We evaluated two existing prawn hatchery facilities for conversion to marine fish culture.
•
Both hatcheries were easily adapted with minimal cost and modification.
•
The Australian design was the simplest and cheapest to convert with a theoretical fingerling output of 630,000 × 40 mm (1 g) per batch.
•
The Taiwanese design required more work due to the built-in nature of the concrete tanks with a fingerling output of 320,000 × 40 mm (1 g) per batch.
•
Use of these facilities would resolve the current poor availability and high cost of juveniles for grow-out.
