Enhancement of saucer scallops (Amusium balloti) in Queensland and Western Australia - genetic considerations
Establishment of Seafood Services Australia stage 1 - extension and advisory services
Demand for assistance from clients in areas such as live transport, modified atmosphere packaging, value adding, market information, etc continues. Requests for information in three new areas have increased. These are:
(i) A search for alternative export markets and domestic outlets for product formerly sent to Asia. In order to assist in this area, Alan Snow has recently competed an export facilitation course through the Australian Institute of Export.
(ii) A need to comply with food safety regulations and quality assurance specifications of customers and ultimately ANZFA. This is expected to increase as a result of the SeaQual initiatives.
(iii) A requirement to support the SeaQual Chooser initiative through supply of suitable material for the SeaQual packs and through an increased volume of requests for customised information packages resulting from the distribution of 35,000 Choosers.
More specifically, industry needs from AUSEAS that we have identified are:
1. Assistance to people who are exploring new ventures, products, and processes. This includes value adding and processing options, market details, and technical information.
2. Information on contacts in markets, government agencies, and other service providers (eg consultants, freight forwarders, equipment providers). AUSEAS needs to maintain a comprehensive list of contacts and to keep information on the capabilities of providers of services to improve coordination across the seafood industry.
3. Customised assistance to companies implementing food safety plans and quality management programs in cooperation with SeaQual initiatives.
4. Trouble shooting when problems occur, usually in the form of telephone advice or short targeted written material.
5. Advice on funding assistance, usually in the areas of product and process development applications to NSC. This can include reviewing applications before and after submission and assessment of reports.
6. Demand for brief targeted information to be provided free of charge through delivery methods such as internet, fax-back, etc.
7 A centralised delivery point for information on seafood related matters acting as a "one stop shop" for the industry.
8 A need to promote the national post-harvest infrastructure services of FRDC. i.e. AUSEAS, NSC, and SeaQual.
Final report
This report covers the activities projects 1996/341 and 1999/333 for the period 1996 to 2000. In October 1999 AUSEAS along with the National Seafood Centre (NSC) and SeaQual were brought together under the umbrella name of Seafood Services Australia (SSA).
To avoid confusion, for the remainder of this report, the previous name of the service AUSEAS (Australian Seafood Extension and Advisory Service) has been replaced with the new title SSA.
The report begins with a review of current activities including:
- industry inquiries and the SSA responses;
- consultancies;
- the preparation of the Australian Seafood Industry Directory;
- the sales of technical literature packages.
A discussion of the available information resources is then followed by promotional activities. This is followed by a consideration of staffing issues including staff skills development to better service clients’ needs.
Finally, there is a discussion of planned new initiatives including development of a “one-stop shop” Internet site for the post-harvest fisheries sector. This will allow clients to access a wide range of information held in the SSA databases including: the bibliography of the technical information available through this service; sources of assistance for industry development; and a topical issues discussion line. A special feature of this will be a series of technical advisory notes.

A study of the sand crab (Portunus pelagicus) and its exploitation in a sub-tropical multi-sector fishery
Final report
Based on logbook records the sand crab commercial pot fishery in Moreton Bay is worth in the vicinity of $2 million wholesale annually. Sand crabs are also taken as an incidental by-catch by otter trawlers and in addition Moreton Bay supports a substantial recreational fishery.
Sand crabs are caught throughout the year but fishing effort is greatest from October to June. Peak catches in the pot fishery occur during March and April when daily catch rates may exceed 3 legal males per pot. Gravid females are present throughout the year but the highest proportion of egg bearing females is found in the population during August and September. Peaks in mating activity occur in autumn and spring with recruitment of juvenile crabs commencing in November. The parasitic barnacle Sacculina granifera infects 3% of all sand crabs in Moreton Bay and a previously unreported microsporidian parasite is found in 0.7% of the population.
Tagging studies show that fishing effort and mortality of sand crabs is highly variable throughout the Bay. Recapture rates for different areas vary from 1% to 65% with an overall return rate of 14%. The pattern of tag returns does not indicate any ordered directional movement of crabs either into or out of the Bay.
Male and female sand crabs exhibit differences in preferred habitat. Large males are generally more abundant in deeper water, whereas females predominate in shallower water, particularly on the top of sand banks.
Management recommendations arising from the project work include a change in the method of sand crab measurement to the width at the base of the antero-lateral spines, lowering of the existing size limit, the introduction of a bag 1 limit for recreational fishermen and an abolition of the prohibition on taking females provided that suitable management conditions can be maintained.
