“…LWRs can be used to convert length-frequency observations to biomass estimates while modelling an aquatic ecosystem (Kulbicki et al, 2005) and in converting length data obtained from back calculations on otoliths and scales. LWRs of other freshwater fishes from Indian rivers were previously reported by Baitha et al (2018), Borah et al (2018), Koushlesh et al (2018), Baitha et al (2017) and Nath et al (2017). The relative condition factor for L. calbasu, L. bata, L. rohita, L. dyocheilus and L. porcellus were estimated as 1.019± 0.023, 1.001 ±0.011, 1.013 ± 0.021, 1.005 ± 0.023 and 1.003 ±0.017, respectively (Table 2).…”

Length-weight relationship (LWR) of five species of the genus Labeo (Family: Cyprinidae) namely L. rohita (Hamilton,1822), L. calbasu (Hamilton,1822), L. bata (Hamilton,1822), L. dyocheilus (McClelland, 1839) and L. porcellus (Heckel, 1844), based on 214 specimens collected from Cauvery River in Peninsular India, were established. Sampling was carried out from December 2017 to December 2018 at around three months interval. The value of regression coefficient (b) ranged from 2.6147 (L. bata) to 3.2855 (L. dyocheilus). A new maximum length of 41 cm for L. porcellus has been recorded. For L. porcellus, LWR is established for the first time while for other species (except L. rohita); it is estimated for the first time from a peninsular river in India. Relative condition factor estimated for the five fish species did not show large scale variation (1.001 to 1.019).

“…For both the species, the LWRs were highly significant (p<0.01) and the coefficient of determination (r 2 ) values were 0.954 and 0.974 for O. pama and O. biauritus respectively. Baitha et al (2018) Nath et al (2004) and Hossain et al (2015). The observed differences in 'b' values may be due to the combination of one or more factors like habitat, area, seasonal effects, the degree of stomach fullness, gonad maturity, sex ratio, health condition, preservation techniques and length groups of studied specimens (Tesch, 1971).…”

“…Hossain et al (2015) described the LWRs of Otolithoides biauritus and O. pama from the Tetulia River, southern Bangladesh. Recently Baitha et al (2018) reported the LWR of O. pama from Ganga River, India. All these studies were based on pooled samples.…”

The length-weight relationships (LWRs) of Otolithoides pama (Hamilton, 1822) from the Hooghly-Matlah estuarine system of West Bengal were estimated. The study is based on 618 samples (298 male and 320 female) collected at monthly intervals for a period of 18 months (November 2016 to April 2018) from artisanal catch. No significant difference (p>0.01) was observed in growth rate for both the sexes. The ‘b’ values were estimated at 2.88, 2.84 and 2.86 with ‘r2‘values as 0.96, 0.95 and 0.95 for male, female and pooled samples respectively. The growth pattern was found to be negatively allometric. The month-wise mean ‘K’ value ranged from 0.70±0.07 to 0.78±0.07 for male and 0.71±0.05 to 0.89±0.11 for female. The length-wise estimated mean ‘Kn’ value varied from 0.92 to 1.17 for male and 0.76 to 1.29 for female indicating the moderately good condition of the fish in the study area. The results can be used for sustainable management and conservation of this commercially important species in this estuary

“…The length–weight data also provide significant clues on changes in environment and fishery practices over a period of time (Dubey et al., 2012). In the recent years, a large number of studies were conducted on the LWRs of fish species from Ganga and Brahmaputra basins (Baitha, Karna, et al., 2018; Baitha, Sinha, et al., 2018; Borah et al., 2017; ; Karna et al., 2018; Koushlesh et al., 2018; Nath et al., 2019). Among major rivers of India, the Cauvery holds a unique status in harbouring high number of endemic fish species owing to the remarkable habitat heterogeneity throughout its course since a major part of the basin lies within the Western Ghats biodiversity hotspot.…”

The present study estimated length–weight relationships (LWRs) for six indigenous fish species (Barilius gatensis, Salmostoma acinaces, S. boopis, Puntius amphibius, Hemibagrus punctatus and Ambassis miops) based on specimens collected from River Cauvery (including estuary) during July 2017–January 2020. The sampling surveys were carried out in three distinct sampling seasons, viz., the pre‐monsoon (March–May), the monsoon (July–October) and the post‐monsoon (November–February). Majority of the fish specimens dealt in the study were collected from multi‐meshed monofilament gill nets (mesh sizes 18, 30, 45, 60, 90, 110, 120 and 150 mm) operated by local fishers. For those sites situated in the protected areas, sampling was carried out by cast nets with prior permission from the local administration and the collected fishes were released back into river after length–weight measurements. The length measurements were noted as total length (TL) measured to the nearest 0.1 cm by using a digital Vernier caliper. A digital balance was used for weight measurements with an accuracy of 0.01 g. The study recorded a new maximum length of 48 cm for H. punctatus. The LWR data generated from the present study are significant for proper assessment of the stock status and their management, if collected together with other essential biological and physical parameters.
