Abstract

In this study, 104 specimens of sand melt caught in the Tonekabon County coasts in summer and autumn seasons (2015). The samples were fixed in 10% formalin and transferred to the laboratory for more studies. The length and weight average of A. boyeri caspia were obtained 10. 33 cm and 6. 76 g in summer and 10. 30 cm and 7. 46 g, respectively. The Length-Weight Relationship of this species in summer and autumn is and, respectively. Moreover, the results indicated a higher condition factor in autumn than summer. Pauly method was used to survey the growth pattern in this species. Based on result, the Sand Melt in the Tonekabon coast had a negative allometric growth in both summer and autumn, indicating a lower growth rate of weight than length in this species. In addition, the empty stomach index (CV) showed a relative overeating. The survey of the relative length of gut indicated carnivorous diet of A. boyeri caspia. Also, the study of fullness index showed that this species is in a good nutritional condition. The Food Preference Index showed that this species doesn’ t have the main food, and only the Gammaridae and Bosminidae were their sub food.
