“…Later, Gogoi et al (2021) studied the age, growth and mortality parameters of this fish from the Brahmaputra River. Recently, Khan et al (2022) studied the relationship between the length, otolith size, and weight of this fish from the Ganges River in Uttar Pradesh, India. The current study was conducted in the Tetulia River.…”

The near-threatened Ailia coila, commonly referred to as Gangetic ailia, is a catfish species in the Ailiidae family that is indigenous to Bangladesh, Pakistan, Nepal, and India. This study describes the comprehensive explanation of life-history traits of Ailia coila, including length-frequency distribution (LFD), growth pattern (length-weight relationships, LWRs and length-length relationship, LLR), form factor (a 3.0 ), condition factors (allometric, K A ; Fulton’s, K F ; relative, K R and relative weight, W R ), size at first sexual maturity (L m ), optimum catchable length (L opt ) and natural mortality (M w ) from the Tetulia River in southern Bangladesh. Additionally, L α , a 3.0 , L m , M w and L opt from various water bodies worldwide using the existing literature were calculated in this study. A total of 316 samples were randomly collected occasionally using traditional gear for a year from July 2021 to June 2022. With an accuracy of 0.01 cm and 0.01 g, each fish’s total length (TL), standard length (SL), and body weight (BW) were measured. The group from 10.00 to 10.99 cm TL was numerically leading and the b values of LWRs indicate positive allometric growth. The a 3.0 was 0.005 and K F was the best for assessing the well-being of A. coila. Additionally, W R indicates that the habitat was imbalanced with higher predators. The calculated L m , L opt and M w were 9.19 (~ 9.2 cm TL), 10.7 cm TL and 1.37 year−1 for A. coila in the Tetulia River, respectively. These insights are vital for future research and recommending suitable management strategies for A. coila in the Tetulia River and neighboring basins.
