Abstract:

The Persian Gulf is part of the semi-closed seas linking through the Strait Hormuz to open sea. Bushehr province, with more than 600 kilometers of sea border, is one of the provinces of the Persian Gulf, in which fishing activities are of great importance. In recent years, due to abundant harvesting and environmental pollution, most of the Persian Gulf fish stocks have fallen, requiring detailed population surveys of aquatic animals. Green tiger shrimp belong to the genus Penaeus of the Penaeoidea family and is one of the most valuable species of the genus, accounting for more than 80 percent of its catch in the Persian Gulf. Considering the key role of these reserves in terms of ecology in marine ecosystems, especially aquatic fauna, and the provision of food for many commercial and industrial spiciest, more careful consideration is given to the study of biological dimensions, ecology, and the assessment of shrimp populations are essential. In present work, morphometric characteristics of different populations of green tiger shrimp were surveyed in five different stations in the Persian Gulf to study the demographic patterns of this valuable crop. For this purpose, a total of 50 adult shrimp samples were collected from 5 different aquaculture catchments. Then in the laboratory 16 morphomorphic traits were examined. The results of this study showed that except for total length (TL), abdominal length (ST), rostrum (R), length of lanes 3, 2 and 6 (L2, L3, L6), carapace width (WC) and body weight (W) was significantly different in other traits (p <0/05). Demographic studies based on Discriminant Function Analysis showed that the population of Mottaf is completely separate from other stations, which indicates a different climate in this part of the Persian Gulf.
