The cycloid scales reveal the presence of a distinct larval mark under the scanning electron microscope. A linear relationship between total fish length and lateral scale radius was observed. The exponent of the length-weight relationship was 2.519 and 3.094, the harvestable size 29.7 and 26.0 cm (total length), and the ultimate size based on Walford’s graph 76.0 and 64.5 cm in Gobindsagar Reservoir (Himachal Pradesh), and Harike Wetland (Punjab) respectively.
Cykloidalne łuski wykazywały pod mikroskopem skanningowym wyraźne pierścienie narybkowe. Stwierdzono zależność liniową między długością całkowitą i bocznym promieniem łuski. W populacjach ze Zbiornika Gobindsagar (Himachal Pradesh) i bagien Harike (Punjab) wykładnik w równaniu zależności ciężaru od długości wynosił 2.519 i 3.094, wymiar ochronny 29.7 i 26.0 cm (długość całkowita), a teoretyczna długość maksymalna odczytana z wykresu Walforda 76.0 i 64.5 cm.
