  • Relationships Between Faunal Assemblages and Habitat Types in Broke Inlet, Western Australia
    Relationships between faunal assemblages and habitat types in Broke Inlet, Western Australia Submitted by James Richard Tweedley This thesis is presented for the degree of Doctor of Philosophy 2010 B.Sc (Hons) University of Portsmouth (UK) MRes University of Plymouth (UK) Declaration I declare that the information contained in this thesis is the result of my own research unless otherwise cited, and has as its main content work which has not previously been submitted for a degree at any university. __________________________________________ James Richard Tweedley Shifting Sands: The sand bar at the mouth of Broke Inlet in (top) summer and (bottom) winter 2008. Bottom photo by Bryn Farmer. Abstract The work for this thesis was undertaken in Broke Inlet, a seasonally-open estuary on the south coast of Western Australia and the only estuary in that region which is regarded as “near-pristine” (Commonwealth of Australia, 2002). The only previous seasonal studies of the environmental and biotic characteristics of this estuary involved broad-based descriptions of the trends in salinity, temperature and ichthyofaunal characteristics at a limited number of sites. Furthermore, no attempt has been made to identify statistically the range of habitats present in the nearshore and offshore waters of this system, and the extents to which the characteristics of the fish and benthic invertebrate faunas are related to habitat type. These types of data provide not only reliable inventories of the habitat and faunal characteristics of Broke Inlet, but also a potential basis for predicting the likely impact of anthropogenic and climatic changes in Broke Inlet in the future.

  • Fishes of the King Edward River in the Kimberley Region, Western Australia
    Records of the Western Australian Museum 25: 351–368 (2010). Fishes of the King Edward River in the Kimberley region, Western Australia David L. Morgan Freshwater Fish Group, Centre for Fish and Fisheries Research, Murdoch University, Murdoch, Western Australia 6150, Australia. E-mail: [email protected] Abstract – The King Edward River, in the far north of the Kimberley region of Western Australia drains approximately 10,000 km2 and discharges into the Timor Sea near the town of Kalumburu. This study represents an ichthyological survey of the river’s freshwaters and revealed that the number of freshwater fishes of the King Edward River is higher than has previously been recorded for a Western Australian river. Twenty-six strictly freshwater fish species were recorded, which is three species higher than the much larger Fitzroy River in the southern Kimberley. The study also identified a number of range extensions, including Butler’s Grunter and Shovel-nosed Catfish to the west, and the Slender Gudgeon to the north and east. A possibly undescribed species of glassfish, that differs morphologically from described species in arrangement of head spines, fin rays, as well as relative body measurements, is reported. A considerable proportion of Jenkins’ Grunter, which is widespread throughout the system but essentially restricted to main channel sites, had ‘blubber-lips’. There were significant differences in the prevailing fish fauna of the different reaches of the King Edward River system. Thus fish associations in the upper King Edward River main channel were significantly different to those in the tributaries and the main channel of the Carson River.

  • Catch and Effort Data
    Chapter 11: The Inland Waters River Fishery Information System CHAPTER 11: INLAND WATERS RIVER FISHERY INFORMATION SYSTEM 11.1 Background The Inland Waters River fishery is a multi-species, multi-gear fishery encompassing the South Australian sector of the River Murray and its backwaters (Map 11.1). Historically, the fishery was based on harvesting Murray cod (Maccullochella peelii peelii), golden perch (Macquaria ambigua), and bony bream (Nematalosa erebi). The fishery was restructured in July 2003 to a non-native dominate fishery and the commercial fishing for significant native species is now prohibited. The fishery is now based predominantly on the taking European carp (Cyprinus carpio) and redfin perch (Perca fluviatilis). There are a total of 6 licence holders who operate within the fishery. Prior to the restructure 30 license holders fished the river, each with a designated reach. Up to December 2007 SARDI production tables hold in excess of 270,000 daily records. Data is held from 1984/85 to current and is continually being updated. Refer to Figure 11.3 for an entity relationship diagram of the inland waters system that encompasses the River Fishery.

  • A New Freshwater Catfish (Pisces: Ariidae) from Northern Australia
    Rec. West. Aust. Mus. 1988,14(1): 73-89 A new freshwater catfish (Pisces: Ariidae) from northern Australia PatriciaJ. Kailola* and Bryan E. Pierce* Abstract A new species of fork-tailed catfish is described on the basis of 31 specimens collected in northern Australia between the Fitzroy River (Western Australia) and the Mitchell River (Queensland). Arius midgleyi sp. novo grows to at least 1.3 m TL and is distinguished from other Australo-Papuan ariids by a combination of charac­ ters including snout shape, barbel length, eye size, tooth arrangement and gill raker number and position. Comparison is made with other ariid species occurring in northern Australian rivers, including the morphologically similar A. leptaspis (Bleeker). Introduction The Timor Sea and Gulf of Carpentaria drainage systems (Lake 1971) approx­ imately represent the Leichhardtian zoogeographic region of Whitley (1947). The rainfall pattern in this region is dominated by the wet monsoon (occurring within the period November to April). Most rivers here traverse a flat coastal plain about 15 km wide before reaching the sea (Lake 1971). These rivers commonly possess wide flood plains and low gradients, often contracting to a chain of waterholes during the dry season; some (Gregory River; Fitzroy to Daly Rivers) have reaches of rapids or very deep gorges. The average annual discharge from this region is 69000 billion litres (Lake 1971), most of it occurring during the wet season. Five of Australia's 18 species of fork-tailed catfishes (Ariidae) are common in this northern region, yet were overlooked by Whitley (1947) and Iredale and Whitley (1938). The members of this family, which is distributed circumglobally in the tropics and subtropics, may inhabit the sea, rivers within tidal influence, or fresh waters.

  • Tristan Da Cunha Fisheries Detailed Report 2017
    Tristan da Cunha The Tristan da Cunha Archipelago is a group of volcanic islands in the South Atlantic (37o-41 o S; 9o-13o W), which includes the main island of Tristan da Cunha (96 km2), Gough Island (65 km2), Inaccessible Island (14 km2), Nightingale Island (3 km2) and two small islands close to Nightingale. The island group is situated around 1200 nautical miles south of St Helena and 1500 miles WSW of Cape Town, South Africa (Figure TdC-1). The island is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, with the Governor based on St Helena. The Administrator is the Governor’s representative on Tristan da Cunha. Figure TdC-1. The South Atlantic Ocean showing the location of the Tristan da Cunha island group. The three northern islands (Tristan, Nightingale and Inaccessible) lie north of the Subtropical Convergence STC), a circumpolar oceanic front located at approximately 42˚S where the sea surface temperature (SST) drops sharply. Gough Island lies in the path of the STC, which moves north of the island during winter months. Average SST at Tristan da Cunha in the austral summer range from 15- 19˚C, and in winter it declines to 13-15˚C. At Gough Island SST is on average 3˚C cooler than at the Tristan group during all months. The tidal range is small, but trade winds and frequent storms means that the marine environment is high energy with frequent physical disturbance. The Tristan da Cunha 200 nautical mile Exclusive Fishing Zone (EFZ; Figure TdC-2) was established in 1983 and covers an area of 754,000 km2.

  • Effects of Salting and Drying on Quality Attributes of Snoek (Thyrsites Atun)
    Effects of salting and drying on quality attributes of snoek (Thyrsites atun) by Tanimowo Esther Omolara Thesis presented in partial fulfilment of the requirements for the Degree Master of Food Science at Stellenbosch University Supervisor: Prof. Louw Hoffman Co-supervisor: Prof. Umezuruike Linus Opara, Dr. Bernadette O’Neill March, 2015 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own original work, that I am the single author thereof (except to the extent explicitly otherwise stated) and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March, 2015 Copyright © 2015 Stellenbosch University of Stellenbosch All rights reserved ii Stellenbosch University https://scholar.sun.ac.za Abstract Snoek (Thyrsites atun) is an important commercial fish species in South Africa, particularly in the Western Cape province. Snoek is mainly sold as fresh fish with excess fish being processed into dried salted fish. Although fishing is regulated by the various government agencies, the processing chain of snoek is largely unmonitored and unstandardized which has resulted in variable snoek quality becoming available to the consumer. Therefore, the aim of this study was to assess the quality (proximate, biochemical composition and microbiological safety) of salted and dried snoek products both experimentally and through market sampling. This was achieved by investigating two lines of research: 1) Establishing the quality of locally sold salted and dried snoek from informal vendors and 2) Investigating the effects of different levels of salting (%) and drying (relative humidity and temperature) conditions on snoek meat quality.

    15 Islands 15.2 Sand Islands and Shoals Figure 15.1: (A) Aerial view of Troubridge Island and surrounding Troubridge Shoals: (c) Coastal Protection Branch, DEWNR. (B). Troubridge Island: (c) W. Bonham, Lighthouses of Australia. Asset Sand Islands and Shoals Description A crest of sand which rises above water level from a broad marine sand bank, forming an unstable sand island - Troubridge Island - which changes shape and size over time. The island is about 5m high at high tide, and about 2 hectares in area when inundated, but considerable larger at low tide. The island is surrounded by shallow sand embankments (Troubridge Shoals). Examples of Key Little Penguin, Black-faced Cormorant, Crested Tern and other breeding sea Species birds (numerous species) migratory wading birds (numerous species) abundant sand-dwelling invertebrates - food sources for fish and wading birds Pink Snapper King George whiting and school whiting syngnathid fishes (e.g. seahorses, pipefishes) sponges (forming “sponge gardens”, on consolidated sand) cowries; volutes and other specimen shells Knobby Argonaut (‘paper nautilus’ octopus) giant spider crab southern calamari Main Location Troubridge Island (and shallow sandbanks to the west - Troubridge Shoals) Notes Troubridge Island Conservation Park (approx. 260 hectares) was declared in 1982, and extended in 1986, partly to protect major breeding colonies of several seabird species, and provide protection for an important feeding ground used by migratory wading birds, listed under international treaties. Oceanography At the bottom of Gulf St Vincent, off the eastern “heel” of Yorke Peninsula, waters less than 20m occur up to 10km from shore. The oceanographic conditions have led to a long-term build-up of sand in some areas, including the creation of Troubridge Island, a sand island about 7km east of Sultana Point.
