Sorrel's research looks at the number of parasitic infections in the clam Austrovenus stutchburyi in areas where commercial harvesting takes place and compares these with areas where there has been no harvesting. She also examines the effect of these parasites on juvenile clam mortality, growth, body condition and foot length.
|Mud snails were collected from Otago Harbour and their parasites were used to experimentally infect the juvenile clams and observe changes in their growth, body condition and foot length.|
|The trematodes encyst within the foot of the clam where they reduced foot muscle contractions and hinder burrowing behaviour.|
