High temps linked to fish deaths

Pilbara News - - News - Tom Zaun­mayr

High wa­ter tem­per­a­tures and low oxy­gen lev­els are likely to have con­trib­uted to mass fish deaths near Wick­ham over Christ­mas, ac­cord­ing to the Depart­ment of Fish­eries.

Video sur­faced on Face­book in De­cem­ber of thou­sands of dead bait­fish washed up near Wick­ham Dog Beach, spark­ing an in­ves­ti­ga­tion by Fish­eries.

Fish­eries north­ern re­gion man­ager Peter God­frey said the large school of bait­fish had likely be­come trapped in a tidal catch­ment at low tide, which would have rapidly lost suf­fi­cient oxy­gen be­cause of the num­ber of fish there.

“Test­ing of sam­ples col­lected on the day the fish-kill re­port was re­ceived in­di­cated that dis­ease was not a causal fac­tor in this case,” he said.

Mr God­frey said any fish kills should be re­ported to FISHWATCH on 1800 815 507.
