ABSTRACT This study describes the prevalence of a parasitic bopyrid isopod, Parapenaeon consolidatum, on Metapenaeopsis dalei and its effect on host growth and reproduction. The prevalence of P. consolidatum increased with shrimp size, from 27.3% at 5 mm CL to 68.4% at 16 mm CL. Lengths of female bopyrids and that of their hosts were positively correlated. This indicated that the bopyrid stays continuously with its host and is not detached when the host molts. Morphometric analyses indicated that parasitized male and female shrimp have slightly lower body weight and length than nonparasitized shrimp of the same carapace length. The gonadosomatic index was higher for ...
