Introduction
Eel is the common name for any fish of the 10 families constituting the Order Anguilliformes, it is characterized by a long snakelike body covered with minute scales embedded in the skin. Eels lack the hind parts of fins, adapting them for wriggling in the mud and through the crevices of reefs and rocky stones. According to Schrank in year 1798, freshwater eels are catadromous, that spawn in tropical ocean waters, and have a peculiar leptocephalus larval stage that is unique to elopomorph fish. They constitute a single Genus, Anguilla.
The fishing for freshwater eels, along with environmental pollution and other human impacts, have all contributed to a significant decline in eel numbers over the last 25–30 years. Total volume of glass eels collected on an annual basis is around 150 tonnes which satisfies the current aquaculture needs of approximately 100 tonnes/year with the excess going to human consumption in Spain. Many people are involved in the eel collection, transportation and distribution, from glass eel fishers to the eel farmer and processor (Nielsen, T.; Prouzet, P. 2008.)
Freshwater eels can also found on the menu in many countries, the major market for Eel is limited to Japan and a small number of European countries including Italy, Germany and The Netherlands were they are considered a delicacy. The market value of eels depends on the species and varies between different countries. Currently prices range from 3-15 US$/kg which rank the eel among the most precious species of food fish.( Herwaarden 2003). In the Philippines, freshwater eels have different populations
