“…During this study, the maximum size of M. cavasius observed in the Jamuna River was less than half the maximum recorded value from the Cauvery River in southern India (Muralidharan et al., 2011). This indicates a decrease in the maximum sizes of individuals of these species landed within the Jamuna River system, signaling the need for urgent measures to conduct extensive studies on these species and provide more information for their management and conservation.…”

“…As samples of each species included individuals collected over several seasons, the parameters a and b should be treated as mean annual values. Due to the lack of literature references dealing with LWRs and LLRs for these species, result comparisons were not possible, except for M. cavasius from India (Sani et al., 2010; Muralidharan et al., 2011). Muralidharan et al.…”

The small indigenous species, namely Ailiichthys punctata (Day, 1871), Botia lohachata (Chaudhuri, 1912), Chanda nama (Hamilton, 1822), Laubuca laubuca (Hamilton, 1822) and Mystus cavasius (Hamilton, 1822), comprise an important component of riverine fisheries of Bangladesh. This study describes the length-weight relationships (LWRs) and lengthlength relationships (LLRs) of five threatened fishes from the Jamuna River, a distributary of the Brahmaputra River in northern Bangladesh. A total of 919 specimens from five species in five families used for this study were caught by traditional fishing gear, March 2010 through February 2011. The allometric coefficient (b) of the LWRs indicated negative allometric growth in A. punctata, B. lohachata, and C. nama (b < 3.00), but positive allometric growth in L. laubuca and M. cavasius (b > 3.00). Furthermore, the LLRs were highly correlated (r 2 > 0.978; P < 0.001). This study presents the first reference on LWRs and LLRs for these threatened species in Bangladesh. The results would be useful for sustainable management and conservation of the limited stocks in the Brahmaputra River ecosystem.

“…Variations in size class were found to be an expected phenomenon of C. reba in this study. When compared to other studies, the weight and total length of C. reba collected from Bergobindapur oxbow lake showed similar size variations (Narejo 2006, Muralidharan et al 2011, Hossain et al 2013, Jewel et al 2019. In total, 157 wild fish specimens with various phenotypic lengths were sampled using conventional fishing gears during the study, but it was difficult to harvest C. reba smaller than 12.24 cm TL throughout the sampling period, which can be ascertained either to the nonappearance or lack of small sized fishes in their respective habitats or mesh sizes of the harvesting nets (Hossain et al 2012b).…”

Cirrhinus reba, is a freshwater fish species which is distributed throughout the South Asian countries. The current study reports the detailed biometric indices of C. reba in the Bergobindapur oxbow lake (Baor) located in southwestern Bangladesh. The parameters assessed included length-frequency distributions (LFD), length-weight relationships (LWR), form factor (a3.0) and length at first sexual maturity (Lm) and four types of condition indices (i.e. allometric, KA; Fulton, KF; Relative, KR and Relative weight, WR).Conventional fishing equipment such as cast nets and monofilament fixed gill nets were used to collect samples from July to August 2019. Digital slide calipers were used to assess total length (TL), standard length (SL), fork length (FL), and trunk length (TrL), and body weight (BW) was quantified with an electronic balance with 0.01 g precision. Total 157 specimens with lengths ranging from 12.24 to 24.82 cm and weights ranging from 22.00 to 100.27 g were studied. The computed ‘b’ demonstrated negative allometric growth (< 3.00) in pooled sexes for the LWR. In this investigation, the mean of WR (100.36) did not differ significantly demonstrating that the environment was still in good shape. Furthermore, the size of C. reba at sexual maturity was estimated as 14.40 cm TL. The findings of this study would be worthwhile for the sustainable management of reba carp fisheries.
