When food enters the small intestine, bile travels through the common bile duct to reach the duodenum. Gallstones are hard deposits that form inside the gallbladder when there is too much bilirubin or cholesterol in the bile.
That said, there is a considerable consensus that all three major trout species (brook, brown and rainbow) begin to experience some level of stress at around 68Â°F (20Â°C), with that stress increasing rapidly as the temperature rises further.
Cycle: During October and November the Brown's will move into their homes streams and tributaries to Spawn. Ideal conditions for spawning are: a gravely bottom at the head of a stream, with a temperature range of 44Â° -48Â° F. Food: As a young trout, the Brown feeds mainly on aquatic insects. Once they reach maturity their diet turns towards medium minnows and chubs occasionally feasting on large crayfish and even rodents.
