Overview

Field study reveals healthy condition factors and varied growth patterns in native freshwater fishes, suggesting localized environmental conditions dictate population well-being.

Key Points

  • To evaluate the length-weight relationships, growth patterns, and health status of five native freshwater fish species across seven mountain wadis.
  • Sampled N=1,896 freshwater fish across seven wadis in the Hajar Mountains, Oman, during March 2023 using foldable traps.
  • Measured body weight (0.01 g precision) and length to evaluate length-weight relationship parameters and Fulton’s (Kc), allometric (Ka), and relative (Kn) condition factors.
  • Length-weight models demonstrated a strong fit (R² ≥ 0.906), with growth coefficient b-values ranging from 2.833 to 3.352, reflecting predominantly positive allometric growth across species.
  • Mean Fulton’s condition factor (Kc) ranged from 0.902 ± 0.085 to 1.889 ± 0.288, while mean relative condition factor (Kn) clustered near 1.0, signifying overall healthy populations.
