Pengembangan budidaya kerapu di Aceh

  1. 1. A Technical and Economic Evaluation of Grouper Nursing in Aceh, Indonesia Ujang Komarudin1, Michael A. Rimmer2, Islahuttamam1, Zaifuddin1, Samsul Bahrawi11: James Cook University, Australia; c/- BBAP Ujung Batee2: Balai Budidaya Air Payau Ujung Batee, Nanggroe Aceh Darussalam, Indonesia
  2. 2. Nanggroe Aceh Darussalam
  3. 3. Brackishwater aquaculture in NAD73,000 ha of coastal ponds (tambak)Originally constructed to farm shrimp  mostly P. monodonMilkfish Chanos chanos farmingGrouper nursing
  4. 4. Impacts of tsunami20,000 ha of tambaks damaged  another 5,000 ha out of production due to damaged water supply canals  9,000 ha totally destroyed271 of the 293 shrimp hatcheries in NAD damaged or destroyed (FAO data)Massive social dislocation due to deaths, damage to infrastructure
  5. 5. Slow post-tsunami recoveryPonds in use:  6% shrimp monoculture  25% shrimp / milkfish polycultureReasons for slow recovery 1. Prevalence of disease [mainly WSSV] 2. Higher feed prices 3. Lower output prices Options  Implementation of BMPs  Alternative commodities
  6. 6. Grouper aquaculture inIndonesiaHatchery production – BaliNursery rearing – Aceh, East JavaGrow-out – Batam, Lampung, Kepulauan Seribu, Sumbawa, ….
  7. 7. Grouper fingerling productionSmall-scale hatcheries  Buleleng Regency, Bali
  8. 8. Grouper aquaculture in IndonesiaNursing –Aceh Grow-out: Singapore Batam Lampung etc. Hatcheries – Bali
  9. 9. Study objectiveTo better understand the grouper nursing sub-sector in Aceh
  10. 10. SurveyBireuen  7 farmsAceh Utara  4 farms
  11. 11. PondsOriginally developed as shrimp ponds  500 – 8,000 m2
  12. 12. Phase 110–15 daysGreen kelambu (1 mm mesh)  2,000 pcs / cageFed mysid shrimp
  13. 13. Phase 220–30 daysBlack kelambu (4 mm mesh)  1,000 pcs / cageFed ‘trash’ fish
  14. 14. ManagementFed 2–3 times per dayGraded 3–4 daysHarvested after 30–50 days  >75 mm TL
  15. 15. SurvivalSurvival generally >75%Lower survival during wet seasonDisease problems  VNN  Ectoparasites
  16. 16. Business models1. ‘Middleman investment’  Most common model  Middleman provides operational costs: seed, feed, nets, etc.  Profit split 50:502. Farmer investment3. Farmer group investment
  17. 17. Profitability5,000 grouper will generate  IDR 2,375,000 – 5,000,000 (US $255 – 540) per cycle7–8 cycles p.a.Poverty threshold is IDR 2,288,228 (US $250) p.a. (World Bank data) IDR 20,000,000 Poverty IDR 10,000,000 Low IDR 0 High
  18. 18. BenefitsEconomic  Profitable business  Rapid returns (30–50 days)Social  Supports coastal aquaculture livelihoods  Social cohesion – farmer groupsEnvironmental  Uses mysid shrimp and fish (Gobiidae) from ponds  Low culture intensity – limited nutrient impacts
  19. 19. Sustainability issuesCapture of E. coioides juveniles from wildUse of ‘trash’ fish feed  Training in farm-made feeds
