摘要

Length–weight relationship (LWR) for the Red Sea roughy, Hoplostethus marisrubri Kotlyar, 1986 [Trachichthyiformes: Trachichthyidae], collected with a commercial shrimp trawler (n = 136) off Yanbu in the Red Sea at depths ranging between 662 and 667 m, is presented herein. Hoplostethus marisrubri can be distinguished by a combination of characters: dorsal-fin rays V–VI, 13; pectoral-fin rays 14–15; anal-fin rays II–III, 9; predorsal scales 19–20; distinctly enlarged lateral-line scales; and the dorsal fin without a black outer edge. In our study, a new maximum standard length of 130 mm was recorded. We estimated the length–weight relationship (LWR) parameters a and b for H. marisrubi as 0.033 and 3.17, respectively, which are new additions to FishBase. Based on the b value of the LWR, H. marisrubi has a positive allometric growth.
