Culture of Eels
Angulas is a Spanish delicacy comprised of baby eels cooked in olive oil and herbs. The delicacy is expensive in Europe and soon also subject to harvesting constraints because of environmental concerns. Poseidon has developed the ability to culture Pacific eels to the correct size needed to meet the demands of this growing specialty gourmet industry.
Poseidon’s interest in eel culture dates back several years, its research and development program primarily directed towards developing the four alternative eel species found in Southeast Asian waters. The successful breeding of these eels relies on identification of the appropriate species to culture that matches the taste and meat characteristics of Anguilla japonica, the selection of the right species at the elver stage and the satisfaction of feed requirements needed to culture eels of commercial size and value.
The following are Poseidon’s proprietary technology and business developments in the culture of Southeast Asian eels:
• COLLECTION OF GLASS EELS. The company has identified locations where eels emerge from the deep sea and has organized the collection and live transport of glass eels from these various rivers and tributaries to its testing facilities.
• SORTING OPERATION. Because the glass eels come in from the sea as mixed species, a sorting operation has been developed that efficiently segregates the local species A. japonica, A. celebensis, A. bicolor and A marmorata. This separation allows farmers to grow only those species that have commercial value.
• CULTURE OF ELVERS. The critical period in eel culture is the period from glass eels to juveniles. Mortality occurs from a variety of factors and slow growth or stunting occur in a large proportion of the eel population. Poseidon has developed appropriate culture methods to take the eels from the glass eel stages to juvenile sizes with less percentage of loss, making these eel species more economically viable through commercial culture.
Culture to commercial sizes, feed technologies and processing technologies are well known. Similar methods used for A. japonica and A. anguilla may be effectively used for the other species as well.
