Number of Aquafarm |
| Definition |
Aquafarm refers to a farming facility used in the culture or propagation of aquatic species like fish, crustaceans, mollusks, and aquatic plants. It includes fishpond, fish pen, fish cage, fish tank, hatchery or “pangitlugan”, seaweed farm, oyster farm, mussel farm and other farms for culturing of pearl, cockles, and abalone. |
| Indicator 2 |
Type of Aquafarm |
| Definition |
1. Fishpond refers to a body of water (artificial or natural) where fish and other aquatic products are cultured, raised or cultivated under controlled conditions. This is a land-based type of aquafarm.
Examples of species usually cultured in fishponds are milkfish (bangus), tilapia, hito (catfish), carp, siganid (samaral), sea bass (apahap), prawn (sugpo), shrimp (hipon), and crab (alimango).
2. Fish pen refers to a fish enclosure made of closely-woven bamboo screens, nylon screens or nets or other materials attached to poles staked at the bottom up to the surface of the lake, river or other shallow bodies of water for the purpose of growing and/or culturing of fish to various sizes in fresh, brackish and marine waters. A fish pen varies in shapes. Its enclosure covers the entire water depth from the water surface down to the bottom.
Note that fish corral (baklad) which is used for trapping fish in tidal waters or along the natural paths of fish is not considered fish pen. Both have similar features and materials used. The only difference is that a fish pen is a fish enclosure where fish from outside the enclosure cannot enter while a fish corral is constructed with openings to serve as fish trap.
Examples of species cultured in fish pens are milkfish (bangus), carp, tilapia and sea bass (apahap).
3. Fish cage refers to a stationary or floating fish enclosure made of synthetic net wire/bamboo screen or other materials set in the form of inverted mosquito net (hapa type) with or without cover with all sides either tied to poles staked to the bottom of the water or with anchored floats for aquaculture purposes.
A fish cage is suitable in the culture of fish species that burrow into the lake bottom because it limits the fish inside the confines of the cage.
Examples of species cultured in fish cages are milkfish (bangus), tilapia, carp, grouper (lapu-lapu), siganid (samaral), and sea bass (apahap).
4. Seaweed farm refers to a farm for cultivating seaweeds in suitable water areas by any method with appropriate intensive care for production in commercial quantities.
The culture of seaweeds may be carried out by tying them to stones, straw lines, nets and other instruments which are set in a manner that is elevated from the sea bottom to protect them from predators in the sea.
Examples of varieties of seaweeds which can be cultured are eucheuma (gozo), gracilaria (gulaman dagat), and caulerpa (lato).
Gathering of seaweeds is not classified under aquaculture but in the gathering of aquatic products under fishing operation.
5. Oyster farm refers to a farm for cultivating oysters in suitable water areas by any method with appropriate intensive care for production purposes.
6. Mussel farm refers to a farm for cultivating mussels in suitable water areas by any method with appropriate intensive care for production purposes.
7. Fish tank is a land-based structure made of wood, glass, metal or cement, usually rectangular or cylindrical in shape designed to grow and culture fish for breeding and seed fish production. It may be constructed below or above the ground level and capable of holding and interchanging water.
8. Hatchery or “pangitlugan” is an aquafarm where brood stock eggs are hatched and reared into fry in a body of water (artificial or natural) contained in tanks or ponds under controlled condition in fresh or saltwater environment.
9. Others (SPECIFY) includes aquafarms which cannot be classified in the aforementioned types of aquafarms. Examples are farms for culturing pearl, cockles, and abalone.

Size of Aquafarm |
| Definition |
The size of aquafarm was based on the area of the aquafarm. Grouped into nine (9) size class, the lowest size group was “Under 0.500 hectares”. The highest size group was chosen as “25.000 hectares and over” instead of breaking it further into several smaller size groups in as much as the farms falling under these sizes more fewer in number.

| Indicator 4 |
Water Environment
|
| Definition |
The type of water environment used in the aquafarm is any of the following:
1. Freshwater refers to water environment without salt or marine origin. It is pure freshwater, that is, no mixture of seawater, such as Laguna de Bay, Taal Lake, Candaba Swamps, Liguasan Marsh, and rivers, canals, dams, paddy and rice fields, lakes, ponds, and springs.
2. Brackish water refers to mixed seawater and fresh water environment with salinity of less than 30 parts per thousand (ppt) that varies with the tide. Examples are tidal flats, mangroves, swamps, and mouths of rivers, where seawater meets the fresh water.
3. Marine water refers to seawater environment with a salinity ranging from 30 to 40 ppt consisting of ocean, bay, gulf and channels. It is pure saltwater, such as Manila Bay, West Philippine Sea, and Albay Gulf.
