Palm Beach fish deaths still a mystery
Results from tests following last week’s fish kill at Palm Beach have not found anything unusual that could be a cause of the event that resulted in about 1000 scaly mackerel washing ashore.
The small tropical sardines were discovered washed ashore or floating in shallow water along Palm Beach up to the Cruising Yacht Club early last Wednesday morning.
No other fish species were believed to be affected.
Analysis of a water sample taken by Fisheries officers from the Department of Primary Industries and Regional Development indicated low levels of phytoplankton, which is unlikely to have caused the kill.
Additional testing will be carried out to try and determine the cause of the scaly mackerel mortalities.
The department also received reports on Friday of starfish mortalities on Challenger Beach further up the coast at Kwinana.
Fisheries officers who attended reported up to 100 dead starfish washed on the beach, from which samples were collected for analysis.
hey also attended Woodman Point in response to multiple public reports of erratic fish behaviour, described as “pilchard- type fish leaping out of the water”.
