Abstract

Length-weight and length-length relationships were estimated for eight species occurring in the Hara Biosphere Reserve in the Persian Gulf. Specimens were collected quarterly by block net and drift gillnet from June 2017 to July 2018.  The b-values for length–weight relationships varied from 2.693 to 3.321. The study represents the first published information on LWRs for Hemiramphus archipelagicus (Collette & Parin, 1978), Lagocephalus guentheri (Miranda Ribeiro, 1915), and Triacanthus biaculeatus (Bloch, 1786) and first-time reports for FishBase. These species are ranked as rare in the sense that they have a restricted range.
