Abstract

The length-weight relationship of a newly described catfish Pangasius silasi Dwivedi et. al., 2017 was studied from 88 specimens collected from the native distribution range of the species i.e. Nagarjuna Sagar Dam, Telengana, India. The total length and weight of the sampled fishes ranged from 290 to -590 mm and 240 to 2300 g respectively. Results of regression analysis showed that the regression coefficient (r²) values varied from 0.985 to 0.989. The average condition factor observed was 1.04 and 0.98 for males and females respectively. Positive allometric growth and condition factor of the species indicated the potential of the species for aquaculture. The information generated will also be useful in sustainable management and conservation of the species in natural waters.
