Length-weight relationship and condition factor of male and female Japanese weather loach (Misgurnus anguillicaudatus) grown in ponds in Bauko, Mountain province, Philippines

Abstract

This study was conducted to determine the equation parameters of length-weight and condition factor of male and female Japanese weather (Misgurnus anguillicaudatus) loach collected from Bauko, Mountain Province, Philippines. From the 78 pieces of collected loach, 47 were males and 31 were females. Female loach (total length = 10.012 cm, weight = 4.161) were longer and heavier than male loach (total length = 10.152 cm, weight = 4.687). Size 9 to 10 cm was the most common size for male loach and 11 to 12 cm for the female. The growth of male and female loach was described as positive allometric because computed b was greater than 3 with length-weight relationship equation of W = 0.0623 L3.335 for male and W = 0.057 L3.433 for female. Condition factor of male loach (K = 0.171) was slightly higher than female loach (K = 0.140).
