Is it possible to transport a large amount of eggs from a spawn safely?
Any experience on this?
Would it work if transported in bags with water+oxygen+zeolyte, inside of well insulated boxes? ... assuming water parmeters are similar in both tanks (source and destination)

Running at last... Not bad, but is obvious that it could work better if: 1- better screen (the original!!) 2- bigger box (horizontally) to allow longer screen hence easier water flow through the screen 3- the floating dam should slip more gently, although if the water level is more or less constant ...

The floating dam in place.
Underneath the bowed screen a submersible pump (4000 liter/hour) is pumping the water to a 470 liters (1 meter width, 60 cm high) round filter with moving K1 (the black type)

Here you have what is expected to behave like a proper floating dam

I'll try using a stainless steel mesh 250 microns, this won't allow easily the water coming through. Therefore I set up two additional plastic mesh on top of it, so the water can break and go through more easily (last pic). In the 2nd pic you will notice the gap between the two plastic mesh and the ...

The structure is made of plywood, fiberglassed. It has two water inlets of 5 cm diameter (for pipes coming from the bottom drain and midwater)

3000 liters tank in the terraced roof, 5th floor of the building

However none of the existing sieve filters was adequate due to their size, the tank is around 40 cm deep. W...
