Abstract

Introduction: This study aimed to investigate the meristic characteristics and morphometric relationships of the Penaeid shrimps that were caught monthly in the Khor Khoran international wetland from December 2020 to January 2022. This study aimed to investigate the meristic characteristics and morphometric relationships of the Penaeid shrimps that were caught monthly in the Khor Khoran international wetland from December 2020 to January 2022.

Materials & Methods: Sampling was done by using nets that were used by local fishermen in the area (with a local name of jelbily and with mesh sizes of 5 mm) and a number of shrimp samples were randomly selected every month. A total of 1274 shrimps were measured biometric data bioassayed.

Results: The meristic data results showed that in Penaeus merguiensis, the first dorsal tooth is often located after the second ventral tooth, and the distance between the first and second teeth is greater than the distance between the second and third teeth. In the Indian white shrimp, Penaeus indicus, the Anterior dorsal tooth is located after the third ventral tooth. The first dorsal tooth in Penaeus penicillatus is located before the first ventral tooth, and the distance between the first and second dorsal teeth was less than the distance between the second and third teeth. In jinga shrimp, Metapenaeus affinis, the telson had no lateral spines, and the number of dorsal teeth on the rostrum varied between 8-11. Also, this study is the first report of the presence of P. penicillatus in the southern waters of Iran.

Conclusion: Weight- length relationship for P. merguiensis, P. indicus, P. penicillatus and M. affinis, were calculated W=0.0065, W= 0.0077, W= 0.001 and W=0.6769, respectively.
