Yes, most of the people that worked in the lab thought that way. I couldn't believe it! Of all people you would think they would know better, but no they just kept going with the blinkers on. :roll:

Thank you.

You can get DDSG (distillers solids) extremely cheap. Its mostly protein and a great fish food! If you make alcohol then you can make your own. Also see:

All you woodbe food makers a friend here in sunbury has just put a pellet machine in he makes chook dog food ect give me a recipie of over the counter stuff and i will run it by him and see what he can do]

To make pellets you need a binder of some kind. One person said eggs. I don't know what makes a good binder for pellets. Duckweek does not need a binder. I think freezer food is more reachable for most of us.

I.E.

Start with ANY greens, fruits and vegetables you can find. An example would include, but not be limited to; carrots, broccoli, yams, oranges, apples, Romaine lettuce, etc.
#

Put all the above in a blender or food processor.
#

Slowly add shrimp, crab legs (both with shells), and/or smelt. Do not use any fish that would contain high levels of oils, like herring or mackeral.
#

Blend mixture as fine as possible.
#

Add liquid vitamins or crushed tablets, you can also add Selco or Selcon. The mixture should have the consistancy of mud. Add some liquid to thin it up if it appears to thick, carrot or sweet potato juice works well for this purpose as it is high in vitamin content. You can also use clam juice or water.
#

Next: Boil 100-150ml of water and add the same amount of unflavored gelatin. Mix the gelatin and vegetable mixture together pour the resulting mixture into a rectangle pan and allow to cool. You can place the mixture in the freezer but be sure to score the mixture before it is completely hardened, to make it easier to separate later.
#

After the mixture is frozen you can separate the pieces and place them in freezer bags for use as needed.

I like the idea of non-meat sources of protein like duckweed, DDSG, and soy if theres no other option.

So brewers grains would work? As in from beer?

I was wondering, if you feed your fish veggie scraps, the fish poo which feeds the plants, and you harvest the plants to eat, are you reducing the nutrient in the cycle each time you harvest?

Tony From West Oz

Yes, Especially when you harvest the fish :O

While most of the growth comes from carbon from atmospheric CO2 and H from the H2O, the other elements in the system must come from somewhere.

You should add food from outside the otherwise closed system, as well as feeding the fish the plant prunings, veggie scraps and any fish bone/scale/skin/gut/head/flesh which is not eaten.

Additional external food will introduce trace elements to keep the system stable and ensure good crops. This food could be insects, fish food, or other food byproducts.

Hello,

I had two points to say about this topic

first in Europe it is written on the commercial fish food in pet stores that they are not for fish going to human consumption, don't know why but all the previous explanations must confirm this.

second, fish farming has been very intensively researched for the use of leftovers of biofuel processing and that is by all the big petrol companies, specially to do a new fish meal protocol:

=>start the fingerlings with high protein as fresh as possible (have a look at skretting gemma fingerling fish food) by not processing it with heat, I can tell by experience that this fish food is quite strange since your hands scratch and burn if you use it, this is to induce a high growth rate that will be kept during all the life of the fish

=>follow by the use of vegetable protein from biofuel scraps and synthetic omega 3 and 6, musn't forget to cure the fish every now and again just to keep the fat levels in the muscles low and tighten the flesh cells

=>end the growth period by a taste fish food with a supplement of insect meal, fish meal and a nice lipidic taste such as spirulina (only the lipids have taste, pure protein don't) do this for a month to cure the veggie taste out of the fish and fill them up with omegas, trace elements and minerals (they are inserting some trace elements like selenium to increase the sale price as selenium is supposedly good against cancer)

=>stop feedind for at least 48 hours and you have a nice fillet for a consummer that doesn't know anything about the food but the taste of it

That's the new protocol we will have at the place I work at and this will start by checking the contracts we have with our major clients to see if they have thought of this aspect of it, if not off we go!!

I might have to start looking for another job :wink:

Maybe someone knows of a nice aquaponic setup downunder that would need a new fish farmer or quality, food safety and environnement manager :lol:

You may want to look into "healthy choice" dog food. No preservatives and all the other crap that they can't use in "human" grade food. Might be worth a look.
