Abstract: 

The aim of this study is to determine the length-weight relationships (LWRs) with of /388/ specimens of migrant fish Parupeneus forsskali caught in the Syrian Seawater during the period : 15/9/2019 to 22/9/2020, by different fishing tools, especially trammel nets. The following measurements were taken for each individual who were studied: the total length and weight to nearest 0.1cm and 0.01g, respectively.  The relationship of the length calculated for male and female thumbnail, has reashed values (b) calculated 3.0913 for males and 3.0629 for females. Thus it was observed that the calculated (b) value matched for the ideal value, that is, the growth of this type of standard Isometric. The value of appreciation (R2) was close to all individuals and was 0,9217 for females and 0,9473 for males and for all mixed individuals. The results of the morphological study of the stages of development of the male and female gonads morphologically in the studied fish species agreed with the hexagonal scale of gonad maturation in the teleost fish.

Key words: Parupeneus forsskali, Mullidae, L-W relationship, Morphology Gonads changes, Syrian marine waters.
