Abstract
Lacistorhynchus tenius (Cestoda: Trypanorhyncha) eggs were not viable at 8.5 and 17.0 ppt salinity seawater, and coracidia and procercoids tolerated 25.0 and 34.0 ppt. High temperature (19C) shortened coracidia hatching times and survivorship, increased sizes of procercoids, and decreased prevalence of infection in the copepod Tigriopus californicus. Low and high (4.3 and 28.0) intensity infections of L. tenuis induced mortality. As the intensities increased, the mean individual area (size) of procercoids decreased, suggesting a crowding effect.This publication has 2 references indexed in Scilit:
