Seafood CRC: retail transformation - identifying opportunities for creating consumer focused Australian salmon value added products

Project number: 2008-794.10
Project Status:
Completed

Need

There is a need to:

1. Develop low value Australian seafood options in order to give the Australian seafood consumer the chance to purchase local seafood at accessible price points.

2. Evaluate the sensory characteristsics, product acceptability and perception of Australian Salmon from a consumer perspective. The attributes evaluated will include, but not be limited to, taste, texture, appearance, mouth feel portion size, etc. This information should relate to pricing and potential product forms that appeal to consumers. This will demonstrate if the species has the potential to be a sustainable, consumer commercial fishery. There is currently no consumer research information of this type available.

3. Show what attributes consumers value in seafood.

4. Understand the composition profiling, nutritional values and bio chemical factors that:

a) influence the spoiling of desirable characteristics;
b) influence the overall degradation of this particular species

This will fill gaps in the current research that is being undertaken.

Objectives

1. Identify at least 3 concepts for a range of potential new retail added value Australian Salmon products (ChemCentre)
2. Develop a consumer model for the evaluation of product acceptability and perception (Curtin University).
3. Improve understanding of the nutritional and bio chemical profile of Australian salmon as the basis for product and process development (ChemCentre)
4. Report of consumer attributes of Australian Salmon and its current positioning (Curtin University).
5. Provision of a comprehensive final report on potential of retail transformation for the Australian salmon industry (ChemCentre)

Summary

Australian Salmon represents one of the last sustainable, relatively untapped wild catch fisheries in Australia with capture and harvest techniques not having changed significantly for many decades. Fish quality is quite variable and harvest practices are not optimised. As a result, consumer confidence in Australian Salmon product has been adversely affected. Harvest practice and immediate post-catch handling can be significantly improved, and are major determinants of product quality.

Current and existing research lacks fundamental, basic information on consumer perceptions and acceptance of the Australian Salmon. This project aimed to fill a critical knowledge gap in existing and concurrent research projects.

Australian salmon (Arripis trutta): Population structure, reproduction, diet and composition of commercial and recreational catches in NSW

Completed

Need

The eastern Australian salmon stock appears to have increased substantially in recent times and is believed to be under-utilized. Despite this, management of this species in NSW has been contentious, and is restricted by a lack of knowledge on biology and population dynamics. Specifically, managers require information that will assist their decision making concerning: (i) the status of the stock; (ii) potential expansion of the commercial fishery; (iii) impacts of resource allocation, and; (iv) ecosystem effects of salmon population expansion.

There is a lack of information on the sizes and ages of salmon being harvested and little knowledge of their biology. Research on age and growth in the 1970’s was based on scales, which have since been shown to be inaccurate (Egglestone 1975). Studies on reproduction have been limited to the timing of spawning in the southern regions. Results from this project will provide the necessary information on the composition of landings, age, growth, reproduction, movements and diet to enable informed management of the salmon resource. This project aims to address issues directly related to NSW management, however the baseline information will be valuable for management across the range of the stock.

The project outcomes of improved knowledge and management of salmon will directly address the FRDC R&D program “Natural Resources Sustainability” and the strategic challenge to “Improve the sustainability of natural resources supporting wild-catch and aquaculture”. At the state level, this project will satisfy three priority areas of research listed under the key document “Planning strategic research, aquaculture and aquatic conservation in New South Wales, 2004-2009.” These are: (i) to examine the predatory impacts of Australian salmon on other commercially important fish species; (ii) information on age and growth of recreationally important species, and; (iii) development of stock assessments for target species in the ocean hauling fishery.

Objectives

1. Determine whether eastern Australian salmon comprise a single stock along SE Australia
2. Describe the catch composition of eastern Australian salmon taken by commercial and recreational fishers in NSW, including spatial patterns in sizes and ages
3. Describe the reproductive biology of eastern Australian salmon in NSW, including their size/age at maturity and where and when they spawn
4. Model growth (using otolith derived estimates of size-at-age) of eastern Australian Salmon
5. Develop yield per recruit and spawner-biomass per recruit models at present levels of fishing mortality
6. Analyse existing tagging data for patterns of movement and potential stock delineation
7. Describe diet and potential localised impacts on prey items
8. Describe the totemic and cultural significance of Australian salmon to the Aboriginal people of NSW

Links between seagrass habitats, piscivorous fishes and their fish prey

This project has increased our understanding of the importance of seagrass habitats to larger, commercially valuable, species of fish by combining experimental and correlative scientific principles. We found that many small fish use seagrass habitats for nutrition and to avoid predation by large...
