Length-weight relationship and condition factor in Sarda orientalis (Temminck & Schlegel 1844) (Family-Scombridae) fish from Karachi fish harbour.

Abstract

Sarda orientalis (Family-Scombridae) of assorted length (cm) and weight (gm) were obtained from Karachi fish harbor during January to December (2019) for measurement of length-weight relationship (LWR’s) and Fulton‘s condition factor (K). The range of length (57-60.8) and weight (2123-2641) were estimated. Total mean length (cm) (gm) (59.14±0.94) and weight (gm) (2336.32±114.21) were measured. LWR was estimated as W = 0.08166134 × L 2.5149 (log W = -1.088 + 2.5149log L). The highest mean of condition factor (K) (1.15±0.02) were measured in post-monsoon season. Assorted (ANOVA) analysis indicates that there is a significant correlation between weight, length, and season (p0.05).
