Study of some influence fish morphology characteristics Atherina boyeri caspia (Risso, 1810) fish Caspian on shores of the Salman Shahr

Fish and pelagic fish inflorescence of the Caspian Sea is across the Caspian Sea and river estuaries leading to it is distributed. This species of high economic value, but because the sturgeon lie about nutrition is important. This study explores some biometric characteristics and has been counting these species off the coast of Salman Shahr. Samples were collected using hooks were studied in the laboratory. A total of 30 biometric features and characteristics of the measured count was 3. Based on the results, the mean weight of 7.506 grams, average total length 102.487 mm. In numerical characteristics inflorescence fish off the coast of Salman Shahr, the number of first dorsal fin rays 6 eggs. The slope of the regression line between the length and weight were 2.441, and the type of negative allometry was determined. Compared to other studies showed (Postdorsal length) the differences in the characteristics of memory which can be due to differences between fish habitat and and ecological conditions of the region.
