Indonesia is known for its export of marine fish & invertebrates.
Since Indonesia has many islands and surrounded by the ocean it has a great potential to supply a large variety!
The farming of corals is now done at a professional scale.
During the last decennia the breeding of freshwater fish is gaining a large % of the export.
Not only wild fish such as Clown loach or shrimp but the breeding of uncommon fish, that are normally available as wild fish, is becoming important.
