If my maths is correct (mostly it isn’t!) then 0.15mm can be expressed as 150 microns.
There are sets of artemia sieves that you can buy. The set that I have has the brand name “Hobby” and consists of four sieves (5 x 5cm) of 900, 560, 300 and 180 micron mesh. I think JBL offer similar sets – though I don’t know their mesh gauges.
I also have a 53 micron sieve bought from here. If you scroll down the page you’ll come to it ; and you’ll also see a 125 micron sieve. Alternatively, you can buy the mesh separately and make your own sieves!
There surely must be an equivalent source in your country : the keywords to use for a search are the appropriate translations of ‘mesh’ and ‘micron’.
If not, then I’m sure ZM Systems will send overseas.
