This Management Paper is intended to assist the Executive Director when considering the issuing of authorisations for commercial aquaculture under Section 92 of the Fish Resources Management Act 1994; written approvals or written authorities for the translocation of barramundi under Regulation 176 of the Fish Resources Management Regulations 1995; and in the development of programs for recreational fishery enhancement of barramundi. It is also designed to provide guidance to the aquaculture industry and recreational fishing groups when considering the farming or stocking of barramundi in this State.

Intertidal Benthic Resources Of The Copper River Delta, Alaska, Usa, Sean Powers, Mary Anne Bishop, Jonathan H. Grabowski, Charles H. Peterson

University Faculty and Staff Publications

The Copper River Delta, Alaska is the largest contiguous coastal wetland system along the West Coast of North America. Vast expanses of tidal mud flats formed by sediments carried by the suspended load of the Copper River serve as a connection between the Gulf of Alaska and the extensive network of wetlands, rivers and sloughs of the delta system. In addition to providing habitat for resident fish, shrimp and crabs, these tidal flats serve as critical feeding grounds for up to 5 million migratory shorebirds as well as an entry and exit corridor for three species of commercially fished salmonids. …

Fisheries Research Report No.131 - Pilchard (Sardinops Sagax) Nursery Areas And Recruitment Process Assessment Between Different Regions In Southern Western Australia, Daniel J. Gaughan, Graeme Baudains, Ronald W. Mitchell, Timothy I. Leary

Fisheries Research Reports

Pilchards have been the primary target of purse seine fisheries along the south and lower west coasts of WA for nearly 15 years. Western Australia’s pilchard population consists of separate west coast and south coast breeding stocks. The adult pilchards in the south coast stock can, in turn, be further divided into three separate assemblages. These adult assemblages correspond to the purse seine fisheries at Albany, Bremer Bay and Esperance. However, while the separateness of the adult assemblages is well established, the status of the juveniles within the context of these adult groups is not understood. For example, the habitats …

Effects Of Fish Cage Aquaculture On The Zooplankton In A Malaysian Mangrove Estuary, Ai Lin Ooi

Student Works (2000-2009)

A study on the effects of fish cage aquaculture on the zooplankton was carried out in the Matang mangrove estuary, Perak, Malaysia. Investigations consisting of 4-month study and 12-hour study were conducted. Zooplankton were sampled inside and away from floating fish cage culture areas in Sangga Besar (SSB) river and in an adjacent nonaquaculture river, Sangga Kecil (SSK), in order to examine the effect of fish cage culture on zooplankton abundance. Zooplankton populations varied both spatially (being more abundant towards the river mouth) and temporally (being more abundant at certain months, e.g. in December). In SSB, fish cage culture had …

Fisheries Research Report No. 136 - Assessment Of Gonad Staging Systems And Other Methods Used In The Study Of The Reproductive Biology Of Narrow-Barred Spanish Mackerel, Scomberomorus Commerson, In Western Australia, Michael C. Mackie, Paul Lewis

Fisheries Research Reports

Recent research by the Department of Fisheries in Western Australia into the reproductive biology of narrow-barred Spanish mackerel has required the use of various field and laboratory techniques. This report documents the procedures and adaptations of some of these techniques. Assessment and development of illustrated, relevant macroscopic and microscopic staging systems were of particular focus because both have been essential components of the research. The simplified and more reliable macroscopic staging system we developed allowed full use of all gonad samples and a more complete (albeit less distinct) overview of the seasonal pattern of gonad reproductive development. This macroscopic staging …

Fisheries Research Report No.128 - Aquaculture And Related Biological Attributes Of Abalone Species In Australia - A Review., Kylie A. Freeman

Fisheries Research Reports

China and Taiwan are the major producers of cultured abalone; with annual production estimated at 3,500 and 3,000 tonnes respectively. The world production of cultured abalone sold in 1999 was 7,775 tonnes. Australian farm production was still relatively low (89 tonne in 1999) but numerous abalone farms have been proposed and many have been constructed. On a national scale, Tasmania and South Australia are the major states involved in temperate abalone culture; however, new projects have commenced in Victoria and considerable interest exists in New South Wales. Pilot scale trials with tropical abalone aquaculture using the Donkey-ear abalone (Haliotis asinina) …

The Links Between Functionally Distinct Adult Assemblages Of Sardinops Sagax : Larval Advection Across Management Boundaries, Daniel J. Gaughan, K V. White, Warrick (Rick) J. Fletcher

Fisheries Research Articles

Otolith increment data were used to age larval Sardinops sagax collected from shelf waters between Kangaroo Island in South Australia (SA) and Albany in Western Australia (WA). Distributions of both ages and hatch-dates were compared between six regions across this broad area to examine the hypothesis that larvae arising from spawning sardines in WA may be advected by the Leeuwin Current to the central coast of SA prior to metamorphosis. Current and wind data were analysed to estimate potential rates of passive transport. It appears likely that larvae arising from commercially exploited S. sagax populations in WA can be passively …

Fisheries Research Report No. 125 - A History Of Foreign Fishing Activities And Fishery-Independent Surveys Of The Demersal Finfish Resources In The Kimberley Region Of Western Australia, G Nowara, Stephen J. Newman

Fisheries Research Reports

The aim of this project was to collate all historical information regarding fishing activities relevant to the Northern Demersal Scalefish Fishery. Three primary sources of information were identified; foreign Taiwanese pair-trawl fishing activities; traditional Indonesian fishing activities; and fishery-independent (CSIRO) survey data.

The Taiwanese pair-trawl fishing catch and effort from 1980 to 1990 was concentrated into two main regions, the Broome area (120°-122°E) and the Holothuria Banks area (124°-126°E) in the north. The majority of trawls were undertaken in the mid-continental shelf region (60-100 m). The total catch of these vessels reached a peak of 4,394 tonnes in 1985. Effort …

Fisheries Occasional Publication No. 31 - Feeding Lupins To Fish: A Review Of The Nutritional And Biological Value Of Lupins In Aquaculture Feeds, Brett Glencross

Fisheries Occasional Publications

Lupins are the harvested seed of species from the Lupinus genus, a group within the leguminous bean and pea family Fabaceae. Legumes are particularly valuable agricultural crops because of their capacity to provide a grain crop and also fix and return nitrogen to soils and improve the soil value for further cropping. The oilseeds, soybeans and peanuts are also leguminous plants, though traditionally they have been cropped for their oil value, whereas lupins, are cropped for both their protein and nitrogen fixing value (Gladstones, 1998; Perry et al., 1998).

The three key commercial species of lupins are L. angustifolius (Narrow-leafed …

The 6th International Conference And Workshop On Lobster Biology And Management: An Introduction, Mark J. Butler Iv

Biological Sciences Faculty Publications

Every three years or so, the International Conference and Workshop on Lobster Biology and Management (ICWL) brings together lobster scientists, fishery managers, and industry representatives from around the world for a week of scientific presentations, workshops, and discussions on lobster biology and management. The first ICWL was held in Perth, Australia, in January 1977. Its purpose was to bring together a small group of lobster researchers from the USA and Australia to discuss common issues and themes. That initial workshop spawned a continuing series of meetings that have become the international lobster conference for scientists—the equivalent of an international congress …

Growth Rate Variability And Lipofuscin Accumulation Rates In The Blue Crab Callinectes Sapidus, Se-Jong Ju, David H. Secor, H. Rodger Harvey

OES Faculty Publications

To better understand growth and age-pigment (lipofuscin) accumulation rates of the blue crab Callinectes sapidus under natural conditions, juveniles (33 to 94 mm carapace width) were reared in outdoor ponds for over 1 yr. Growth rates, measured by carapace width, during summer and fall exceeded all those reported in the literature; the initial carapace width of 59 ± 14 mm (mean ± SD) increased to 164 ± 15 mm within a 3 mo period. No growth occurred during winter months (November to April) at low water temperatures. Growth rates of crabs in ponds were substantially higher (von Bertalanffy growth parameter …

Fisheries Research Report No. 123 - Review Of Productivity Levels Of Western Australian Coastal And Estuarine Waters For Mariculture Planning Purposes, Alan Pearce, Stuart Helleren, Mark Marinelli, Fisheries Western Australia

Fisheries Research Reports

The measurement of chlorophyll-a (a simple estimate of phytoplankton biomass) is often used as an indicator of water quality. Chlorophyll measurements are relatively sparse for most of the Western Australian continental shelf, although there are areas such as the Perth metropolitan coastal zone, Wilson Inlet and the Albany harbours where some intensive studies have been undertaken.

This review of both published and unpublished chlorophyll concentrations in Western Australian waters has shown a high degree of variability in space (both horizontally and vertically) and time, and statistics on the seasonal distribution of chlorophyll have been derived for those regions with sufficient …

Fisheries Research Report No. 124 - The Evaluation Of A Recreational Fishing Stock Enhancement Trial Of Black Bream (Acanthopagrus Butcheri) In The Swan River, Western Australia, C J. Dibden, G. Jenkins, Gavin A. Sarre, R C J Lenanton, Suzanne G. Ayvazian

Fisheries Research Reports

During 1995, a study was undertaken to monitor and evaluate the recovery of Swan River black bream stock which had been supplemented with fish produced from a captive-breeding program. Fish were individually tagged and subsequently released into the Swan River. The objectives of the study were (a) to determine both the survival and the growth rate to a size at which hatchery-reared fish could enter the recreational fishery and (b) whether they could then be caught by the recreational fishers. Of the 767 fish released into the upper Swan River on 28 March 1995, 97 fish (12.6%) were recaptured to …

Effects Of Blood Extraction On The Mortality Of The Horseshoe Crab, Limulus Polyphemus, Elizabeth A. Walls, Jim Berkson

Virginia Journal of Science

Horseshoe crabs (Limulus polyphemus) are bled by biomedical companies for the extraction of Limulus Amoebocyte Lysate (LAL), a clotting agent used in the detection of endotoxins. In 1998, the Atlantic States Marine Fisheries Commission mandated that all biomedical companies collecting horseshoe crabs for the production of LAL study the horseshoe crab mortality rates resulting from the company's blood extraction process. BioWhittaker, a Cambrex Company is one of the largest producers of LAL in the world. During the summer of 1999, bled and unbled horseshoe crabs were transported from BioWhittaker's bleeding facility in Chincoteague, Virginia to the Virginia Seafood …

Biological And Physical Observations On Larval Spot (Leiostomus Xanthurus) Recruiting To Oregon And Ocracoke Inlets North Carolina, Thomas R. Wasaff

Biological Sciences Theses & Dissertations

Patterns of abundance, length, age, and growth of larval spot (Leiostomus xanthurus) were compared to assess the variability between spot larvae ingressing to two North Carolina inlets. The source of variability for the recruitment of larval fishes to estuarine nurseries has been linked to environmental stochasticity. Wind data and seasurface temperature satellite images were analyzed as two influential environmental variables that may help explain recruitment variability. As part of the South Atlantic Bight Recruitment Experiment (SABRE), spot larvae were collected between October 1994 and April 1995 as they recruited to Pamlico Sound through Oregon Inlet, located north of Cape Hatteras, …

Fisheries Research Report No. 121 - Synopsis Of The Biology And Exploitation Of The Blue Swimmer Crab, Portunus Pelagicus Linnaeus, In Western Australia, Mervi I. Kangas

Fisheries Research Reports

This report summarises the existing studies which have provided information on the biology, population characteristics and exploitation of the blue swimmer crab, Portunus pelagicus, in Western Australia. Gaps in the existing knowledge are also highlighted to assist in targeting new research initiatives. Portunus pelagicus matures at about one year and in temperate regions females mate only once a year. This is because mature crabs moult only once a year. It appears from studies to date that Western Australian crabs are one genetic population. This is being further investigated. Migration of the blue swimmer crab occurs between estuaries and the ocean …

Comparison Of Larval Myomere Counts Among Species Of Nocomis In Virginia (Actinopterygii: Cyprinidae), Terre D. Green, Eugene G. Maurakis

Virginia Journal of Science

Larval myomere counts of Nocomis platyrhynchus were made using a dissecting light microscope equipped with polarizing filters, and then compared to those of the three other species of Nocomis (Nocomis leptocephalus, Nocomis micropogon, and Nocomis raneyi) found in Virginia. Average preanal myomere counts for N. platyrhynchus (26.9) were significantly different from those of the other three species (N. raneyi =28.7; N. micropogon =26.0; and N. leptocephalus =25.9). This is especially important as larvae of N. leptocephalus, the only other species of Nocomis syntopic with N. platyrhynchus in the upper New River drainage, can now …

Feeding Habits Of Young-Of-Year Striped Bass, Morone Saxatilis, And White Perch, Morone Americana, In Lower James River, Va, Paul J. Rudershausen, Joseph G. Loesch

Virginia Journal of Science

A total of 188 young-of-year (YOY) striped bass, Morone saxatilis, and 199 YOY white perch, Morone americana, were collected by pushnet, seine and trawl during 24-hour periods from June through August, 1992 in lower James River, Virginia. The purpose was to identify prey and temporal and spatial feeding habits. Copepods were the most numerous prey of both species. Fishes and mysids comprised the largest volumetric percentage of diets of striped bass and white perch, respectively. Using an index of relative importance, leptodorids and copepods were the most important prey of striped bass and white perch, respectively. Both species …

Fish Health For Fish Farmers - 2nd Edition, Tina Thorne

Fisheries Published Reports

2nd edition.

Disease is a departure from the normal state of health of a fish or any other animal. Diseases have no doubt occurred among fishes since these animals have occupied a place on the earth. Scientific efforts to understand the causes of disease in fishes, and to attempt to control them however, have only been made during the last sixty years.

Fishes, crustaceans and molluscs, as with other animals are subject to a wide spectrum of diseases, that can be classified as infectious or non-infectious. The vast majority of disease problems in the intensive farming of aquatic animals can …

Ontogeny, Reproduction, And Population Dynamics Of Stoplephorus Baganensis And Thryssa Kammalensis (Pisces : Engraulididae) In A Malaysian Estuary Sarpedonti, Valerie, Valerie Sarpedonti

Student Works (2000-2009)

Larval ontogeny of Stolephorus baganem:;is and Thryssa kammalensis, comprises three successive phases characterized by: (I) development of swimming appendages, (2) changes in allometric growth of various body parts, and (3) increase in body depth, as well as eye diameter, in the case of S. baganensis. Both anchovy species are multiple spawners, spawning all year round but varying in intensity. Mass spawnings of S bagane11sis start in the first (summer) inter-monsoon period and last for four months. This period is associated with changes in the wind field and increased rainfall, dissolved oxygen and food availability. The presence of mature adults during …

Department Of Fisheries Annual Report Highlights 1999 - 2000, Department Of Fisheries, Western Australia

Department of Fisheries Annual Reports

1999/2000 has marked a 'sea change' in fisheries management throughout Australia towards the principles of Ecologically Sustainable Development (ESD). This is a dynamic concept with an evolving framework that requires a balancing of social, economic and environmental considerations.

The principles of ESD - of using, conserving and enhancing the community's resources so that ecological processes, on which life depends, are maintained, and the total quality of fisheries, now and in the future, can be increased - are vital in a state, national and international context for Fisheries WA and its clients. Having fisheries that are governed under ESD principles is …

Syncoelium Vermilionensis Sp. N., (Hemiuroidea: Syncoeliidae) And New Records For Members Of Azygiidae, Ptychogonimidae, And Syncoeliidae Parasitizing Elasmobranchs In The Gulf Of California, Stephen S. Curran, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During July-September 1993 and May 1996, a survey of the metazoan parasites of 817 elasmobranchs from the Gulf of California, representing 42 species, was conducted at 14 sites along the western portion of the Gulf of California. Elasmobranchs were obtained from local commercial fishers. In this paper, we report all digeneans collected during the survey, excluding the gorgoderids, which will be presented in a subsequent paper. Four species from three hemiuroid families were collected, none of which was known previously from the Gulf of California. Syncoelium vermilionensis sp. n.

Review Of The Western Australian Pilchard Fishery 12 -16 April 1999, K. L. Cochane

Fisheries Management Papers

A workshop was held on Monday 12 April 1999 at which presentations were made by representatives of Fisheries WA, speakers from other state fisheries agencies and the Western Australian (WA) pilchard industry. This workshop identified some of the key concerns in the assessment and management of the fishery. This report presents the conclusions reached by the reviewer at the end of the process, which were also presented to members of the WA pilchard fishing industry in Albany on Friday 16 April.
