Eel Culture |

The consumption of freshwater eels,
primarily Anguilla japonica, in China, Japan, Korea and other parts
of Asia represent a volume of almost 300,000 tons annually. The industry
relies heavily in the catches of baby glass eels and elvers as they migrate
inland from the sea into the rivers and streams where they spend their adult
life. They then migrate back to the Pacific Ocean to breed, thousands of
feet below the sea. The baby eels are then carried by the Kurushio current
to the Sea of Japan, then into the rivers and streams of Japan, China and
Korea. The high demand and seasonal availability of Anguilla japonica
has driven prices to exorbitant levels. To satisfy eel demand, eel aquaculturists
worldwide have been growing other species, such as Anguilla anguilla
in Europe and Anguilla rostrata in North America. Because of over
harvesting, the export of Anguilla anguilla outside of Europe is
increasingly being restricted. 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:
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. Elvers. Eels in their transparent, post-larval stage.
