After the fires burnt down the shed that I had my aerators in I had to replace it quickly so I purchased a forty foot high cube shipping container to house the aerators and it works well, but the aeration room at the end of the shipping only take up a small area the rest of the container will be used for aquariums that will house river blackfish and some pygmy perch so people who visit will get to see a blackfish.
The first photo shows the first six foot aquarium with a blackfish ( in the pipe) and some perch.
The photo below shows the room with the aerators one for each pond , they are small and the reason for that is blackfish dislike a lot of current in the water especially around mating time so these aerator provide air and some ciculation of the water but not to much. I have used garden hoses that have a pressure rating for air hoses they are stronger I have buried them under a track and they work fine,
As you can see from this photo below the diffuser is attached on top a blue drum which is about nine hundred cm high they are weighted with steel and placed in the middle of the pond, the reason for this is so as not to stir up the silt on the bottom of the ponds, blackfish like clear clean water as much as possible.
We are now heading into breeding season, plancton will start to form when the temps rise a bit just in time to feed the young fish that we hope will be there this year.
Blackfish this time of year go quiet and don’t eat much ,if you force them to feed you can kill them , the food sits in their guts and goes off because their metabolism is so slow, this fish has been separated from the herd so I can show visitors a fish he has a six foot aquarium all to him self apart from a hand full of pygmy perch to keep him company .
This fish would be around four years old and should be old enough to breed, I have had quite a few people who come to the farm to see the fish and the set up I have created to breed these fish.
While fisheries have told me they will try and breed these fish it could as much as five years away before they start so wouldn’t hold your breath waiting for them.
If you are a youngster just starting out on a life time of fishing, remember fresh live bait is always preferred by fish , if you cant get fresh and alive then get the next best thing, remember to that it sometimes takes effort to find your fresh bait whether its worms or yabbies or in this case wood grubs.
These grubs are found in trees often at the end of their lives and you can often see holes on the outside of the tree where some of the grubs have already left, the grubs have a flat head unlike the Bardi grub which is more rounded and of course they are found in holes in the ground under some Gum trees .
No matter the kind of fish you are after fresh is best .
Travis Dowling from fisheries has assured me that the hatchery at Snobs Creek are to attempt to breed River Blackfish along with other troubled fish such as Trout Cod, this is good news maybe at long last the Blackfish will get the recognition they deserve.
This does not mean that I have given up on a southern hatchery I am just please there are finally experts who put their knowledge to the problems surrounding this fish, I wish them well.
Its way past time that we got serious about saving this fish as you can see its been going on for to long.
1919 blackfish study
UPDATE: I went back to the Cooriemungle creek after heavy rain today and found the creek flooded, if I was standing there right now I would be under water .
This is the bridge where I recorded the video below , this water is bound for the southern ocean where it serves no purpose , you would think it would be better kept in the river to support blackfish and platypus , but due to heavy erosion from past clearing of the Heystbury forest it is so silted up that most of this water will not be there in a few short months.
below is some pictures of the clearing of the land in the catchment of this creek , I know this because i was on a farm cleared in the 1960 and saw this first hand.
We did this to the creek with bulldozers and stump jump ploughs , so we can fix it and I dont know why something hasn’t been done to date.
If people are serious about saving native animals such as the blackfish and platypus then here is a golden opportunity to do just that , having endless rounds of meetings and sending text to each other will do nothing to fix the situation.
I visited the Cooriemungle creek recently and found not much has changed , this creek once held blackfish and platypus but not anymore.
I have repeatedly asked the overseers of these rivers and creeks for action and none has been forthcoming .
