Identifying The Developmental Stages Of Preserved Eggs Of Snapper, Pagrus Auratus, From Shark Bay, Western Australia, Jeffrey V. Norriss, Gary Jackson

Fisheries Research Reports

The characteristics used to identify 19 developmental stages of preserved eggs of snapper, Pagrus auratus, collected from Shark Bay, Western Australia, during annual plankton surveys, are described and illustrated. A key is provided to enable the age of each egg stage to be estimated based on sea surface temperature and salinity observed during sampling. This report is intended as a reference for inexperienced staff, to ensure that between-year comparisons of snapper spawning biomass, estimated using the daily egg production method, are based on consistent egg staging and ageing methods.

Interim Management Arrangements For The Commercial Mackerel Fishery. Ministers Responses To The Final Report Of The Mackerel Independent Advisory Panel. (Fisheries Management Paper 164), Kim Chance

Fisheries Management Papers

The Government recognises that the mackerel fishery is important to both the recreational and commercial fishing sectors. However, the purpose of these arrangements is not to allocate the mackerel resource between the sectors but within the commercial sector. Resources sharing issues are subject to investigation in the Integrated Fisheries Management Review where alternative management frameworks and principles for allocating fish stocks to ensure maximum benefit to the community are examined.

Report To The Minister For Agriculture, Forestry And Fisheries By The Integrated Fisheries Management Review Committee, Department Of Fisheries

Fisheries Management Papers

The Integrated Fisheries Management Review Committee was established to develop a strategy to integrate the management and sustainable use of fish resources. The Committee’s report proposes an alternative management framework and a set of guiding principles for allocating fish stocks to ensure optimal benefits are realised for the WA community. The report does not, and was not intended to, address specific allocation issues in particular fisheries – this will be a function of the framework and processes put in place following this review.

Fisheries Research Report No. 132 - A Review Of Food Availability, Sea Water Characteristics And Bivalve Growth Performance At Coastal Culture Sites In Temperate And Warm Temperate Regions Of The World, Sidney A. Saxby

Fisheries Research Reports

The suitability of a coastal area for bivalve farming, as well as the density at which bivalves can be farmed in that area, is limited by the available food supply and other environmental variables. In this review, a range of successful and marginal bivalve growing areas in temperate and warm temperate coastal areas around the world are characterised. These include areas of high food and nutrient levels, such as Saldanha Bay in South Africa, and the Seto Inland Sea, Japan, through to more oligotrophic areas, typified by parts of the South Australian coastline and the Mediterranean Sea. The latter areas …

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries Management Papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …

Fisheries Research Report No. 133 - Preliminary Assessment And Seasonal Fluctuations In The Fish Biota Inhabiting The Concentrator Ponds Of Dampier Salt, Port Hedland, With Options For The Potential Application Of Results, Brett Molony, Gareth Parry

Fisheries Research Reports

The concentrator ponds (CPs) of Dampier Salt, Port Hedland, cover an area in excess of 7 300 ha. Water is pumped from two adjacent, mangrove-lined estuaries at certain times of the year and small and larvae fishes are carried into the ponds, becoming trapped. A survey of the fish biota within the CPs was undertaken at four time periods between May 2000 and February 2001 to identify the species of fishes present and to estimate their abundances and distribution throughout the CPs. Further, the Artemia resources within the CPs were also assessed for identification of species and quality.
