Twenty specimens of triploid with weight and length ranging from 207-300g and 29-32cm; diploid 150-200g and 23-28cm Heterobranchus bidorsalis (Geoffroy St. Hilaire 1809) were subjected to morphometric and meristic characterization, length-weight relationship and condition factor evaluation. Triploid specimens had the higher values in all the parameters examined and were significantly different (P<0.005). Regression analysis of diploid and triploid show the ranges of values (K) of 0.802 1.453 and 0.838 0.906 respectively, for condition factor (k) while the relative condition factor values (Kn) ranged between 0.869 1.087 and 0.968 1.038 respectively. Weight increases directly as the total length increases for both diploid and triploid indicating isometric growth. The R2 in triploid was higher (96.8%) than in diploids (42.4%). In diploid progenies, the length by weight was significantly different (P<0.05) in triploid. Triploid progenies need no special adaptive environment or technique for rearing. Therefore, diploid and triploid progenies can be successfully cultured simultaneously under the same environmental condition.

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.

The current study describes the length-weight relationships and condition factor of Bombay duck, Harpadon nehereus from landings of Fishery Ghat, Chittagong. A total of 300 individuals caught by various mesh size of gill nets by commercial fishers were investigated from April 2016 to June 2016. On the basis of hypothetical cube law W=aLb, the variance of ‘b’ for both total length and standard length were estimated statistically (0.0090 and 0.0088 respectively). Using the value of t=1.96 at the 95% confidence limits for ‘b’ were estimated as 2.218 to 2.590 for total length-weight relationship and for standard length-weight relationship, 1.985 to 2.353 which indicated allometric growth pattern for both cases. The monthly relative condition factor during three months of observation (0.978, 1.033, and 1.097) showed no notable difference due to spawning strain, spent condition and lower feeding rate right after peak spawning season.Res.

The aim of this research is to know the length-weight relationship and condition factors of Mullet (L. subviridis) in Lereng Lagoon Purworejo Regency. The samples were collected monthly from February until May 2002. Total lengths and weights of the fish samples were measured. The length-weight relationships and relative condition factors measured were analyzed, and then t-test and least significant different test were conducted for length-weight relationships and relative condition factor respectively.The results indicated that the total length of Mullet had positive correlation to weight during observation. The length-weight relationships revealed that the slope values were significantly lower than 3 (allomatric growth) for each month of observation. The values of relative condition factors are vary from 0,9987 to 1,0162 for each size group for in all months. Those values are significantly not different to each other for all size and sex in all months.HUBUNGAN PANJANG-BERAT DAN FAKTOR KONDISI RELATIF BELANAK(Liza subviridis) DI LAGUNA LERENG KABUPATEN PURWOREJO

Length-weight relationship of 1119 specimens of Lepturacanthus savala (Cuvier 1829) from the Bay of Bengal, Bangladesh, was found to be curvilinear (W= 0.0003612 TL3.18) and linear (LogW= -3.44+3.18 LogTL) for both the sexes combined in arithmetic and logarithmic scales, respectively. The values of regression co-efficient (b) ranged from 3.002 to 3.337 (? ± 0.167) at 95% confidence limit. The regression 'b' value (3.18) followed the cube law and did not significantly (P>0.05) differ from the cube. The growth of the fish was found to be isometric. Relative condition factor (Kn) was also within the ideal range (0.9695 to 1.1155, mean 1.001± 0.033). Seasonal or in different length groups no dramatic changes in relative condition factor were observed. Length frequency distribution was found to be normal with maximum number of fish in mid length groups and minimum in the lowest and highest length groups.

The study was carried out to determine length-weight relationship and sex ratio of a freshwater fish Amblypharyngodon mola (Hamilton 1822) collected from Dekar haor of Sunamganj district during the period of January to August 2017. A total of 2000 fishes were collected for the study and categorized these fishes into three groups namely males, females and combined sexes. Among 2000 mola 777 were male and 1223 were female. Length-weight equations and the correlation coefficients obtained for males, females and combined ones were: males Y = –1.97 + 3.00X, r = 0.883; females Y = –2.30 + 3.41X, r = 0.914 and combined Y = –2.11 + 3.16X, r = 0.904. Female’s A. mola attained more weight with the increases in length. Value of correlation coefficient ‘r’ was 0.883 for male and exhibited highly positive correlation between length and weight. On the contrary, ‘r’ value for female was 0.914 and it had also strongly positive correlation between length and weight relationships. Length-weight relationship of A. mola for male, female and combined sexes showed allometric pattern of growth. Condition factor ‘K’ for male, female and combined sexes was 1.09, 1.05 and 1.06, respectively and indicated better condition of fishes. The highest sex ratio (1 : 2.05) was found in May and the lowest (1 : 1.33) was in February. Dominance of females over males throughout the year was observed with an average ratio of male and female 1 : 1.57. Therefore, results of the study indicate that the existing hydrobiological conditions of the haor are conducive for food availability, free movement, feeding and better growth of the fish. Asiat.
