I. Introduction
The Philippines is one of the world's leading fish producer. In 1995, it was 12th among the top 80 fish producing countries with a total production of 2.3 million metric tons, accounting for 2% of the world's 112.9 million metric ton fish catch. The following year, it was 13th among the 51 top fish producing countries with a total fish production of 1.8 million tons. In 2001, the country's fish yield further increased by 166,101 metric tons. There are different kinds of fishes and other aqua creatures like tilapia, tuna, mackerel, talilong, shrimps, seashells and most commonly the country’s national, the milkfish or bangus. Milkfish (Chanos chanos forskal) of bangus as locally comprises the bulk of aquaculture production in the Philippines. Its farming is regarded as the backbone of the Philippine aquaculture. They are hardy and fast growing, and can be raised in fresh and brackish water ponds, pens and cages. Being one of the dominant farmed-species for aquaculture, milkfish farming is geared towards high-density culture system, due to little or no prospect of expanding the brackish water farming area; support capture fisheries production which is on its continuing decline; and the rise and fall shrimps industry, due to disease problem. The industry’s remarkable progress can be attributed to the growing number of experienced shrimp farmers that are shifting to intensive milkfish culture. Various modifications in bangus culture have been developed towards attaining high bangus production. This manual aims to guide our fish farmers with systematized and modified milkfish farming practices. Milkfish production represents one of the main sectors of the nation's fishery industry .Fish culture is distinct from the marine and inland capture fisheries in that its research and development is like that of animal husbandry which requires a different
