Officials in Japan have admitted they are struggling to determine why hundreds of tonnes of fish have washed ashore in recent days.日本官员表示，他们正在努力确定最近几天数百吨鱼被冲上岸的原因。

日本海岸一周内两次出现大量死鱼

这是继12月7日北海道出现大量死鱼后，日本海岸一周内第二次出现该情况。

Earlier this month, an estimated 1,200 tonnes of sardines and mackerel were found floating on the surface of the sea off the fishing port of Hakodate in Hokkaido, forming a silver blanket stretching for more than a kilometer.本月早些时候，在北海道函馆渔港附近的海面上发现了约1200吨沙丁鱼和鲭鱼，这些鱼形成了一条长达一公里多的"银色长毯"。

On Wednesday, officials in Nakiri, a town on the Pacific coast hundreds of miles south of Hokkaido, were confronted with 30 to 40 tonnes of Japanese scaled sardines, or sappa, which had been observed in the area a couple of days earlier.12月13日，在北海道以南数百英里的太平洋沿岸，波切渔港的官员又发现了30至40吨寿南小沙丁鱼，几天前就曾在该地区发现这种鱼。

报道称，渔港内部分死鱼已经腐烂，开始散发出恶臭，当地政府已投入挖掘机等重型机械回收死鱼。

Local fishers scrambled to collect the fish, fearing their carcasses would lower the oxygen content of the water as they decompose and damage the marine environment.由于担心死鱼会腐烂破坏海洋环境，降低水中氧气含量，当地渔民们争相打捞这些鱼。

离奇死鱼引渔民担忧 

当地渔民表示，第一次见这么多死鱼漂浮在海面上，并担忧短期内频繁出现大量死鱼可能意味着海洋生态系统正在发生变化。

“I’ve never seen anything like this before,” a fisher who has worked in the area for 25 years told the Mainichi Shimbun. “It was only around last year that we began to catch sappa in Nakiri. It makes me wonder if the marine ecosystem is changing.”一位在该地区工作了25年的渔民告诉日本每日新闻社，“我以前从未见过这样的事情。直到去年左右，我们才开始在波切捕到寿南小沙丁鱼。这让我怀疑海洋生态系统是否正在发生变化。”
