question:

Can anyone give recommendation regarding how to control larval mycosis (Lagenidium and Sirolpidium diseases)?

In order to control larval mycosis, you can use a weedkiller which will
act as a fungi-static. This means it will not eradicate your mycosis
but it will block spore development.
One which is commonly used is Treflan.

Treflan works ok for Lagenidium as a preventive (I think 0.5 ppm is the recommended dose) although not when the disease has already spread, in that case you can use chlorine (>200ppm).

Last season, we had this in one spawning room. This room remained constantly humid and moist, unable to dryout properly and water getting under the fibreglass floor of the spawning tanks.

As soon as we moved away from spawning in this room, the problem stopped. If you have movable spawning tanks, try sun drying them. Look at general hygiene, especially airstones and airlines (clean and sterilise daily).
