The isopod Nerocila depressa is present on 54% of the market-sized white sardines (Sardinella albella) caught from an estuary in the Trat province of Thailand. The ventral part of the body, especially the upper pectoral fin, was the area most frequently infected by this parasite. Parasite length was positively correlated with fish length, which suggests that the parasites attach to the fish at a young age. At the site of attachment, the parasites erode the epidermis, dermis and muscular tissue of the Sardinella. Such pathology may cause mortality in many fish. Infestation of this parasite was proportional to the weight of the fish. This study reports a new host for N. depressa attachment and is the first report of S. albella infestation in the Trat province where other known host fish species are cultured.
