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.
Rainbow Trout Stocking. Each winter from December through early March, Texas Parks and Wildlife Department stocks rainbow trout in more than 100 locations across Texas. The hatchery-reared trout are 9 to 12 inches long and create a put-and-take fishery: we expect that most will be caught within a few weeks after being stocked. In spring and summer, most Texas waters are too warm to provide suitable habitat for rainbow trout. Trout stocking has been completed for the 2016-2017 season.
