Abstract
In the present study about 277 specimens of Lethrinus nebulosus were used to determine some biological parameters which are needed in stock assessment in the region of Arabian Gulf on the Saudi Arabian coasts. The period of spawning was estimated using maturity indexes to April, Mai and June. This species is gonochoric, nevertheless some cases of hermaphrodism are noted. The length relationships were determined showing a correlation between total length and standard length, and between total length and fork length. The weight- length relationship is allometric minorante. The model of Von Bertalanffy was estimated for the studied species and it is as follows: Lt = 600 *(1-exp (-0.135*(t+1.69)) for both sexes, Lt = 600 (1-exp (-0.166*(t+0.746)) for females and Lt = 555 *(1-exp (-0.153*(t+1.62)) for males.
