Abstract
Crustacean isopod parasites, particularly in the marine environment, are prevalent around warmer seas and can significantly impact local fish populations. Mothocya renardi, a notable species of isopod parasites, commonly infests fishes in shallow, turbid coastal waters. This study aimed to investigate the occurrence, taxonomy, and morphology of M. renardi infesting Strongylura leiura in the Arabian Sea around the northwest coast of India. Samples were collected from Dholai fishing harbor (Navsari District of Gujarat), during the post-monsoon months. Three specimens of S. leiura were found infected with pairs of male and female M. renardi in the brachial chambers, with all female parasites being brooded ovigerous. Detailed morphological analysis confirmed the presence of M. renardi, extending its known geographical range to the Arabian Sea.
