trout
This raising trout is a rather broad topic to begin with, guiding you in the right direction would take some doing, especially since you have not told us a thing about your intentions with them, i.e., what you intend on raising them in, how long you intend on maintaining them, etc.
As you must well know, trout (all trout species) grow rather large to say the least, with some species growing much larger than others. They are not aquarium fish, although you could temporarily raise a few up to what might be considered in most states as a “minimum keeping size,” in an extremely large tank, with a chiller. Best result would be had in a stream running through your property, although barring that possibility, a natural pond with water constantly flowing in and out of it from a fresh source (partial diversion of a stream) would work fine.
You also have not told us what kind (species) of trout you intend raising, unless you don’t yet know at this point. If not, this matter is not to be taken lightly, and I would first highly recommend your research this entire subject. Since you haven’t given us any information at all — even on the parameters of the water you will be working with — know that trout in general do not like warm water, even though some species may tolerate it briefly for a short time if clean and well oxygenated.
Brown Trout will tolerate the highest temperatures of all other trout, at around 75 o F (BRIEFLY), but do best below 70 o F. They actually PREFER water at between 54 o F and 66 o F, with a pH between 6.7 and 8.2.
Rainbow Trout prefer water of a pH between 6.8 and 7.8 (a slighly narrower range), and a temperate a bit lower than Browns. They will spawn around 55 o F - 58 o F, so that should tell you something — Fish only spawn within the optimum water conditions that they enjoy.
Brook trout are somewhat more tolerate as to the pH, with 6.5 to 8.5 being comfortable to them, and are more tolerant of slighly more acidic water. They do NEED colder water however, which should never go over 65 o F at any time — preferably kept best at around 50 o F, but will do alright somewhere under 60 o F, provided again that the water is well oxygenated (colder — and cleaner — water holds increasingly more oxygen as the temperature drops. All trout must have a minimum of at least 5.0 ppm dissolved oxygen in their water at all times at the very least, more whenever possible.
