Length-weight relationship and condition factor of Japanese Weather Loach (Misgurnus anguillicaudatus, Cantor, 1842) in selected Municipalities of Mountain Province, Philippines
Abstract
The length-weight relationship and condition factor of fishes is a great importance in fishery assessment studies since it provides information about their growth, general wellbeing and fitness in their habitat. This study was conducted to determine the sex ratio, length-weight relationship, condition factor and size distribution of Misgurnus anguillicaudatus (Japanese weather loach) collected in selected municipalities of Mountain Province. A total of 308 M. anguillicaudatus from December 2022 to February 2023 were studied. There were 124 males and 184 females. Female loach dominated the male (1:1.48) with 5.99 level of significance. Length-weight relationships of male M angillicaudatus showed negative allometry (W=1.11 L 2.48) indicating that length increases faster than weight. Female also showed negative allometry (W=0.16 L 2.48) Combined sex showed negative allometry with value of W=0.12 L 2.72 Combined data from the three stations revealed that females have higher K value than males with a mean K value of 0.43 in males and 0.46 in females. Size distribution analysis showed that female loaches have 7-8cm in length ranging from 8-9cm and a common weight of 4-5 grams. Meanwhile, male loaches have 7-8cm in length and 1-2 grams in weight. Tus female loaches are longer and heavier than male loaches.
