The tsunami fish was an individual of the bill bars chart Oplegnathus fasciatus that in the partially submerged hull of the Japanese boat Sai-shou-maru survived after the boat in itself Tōhoku earthquake in 2011 had broken loose and was driven off. On March 22, 2013, the boat washed up on the coast at Long Beach , Washington , more than 6,400 km (4,000 miles) from the point of departure. The fish then lived in the Seaside Aquarium in Seaside , Oregon .

Tsunami and route

The Tōhoku earthquake of March 11, 2011 was the most powerful Japanese earthquake recorded to date. The resulting tsunami drove the 6.1 m (20 foot) long Sai-shou-maru from Iwate Prefecture out to sea. The boat may have been flooded with seawater containing marine life, including the larvae of striped cochlea, by then. While the wreck was drifting across the Pacific Ocean for two years , the larvae grew into fry. Scientists disagree on whether the fish were actually washed into the hull of the ghost ship by the waves off the Japanese coast or near Hawaii .

discovery

The wreck of the boat was discovered as flotsam on March 22, 2013 , with a compartment in the rear part of the boat forming an 'aquarium'. The small ecosystem contained five sea bass as well as 30 other species of plants and invertebrates . Four beakfish were euthanized by the Washington Department of Fish and Wildlife shortly after their discovery, perhaps because there were concerns that the warm-water fish could develop into a neozoon . Researchers at Oregon State University examined on the basis of these copies the actual age and the diet of the fish. The fifth fish was brought to the town hall in a bucket. Shortly afterwards, the Seaside Aquarium confirmed on request that it would take care of the fish. The tsunami fish was exhibited in the aquarium at least until the end of 2013.
