Challenges in Japanese Eel Production

July 16, 2015 — Today the Japanese consume around 100,000 tons, or 70 – 80 per cent of the worldwide eel catch, but in 2013 the Japanese Ministry of the Environment designated the fish as a species at risk of extinction, and in June 2014 it was placed on the International Union for Conservation of Nature (IUCN)’s Red List of Threatened Species.

In Japan, aquaculture is extremely important to the eel industry’s success, with most eel caught in the wild as juveniles and then raised on fish farms. However, the overfishing of juvenile glass eels has now become a huge problem.

Fed on a diet of fishmeal and kept in fossil-fuel-heated greenhouses, eel are usually collected along the Pacific Coast between December and April and put into tanks where their chances of survival are improved thanks to heating apparatus that helps increase water temperature particularly during the winter, and a circulating filter system in which water is filtered and re-circulated.

Ponds or specialized tanks are then used to grow the eels in temperatures of around 23oC – 28oC, after which regular grading takes place in which the eels are separated according to size and harvested once they are large enough to have reached market value.

Japanese fisherman preparing to reunite with his boat in B.C., four years after tsunami

July 3, 2015 — After the earthquake, a 23-metre-high tsunami ripped through the Japanese port town of Ofunato, destroying houses, tumbling cars like toy blocks and capsizing ships in the harbour. Stacks of freight containers were swept off the docks and sent hurtling through the town. People fled up the steep streets around the harbour, and the air was filled with the terrifying screeches of buildings being torn apart.

This was how the great earthquake and tsunami of March 11, 2011, arrived in Ofunato, a town of 41,000 that, through the miraculous journey of one small boat, has become linked to the tiny fishing village of Klemtu, population 450, on British Columbia’s Central Coast.

When the wave of water that rose along coastal Japan that day swept back out to sea, it left more than 15,000 people dead and took almost five million tonnes of debris with it. Lost were about 1,000 vessels, including many of the boats in Ofunato harbour. Most of the debris soon sank, but an estimated 1.4 million tonnes drifted offshore.

Four years later, fragments of the communities shattered in Japan continue to reach North America’s West Coast, raising pollution concerns but also serving as touching reminders of what was lost. Everything from small plastic toy soldiers that washed up on beaches to a 50-metre fishing boat that eventually sank in the Gulf of Alaska has made the crossing. Most of the debris can’t be traced, but occasionally serial numbers allow a connection to be made.
