| Abstract | ||
| The stomach content of 1000 and 1293 specimens from males and females respectively of Marsupenaeus japonicus, inhabiting the western Mediterranean Egyptian coast, were studied monthly from May 2015 to April 2016. The aim of this study was to identify the diet items of M. japonicus based on the analysis of the stomach contents. The stomach analysis was carried out by using the frequency of occurrence (O %) and numerical methods (N %). The kuruma shrimp M. japonocus is omnivorous, but with an important carnivorous component, mainly on crustacean and fish remains. Represented data of this study indicated that M. japonicus has not food preference between sexes. Stomach contents of adult and juvenile specimens were similar. The quantitative analysis and seasonally variations in the feeding intensity was quite high during the summer, autumn and winter. | ||
