Length-weight Relationship and Relative Condition Factor of Two Dominant Species (Cyclocheilithys apogon and Notopterus notopterus) at Subang Lake, Selangor, Malaysia

Abstract

of Beardless barb and 344 individuals of Bronze featherback were measured and weighed. The mean total length of Breadless barb was 13.11 ± 1.31 cm with the mean weight of 31.88±9.93 g. The mean of the total length and weight of Bronze featherback was 16.05 ± 2.07 cm and 30.38 ± 15.63 g. Both fish species showed negative allometric growth with the exponent b value 2.884 and 2.886, respectively. The condition factor of Beardless barb (1.184 ± 0.134) and Bronze featherback (1.010 ± 0.163) obtained from this study reflects a fair growth condition based on K value by ABSTRACT Length-weight relationships and relative condition factors were conducted to provide information on fish species' growth conditions and general well-being in the freshwater habitat. This study was conducted using fish as a bioindicator for the health of the ecosystem.Cyclocheilithys apogon (Beardless barb) and Notopterus notopterus (Bronze featherback) are the most dominant species in Subang Lake. A four-month sampling was conducted to collect the sample of Beardless barb and Bronze featherback. A total of 422 individuals
