Knowledge on food and feeding is essential to attempt culture possibilities of S. canaliculatus in Oman.
Similarly, study on the length-weight relationship helps to determine the mathematical relationships between the two variables so that if one is known the other can be computed and to calculate the variation from the expected weight for the length of the individual or groups of fish (Le Cren, 1951).
Further, the estimation of a and b parameters of length-weight relationship is important for stock assessment (Vivekanandan, 2005).
The present paper deals with the stomach content analysis, hepato-somatic index (HSI) and lengthweight relationship of S. canaliculatus from the Arabian Sea coast of Oman.
