Abstract

The authors have assembled a unified body of information on milkfish (Chanos chanos) aquaculture in the Philippines to pin-point where further efficiencies of resource use in the milkfish system can be obtained. Each of the subsystems-procurement, transformation, and delivery-is examined in turn.

The major inefficiencies in the Philippine milkfish resource system occur in the transformation sub-system rather than in the fry procurement or delivery sub-systems. Reduction in mortality rates during rearing and increased application of supplementary inputs such as fertilizers are the two major means by which the existing system can substantially increase the supply of milkfish available to consumers in the Philippines.
