Last week the beach at Kaka Point was littered with dead and dying paua after the heavy tide fell.
Residents in the area told the Otago Daily Times the ‘‘natural phenomenon’’ had occurred previously, but never as badly.
On Sunday, Dunedin resident Gary Allpress was walking his dog down Long Beach north of Dunedin, and came across ‘‘hundreds of those little bream-like fish’’.
Mr Allpress said he recognised the fish as he had seen similar things happen further north in the past.
Ministry for Primary Industries (MPI) regional manager fisheries compliance Garreth Jay said juvenile Ray’s bream fish were confirmed to have washed up along some beaches in the Dunedin area, including Whareakeake, Long Beach and Aramoana.
MPI officers had been on site at some of the beaches, and there was no evidence the dead bream were a result of fishing activity.
He believed recent weather and sea conditions had caused the fish to be pushed inshore and on to the beaches, and then to become stranded when the tide went out.
MPI has urged beachgoers not to gather or eat the dead fish or shellfish.
