my understanding in layman's terms is a diploid is a hatchery trout that will grow into an adult trout that has the ability to reproduce. A triploid trout though, has been sterilized, and therefore, because it never goes through the rigors of spawning, will grow larger and the quality of the meat stays good all year round.

Shortly after fertilization, eggs are exposed to increased pressure and temperature, which causes them to produce a fish with an extra set of chromosomes. There are then 3 sets of chromosomes rather than 2, hence triploid. A diploid fish is any normally developed fish, either from the hatchery, or natural, with only 2 sets of chromosomes.

and the interest for us angler (and also for fish farms) is that because they are sterile, triploids grow faster and bigger than diploid... They do not invest any energy in gonad production and keep growing bigger and bigger.

Sounds like they're messen' with nature again. Are triploids safe to eat????
We have been messing with nature ever since man started selective breeding for crops and livestock. We are nature, so I guess nature is messing with nature?? :peace:
