Tade gray mullet (Chelon planiceps) forms a lucrative fishery in the Hooghly-Matlah estuarine system. During eight months of investigation 232 specimens were examined to study length-weight relationship and relative condition factor (Kn). The length and weight of fish was varied from 41 to 283 mm and 0.81 to 208 g respectively. Two length-weight relationship equations were obtained from the analysis, W=0.0000397L2.952 for <187 mm size group and W=0.0000406L2.834 for >187 mm size group. The size at first maturity was recorded as 187 mm. The b value was not significantly different from 3 indicating isometric growth. The monthly mean Kn for the male and female were 1.041–1.125 and 1.009–1.236 respectively. The highest Kn value was recorded in July for both the sexes, which may be due to advance maturity stages. The present study will be useful in the context of biological management of mullet fishery as well as to find out aqua-farming potential of Tade gray mullet.

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).

The Peppered loach, Lepidocephalichthys guntea is the least concerned freshwater species, commonly found in India, Pakistan, Nepal, and Bangladesh. In West Bengal, it is popularly known as “Guntey” & it has commercial and food value. The current study aimed to the estimation of the length-weight relationship, condition, and relative condition factor (Kn) of the fish species Lepidocephalichthys guntea, habitats of Kangsabati river in the District West Midnapore, West Bengal, India. Total 161 numbers of species were collected between August 2019 to July 2020 and considered for examination. The fishes ranged from 5.4 to 10.7 cm in total length & 0.72 to 9.73 g in weight. The scatter diagram exhibits a linear relationship between the log length & log weight. The female species has a higher “b” value (b=3.452, P<0.05), which is greater than 3 which justifying a positive allometric growth. The parabolic equation among total length and weight of L. guntea is labeled as W= 0.008744991 L 2.7496 for males, W= 0.002153098 L 3.452 for females & W= 0.007575793 L 2.8155 for the combination of male and female species. Higher r2 (0.859, P<0.05) value in combined of male & female justifying a strong relationship between length and length. The mean condition(K) & relative condition factor (Kn) values were found to be the height in the male category with "K" value 0.654 & "Kn” value1.174 respectively indicating the well-being of the species. Although, this species does not sternly follow the cube law & shows a well status of health condition in their natural habitat.

This study aims to determine the length-weight relationship (LWR) and evaluate the condition factors of the tropical sand goby, Acentrogobius caninus (Valenciennes 1837), in Pabean Bay West Java, Indonesia. The sampling was carried out once a month from January to December 2015, and during that period, 152 samples were collected. The LWR is W = 9 x 10-6 L-3.0356. The growth pattern of tropical sand goby is isometric (b=3). The monthly relative condition factor ranged from 0.798 to 1.322 (average: 1.028).
