Does anyone know offhand the number of pin bones in each of the common
salmonids -- Atlantic, chinook, coho, chum, pink, rainbow trout/steelhead? Is
it a fixed number per species/genus? How is the number related to the number
of ribs? I am also assuming that the number of pin bones is fixed by the time
the fish reach adult shape, and that they grow in size but not in number as
the fish grows. If anyone has this information at their fingertips, or can
refer me to where to look it up, I'd appreciate the help.
