Draft Aquaculture Plan For Shark Bay., Department Of Fisheries
Draft Aquaculture Plan For Shark Bay., Department Of Fisheries
Fisheries Management Papers
The Department of Fisheries has prepared this draft aquaculture plan for Shark Bay to provide an agreed framework for future management of aquaculture. The final plan will assist prospective aquaculturists in preparing proposals and will guide the Department of Fisheries in the decision making process for aquaculture licence and lease applications. The plan identifies constraints to aquaculture development and areas where aquaculture may occur. It also identifies species that may be used for aquaculture development. Implementation of this plan will ensure that aquaculture can occur in a sustainable manner, while retaining the unique features of Shark Bay.

What is a gonad?
"Gonad" is a general term for a reproductive organ, and is used to describe both ovaries and testes. In male and female fish, the gonad is an elongated organ lying along the upper wall of the gut cavity (i.e. running immediately under the vertebral column). The gonad gonad has 2 lobes. Both lobes are attached to the body near the anus and extend forward inside the gut cavity.
As fish gonads ripen, they become larger, heavier and change colour. Immature and undeveloped adult gonads are very small, strap-like in shape, pinkish in colour and translucent (i.e. …

The overall objective of the proposed FHPA and the associated Plan of Management is to conserve and protect a portion of the near-shore reef ecosystem in the vicinity of the Blue Holes, and to manage activities within the area, to promote the observation and protection of fish living within the area. Strong community commitment has already been demonstrated, and this is crucial in the implementation of the proposed management plan
Fish Stock And Fishery Enhancement In Western Australia. A Summary Report., Department Of Fisheries
Fish Stock And Fishery Enhancement In Western Australia. A Summary Report., Department Of Fisheries
Fisheries Management Papers
This summary paper provides an overview of the key proposals set out in the full policy discussion paper, Fisheries Management Paper No 175. It does not discuss the theoretical background for the framework presented and therefore readers interested in such discussion are directed to Fisheries Management Paper No 175.
Both papers have been prepared to encourage public involvement in the development of policy for stock enhancement within Western Australian waters. Stock enhancement can involve an existing fishery or creation of a new fishery through the translocation of fish. It affects both public and private waters.

Fisheries Research Report No. 146 - Catch Composition Of The Western Australian Temperate Demersal Gillnet And Demersal Longline Fisheries, 1994 To 1999, Rory Mcauley, Colin Simpfendorfer
Fisheries Research Reports
Catch composition data were collected from Western Australia’s temperate demersal gillnet and demersal longline fisheries, between Eucla and Geraldton, over a five-year period from July 1994 to June 1999. Results were compared to Department of Fisheries catch records compiled from fishers’ monthly catch returns. Discarded bycatch of several species was estimated by bootstrapping their observed catch rates. Dusky shark, Carcharhinus obscurus, gummy shark, Mustelus antarcticus, whiskery shark, Furgaleus macki, and Port Jackson shark, Heterodontus portusjacksoni, were identified as the main components of the fisheries’ catch, however, catches were found to vary regionally. School shark, Galeorhinus galeus, dogfish of the family …

Fisheries Research Contract Report No. 6 - Assessment Of The Nutritional Variability Of Lupins As An Aquaculture Feed Ingredient, Brett Glencross, John Curnow, Wayne Hawkins
Fisheries Research Reports
The nutritional value of the kernel meals of three species of lupin (Lupinus albus, L. angustifolius and L. luteus) was compared against each other and a reference ingredient of solvent extracted soybean meal, when fed to rainbow trout (Oncorhynchus mykiss). Each lupin kernel meal was included in test diets at 300 g/kg and also at a greater level, representing 50% of the total protein content in the diet. The digestibility of protein of all lupin kernel meals was better than for the soybean meal. The highest protein digestibility was that from L. luteus kernel meal at 30% inclusion (100%), which …

Fisheries Research Contract Report No. 4 - Determining Waste Excretion Parameters From Barramundi Aquaculture: Final Report For Aquaculture Development Fund Of Wa, Brett Glencross, Neil Rutherford, Wayne Hawkins
Fisheries Research Contract Reports
This study was undertaken to evaluate the nutrient excretion budgets for each of three key commercial diets when fed to barramundi (Lates calcarifer). The diets differed primarily in their energy density ranging from 21.3 MJ/kg DM to 23.0 MJ/kg DM, with the protein content of each diet being relatively constant at around 550 g/kg DM. The determination of the nutrient excretion budgets required the assessment of the digestibilities of key nutrients from each of the diets and also the specific retention of nutrients over a prolonged period. This necessitated two digestibility trials and a growth trial.
An examination was also …
The Effects Of The Trawl Fishery On The Stock Of Pink Snapper, Pagrus Auratus, In Denham Sound, Shark Bay, M. Moran, M. I. Kangas
The Effects Of The Trawl Fishery On The Stock Of Pink Snapper, Pagrus Auratus, In Denham Sound, Shark Bay, M. Moran, M. I. Kangas
Fisheries Research Bulletins
Snapper stocks in the inner gulfs of Shark Bay are in a depleted condition, both in trawled and non-trawled areas, with the main factor contributing to the depletion considered to be recreational fishing for adult snapper, including some mortality of undersized snapper returned to the water. The commercial prawn trawl fishery catches many small fish species, including small juvenile pink snapper, as part of its unintended bycatch. Some members of the local community believe that mortality of juvenile snapper due to trawling has also been a significant factor in depletion of the adult stock in Denham Sound, Shark Bay. While …
Fisheries Research Contract Report No. 3 - Early Life History Of Abalone (Haliotis Rubra, H. Laevigata): Settlement, Survival And Early Growth. Final Report For Frdc Project 1998/306, Dr Sabine Daume
Fisheries Research Contract Reports
Australian abalone fisheries produce a high value, export-orientated products that provided 60% of the world supply in 1994 (Fleming, 2000). With wild abalone fisheries declining in countries worldwide, the interest in aquaculture products has increased substantially. The world production of abalone from aquaculture in 1999 was approximately 7,775 tonnes with only 89 tonnes (ca. 1%) being produced in Australia (Fleming, 2000). Abalone farming is expected to develop into a major industry and is a significant investment opportunity (McNamara, Victorian Aquaculture Strategy, May 1997). Future production from the numerous farms and sites either established, under construction or approved in Australia, could …

Draft Plan Of Management For The Proposed Point Quobba Fish Habitat Protection Area., Department Of Fisheries
Fisheries Management Papers
Point Quobba is a popular site for locals and tourists for beach activities, fishing and snorkelling, and as a place for children to learn to swim and gain an awareness of the marine environment. The marine life and habitats of the area are of considerable scientific and recreational interest and are highly valued in the local community. However, they are at risk from their high level of use and from conflict between users due to their proximity to popular tourism, boat ramp, camping and settlement areas on-shore.

Fisheries Occasional Publications
Determining the relative priority for research proposals within an agency such as the Department of Fisheries, particularly when they are from different program areas, is a difficult task to achieve effectively. Traditionally within the Department, this task has been completed by a sub-group of the executive who have used their combined understanding of the broader issues and their experience of what has been done before and what is most likely to succeed. Such a system, while it has produced satisfactory outcomes, suffers from a lack of transparency and may be at longer-term risk when personnel changes occur and corporate knowledge …

Final Report for FRDC Project 2001/061
Pink snapper (Pagrus auratus) is the main commercial and recreational finfish (Kailola et al., 1993) in the Shark Bay region. Pink snapper are distributed along much of the temperate and tropical coasts of Western Australia from east of Esperance on the south coast to north of Shark Bay on the west (Paulin 1990). Previous research using genetics (Johnson et al. 1986), tagging (Moran et al. 2004), and otolith microchemistry (Edmonds et al., 1989, 1999) have shown that pink snapper from the innermost parts of Shark Bay do not mix with the ocean fish

Fisheries Research Report No. 143 - Methods Used In The Collection, Preparation And Interpretation Of Narrow-Barred Spanish Mackerel (Scomberomorus Commerson) Otoliths For A Study Of Age And Growth In Western Australia, Paul Lewis, M. C. Mackie
Fisheries Research Reports
The narrow-barred Spanish mackerel (Scomberomorus commerson) is wide ranging throughout the Indo-West Pacific region where it has been the subject of various age and growth studies. Methods used in these studies have varied considerably and in some cases may have led to misleading conclusions. The purpose of this report, therefore, is to document in detail the methods used in determining the age and growth during a FRDC funded stock assessment of the species in the waters off Western Australia. These methods are considered to optimise the collection, processing, accuracy of microincrement counts, and interpretation of the annuli in both whole …
