Aquaponics - Silver perch feast

I cant remember if I even mentioned this because I was probably in some kind of deranged pain killer broken rib induced state when it happened, but I may have forgotten to mention I ate one of my big silver perch.

It looked like this.

The South Australian Fisheries people suggest the most humane way (and best way to protect it's eating qualities) to dispatch a fish is to plunge it into an ice water slurry, and leave it there.

A few hours later I scaled and cleaned it, and lightly salted it inside and out.




I wrapped it in whatever you call thin plastic kitchen wrap where you live, and left it in the fridge for twelve hours, then cooked it whole.

It was one of the nicest fish I have ever eaten.

Crazy fat.

You cant really tell from this angle, but it was in very fat condition. Looking down from the top, it had that thick section just before it's tail like a dolphin.

Most wild caught fish don't seem to have that.

I'm guessing it's because life is a little tougher in the wild when you don't have an unlimited amount of feed available.

Anyway...

This fish was in very good condition and had excellent fat content.

Apparently silver perch fat is high in Omega 3, but it was mostly delicious.

It weighed 1.08kg gutted and scaled and was 33 cm long.

I wish I had built a much bigger system ages ago so I could have a lot more.

Successfully farming your own protein in only a couple of cubic meters or space is an amazing thing to be able to do in suburbia.

I totally recommend it.

Entomology - Maggot harvest

My maggot self harvester works.

Which is nice.

I found a stack of lines radiating out from the collector on the table.

I'm guessing that means its been working pretty well for the last 12 hours or so.

Working well, except for the "not letting them get away" bit. So I can enjoy a few extra flies over the coming days.

I think it's safe to assume we all knew that was going to happen.

The ramp even worked, although it has to be said that this particular maggot is actually using it to go back down.

It must have changed it's mind.









But eventually it seems, the little beasties find their way to the exit, and drop down into the container of   horrible tasting breakfast cereal that I gave them.

I dusted the wall of the orange collection container with flour, and that seems to have stopped them escaping, but who knows.

What this does mean is that I can make a better device that's sealed where it should be, and make some  fish food out of stuff that would otherwise go to landfill.

The stink factor was essentially zero, so no problems what-so-ever about doing it in a suburban back yard. From more than six inches away, there was no detectable smell at all. Basically you had to put your nose to it, and we had some very hot, dry days, some hot humid days, and half way through I added a stack of water, so it wasn't stink free because it was dry. (I added water because the dead fish was starting to turn into a dried fish, and wanted to keep it fly friendly)

And they were big and healthy looking.

This one, just big.

It's one of the escaped ones that was foolish enough to escape my cereal feed lot. I watched it being kissed by a black house spider, as it stumbled into it's web.

The upshot of this was a very obedient maggot who was happy to stand still on a ruler for as log as it took to get a nice photo of it's length.

Thanks nature.


The perfect house warming present for a fishing buddy, has got to be a lifetime supply of fresh maggots, via a lovingly hand crafted, self harvesting, suburban suitable, stink free, maggot growing, fish head recycling, bait farm. And I have just such a fishing buddy, who recently relocated to a place where you cant buy maggots for bait, and he just bought a boat.
