts, scientific surveys, spearfishing and angling competitions, commercial catches and underwa- ter photographic records, from the ‘late 1800s’ to the ‘present’, were examined to determine shifts in coastal fish distributions. Results Forty-five species, representing 27 families (about 30% of the inshore fish families occurring in the region), exhibited major distributional shifts thought to be climate related. These are distributed across the following categories: species previously rare or unlisted (12), with expanded ranges (23) and/or abundance increases (30), expanded populations in south-eastern Tasmania (16) and extra- limital vagrants (4).

The surveys are part of a series we began in 2007, through which we have aimed to (i) develop a suitable non-destructive technique to search for various uncommon reef fishes (mostly benthic, and many cryptic) throughout South Australia; and (ii) record and photograph such fishes, in order to learn more about their distribution, habitats, and habits. Our target list comprises more than 50 species from 14 families, for which little information is available on full distribution within South Australia, and habitat. Examples of our records during the 2009 survey period included (i) one uncommonly recorded endemic

  • Swan-Avon River System, Western Australia
    Rec. West. Aust. Mus., 1979,8 (1) AN ANNOTATED CHECKLIST OF THE FISHES OF THE SWAN-AVON RIVER SYSTEM, WESTERN AUSTRALIA C.F. CHUBB* J.B. HUTCHINS** R.C.J. LENANTONt and LC.POTTER* lReceived 8 September 1978. Accepted 9 November 1978. Published 30 November 1979.] ABSTRACT The checklIst of the fishes of the Swan-Avon River System in south-western Aust­ ralia given in this paper is based on the collections and records held by the Western Australian Museum, and on the results of a recent extensive samplIng programme carried out with beach seines, trawls and mesh nets. The latter study has also provided data on the distribution of many of the species within the river system. The 110 species recorded are predominantly of marine origin and can be regarded either as marine "stragglers:' or as fish which utilIze the estuary predominantly as a nursery area or adult feeding ground, or as an environment that can be exploited at varIOUS tnnes during the life cycle. Several of the most abundant species are, how­ ever. represented by populations that can pass through the whole of their life cycle within the Swan-Avon River system. Although, as with other south-western AustralIan rivers, the indigenous freshwater fish component is highly impoverished, its abundance in this system has also suffered from the effects ofdamming, periods of "drying-up:' eutrophication and run-off from agricultural land. At the same time, some of the changes brought about by damming have produced conditions favourable fe)r the establishment of populations of certain introduced species. Comparisons between the fish fauna of the Swan-Avon River System and the lImited data for other Western Australian coastal rivers suggest that Cape NaturalIste represents the approximate southern limit of the distribution of many northern species, while the corresponding point for the northwards extension ofseveral southern species is in the region of the North West Cape.

  • Intestinal Microbial Community Composition of Six Actinopterygii
    INTESTINAL MICROBIAL COMMUNITY COMPOSITION OF SIX ACTINOPTERYGII FISH SPECIES IN THE SOUTHEASTERN UNITED STATES by BRIANA LEE RANSOM (Under the Direction of James T. Hollibaugh) ABSTRACT The intestines of fish harbor a microbial community that aids digestion and prevents colonization by pathogens. Traditional methods of studying these communities have been cultivation dependent, yet many microorganisms are difficult to grow in the laboratory. In this study, gut microflora of six different Actinopterygii fish species from the southeastern United States were examined by PCR/DGGE analysis and cloning with primers specific for the 16S rRNA genes of Bacteria. Most fish species seem to have gut microflora dominated by either Firmicutes or proteobacteria. Sequences 92-93% similar to species of Mycoplasma were found in pinfish (Lagodon rhomboides) and red drum (Sciaenops ocellatus), while flounder (Paralichthys lethostigma) contained a majority of sequences most similar to Clostridium spp. The gut microflora of pipefish (Syngnathus scovelli) and silver perch (Bairdiella chrysoura) were dominated by members of the division proteobacteria, and speckled trout (Cynoscion nebulosus) were not dominated by either Firmicutes or proteobacteria.
