2. Quality biological material
• Quality brood fish – selection program ( a government job)?
• Quality eggs
• Quality juveniles
- disease free
- good growth
-big – 50 gram +

7. Yearclass separation - fallowing
• Keep only one yearclass on each site
• Fallow between each crop
• This is the best preventive action to minimize diseases

8. Indonesia – the offshore opportunity
• The environmental conditions in the ocean is exceptional good
• Wind
• Currents
• Temperature

9. Indonesia – the offshore opportunity
•# of sites to produce 100.000 tons:
•1992: ~200
•2012: ~30
•2020: <10?

12. What do you need?
Broodfish - cages and landbased
Hatchery – landbased
Nursery – landbased (tanks or ponds)
Ongrowing – cages offshore
Processing – landbased
Feed – landbased
Equipment - landbased

13. What do you need offshore?
• Platform (or barge)
• Moorings
• Workboat
• Cages
• Small boat for inspections

15. The Platform
• Platform of concrete or steel
• The platform will have
– 2 generators
– Feed silos or/and storage of feed bag
– Central feeding system
– Control room
– High quality accomodation with kitchen and showers
– Small fish disease lab
– Silage tank
– Fresh water tank

24. Day to day work on platform
• Feeding
• Mort removal
• Mooring and net inspection
• Washing of nets
• Health inspection

25. Cages
• Bigger is cheaper
• Bigger more difficult to handle
– Need better trained people

28. Human resources
• Well trained people important for success
• Well motivated people- well paid people
• 7 days on – 7 days off
• 5 -6 people per shift

29. Fish health
• Fish health specialists on shore
• Top quality people
• Top quality lab facilities
• Small lab on platform
• Prevention by high hygiene standard and vaccination
• Fish health the biggest challenge in aquaculture
• Daily removal of dead fish
• Silage of dead fish

30. How to get started?
• Start with:
– Small cages
– Concrete platforms with storage of bags and silo
– Feed by feeding gun or remote control from small boat
– Well boat for harvest and transport of feed or work boat for this
– Ensilage tank for dead fish on platform
