The most convenient and practical system for eel culture in the Philippines is the use of an earthen pond or fishpond. The size of the fishpond depends on the intesity of the culture method. In our country the culture of eel is not as popular as the culture of other food fish like the tilapia, milkfish and other freshwater and brackishwater species fish species. Very seldom you will see a fish farmer or entrepreneur use eel as the culture commodity species.
In scientific term "Glass Eel" of "Elver" are the terms use in small eel as in fingerlings for other fish species. Elvers as they are commonly called can be bought to where they can be found mostly in Cagayan River in Northern Luzon Region 2 and Buayan River in General Santos City in Southern Mindanao. The price depend on the availability of the elvers and is very expensive.
In Taiwan eel ponds range from 800 sq m-2,000 sq m with a water depth of 1-1.5 m, while in other countries the range is about 3,000 sq m-10,000 sq m with a water depth of 50-70 cm. Eel fry 0.2 grams can be grown to 20 grams in one year because of its slow growth rate. Young eels to marketable size of about 150-200 grams are grown for another one year.
The type of feeds given during the culture period affect their weight. Eel fry are fed mainly with worms and fine pieces of cooked trash fish. Synthetic and/or commercial feeds are use for eel grow-out culture. Other feeds use for eel culture includes small crabs and other crustaceans unsuitable for human consumption, offal from slaughter houses, aquatic worms, and silkworm pupae. The feed (except worms and pupae) is chopped into small pieces.
Mortality are caused by bacterial, fungal, protozoan and metazoan diseases which can be avoided by proper sanitation of the culture ponds and water being used. The capital requirement is very high due to the long period of the culture of about one and a half year to two years (1.5-2).
The eel species that are common to Cagayan River and Buayan River are the marbled eel or giant mottled eel , Anguilla marmorata, A. luzonensis and Indian short-finned eel, A. bicolor pacifica . The latter species prefer to stay in estuaties while the other two mentioned earlier prefer freshwater environment.
