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.
Spring and Fall are excellent times to stock trout in recreational ponds. However, stocking trout without knowing if they are appropriate can be disastrous. A fish kill can result either immediately or in the future without an understanding of specific pond and fish species characteristics. Rainbow trout are a preferred species by pond owners in Western North Carolina. However, some pond owners stock trout only to later discover the pond is not appropriate.
