Abstract
Small pieces (10-15 mm long) of D. dendriticum plerocercoids were injected into rainbow trout (Salmo gairdnieri). The scolex, anterior region and posterior region of the plerocercoids were removed prior to injection. The small pieces of D. dendriticum developed [in 2 yr] into very long, slender plerocercoid pieces (152-310 mm long when killed and fixed in formol saline) without regenerating a scolex, developing segmentation or primordia. Growth and differentiation is apparently controlled from the scolex, or neck region, and if this is removed, uncontrolled growth and abnormal development may occur.This publication has 2 references indexed in Scilit:
