In August 2008 the Noosa River Aust Bass spawned 2 million embryos and most developed with 2 heads and 2 hearts and died within 48 hours.
This year the Noosa River Sea mullet had severe deformities like the Noosa River Aust Bass with 2 and 3 heads then 2 and 3 tails. All the Noosa River Sea Mullet embryos died.
The travelling Noosa Mullet hatched but only a handful lasted a few weeks before dying. Without reproduction the river fish will all die out as no young ones will replace the adults.
Two-headed bass- Chemical toxins, engineering and risk assessment- an under-appreciated cause of fishery decline.
Spray drift of agrichemicals, and toxin discharges from STP’s will be discussed in light of findings of a veterinary investigations.
Matt is on the taskforce that is investigating the Fish Kill event and he will discuss the implications for inshore aquatic ecosystems.
