My green house for fish

What does your friend grow? I really like your approach of trying to use nature to reduce the work. How cool having all these fish and not being too tied down. How do you feed them during the week? I was reading on the Journey to Forever website about african aquaculture ponds have lights floated on them at night to attract the moths too the water and feed the fish, I want to try that, float and LED on a bit of polystyrene...

That's a great idea:naughty: I never though that.:wall:
That's why i like everyone participates in this thread. I'm always learning new things.

He grows saltwater fish for food. In english i believe it's Gilthead seabream (Sparus aurata)
and European seabass (Dicentrarchus labrax)

I don't feed them during the week.:WHOA:

That's unbelievable but it's true. During winter they are in a kind of a lethargic state. They don't eat much. In summer they eat alot but there are more insects (food) available. That's nature doing is work:popcorn:

If you don't have lots of fish you can do that.

Sometimes i ask my father, when i can't go there, and he feeds them.

I bought the drill pump. Here she is




It works. I don't know if it works properly at low rotations because my drill machine, the one i have here, only have one rotation. But i believe it works.

But i found some problems for the use i want. When i stop the drill machine all the water returns, go back. With a valve i think i can resolve this problem.

Other problem, and i don't know the answer yet, is the power that is needed to turn the axis of the pump. With the hands it's impossible to turn it.




I don't know if the wind power will be enough to turn the axis.

What do you think?

Not yet. Is Winter here. It's not to cold here in Portugla but not hot enough to have rays outside. In mid Spring it is possible to have them out. It's when i'm going to move them. Now the tank only have some Gambusia.

I think that if i do big blades i can have power enough to turn this pump. I must study this very well.

Wish list until the end of this Summer (what i'm planning to do):

- Close the new Green House with policarbonate (lots of €€€€);
- Finding/doing a system to oxigenate the water of the big tank (if possible wind powered). I believe the rays will be able to live in there without this system because there will be lots of plants, but i wan't to have a backup plan in case something goes wrong;
- Doing a system to help heating the water during Winter. I believe it's not going to be very dificult.

Lets see if i can make all this things until that time. I must win the lottery.

If you are building a windmill to generate elec the most important thing is speed of rotation, thats why wind turbines have few (2 or 3) blades with a small surface area, if you want a windmill to pump water the most important thing is torque or POWER!!!! For this you want lots of blades with a large surface area, have you seen the old wind mill pumps in the old western movies?
