Development of the egg production method to assess the blue grenadier stock in the South East Fishery

The blue grenadier stock is potentially the largest fish stock in the SEF, and following the decline in quota of orange roughy, the need to assess its potential became urgent. The stock has been surveyed using traditional trawl methods and acoustics, but both methods provide only 'snapshot'...

Development of acoustic methods to survey orange roughy in the eastern and southern zones

Three acoustic surveys were carried out between 17 and 20 July 1996 on the orange roughy spawning ground off St. Helens, Tasmania. A combination of 22 demersal trawls and ensonification with three frequencies (12, 38 and 120 kHz) was used to assess the species composition around the spawning hill....

The impact of changes in fishing patterns on red-legged banana prawns (Penaeus indicus) in the Joseph Bonaparte Gulf

The fishery for red-legged banana prawns in the Joseph Bonaparte Gulf (JBG) developed in the early 1980s. Since then, fishing effort has varied from 700 to 2600 boat-days per year and catches range from 200 to 1000 tonnes per year. Initially the JBG fishery developed as an alternative to fishing in...

Estimation of population parameters for Australian prawn fisheries

One of the main objectives of fisheries management is to ensure the sustainability of fished stocks. To reach this objective scientists have to adequately assess the status of fished populations with quantitative models of the fishery systems. Most of these models require estimates of population...

Indices of recruitment and effective spawning for tiger prawns stocks in the Northern Prawn Fishery

In the mid to late 1980s NORMAC began to suspect that tiger prawn spawning stocks in the NPF may have been reduced by fishing to levels that reduced recruitment to the fishery. A vessel buy-back scheme and other effort reductions were introduced to reverse this trend but, by the mid-1990s, the...

Resolution of taxonomic problems and preparation of a user-friendly identification guide to whole fish and fillets for South East Fishery "quota species"

An upgraded identification guide to fish and fillets of the South East Fishery (SEF) quota species groups has been compiled from new information. This reference, South East Fishery.Quota Species: an Identification Guide (Daley et al., 1997) and hereafter referred to as SEF Species Guide, was...

Need

(The needs addressed in the original Handbook application remain current [Appendix 1]).

Despite the exceptional diversity of Australian seafood, there is no relevant, comprehensive identification guide to assist Industry personnel or consumers. This fact was highlighted recently in a FRDC-funded market survey of the excellent 1994 Australian Seafood Catering Manual (Kane et al, 1994, hereafter referred to as ‘The Catering Manual’). This report assessed the success and usefulness of The Catering Manual, which included the names of over 175 domestic seafood species and photographs of 54 but virtually no information on how to distinguish them. Remarkably, 63% of Catering Manual users surveyed use it to identify species (QDPI, 1997). This book has pictures of less than 12% of domestic seafood species and only very infrequent notes on how to identify them but is used by a majority of Industry personnel as an identification guide. There is an obvious need for a thorough and comprehensive identification guide.

FRDC recognised the need for such a guide and in 1994 funded the “Handbook of Australian Seafood”. However, during the Handbook’s production, the following issues have been raised:

• The original Handbook grant application allowed for the inclusion of 60 imported and 240 domestic species. However, we have now identified 466 domestic species, an increase of over 90%. (Imported species are addressed below). The inclusion of these additional species is critical to the Handbook’s success; a comprehensive guide would instil greater confidence in, and awareness of, the range of products available and would help promote less fashionable seafoods.

• A repeatable, objective method of identifying the flesh of species by protein fingerprinting has been used in the production of the Handbook to date. Such a technique is required when fish substitution is suspected and the inclusion of protein fingerprints in the recently published South East Fishery Quota Species—an Identification Guide (CSIRO, 1997, hereafter referred to as ‘The SEF Guide’) has been welcomed by, among others, the Australian Government Solicitor’s office (Appendix 2). It is important that this technique be applied to all species included in the Handbook, including the additional ones discussed above.

• Marketing Names for Fish and Seafood in Australia, an authoritative guide to correct marketing names for Australian seafood, was published in 1995. However, Handbook-related research has identified problems with domestic species included in the book (imported species are addressed below). A number of common commercial species are not included and some, worthy of unique marketing names, are currently placed in ‘catch-all’ groups (e.g., Lutjanus russelli, marketed widely as Moses Perch, is currently included under Sea Perch, Lutjanus species).

• While examining fillets to collect data on distinguishing features, we discovered numerous useful characters that, to our knowledge, have not been documented for identification purposes anywhere else. The comprehensive inclusion of this data in the fillet identification section of the Handbook would provide a unique and valuable resource for the post-harvest sector of the Industry and to consumers, and would set the standard for such work worldwide.

• Preliminary research into frozen seafood species imported into Australia has shown the need for a thorough investigation of its composition. The Marketing Names Guide included about 50 imported species. We recently surveyed eight importers who, between them, import only 14 (28%) of those but who also import 30 or so additional species. We propose to review the composition of Australia's seafood imports and summarise our findings in a second Handbook dedicated to imported species.

Objectives

1. To produce the definitive handbook to all fresh and frozen seafood species, including both domestic and imported fishes, marketed in Australia
2. To include within the handbook the means of identifying flesh and fillets of these species based on their genetic fingerprints
3. To include wihtin the handbood other information of value to the marketers not covered in or by other industry references
4. To structure the guide so that it becomes the basic reference to consumers as well as marketng sectors of industry
5. Produce the definitive handbook for the identification of all fresh and frozen domestic seafood species marketed in Australia.
6. To review the composition of Australia's seafood imports and produce a handbook for the identification of contemporary imported seafood species.
7. To include with both handbook volumes a means of identifying flesh and fillets of these species based on their protein fingerprints.
8. To include with both handbook volumes other information of value to marketers (including oil composition information, FRDC project 95/122, in handbook volume 1) not covered in or by other industry references.
9. To structure the handbook volumes so they become basic references to both consumers and marketing sectors of industry.
