Sidoarjo pond belt
Sidoarjo sits on the East Java coast behind a belt of brackish water ponds, called tambak, which have produced milkfish and shrimp for generations. What distinguishes it from other Indonesian aquaculture is proximity: the ponds, the processors and the port are within an hour of each other.
What makes it different.
- Traditional brackish ponds
- Tambak are shallow coastal ponds fed by tidal water, worked at lower density than intensive systems. It shapes the cost, the disease risk and the certification conversation.
- Milkfish and shrimp together
- Polyculture and rotation are normal here, so a processor's supply base is usually handling both species rather than specialising.
- Processing next door
- Surabaya and its surroundings hold substantial seafood processing capacity, which means short transport between harvest and freezing.
- An urban coastline
- This is an industrial and densely populated area, so water quality and traceability are questions to ask rather than to assume.
Getting it out.
- Tanjung Perak
- Surabaya's port, one of Indonesia's largest, with reefer capacity and frequent services. The distance from pond to container is short by Indonesian standards.
- Cold chain length
- Because harvest, processing and port are close together, the number of temperature handovers is lower here than for eastern Indonesian seafood.
What we source here.
Indonesian milkfish
Bandeng is farmed in brackish ponds and sold mostly deboned, because the bones are the whole problem. What that costs and what the paperwork looks like.
Indonesian vannamei shrimp
How farmed vannamei is counted, processed and shipped, and why the paperwork differs from wild-caught seafood: no catch certificate, but residues.
Indonesian black tiger shrimp
Penaeus monodon farmed in extensive traditional ponds. Why supply is uneven, and what the size premium actually buys.
Questions buyers ask.
Why does the pond belt matter to a buyer?
Because the length of the cold chain is decided by geography. Product harvested an hour from the freezer has fewer handovers than product moving from a remote island, and every handover is a place where temperature is lost.
Is traditional pond farming certifiable?
Some of it is, and traditional systems can meet aquaculture standards where the group is organised and records exist. It is worth asking to see the certification scope rather than assuming it covers the whole supply base.
Milkfish or shrimp from here?
Both, and they suit different buyers. Milkfish is a value product with a specific ethnic and regional demand, and shrimp is a global commodity with a much more demanding testing regime.
What does your service cost?
Five per cent of the order value, paid by you and never by the factory. A factory audit starts at $250 depending on location. We work with orders from $10,000 per shipment.
Buying from Sidoarjo and the East Java coast?
Tell us the specification and the port. We go to the region, look at the material and put the documents together before anyone quotes a price.
