...Simon Kaminskas ABSTRACT Native freshwater fish of Australia have a diverse but largely undescribed endemic pathogen and parasite fauna. However, due to long-shared evolutionary histories and virulence/transmissibility trade-offs, effects of these endemic pathogens and parasites appear to be subtle...

...P. G. Parker A survey of fish species occurring in the marine waters of northern New South Wales was conducted at five sites between October 1988 and February 1996. The principal study site was at Julian Rocks, located approximately five km north of Cape Byron, Australia's most easterly mainland...

...L. A. Morgan; W. A. Buttemer Gambusia holbrooki, the “Mosquito Fish” introduced to Australian waterways from North America to control mosquito larvae, is widely distributed and abundant in both disturbed and undisturbed aquatic environments. Because it has become established in areas where Litoria...

...R. A. Faragher; J. H. Harris Examples are given of a number of New South Wales freshwater fish species which have declined in abundance since last century. Reasons for the declines include river regulation, changes to riparian vegetation, erosion and siltation. The effects of alien species...

...Cameron Webb; Jean Joss Gambusia holbrooki is a small, aggressive fish introduced into Australia in 1925 to control mosquitoes. It has been suggested that this species may also prey on tadpoles and be a contributing factor in the decline of some Australian frog populations. We examined...

...R. Lardner; Walter Ivantsoff; Lucy E. L. M. Crowley An intertidal rock pool at Seal Rocks, New South Wales, was repeatedly defaunated during summer or autumn between 1969 and 1987 using the ichthyocide rotenone. The fish assemblage was of moderate diversity, dominated by juveniles of subtidal...

...Greg Maguire; J.D. Bell A diverse fish fauna (49 species) was recorded in four tidal 0.11 ha prawn farming ponds which appear to act as fish traps. The potential deleterious effects of twelve of these species on prawn growth or survival are discussed in terms of the diet and reproductive biology...

...L. Llewellyn Length - weight relationships for 29 fish species occurring in the Murray-Darling River System in inland NSW were determined using data collected principally between 1957 and 1970. In Golden Perch Macquaria ambigua , this relationship is examined with regard to locality, year and sex...

... minutes did not. Positive correlations were found between set time and both overall (fish/trap) and standardised (fish/trap/ minute) catch rates, although only the former relationship was significant. The addition of bait to traps did not significantly affect catch rates. Trapping, seine netting...

... generally; I have a very interesting collection of freshwater fishes and shells. On crossing the Plains from Gande . . . (69), 1 met with the Peristera histrionica (70) in prodigious numbers, some few of them were breeding, I found several pairs of eggs, laid on the bare ground, under the shade of a clump...
