Trichiurus lepturus L. is a commercially valuable bentho-pelagic fish inhabiting continental shelves and slopes worldwide. In the present study 74 specimens of T. lepturus were caught in the Persian Gulf, 12 of which were infected with female Brachiella trichiuri Gnanamuthu, 1951. They were attached firmly to the branchial arches of the host, and had a mean body length of 4.56 ±0.30 mm. Prevalence, mean intensity (±SE) and mean abundance (±SE), ofinfection were 16.2%, 0.38 ±0.14 and 2.33 ±0.61, respectively. This is the first record of B. trichiuri from the Persian Gulf. %U https://ijab.um.ac.ir/article_25098_6fd7d5da2d9c0f50235eae3d710a9b87.pdf
