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

Abstract

Introduction: Striped piggy fish (Pomadasys stridens) is one of numerous species in the Persian Gulf Ecosystem and Marine Food Chain.
Materials & Methods: 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.
Results: 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.
Conclusion: Fish growth is influenced by biotic and abiotic factors, which are affected by geographical differences.
