Backyard Aquaponics
A place to discuss aquaponics

Many bugs handle being frozen easily.

makes a bigger case for cooking first eh

Yeah, I did Daneil... I think I added too much spinach and Spirulina powder too. But with my vultures, suckers and the yabbies it cleans up in no time. I am making a PDF document about my experiment. I filled up around 15 zip lock sandwich bags, flattened then frozen so I can break it up easy.

wow, 15 bags, my batch only filled 4 but i flattened them too...
look forward to seeing the pdf though

Went to the supermarket to find some beef heart. All the had was diced lamb heart.

Is this close enough guys?

I chopped it REAL small, the silver fingerlings liked it, and the catfish warmed to it eventually.

Tella ya what, i looked at my tank via a tiny LEDlight in the dark, the cat fish are DEFINATLY a nocturnal creature! they even followed the light

Hi,

My partner makes dog treats for our two Maltese Terrors. They consist of liver, wheat germ, polenta, chopped parsley and all manner of good things which are then baked to form a crusty biscuit slice which is then cut up into small cubes. Our dogs find them highly addictive.

Over the weekend, I tried feeding some of the crumbled up mixture to my fish. While they ate some they weren't as keen as the dogs and it made the water stink like cooked liver for hours afterwards.

I've tried feeding chopped chicken heart and they really go for that.

My suggestion would be to feed the chopped heart out fresh.....or even to spread it out on waxed paper and freeze it before bagging it up.....to form what the food industry refers to as IQF....Individually Quick Frozen.

After my most recent experience, I'm more convinced than ever that they answer is not to cook up a mixture of ingredients but rather to feed the ingredients out cafeteria style......chopped heart, sprouted grain or seeds followed by a free choice duckweed salad.

When i bought my beef heart i went into the supermarket before the butcher, and was on alot of the printed price tags on the packages it said things like "minced beef heart" "lamb heart", etc i was abit suprised at how much "heart products" there were until i looked at the rest of the package and it said something like "minced beef, ideal for stirfrys, heart fondation approved". I was thinking the prices were expensive for heart, DOH!

anyways, i might try plain chopped heart, etc
It sounds alot easier than doing all the mincing, mixing, etc
(the only reason i made my fish food was for ornamentals..i dont trust aquarium fish flakes for fish destined to eat)

LOL, wasn't going to say anything, but i too found many "hearts" before i realised. Funny how when you're looking for steak all you read is "steak" when you're looking for heart all you read is "heart"

Found this info on pumpkin seeds. They seem to have a lot of minerals and protien. Could these some how be incorperated into a feed or directly into the system to boost missing elements? Here is the site..

just on seeds, it has been mentioned before, but prouting them is a good idea. when the water hits the seed they enzymes start to activate and do alot of protient type conversions............meant to be better as a whole

One little germ of an idea perhaps.

Example .. warm up some type of seed such a mustard seed, dessicated coconut. Put it in a caulking gun. Extract the oil, use the oil to power your diesel engine ... no messy biodiesel conversions, just mix the oil with 10 % diesel.

Feed the spent oilseed residue from the caulking gun to the fishies as part of a balanced and varied diet.

i gotta try this caulking gun thinggy J7..............oh, and i haven't forgotten about your DVD, (well, i HAD, but i've remembered now )

Hi,



If you're planning to do this, borrow someone else's diesel engine....or try an old stationary engine......particularly if your's is a modern common rail diesel......they require fuel of a very high standard.

or make friends with somebody who works for RACQ

Use real good filtration of the fuel!

Heat the fuel a little.

Older engines work best , something like a lister / petter ...

In fact the wear on the injectors and pumps is better than that of using pure diesel. (I had Listers confirm my wear measurements after 1000 hours of use.)

I have a friend running a bus around the USA on a veggie oil / diesel mix.

However, I think this subject has been touched on before on this forum... and I don't want to go off track.

Maybe we can discuss on another off topic thread?
