In this day and age of environmental awareness, it's just sad that this sort of thing is happening. Especially to our coastline - which is so supposedly well protected.

To think the Government have the nerve to point to recreational fishing as pressuring the ecology of our waters. 

Thats not good, i'm not familiar with the area but I haven't seen fish kills like this in 'open' water before. The link between elevated nutrient levels and de-oxygenated water (as i understand it) is because the nutrients cause algal blooms which decompose, then bacteria feeding on it use up the oxygen. And then there are toxic algae and such. In a more open system like this you'd think the fish could simply swim away. Is there lots of algae around? You say this has happened for the last four years, I assume u mean coinciding with heavy rainfall (winter)?

 I wonder if the dredging has something to do with it as it's not like it has only rained for the last week.

hope someone gets to the bottom of it, greenies, pew???

did that sign with the orange fencing attached say anything related to this?

 Not good to see you would think they would have done somthing by now. What kinda fish where down there man.

We have councils quick to stop fishermen/women fishing here there and all in between because people will fish the place out, yet we have the same group of people quite happy to allow the same tragic environmental set of circumstances to persist in killing large amounts of fish.
Never mind sitting in your office pondering is the world flat or round what about getting out "there" and doing something to improve the environment.
Rant over

100% agree with megladon, rec fishos get shut out of places and blamed for anything that goes wrong, but somehow they allow water that has excessive levels of nutrients to be pumped into our water bodies. The govt says they care for the environment, honestly I don't think many of them give a dam, if they turn a blind eye to events such as this. It happens almost every year in the swan as well with our bream.

Here in Karratha we had an advertising blitz about not fertilising your gardens to "Save the blue swimmer crab"

Seemed a bit pointless as we dont get rain up here.  Did you have the adverts down there, did anyone pay attention to them?

Hahaha Chinese restaurants now have specials on all dishes that include fish!!!! Rockingham stores only

I didn't/haven't seen any adds to that effect although that type of thing should be run in the Peel area. The poor old Murray and Serpentine estuary systems suffer some thing chronic from fertilizer run off and we are starting to see more and more outbreaks of green algae blooms.

 Here's a crazy idea - pretty crazy but still an idea....

 Maybe if everyone stopped putting petrochemical fertilizers and toxic herbicides, etc on their lawns and farms the resulting runoff might not kill all the fish.....    just a crazy idea....

no-one or no law to enforce it, and farmers are untouchable.

 what species of fish died? look like blowies to me, so no great loss

 Bugger where's petermac when you need him??
