Some morphometric relationships of Striped piggy fish, Pomadasys stridens (Forsskål, 1775) in coastal waters of Persian Gulf (Hormozgan province)

Striped piggy fish (Pomadasys stridens) is one of numerous species in the Persian Gulf Ecosystem and Marine Food Chain. This study was carried out to determine Length-Length and Length-Weight Relationships of striped piggy fish. Sampling was performed for 8 months from January 2020 to May 2021 in the waters of Hormozgan province.  During this period some morphometric relationships of 366 specimens were measured The minimum and maximum Fork length and Total weight were recorded at 43 mm, 198 mm, 1.35 g and  139.27 g respectively. Linear regression relationships between lengths (Total length, Standard Length and Fork Length) for this fish showed that there were positive correlations between these characteristics. R2   parameter for Total Length-Fork Length, Total Length-Standard Length and Fork Length-Standard Length Relationships are 0.9978, 0.9956 and 0.9968 respectively. The analysis of the b value for length-weight relationships indicated that the growth pattern in this species is negative allometric. The parameters a, b, and R2 for length-weight relationships were 0.00002, 2.9761 and 0.9943 respectively.
