What yield and FCR does trout give and how do I manage fish health?

Trout grows well in cold, well oxygenated flowing water and can give a good yield per raceway, but the production depends heavily on water temperature, flow and stocking, so the range is wide and warm spells reduce growth. The feed conversion ratio with good trout pellets is usually reasonable, but the high protein feed is costly, so feed efficiency strongly affects profit. For health, the main protection is steady cold clean water, correct stocking that the flow can support, good quality feed and not overfeeding, since most trout problems trace back to warm water, low oxygen or fouled water. Do not use random medicines for sick fish. Contact your state Fisheries department or trout hatchery officer for diagnosis and advice. Treat yield and FCR figures as ranges to verify locally.
