Length–weight relationships of four fish species caught in the Northern Persian Gulf (Horomzgan waters, Iran)

Summary Length–weight relationships (LWRs) for four little-known fish species collected in the northern Persian Gulf (south of Iran) are presented, namely, Leiognathus lineolatus, Grammoplites suppositus, Eupleurogrammus muticus and Acanthocepola abbreviate. Thus far, these are the first LWRs for these species in the international scientific literature.
