“…Length–weight relationships (LWRs) are an important parameter in fish biology, ecology, physiology, fisheries assessment, management and conservation studies (Bhakta, Das, et al, 2019; Froese, 2006). Length–weight relationships are widely used in fishery biology to estimate the weight of an individual fish of a given length based on a known length–frequency distribution of the fish, with important implications in fish population dynamics (Froese, 2006; Froese et al, 2011).…”

Length-weight relationships of seven small indigenous fishes collected from the middle and lower stretch of the Tapti River in India were determined. The specimens were caught with drag nets (0 mm mesh size), gill nets (10-20 mm knot-to-knot mesh length) and scoop nets (0 mm) from the Maharashtra, and Gujarat state stretches of the Tapti River from November 2018 to December 2019. Digital calliper and digital balances were used to measure the total length (TL) and body weight (BW) of all fish specimens respectively. The growth coefficient b varied from 2.758 (Parambassis ranga) to 3.298 (Osteobrama cotio), and the LWRs were highly significant (p < .005). The present study established LWRs for the first time for seven fish species in the respective riverine habitat, including providing a new maximum length record for Corica soborna. The results of the present study will be useful for sustainable management and conservation of respective species in the river and its associated waterbodies.

“…The productive estuarine aquatic environment facilitates breeding and nursery grounds for fishes of diverse species, noting exploratory studies on ecologically and economically important species can provide a better understanding of fish biology, facilitating effective fishery management, since the relationships between total length, body weight and otolith dimensions remain unknown for many brackish waters and marine fishes in Bangladesh. Previously, O. pama studies have included population dynamics (Mustafa et al, 2019), length-weight relationships (Bhakta et al, 2019;Hossain et al, 2015) and condition factor (Bhakta et al, 2019). Detailed information on the relationship between O. pama size and otolith dimensions from the Meghna River estuary, however, is lacking.…”

The relationships between fish size, weight and otolith morphometry are useful for fisheries management, predator-prey studies and feeding habits. Accordingly, the main purpose of the present study was to determine the relationships between body length, body weight and otolith dimensions, and to calculate the length-weight relationship and condition factor for a Sciaenid fish Pama croaker, Otolithoides pama (Hamilton, 1822) from the Lower Meghna estuary, Bangladesh. Field sampling was conducted from September 2019 to March 2020. The length, breadth and weight were measured for each pair of sagittae, as well as the total length (TL), standard length (SL) and body weight (BW) for each specimen. A total of 246 fish samples were collected. The TL and BW of collected individuals ranged from 14.40 to 27.40-cm and 21 to 175-g, respectively. The calculated growth coefficient (b = 3.018 for males; 3.052 for females) were >3, indicating the fish follow a positive allometric growth.The mean Fulton's condition (Kn) values ranged from 0.674 ± 0.06 to 0.776 ± 0.07, exhibiting similar trends for all size classes. The relationships for fish size and otolith morphometry were described by linear regression models as TL = 0.048OL -0.308 (r 2 = 0.921); BW = 0.047OL + 6.252 (r 2 = 0.929); TL = 0.003OW -0.414 (r 2 = 0.836); BW = 0.003OW + 0.039 (r 2 = 0.81). The otolith length and weight exhibited a strong correlation (0.929 > r 2 > 0.805) with total length and body weight, while the otolith breadth exhibited a weak correlation. No significant differences between left and right otolith were observed (p > .05). Because the results of the present study indicated fish length and otolith growth have a positive relationship, this finding can be a valuable tool to evaluate fish growth by back-calculating the length of a fish from its otolith characteristics.

“…O. pama locally called 'Bhola' forms an important fishery in Hooghly-Matlah Estuary (Bhakta et al, 2020a,b). The species is mainly found in coastal waters, estuaries and rivers and thus occurs in freshwater, brackish and marine habitats (Talwar and Jhingran, 1991;Bhakta et al, 2019b;2020c). O. pama is distributed in the Ganga and Brahmaputra rivers and its estuaries in India, Burma, Sittang River, Malay Peninsula, Sumatra and Guinea (Talwar, 1995).…”

Pama croaker, Otolithoides pama (Hamilton, 1822) is one of the commercially important demersal fish of Hooghly-Matlah estuarine system, West Bengal, India. Reproductive biology of 618 samples of O. pama (Hamilton, 1822) collected from the Hooghly-Matlah estuarine system of West Bengal, India for a period of 18 months (November 2016 to April 2018) was investigated. The total length (TL), body weight (BW) and ovary weight (OW) of the samples varied from 100-384 mm, 7.29-470.71 g and 1.5-29.49 g, respectively. The sex distribution was 1 male for 1.07 female and the ratio did not differ statistically. The length at first maturity (Lm) was recorded as 183 mm for males and 196 mm for females. The reproductive activity was found throughout the year with three peak spawning season with high gonadosomatic index (GSI) values, i. e., during February-March, June and September-November. The absolute fecundity ranged from 4652 to 170688 eggs (24950±32441.2) and relative fecundity ranged from 96 to 808 eggs per g body weight (382±176.83). Fecundity exhibited a relatively higher significant correlation with ovary weight (r = 0.973, p<0.01), compared to total length, total weight and ovary length. Egg diameter frequency showed polymodal distribution, indicating that the species is a batch or asynchronous spawner.
