"Massive Sardine Stranding Raises Concerns for Japanese Residents"

Thousands of tons of dead sardines have washed up on a beach in Hakodate, Japan, leaving residents puzzled. The cause of this phenomenon is unknown, but researchers speculate that the fish may have been chased by larger fish, exhausted due to a lack of oxygen, or suddenly entered cold waters during migration. The decomposing fish could potentially impact the marine environment by lowering oxygen levels, leading officials to caution against consuming them.
