Backyard Aquaponics
A place to discuss aquaponics

Mark they eat most things but only small quantities, except for Gambusia, and acording to Jim and Adrian from MTI both have used canned shrimps, but at $2.00 per 200gms it's a tad expensive

Have you tried feeding them by the moon cycle?
I'm sure C1 could help.

Fed 'em a few of the larger, female, gambusia this morning - all gone in the blink of an eye !

if you had a tank with some tilapia you would be able to produce lots more live feed than you could with gambusia I think?

Running red fin maybe a bit debatable in WA. Running Tilapia especially south of Perth is probably lock him up and throw away the key time.

Grunta we put 30 Gam's in a soak less than a year ago and now literally millions, I doubt anything will out breed Gam's, someone down here has tried Tilapia without huge success, the water I think is too cold

Tilapia in this erea are a dead loss unless you are prepaired to heat your water and I mean heat it.I made a mistake with the heater nob and turned it way up .At 38 c they thought it was just lovely .

Hope all that requested got copies of the paper I got from NZ, I haven't managed to read much of it, need some time off (maybe I should change profession and become a teacher ) but have not much success with much feed wise other than worms, will go and get some Gambusia and give them a treat this weekend, maybe when trout go in they may follow them to the pellets

I'd be feeding Gambusia to the trout ! Once they're big enough.

don't know the protein level of a gambusia, never eaten one, but have eaten a trout pellet and there okay

Crazy Narroginites

Narroginite I just had to correct you spelling.

Only 1, ok then

Then you need to read that paper I gave you a copy of about the growth rates of barra fed gambusia vs barra fed on pellets !!

Protein: 59% (vs 45% in pellets)

Also, they have about the same fat % and only half the carbs of pellets. This gives them a much better protein:energy (P/E) ratio, which is a good thing and explains the better growth rate.

a reddie carked it yesterday and was severely chewed on the back end, it was a much smaller one than the others and I surely think they are cannibals despite what I have read, BSF loved him anyway
