Abstract

In this research, age structure and GROWTH PATTERN of Perch (Perca fluviatils Linnaeus, 1758) from the Lahijan Amirkelayeh Wetland was studied on a monthly basis in a year. In total, 265 specimens were caught and the weight and length were measured and the age was determined by opercula and scale's reading. The age data showed that the fish were between 2+ to 6+. Male, female fish classified respectively in 12 and 13 length frequencies groups. The average instantaneous growth rate of perch showed that the age groups 2+ to 3+ with 0.461 grew faster than other groups and slowest growth belonged to age groups of 5+ to 6+ with 0.231. Condition factor of specimens showed that the highest one with 2.49 (r2=0.938) belong to female and the lowest one with 1.06 (r2=0.944) belong to male fish. Pauli's applied GROWTH PATTERN showed almost an isometric growth for total, male, and female fish and tendency to positive allometric growth. Total sex ratio (178 male to 78 female) showed a significant difference.
