This is a multi-species fishery South Coast Bioregion target various finfish species, mainly targeting many finfish species, with the main fishing methods using trap nets (herring only), beach seines, haul nets and gill being gill net and haul net. The main target species are nets. The main targets are the western species of Australian cobbler (Cnidoglanis macrocephalus), black bream salmon (Arripis truttaceus) and Australian herring (Arripis (Acanthopagrus butcheri), sea mullet (Mugil cephalus) and georgianus), with small quantities of southern sea garfish Australian herring.

Recreational Australian salmon form large migratory schools, particularly Most finfish caught recreationally in South Coast estuaries during the autumn spawning season, that move along the and nearshore waters are taken by line fishing.

Salmon fishing A relatively small amount of recreational net fishing occurs is conducted by teams of fishers setting beach seine nets in the South Coast Bioregion. Recreational net fishing is using either row boats or small jet-powered boats. mainly used to target sea mullet. Most of the commercial catch of Australian herring in WA is taken on beaches along the south coast using herring trap nets (also known as ‘G’ trap nets).

  • The Biology and Ecology of Samson Fish Seriola Hippos

    The Biology and Ecology of Samson Fish Seriola Hippos

    The biology of Samson Fish Seriola hippos with emphasis on the sportfishery in Western Australia. By Andrew Jay Rowland This thesis is presented for the degree of Doctor of Philosophy at Murdoch University 2009 DECLARATION I declare that the information contained in this thesis is the result of my own research unless otherwise cited. ……………………………………………………. Andrew Jay Rowland 2 Abstract This thesis had two overriding aims. The first was to describe the biology of Samson Fish Seriola hippos and therefore extend the knowledge and understanding of the genus Seriola. The second was to uses these data to develop strategies to better manage the fishery and, if appropriate, develop catch-and-release protocols for the S. hippos sportfishery. Trends exhibited by marginal increment analysis in the opaque zones of sectioned S. hippos otoliths, together with an otolith of a recaptured calcein injected fish, demonstrated that these opaque zones represent annual features. Thus, as with some other members of the genus, the number of opaque zones in sectioned otoliths of S. hippos are appropriate for determining age and growth parameters of this species. Seriola hippos displayed similar growth trajectories to other members of the genus. Early growth in S. hippos is rapid with this species reaching minimum legal length for retention (MML) of 600mm TL within the second year of life. After the first 5 years of life growth rates of each sex differ, with females growing faster and reaching a larger size at age than males. Thus, by 10, 15 and 20 years of age, the predicted fork lengths (and weights) for females were 1088 (17 kg), 1221 (24 kg) and 1311 mm (30 kg), respectively, compared with 1035 (15 kg), 1124 (19 kg) and 1167 mm (21 kg), respectively for males.

    The Fish and Fishery of the Swan Estuary

    178 THE FISH AND FISHERY OF THE SWAN ESTUARY N.R. LONERAGAN, I.C. POlTER, School of Environmental and Life Sciences, Murdoch University, Murdoch, Western Australia, 6150 and R.C.J. LENANTON, W.A. Marine Research Laboratories, P.O. Box 20, North Beach, Western Australia, 6020. ABSTRACT A checklist is provided for the fish that have been caught in the Swan estuary. These species each fall into one of the following categories: 1. marine stragglers, 2. marine species which use estuaries extensively at some stage of their life cycle but spawn at sea, 3. estuarine species, i.e. those species which can pass through the whole of their life cycle in the estuary, 4. anadromous species, i.e. those species which migrate from the sea through the estuary to breeding grounds in reduced salinities or fresh water. Examples of different life cycles are provided by reference to mullets (Mugil cephatus and Atdrichetta !orsteri), gobbleguts (A[J()gon ruepel/ii), five species of hardyhead (Atherinidae), Perth herring (Nematatosa vtaminghi) and cobbler (Cnidogtanis macrocephalus). Details are provided (or the commercial fish catches in the Swan estuary and for the recreational fishery for teleosts and prawns. INTRODUCTION Estuaries play an imponant role in the life cycle of many species of fish in temperate regions of both the Northern and Southern Hemispheres (Cronin & Mansueti 1971, Day et al. 1981, Potter et at. 1983, Dando 1984, Claridge et at. 1986). For example, estuaries act as nursery areas for some marine species and as a passage through which I.. catadromous and anadromous species migrate en route to and from their feeding and breeding areas.

The most abundant of the 42 fish species recorded in eight six-weekly samples collected from the nearshore, shallow waters of the basin in 1994, were the long-finned goby Favonigobius lateralis, the sandy sprat Hyperlophus vittatus and the atherinids Leptatherina presbyteroides and Atherinosoma elongata; these four species collectively contributing 83.0% to the total number of fish caught. Of the 42 species, 20 were marine species which use the estuary as a nursery area (marine estuarine-opportunists), while 13 complete their life cycles in the estuary, of which seven are also represented by marine populations. The contribution made to the total number of individuals by marine estuarine-opportunists and marine stragglers collectively (32.1%) was far lower than that of species which complete their life cycles in the estuary (67.9%).
