Figure 1. Normal (N) razorback sucker larvae subjected to handling stress on a regular
basis through larval examinations developed severe principal caudal fin ray
deformities (D) immediately following the onset of ray formation. Diets included Fry

mixed with Spirulina Regular in a 9:1 ratio (HEG1+).
