Abstract

Study of dietetic diet of Psettodes erumei dandelion on the coast of Sistan province In the Oman Sea, 173 samples were taken at the time before Manson and after Manson in 2011 In this regard, nutritional factors like Determination of food priority index, empty stomach filling and relative length of the intestine were investigated. The gastric emptying index (CV) was found in all the examined samples This fish is a medium with moderate nutrition. It was also determined by the time of the analysis of this index that This fish is a species with moderate nutrition. It was also determined by the time of this index This species has a moderate nutrition before and after the manson. The Indicator Length Index (RLG) for this species indicates that the spittoon fish is a part of the carnivorous fish, and its diet includes: fish, shrimp Crab, Scalo, Marine Tetaya, Fish eggs, Worm, etc. Fat preferences were obtained for 88% of fish, 8% for crustaceans, 2% for shellfish and 2% for other fish. Fish, therefore, was recognized as the main source of dental plaque. Investigating the relationship between length and weight showed that the growth of this fish with allometric growth factor (26.23 b) was. Also, the male sex ratio was 1.22: 0.78.
