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.
