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.
Table 24: Summary capital and operating costs
| Option | Capital cost, K | Operating cost, K |
| 1a) Basic quarantine station plus occasional use of existing facilities (eg Aiyura, Gana) plus one or more simple ancillary sites | 80,000 | 25,000 |
| 1b) As above but purpose-built quarantine unit | 130,000 | 35,000 |
| 2a) As (1a), plus upgrading of coldwater facilities and additional ancillary sites | 140,000 | 105,000 |
| 2b) As (2a), but developing new site rather than upgrading existing site. | 280,000 | 120,000 |
| 3a) As (2a) plus upgrading of Aiyura system | 240,000 | 150,000* |
| 3b) As (2a) but developing new site rather than upgrading Aiyura | 440,000 | 200,000 |
| 4a) As (3a) plus simple recycle system/ storage facilities, basic lab, Wewak or Madang | 260,000 | 170,000* |
| 4b) As (4a) but more completely developed, with hatching facilities, increased brood-stock capacity, at Wewak or Madang | 380,000 | 200,000* |
| 5a) System with new coldwater site (2b), plus fully developed system in Madang or Wewak (4b), plus ancillary sites | 520,000 | 250,000 |
| 5b) As (5a) plus new zone II site | 720,000 | 300,000 |
| 5c) As (5b) plus fully developed system in both Madang and Wewak | 850,000+ | 330,000 |
* 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:
establishing the basic quarantine facilities; eg under separate project initiatives such as EEC or bilateral agreements, or under national quarantine responsibilities;
upgrading coldwater facilities; eg under separate project intiatives, or national or provincial programmes;
upgrading Aiyura; eg under separate project initiatives or national programmes;
installing local hatching facilities; eg as part of community development projects;
the project may more usefully focus on the development of the zone III facilities, and on the provision of technical and management inputs to the other parts of the project. However these priorities could only be finalised once external initiatives were more clearly defined.
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:
ascertain potential development plans for existing sites; Kanudi, Gana, Mendi, Aiyura, and check site availability at Madang and/or Wewak;
define operational/support links with Fisheries Dept, Animal Health Dept, etc; identify staff responsibilities and additional staff requirements;
confirm priorities for introduction with Advisory Group/ Government authorities; identify target sources of material, times of availability, etc;
confirm outline plans, budgets, equipment lists, etc, based on likely level of support from associated agencies;
outline possibilities and likely timing for alternative project funds/developments; possibly prepare background case material to support requests for assistance;
if new centres likely, as soon as feasible make suitable arrangements for contract procedures, and preparation of plans as required;
organise initial staffing groups and co-operating staff;
set up quarantine centre; allow at least 3 to 6 months; test operation with inter-basin transfers;
if possible, start direct transfers to cool water areas, eg with instream hatching systems;
bring in initially cleared imported stock;
start to introduce and ongrow potential broodstock in place; liaise with existing staff - eg Gana, Aiyura, during its operation/development to start some stocking activities;
start longer-term developments;
bring in other stock;
