“…The minimum and maximum total lengths of N. notopterus (Pallas, 1769) were varied between 10.00 cm and 33.25 cm with the estimated value of asymptotic length (  L ) 34.91cm which is higher than the value (33.8 cm) found by Kiran et al (2004) and Sani et al (2010); lower than the value (40 cm) found by Parameswaran and Sinha (1966). The value of Growth Coefficient (K) was 0.38 yr -1 for N. notopterus which were higher than the value (0.35 year -1 ) found by Amin et al (2006) and lower than the value (1.6 yr -1 ) found by Zafar et al (1998).…”

“…This species showed isometric growth with b value of 3.0 (Kalita and Rath 1996). Slightly dissimilar results were reported by Kiran et al (2004) which showed positive allometric growth in male N. notopterus (b = 3.2721) while negative allometric growth in female (b = 2.8483). Sani et al (2010) and Naeem et al (2010) have reported negative allometric growth (b = 2.99) and (b = 2.87) for both sexes.…”

Notopterus notopterus (Pallas, 1769) commonly known as bronze featherback is an important freshwater fish widely distributed in deep and clean waters in the rivers, beels, reservoirs and ponds. This study elucidates the length-weight relationship (LWR), relative condition factor and fecundity of N. notopterus collected from the river Brahmaputra in Dhubri, Assam, India. A total of 181 fish specimen were sampled. The LWR showed a positive isometric growth with uniform increase in height or width with increasing length. The value of a and b in males were 0.0120 and 3.06 respectively. In females, a and b were slightly higher being 0.0230 and 3.18 respectively. The coefficient of determination for combined sex was equal to 0.8572 (p < 0.001). The relationship between the fecundity and four variables viz. total length, body weight, gonadal length, gonadal weight were analysed and the relationship between the fecundity and gonad weight was much more significant than other variables considered. The current study might serve as a valuable guideline for establishing future biometric studies for fishes collected from this stretch of the river Brahmaputra.

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
