Numerical and structural variations in the giant nuclei of Neoechinorhynchus cylindratus collected from Micropterus salmoides and Esox lucius in Silver Lake (Kenosha County), Wisconsin, were systematically studied. The number of nuclei (usually 17 in males and 9 in females) in the population examined was correlated with host species, season, sex and developmental stage. Structural changes observed in all giant subcuticular, lemniscal (in both sexes) and cement gland, nuclei (in males) corresponded with initiation, continuation and termination of reproductive activity of worms. Both morphological and positional changes of the nuclei in each of 5 developmental stages are described.
