6.1 Summary of options

At the minimal level, the project will require basic quarantine facilities, together with a simple network of holding/production/ distribution facilities. Of these, facilities for zone I and to some extent zone II would have the most immediate priority for developing subsistence food resources in the river system, though for longer-term development, zone III facilities would be needed relatively early, to allow sufficient time for quarantine, reproduction, distribution, and build-up of stocks. In outline terms, the costs of the various options and levels of development are summarised in Table 24, based on the earlier tables. The most practical and cost-effective options are underlined. Note: operation costs do not include direct costs of bought-in stock.

* allowing for some savings through shared staff, etc.

In practice, assuming availability of sites, and depending on final species priorities and allocation of budgets, a gradual development from option 1a to 2a, towards 3a then 4a, and later possibly to 4b, would appear to offer the best and most cost-effective approach.

As far as the present project is concerned, an immediate priority would be the quarantine unit, closely followed by the setting up of some arrangement for zone I and II species. However, as there is at least a possibility that funds for some parts of the development could be obtained elsewhere, eg for:

6.2 Suggested implementation

The actual implementation of this phase of the project would depend greatly on the factors discussed in the previous section. However, a number of specific priorities can be identified:
