First, the ventilation rate of shoaling versus solitary Many animals live in groups because of the potential benefits individuals has been recorded to estimate metabolic rate (Lefrancois associated with defense and foraging.

A second method uses ‘calming effect’ on individuals, reducing overall metabolic demand. respirometry (where oxygen uptake is measured as a proxy for ’ This effect could occur by minimising the need for individual vigilance aerobic metabolism) to compare the sum of each individual s and reducing stress through social buffering.

Roberts, DVM *, Stephen A. Smith, DVM, PhD KEYWORDS Pet fish Ornamental fish Branchitis Gill Wet mount cytology Hypoxia Respiratory disorders Pathology Living in an aquatic environment where oxygen is in less supply and harder to extract than in a terrestrial one, fish have developed a respiratory system that is much more efficient than terrestrial vertebrates. The gills of fish are a unique organ system and serve several functions including respiration, osmoregulation, excretion of nitroge- nous wastes, and acid-base regulation.1 The gills are the primary site of oxygen exchange in fish and are in intimate contact with the aquatic environment. In most cases, the separation between the water and the tissues of the fish is only a few cell layers thick. Gills are a common target for assault by infectious and noninfectious disease processes.2 Nonlethal diagnostic biopsy of the gills can identify pathologic changes, provide samples for bacterial culture/identification/sensitivity testing, aid in fungal element identification, provide samples for viral testing, and provide parasitic organisms for identification.3–6 This diagnostic test is so important that it should be included as part of every diagnostic workup performed on a fish. -

Richards, UBC Zoology Supervisory Committee Member ii Abstract The fish gill is a multipurpose organ that plays a central role in gas exchange, ion regulation, acid-base balance and nitrogenous waste excretion. Effective gas transfer requires a large surface area and thin water-to-blood diffusion distance, but such structures also promote diffusive ion and water movements between blood and water that challenge the maintenance of hydromineral balance. Therefore, a functional conflict exists between gas exchange and ionic and osmotic regulation at the gill. The overarching goal of my thesis was to examine the trade-offs associated with the optimization of these different functions (i.e. -

IR 425 Sampling and Design Options for Monitoring Freshwater Fish
internal report 425 Sampling and design options for monitoring freshwater fish: Potential strategies for the Darwin Harbour catchment B Pidgeon June 2003 supervising scientist Sampling and design options for monitoring freshwater fish: potential strategies for the Darwin Harbour catchment Bob Pidgeon Environmental Research Institute of the Supervising Scientist Darwin Supervising Scientist This talk was presented to the Department of Infrastructure, Planning and Environment, Water Monitoring Branch, in May 2003. It deals with the options for monitoring of freshwater fish in the Darwin Harbour catchment as part of a comprehensive environmental management program for Darwin Harbour being planned by DIPE. It accompanies a report prepared as part of a consultancy by the Environmental Research Institute of the Supervising Scientist to the Department of Infrastructure, Planning and Environment, June 2003. 1 Background • Plans by DIPE to begin monitoring freshwater fish as part of a comprehensive environmental management strategies for Darwin Harbour catchment • Why monitor fish? – Important role in determining structure of aquatic ecosystems – Sensitive to pollution, habitat change and altered hydrology – useful indicators of ecosystem health – High profile of conservation of biodiversity and food and recreation values – Concerns about contamination and human health Supervising Scientist Freshwater fish monitoring in the NT • Not widespread • Most extensive studies are in relation to uranium mining: – in Magela Creek & South Alligator River -Ranger mine; – Finnis River - Rum Jungle mine • Taxonomy is now well known and basic biology and ecology known for many species – good basis for use in monitoring and assessment* • Fisheries research focused on barramundi *The research on fish ecology and reproductive biology by the Office of the Supervising Scientist in 1978-79 (Bishop et al 1986, 1990 & 2002) provides a good basis for the evaluation of impacts on freshwater fish that might be detected in monitoring programs. -

1 CATALOGUE OF PROTOZOAN PARASITES RECORDED IN AUSTRALIA PETER J. O’DONOGHUE & ROBERT D. ADLARD O’Donoghue, P.J. & Adlard, R.D. 2000 02 29: Catalogue of protozoan parasites recorded in Australia. Memoirs of the Queensland Museum 45(1):1-164. Brisbane. ISSN 0079-8835. Published reports of protozoan species from Australian animals have been compiled into a host- parasite checklist, a parasite-host checklist and a cross-referenced bibliography. Protozoa listed include parasites, commensals and symbionts but free-living species have been excluded. Over 590 protozoan species are listed including amoebae, flagellates, ciliates and ‘sporozoa’ (the latter comprising apicomplexans, microsporans, myxozoans, haplosporidians and paramyxeans). Organisms are recorded in association with some 520 hosts including mammals, marsupials, birds, reptiles, amphibians, fish and invertebrates. Information has been abstracted from over 1,270 scientific publications predating 1999 and all records include taxonomic authorities, synonyms, common names, sites of infection within hosts and geographic locations.

Biogeography of Australian Freshwater Fishes
BIOGEOGRAPHY OF AUSTRALIAN FRESHWATER FISHES by Peter John Unmack A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science ARIZONA STATE UNIVERSITY August 1999 BIOGEOGRAPHY OF AUSTRALIAN FRESHWATER FISHES by Peter John Unmack has been approved July 1999 APPROVED: ,Chair Supervisory Committee ACCEPTED: Department Chair Dean, Graduate College ABSTRACT Biogeographic patterns of obligate freshwater fishes of Australia were investigated using museum records. Similarity indices, parsimony analysis, and drainage-based plots of species’ ranges were used to identify patterns. Relationships among regions were deduced largely by concordance between methodologies, which were then summarized into a series of faunal provinces. The most striking pattern was the incidence of endemism across the continent. Provinces in southern, central, and western Australia have high numbers of endemic fishes, presumably as a result of isolation by aridity and drainage divides. With the exception of one region, northern and eastern Australia provinces have few endemics. In the north, this may be explained by high drainage connectivity during times of lowered sea levels. This explanation does not account for low endemism in the east since drainages appear to have been isolated even during lowered sea levels and faunal patterns suggest an absence of distinct barriers of other kinds. By default, climate again seems the most likely cause of species’ distributional limits. Whatever the case, most patterns seem to have been established in the distant past, perhaps as early as Miocene; influences of Plio-Pleistocene events on broader patterns of freshwater fish distributions seem to have been minimal. iii ACKNOWLEDGMENTS I would dearly like to thank my parents, Jean and Stan, for allowing me to pursue my own goals and all their tremendous help and support throughout the years, and my sister Julie for her generous financial assistance. -
