I've tried lolevel shut off switches and the shut down just for the fun of
it. Well the pacu are in the freezer. They were 3 inch fingerlings 90 day
ago. They weren't a uniform size and I don't have a scale but they where 5
to 6 and half inches long and from 1 to two pounds in weight. thats
impressive to me in 90 days.
Chris,
Two questions; did you have low level shut off
switches/alarms in place?
What species of Pacu are you raising? Can you discribe, and or compare the
taste/texture of Pacu in regards to other fish?
OOPS I think that was more than two questions.
Thanks, Bob

Pablo,
I would love to see your design. Since I am relatively new to this list, I
may not be able to make any improvement suggestions, but I would like to see
what you have designed and maybe ask some questions. I am a mechanical
engineer with 20 years of engineering design experience so I will probably
have some suggestions. However, be sure to take my suggestions "with several
grains of salt" since I am NOT experienced with aquaponics. My experience is
in telecommunications.

This is not meant to discouage any one. I get discouaged and
down for no reason at all but in the face of real setbacks I
laugh. I like these pacu and think they have great promise.

It's good to see you didn't lose your sense of humor along
with the pacu. Thanks for sharing this...we can all learn
from it.

About Tropical fish what do you want to know.? Where do you live and
what are your local water conditions?. Often the biggest thing to get
right in your head about tropicals is that its childs play to raise
tropicals if you raise the one's that need the water conditions( hard
water or soft water) that you all ready have and than concentrate on
them so you have few problems after that its just water changes and
feeding out to sale size. Aquaponics systems like mine or Mark's or the
S-S system used as a grow out just make it easier

We have used plastic mesh sheets on all inlets and outlets with good
results. Critical pumps get two or three layers of diminishing sive size.
larger pumps get stainless steel mesh screen. We have a submersible chopper
pump in the lines from the greenhouses. It will pump; small rocks, mud,
plant debris and some bones from livestock buildings.

Stainless is the way to go if you have it inside the tank
But if you can blow heat around with a fan all that you really need
is to blow hotter air up against the outsides of your system especially
the bottom and your water circulation will take care off the rest Your
water temps are going to be around 5 degrees Fahrenheit cooler then your
air temps no matter what you do any how so heating the room is a valid
way to go and I have used it for years.I tend to get rid of over
engineered bells and whistles regularly

OOPS I think that was more than two answers
Chris Jeppesen
My question for the group is this.
Since the weather has changed the pacu were not there selves. They didn't eat like they did
when it was hot and they tended to preydate the gold fish. When my total nitrates were hi I
know this was a factor but but for 4 weeks before the kill I had eight 4x8 grow beds on 1 800
gallon tank with 150 lbs of fish in it. (thats the back ground) But with the cool weather my
water temp would swing from 78 deg f. in the late afternoon to 68 deg f in the early am. . jWas
this temp swing my problem. The pacu ate much better above 72-73 deg f.
Any thoughts>

I may have to go that way if I can't watch the details of haveing the pump flat on the concrete
in the bottom of the sump. I was just careless. I'm useing a wayne 1/4 hp sump pump and it
pumps peagravel leaves and stems regularly. the stinking little mouse was just a little to big
for the intake.

Oh you asked about what I grow at the moment in fresh water Tilapia
, catfish and various African cichlids and tropicals all in the same
system in the 2 south well light facing fish rooms of my home(this due
to the river often flooding out my basement) with banks of rain
gutters/ square and round 4in.X4in.X 6ft pipe running across the
windows on 24 inch lateral drilled to except pots with more run across
the other walls over the tanks as plant beds .These pipes/gutters also
double as breeding raceways for some of the fish .Next year if I buy
this place ill remove the roofs of these rooms and replace them with
glass.
And I am building a Coral farm of about 1000gals. such as you see
at the Garf. web site in another room

Teresa the window of low cost small pacu fry availability for the year
is about over but maybe not .Most have grown to a more expensive size
call your wholesaler via the pet store and see. They can order anything
for you NOTE: cultivate a friendship with the store owner and save big
bucks!

Chris You answered your own question when Pacu conditions are dialed in
they are voracious feeders but like most warm water fish they go off of
feed when they cool down and in cooler conditions they need more protein
and switch so the gold fish were handy. They are impressive growers and
Intelligent fish don't you think?

How about this - what tropical fish would be easiest to raise in:
rain water,
temps as high as 95 in summer,
as cold as 40 in winter,
herbivores,
live with low oxygen,
mmmhhh...live with children and a total beginner in aquaponics?

Id like to know if anyone has developed a market for the pacu. I mean
is it a popular fish in your nick of the woods. Is it easy to sell. What
sort of prices do you get for them in comparison to tilapia. Or do you
end up stocking your and your neighbours freezers.
