Palm Beach fish deaths still a mys­tery

Southern Telegraph - - NEWS -

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”.
