1. Provide a review of relevant literature.

2. Engage key players in the supply chain (feed manufacturers, farmers, processors and retailers) to gain an understanding of their options and the practical constraints on using substituted diets.

3. Provide a comprehensive, independent assessment of UK consumer attitudes towards the use of non-marine, vegetable based feed substitutes.

4. Based on the results of objectives 1-3, identify the barriers to the use of non-marine feed substitutes.

5. Make recommendations with respect to overcoming the constraints to the use of non-marine based feed substitutes.


Phase 1.

1. A desktop review of literature on: fish health, welfare and production characteristics when fed on substituted diets; environmental impacts of substituted diets in terms of sourcing and feeding; product quality for consumers when using substituted diets/"finishing" protocols; use and sourcing of substituted diets in other producer countries; presence in the UK marketplace of those products from other countries. The review will take account of the full spectrum of published and grey literature, including feed sector research, where this can be obtained. The focus will be on key papers and documents.

2. Structured discussions and interviews will be undertaken with key players in the supply chain including feed manufacturers, farmers, processors, retailers and relevant NGO's, to obtain their views and policies on substituted diets and their feeding requirements for Atlantic salmon.

3. The outcomes of 1. and 2. above will be assimilated in a Phase 1 report.

Phase 2.

1. The Phase 1 report will be used to develop a survey designed to identify consumer attitudes towards the use of substituted feed in farmed fish. The survey will be run by Ipsos MORI who will provide guidance on the design of questions.

2. Detailed analysis of the results of the survey will be conducted. The review and survey results will be used to identify constraints and possible solutions to resistance to the substitution of marine sourced feed components.

3. Provide a detailed report and presentation to the project Sponsors
